Starting up and logging in
Logging off and turning off your Mac
Putting your Mac to sleep
Resuming where you left off
There's something about the Mac's startup chime. Most computers today play a sound as they start up, but the Mac started the whole idea decades ago. And even today, its sound has the right length and warmth—not too long, not too loud, and comfortably familiar.
That chime tells you that the Mac has in fact started and that basic hardware elements inside your Mac (hard disk, processor, memory, and so on) are all operational. After this chime sounds, Mac OS X tests the Mac's hardware (that's when you see the gray screen with the Apple logo and the spinning-wheel indicator), and then actually loads Mac OS X itself (that's when the screen turns blue). When you see the menu bar at the top of the screen and your desktop background has loaded, you know Mac OS X is ready to go.
The entire startup—also called boot—process takes about 30 to 45 seconds, depending on the speed of your Mac. Note that on faster Macs, some of the events may pass too quickly for you to notice.
Starting up your Mac
You start a Mac running Mac OS X 10.7 Lion in the following ways:
• Press the power button on the Mac.
• Press the power button on some Apple Cinema Display LCD monitors. Note that on some older models, the power button may simply switch the display off; the Apple LED Cinema Display does not have a power button.
Dealing with Startup Problems
If your Mac does not start up correctly or at all, try booting up from another boot disk (if you have one; it can even be the installation DVD of the previous [Snow Leopard] version of Mac OS X) and make sure the startup disk still contains its folders and files (in case it was accidentally wiped out or corrupted, such as during a power failure). You also can run utilities such as Disk Utility from a Snow Leopard installation DVD to try to repair any disk issues, as Chapter 6 explains. Third-party fix-it tools such as TechTool Pro ($100; www.micromat.com) enable you to create a bootable partition on your hard disk from which you can run its repair utilities.
If you're an advanced user (or a brave one), the Mac has three special startup modes you can use to troubleshoot a Mac that is not starting up correctly. One is single-user mode (press and hold Ô+S during startup), which boots you into the Mac's Unix core, where you can type Unix commands to explore and troubleshoot the system. Appendix D has more information on working with Unix.
The second special startup mode is verbose mode (press and hold Ô+V during startup), which displays a list of all startup activities and any error messages. This may help you identify the problem (such as a login item that is corrupt and needs to be deleted); you'll have to boot from a different disk to delete or modify any such files if the Mac won't boot from its normal startup disk. Note that neither single-user or verbose mode works if you've used Firmware Password Utility to protect the Mac from unauthorized use, as Chapter 26 explains.
The third special startup mode is the new Recovery System (press and hold Ô+R during startup), from which you can run diagnostic utilities such as Disk Utility (see Chapter 6) and reinstall Mac OS X if necessary, as Appendix A explains.
Note
Check whether the Mac has already been turned on and is in sleep mode. In this case, the screen is dark, so it's easy to believe the Mac is turned off. You can tell if the Mac is in sleep mode if a light is pulsating on its case. This is a visual cue that the Mac is asleep; the pulsing light is meant to evoke snoring. If the Mac is asleep, tapping the mouse, touchpad, or keyboard wakes it up. But don't panic if the Mac is asleep and you press its power button: That wakes it up as well, though usually you'll get a dialog box asking if you want to shut it down, put it to sleep, or restart it; just click Cancel to keep it on.
Choosing a startup disk
By default, Mac OS X starts up from your primary disk—the hard disk inside your Mac. But it can start from other disks as well, such as DVDs and external hard disks. It can even start up from a disk image on the network. You might start from a DVD—such as the previous Mac OS X Snow Leopard's installation DVD—to run Disk Utility on a non-starting primary disk. You might start up from a bootable external disk that contains applications (including the Mac OS X Lion installer) or setup configurations you are testing (something developers and IT staff might do, but not regular users).
To choose your startup disk, you have several choices:
• Press and hold Option as the Mac's startup chime begins; a screen appears showing icons for each disk available to boot from (you can release Option then). Select the desired disk by using the mouse or touchpad or by pressing ← or → until the desired disk is highlighted (an ↑ icon button appears below it). Then press Return or click the ↑ icon button to boot into the selected disk.
• Press and hold the C key as the Mac's startup chime begins to start up from a CD or DVD. Note that this method is guaranteed to work with Apple's SuperDrives, which come with every Mac but the MacBook Air (and you can buy an external one for that laptop). If you have another manufacturer's DVD drive in or attached to your Mac, it may or may not be bootable.
• Press and hold the D key as the Mac's startup chime begins to start up from the first internal disk in a Mac that has multiple internal disks (meaning a Mac Pro).
• Press and hold the N key as the Mac's startup chime begins to start up from the network. (A network startup disk image must be properly configured and enabled, and the Mac must be connected to the network server that hosts the disk image.)
• Press and hold the T key as the Mac's startup chime begins to boot the Mac into Target Disk mode, which lets another Mac connected to it via a FireWire cable see it as an external disk.
• Boot your Mac from its default disk, and then choose 9781118023761-ma001.eps ⇒System Preferences. Go to the Startup Disk system preference (by clicking its icon or choosing View⇒Startup Disk), choose a startup disk from the list, and click Restart. Note that this startup-disk choice remains in effect each time you start the Mac until you change the Startup Disk system preference again. (By contrast, pressing and holding one of the keys during startup changes the default startup disk for just that one time.)
Note
A system preference is the method that Mac OS X uses to store user preferences on how Mac OS X operates. Some third-party services that work across applications also install system preferences. They're all presented in the Systems Preferences application, which is available at all times from the Ú menu. Chapter 28 surveys the system preferences.
Logging in to Mac OS X
After the Mac has finished its startup process, the login procedure begins. The login procedure essentially identifies you to the computer, as a security measure, to ensure that only people authorized to use your Mac can access it; it also serves a second purpose of activating your personal workspace (called a user account, explained in Chapter 27), which contains your applications, preferences, and documents.
The login process is mandatory when you start (or restart) the Mac, but you may never see it occur. That's because by default Mac OS X automatically logs into the primary user account that was created when you first installed Mac OS X. Thus, whenever a user turns on the Mac, he or she is taken directly to the desktop and can begin using the computer.
Login window options
It is possible to disable the automatic login (Chapter 27 explains how to set up user accounts and login options). If you disable automatic login, the Mac asks for your username and password before logging in to your user account and taking you to the desktop.
New Feature
The login window in Mac OS X Lion has been redesigned for a slicker look. But it works the same way as in previous versions of Mac OS X.
You might disable automatic login for a Mac used at an office or other public space, so no one but you can use your computer after it is shut down. If automatic login is disabled, you might see one of two login windows when you start the Mac:
• List of users: One login window option presents a list of users, where you click your name or the icon representing you from the list of users (for Macs that have multiple accounts set up, such as for a family computer), and then enter your password in the field that appears. A check mark appears to the left of the currently logged-in user name. (If you accidentally selected the wrong user from the list, you can click the ← icon button to the left of the username to return to the list of users.)
• Name and password: The other login window option presents a Name text field and a Password text field, and you must type both to log in. This is meant to be more secure, so a visitor must know or guess both the username and password.
The login window also appears after you log out of Mac OS X (a process explained later in this chapter) or when you switch users by using Mac OS X's Fast User Switching feature to let people switch from one user account without restarting or logging out; Chapter 27 explains how to set up and switch accounts.
Password entry
If you enter your username or password incorrectly, the login window shakes sideways. The Password text field also clears so you can reenter the password. Note that the Name text field does not automatically clear; for security reasons, Mac OS X does not inform users if they have entered a wrong username. If you incorrectly entered the username, press the Tab key to highlight the text in the Name text field, so you can reenter it.
Note
Passwords are case-sensitive, so capitalization must match that of the password as originally set up.
If you enter the password incorrectly three times in a row, a password hint appears at the bottom of the screen. Clicking the Forgot Password button also reveals the password hint. (You enter password hints when creating a user account.)
New Feature
Clicking the ? icon button on the right side of the password field when logging in opens a pop-over that has an option for resetting the password using your Apple ID, if you enabled that capability during installation (see Appendix A). That pop-over also shows your password hint, should you want to see if before it's automatically displayed after three failed login attempts.
The login window's icon buttons
In the login window, three icon buttons appear at the bottom of the window: Sleep, Restart, and Shut Down. You can use these immediately, instead of having to log in to the Mac first. They come in handy when you accidentally turn on the Mac and want to put it back to sleep or shut it down.
You can configure Mac OS X so that the Sleep, Restart, and Shut Down buttons do not appear in the login window. To do so, choose 9781118023761-ma001.eps ⇒System Preferences and go to the Users & Groups system preference, click the Login Options button, and then deselect the Show Sleep and Shut Down Buttons option. By coupling this setting with the use of the Firmware Password utility explained in Chapter 26, you can make it all but impossible for someone to circumvent the requirement to log in.
Turning Off and Logging Out
When you've finished using your Mac, you have several options:
• Put the Mac to sleep.
• Leave the Mac on until the screen saver engages and then, later, the Energy Saver system preference settings put the computer to sleep automatically. (See Chapter 28 for details about the Desktop & Screen Saver and Energy Saver system preferences.)
• Log out of your account so people cannot access your Mac without first entering your (or their) login password.
• Shut down the Mac, which logs out of your account and closes the operating system, before switching off the power. This option saves energy and provides greater safety in case of power failure.
• Restart the Mac. This isn't really a way to finish working with your Mac; rather, it's an option typically used to complete the installation of certain system updates or to change startup disks.
Caution
If you cut the power to a Mac without first switching it off (either by pulling the plug or by removing the battery from a MacBook), you risk damaging the files on your Mac. Although this damage may not be immediately noticeable, an accumulation of damage could eventually cause problems, such as applications no longer working correctly or files missing data. Always shut down before disconnecting the power source.
Logging out of Mac OS X
You can log out of Mac OS X when you have finished using your computer. This provides an additional level of security over putting the Mac to sleep because it requires people to enter a password before they can begin using the computer. Logging out of Mac OS X is also a way to switch from one user account to another.
You can log out of Mac OS X by choosing 9781118023761-ma001.eps ⇒Log Out username or by pressing Shift+Ô+Q. Either way, a dialog box appears that provides two buttons: Log Out and Cancel. Click Log Out or press Return to immediately log out, or wait 60 seconds for the Mac to do it for you. Click Cancel to resume working on the Mac, using your current user account.
You also log out when switching to another user account, as Chapter 27 explains.
When you log out, Mac OS X quits all running applications and then displays the login window. From there, select a user account and enter the corresponding password to log in as that user. You also can click the Sleep, Restart, or Shut Down icon buttons if you meant to do one of those actions instead of logging out.
Putting your Mac to sleep (and waking it up)
When you're not going to use your Mac for a while, you can save energy by putting it to sleep. When you want to start using your Mac again, you can quickly wake it up. Waking up the Mac is much quicker than starting it up from being powered off.
It's usually good to let the Mac sleep during the day when you're not using it, because Mac OS X does some background maintenance when asleep that helps keep it operating smoothly.
You can put your Mac to sleep in any of the following ways:
• If you have a MacBook, simply close the screen lid.
• Choose 9781118023761-ma001.eps ⇒Sleep.
• If you are using a keyboard with an Eject key, press Control+Shift+Eject or Option+Ô+Eject to immediately put the Mac to sleep. Or press Control+Eject, and either click the Sleep option from the dialog box that appears or press the S key.
• Press the power button on your computer (or on your Apple display, if it has a power button). Then click the Sleep button in the dialog box that appears or press the S key.
• Log out of your Mac, and click the Sleep icon button in the login window that appears.
• Choose 9781118023761-ma001.eps ⇒System Preferences, go the Energy Saver system preference (see Chapter 28), and set the automatic go to sleep
time by using the Computer Sleep slider. That makes the Mac go to sleep automatically after it's been inactive for the specified time (meaning you haven't touched the mouse, touchpad, or keyboard and that no applications are running that are reading from or writing to a disk).
You can wake up your Mac in any of the following ways:
• If you have a MacBook, simply open the lid.
• Press any key on the keyboard. (To prevent the keypress from inserting text into an active document or text field, it's wise to get into the habit of using the Shift key as your wake-up key.)
• Click or move the mouse or touchpad.
Note that when you awaken a sleeping Mac, you may get a login window in which you have to enter your password. The login window also has two icon buttons: Cancel, which puts the Mac back to sleep, and Switch User, which lets you log into a different user account. (The login window appears if you configured the Security & Privacy system preference to require a password to reawaken a Mac, as Chapter 26 explains.)
Shutting down the Mac
While you can leave your Mac permanently running or let it go to sleep, you may want to completely switch it off at the end of the day. That reduces energy usage and makes it less likely the Mac could be damaged due to heat buildup or an electrical surge.
You can shut down a Mac several ways, including:
• Press the power button on your Mac (or your keyboard if it has one), and click Shut Down or press Return when the confirmation dialog box appears onscreen.
• If you are using a keyboard with an Eject key, press Control+Eject and click Shut Down or press Return in the dialog box that appears.
• Choose 9781118023761-ma001.eps ⇒Shut Down. Click Shut Down or press Return when the confirmation dialog box appears, or you can wait 60 seconds and the Mac shuts down automatically.
• Log out and click the Shut Down icon button in the login window.
When you go through the shut-down process, Mac OS X tells all open applications to quit and proceeds to shut down. If any applications have unsaved data, you are prompted with a Save dialog box before shutting down.
Tip
When shutting down, watch the desktop until the screen goes blank, which lets you know the Mac has actually shut down. When you shut down Mac OS X, it first tries to quit all active applications, but applications may not quit if they have unsaved documents. In this case, the applications present a dialog box asking if you want to save the unsaved documents, and the shutdown is delayed. If you walk away, you'll come back only to find that the shutdown didn't complete, and then you have to address the unsaved documents, wait for the Mac to shut down, and start it again to be able to use the Mac—a process that can be quite frustrating.
Note
You can use one other method to shut down the Mac: a forced shutdown. This can be handy in the event of a system crash, when there is no other way to shut down or restart the Mac. To use this method, simply hold down the power button for at least five seconds. However, you should avoid a forced shutdown if at all possible: Any unsaved document data is lost, and it is possible to cause damage to the system.
Restarting the Mac
You need to restart Mac OS X far less than many other operating systems such as Windows. That's because Mac OS X is very stable and doesn't require a restart to clear its memory as Windows does. Plus, many applications can be installed in Mac OS X without requiring a restart to activate their features. Still, sometimes you need to restart the computer after installing some software updates (such as Apple's Mac OS X software updates) or when installing some applications.
You can use the following methods to restart the Mac:
• Press the power button on your Mac (or on certain Apple-branded monitors). When the confirmation dialog box appears, click Restart.
• If your keyboard has the Eject key, press Control+Eject. In the dialog box that appears, click Restart.
• If your keyboard has the Eject key, press Control+Ô+Eject; the Mac begins to restart immediately.
• Log out and click the Restart icon button.
• Choose 9781118023761-ma001.eps ⇒Restart. When the confirmation dialog box appears, click Restart or press Return—or simply wait 60 seconds and let the Mac restart automatically.
During the restart process, Mac OS X tells all open applications running in the system to quit. If an application has an open document with unsaved changes, it asks you if you want to save the changes before quitting. Only when all the applications have quit does the Mac shut down and then start back up again.
Resuming Where You Left Off
A feature that iPhone, iPod Touch, and iPad users love is that when they turn off their device or put it to sleep, they pick up where they left off when they turn on or reawaken their device. Mac OS X Lion can do the same.
When you shut down, log out of, or restart your Mac, the confirmation dialog box has the Reopen Windows When Logging Back In option, as Figure 1.1 shows. If you want Mac OS X to reopen the currently open applications, documents, folders, and disk windows the next time it starts up or logs in to the same user account, make sure that option is checked before you confirm the shutdown, logout, or restart.
New Feature
The option to have applications and windows reopen upon startup or login is new to Mac OS X Lion.
FIGURE 1.1
The logout, restart, and shutdown confirmation dialog boxes all present an option to reopen the current windows when you log into or start the Mac.
9781118023761-fg0101.epsSummary
Starting up the Mac is as easy as pressing the power button, but more sophisticated capabilities exist when you need them, such as the ability to start up from different disks and to require login so only authorized users can access the Mac. This combination of simplicity and rich capabilities extends to the Mac's option to go to sleep, restart, and shut down, as well as to switch among authorized users.
And new to Mac OS X Lion is the ability to have the Mac remember what windows were open when you log out, restart, or shut down and automatically reopen them when you next log in or start the Mac.
Chapter 2: Discovering the Finder
IN THIS CHAPTER
Learning the Finder basics
Working with clicks, taps, and gestures
Understanding the desktop
Using menus
Working with the Dock
Working with Exposé, Spaces, and Mission Control
When the Mac has started up and you have been through the login processes, you are taken to the Mac OS X desktop, where you can begin to use your computer. It's the Mac desktop and the associated controls that most people think of when they think of Mac OS X. But what you're really seeing and interacting with is the Finder, the part of Mac OS X that manages your interactions with disks, folders, and files (both documents and applications).
The desktop is the screen with icons, folders, and windows. By default, the desktop has no icons on it. But most people configure the Finder to display the startup disk and other connected disks along the right side of the desktop, using the Finder's Preferences dialog box, as explained in the Adjusting Finder Preferences
section in Chapter 3.
At the bottom of the desktop, you see the Dock. This horizontal bar contains icons that represent quick shortcuts to applications and files. At the top of the screen is a menu bar that changes depending on the application in use, but by default is the Finder's menu bar. (The Finder is the application that you use to manage the Mac itself, letting you work with files and folders.)
The Finder has several major components that you interact with routinely, as Figure 2.1 shows:
• Menu bar: The menu bar is permanently available at the top of the Mac OS X screen, providing universal functions in the 9781118023761-ma002.eps menu, application-specific menus to its right, and icon shortcuts to various Mac OS X and third-party applications on the far right.
• Desktop: The canvas on which windows and other icons appear is called the desktop.
• Dock: The Dock is a tray of applications that by default is positioned at the bottom of the screen; you can configure what appears in the Dock and use it for quick access to applications and some special Mac OS X folders.
• Finder windows: When you open a disk or folder, the Finder shows its contents in a Finder window, which also provides quick access to other disks, folders, and special Mac OS X locations. Chapter 3 explains how to work with Finder windows.
• Icons: Disks, folders, documents, and applications are all represented as icons in Mac OS X windows, the Dock, the desktop, and other locations. These icons are selectable using a mouse or touchpad, so you can open them, move them, delete them, and otherwise work with them. You also can navigate them and edit them using the keyboard. Chapter 3 explains how to work with icons and disks, and Chapter 4 explains how to work with files and folders.
FIGURE 2.1
The basic Finder elements are the menu bar (top), disk, folder, and file icons (at right and below the menu bar), and the Dock (bottom). The canvas on which they rest is called the desktop.
9781118023761-fg0201.tifThe rest of this chapter explains how to use the Finder's major user interface capabilities. Chapter 3 explains how to use the Finder itself as an application and how its Finder windows work. Chapter 4 explains how to work with the disks, folders, and files you access via the Finder. And Chapter 5 explains how to search for files and information on your Mac via the Finder's Spotlight search tool.
Using Input Devices
To work with the Finder, you need to use input devices—the Finder can't read your mind, after all. The primary input devices are a keyboard, which is used both for text entry and to issue commands, and a mouse or touchpad, which is used to select items and then open, move, delete, or perform other manipulations on them. Some functions use multiple input devices at the same time. Mac OS X also can use speech commands, as described in Chapter 8, for text entry, issuing commands, and item manipulations.
Working with the keyboard
The Mac keyboard is very much like any typewriter's or computer's keyboard: It provides the keys for letters, numerals, and punctuation, as well as special keys to manipulate the text, such as Shift to capitalize letters and access some symbols, Caps Lock to capitalize all letters typed, Delete and Forward Delete to remove text, and Return to add paragraph breaks.
But the keyboard also has keys that never existed in a typewriter. There are modifier keys that are used in combination with each other and other keys to access special characters and to issue commands—Command (Ô), Option, Control, Esc, and Fn, as well as Shift—and there are shortcut keys called F keys (because they are labeled F1 through F12 on most Mac keyboards and F1 through F16 on others) to access special functions. Most Macs also have an Eject key to eject any DVD or CD inserted into the Mac. And some Mac keyboards have a Help key.
Note
If you're a Windows user, note that the Ô key is equivalent to the PC's Ctrl key, Option is equivalent to Alt, Delete is equivalent to Backspace, and Forward Delete is equivalent to Del. The Mac's Control key has no PC equivalent. Also, recent Macs don't have a Num Lock key; some keyboards assigned F6 to that function, but the Num Lock key is all but disappearing from Macs now.
You use the cursor keys (commonly called the arrow keys) to move up, down, left, and right. Some keyboards, called extended keyboards, have additional navigation keys such as Home, End, Page Up, and Page Down, as well as a numeric keypad.
Here's what the special keys do:
• The Ô key (Command) is the most-used modifier key for issuing commands. This key has had several labels over the years on various keyboards: Command, Cmd, Ô, and 9781118023761-ma002.eps .
• The Shift key is used both to capitalize text and as a modifier key in keyboard shortcuts. In Mac OS X and in many Mac program menus, Shift is displayed by the symbol 9781118023761-ma013.eps .
• The Option key is used in keyboard shortcuts. In Mac OS X and in many Mac program menus, you see the symbol 9781118023761-ma004.eps used. Note that Mac keyboards often add the label Alt to the Option key; this is for the convenience of Windows users, because the Option key functions as the Windows Alt key when you are running Windows on a Mac.
• The Control key is used infrequently for shortcuts; its main use is to open contextual menus when combined with a mouse click. In Mac OS X and in many Mac programs, you see the symbol 9781118023761-ma005.eps used.
• The Tab key is used both to move within fields in panes and dialog boxes and to insert the tab character in text. Mac OS X and many Mac programs indicate it in menus with the symbol 9781118023761-ma006.eps .
• The Esc key is typically used to close a dialog box or pane and cancel any settings you entered in it. It's also used in a few keyboard shortcuts. Mac OS X and many Mac programs use the symbol 9781118023761-ma007.eps in their menus to indicate it.
• The Return key is used to apply a dialog box's settings and close the dialog box (equivalent to clicking OK or Done), as well as to insert a hard paragraph return in text. In Mac OS X and many Mac programs, it is indicated in menus by the symbol 9781118023761-ma010.eps .
• The Delete key deletes text, one character at a time, to the left of the text-insertion point. In Mac OS X and many Mac programs, the Delete key is indicated in menus by the symbol 9781118023761-ma008.eps .
• The Eject key ejects a CD or DVD from your Mac's optical drive. In Mac OS X and many Mac programs, it is indicated in menus by the symbol 9781118023761-ma012.eps .
• Macs with an extended keyboard—one with a numeric keypad—have a second Delete key (below Help or Fn and next to End) that deletes text to the right of the text-insertion pointer. Called Forward Delete, newer Mac keys label it Delete 9781118023761-ma009.eps . In Mac OS X and many Mac programs, the Forward Delete key is indicated in menus by the symbol 9781118023761-ma009.eps . On a regular Mac keyboard, use Fn+Delete to get the Forward Delete action.
• On some MacBook keyboards and on extended keyboards' numeric keypad is a key labeled Enter that sometimes works like the regular Return, but not always. (I refer to Enter as keypad Enter in this book.) In Mac OS X and many Mac programs, it is indicated in menus by the symbol 9781118023761-ma011.eps . On regular Mac keyboards, Fn+Return acts as Enter.
• Also on extended keyboards, Home either moves to the beginning of the line or the beginning of the document, depending on how the application interprets it, End moves either to the end of a line or end of the document, Page Up moves up one screen, Page Down moves down one screen, Help opens the Mac OS X help system (see Chapter 7), and Clear clears the entries in a calculator-style application and sometimes acts as Num Lock in other applications. Note that not all extended keyboards have all these keys.
• The Fn key is used as a modifier key, where you hold it down while pressing one or more other keys to access a specific function. For example, Fn+← acts as an extended keyboard's Home key, Fn+→ as the End key, Fn+↑ as the Page Up key, and Fn+↓ as the Page Down key.
• The F keys are rarely used in Mac OS X for their original function: compatibility with Unix and mainframe special functions. Instead, most are now used as shortcuts for controlling the Mac hardware, such as to increase screen brightness (F2) or pause a video (F8), and some are used to invoke Mac OS X interface items (such as F3 to launch Exposé and F4 to launch the Dashboard). Note that newer Macs have icons above the F keys that indicate what hardware and Mac OS X interface items they invoke—and note that what specific F keys do varies across different Mac models. Also note that you may need to press Fn when using such F keys, depending on the settings in the Keyboard system preference (see Chapter 28).
If you're supposed to press several keys at the same time, I indicate that by placing plus signs (+) between them. Thus, Shift+Ô+A means press and hold the Shift and Ô keys, and then press A. After you've pressed A, let go of all three keys. (You don't need to hold down the last character in the sequence.)
I also use the plus sign (+) to join keys to mouse movements. For example, Option+drag means to press and hold the Option key while dragging the mouse on the Mac.
Working with the mouse
Apple was the first company to use the mouse in a commercially available computer, and it fundamentally changed how people interacted with computers. The mouse is a pointing device, so it becomes an extension of your hand and lets you virtually grab, move, and press on objects.
On the Mac OS X screen, you see the mouse's current position via the pointer icon, which is usually a black arrowhead but whose shape can change based on the current activity (to help you understand what activity is occurring). For example, when working in text, it appears as the I-beam text cursor icon.
To grab
an item with the mouse, you click (press) and hold the mouse button and then move the mouse to move the item. Let go of the button to drop
the item in its new location. (An item could be an icon or a scroll bar, for example.)
Some items need to be selected before they can be moved: For example, for text, you click and hold the mouse button, then drag to the end of your text selection, and finally let go of the mouse button. The text remains selected, and you hover the mouse over it, then click and hold, and then drag (I call that whole operation simply dragging) to move the text block. The same principle applies to selecting multiple icons, except that you draw a rectangle (called a marquee) around the items you want to select using the same click, hold, drag, and release action.
When using the mouse, you should know these conventions for click actions:
• Click: Most Mac mice have only one button, but some have two or more; the Mighty Mouse and Magic Mouse that Apple has included with some Macs for the last several years appear to have one button but can in fact detect which side of the mouse you are pressing, so in effect they have two buttons. If you have a multi-button mouse, quickly press and release the leftmost mouse button (or the left side of the Mighty Mouse or Magic Mouse) once when I say to click the mouse. (If your mouse has only one button—you guessed it—just press and release the button you have.)
• Double-click: When I say to double-click, quickly press and release the leftmost mouse button twice; if your mouse has only one button, just press and release twice the button you have. On some multi-button mice, one of the buttons can function as a double-click (you click it once, the mouse clicks twice); if your mouse has this feature, use it because it saves strain on your hand.
• Right-click: If your mouse has at least two buttons, right-clicking means clicking the right mouse button. On a one-button mouse, hold the Control key when clicking the mouse button to achieve the right-click effect. (Right-clicking is usually used to open contextual menus, as explained later in this chapter.)
Working with the touchpad
Laptops—both Apple's and Windows-based ones—have long had a device called a trackpad that replaces the mouse, converting finger movements on its surface to the equivalent mouse movements. These trackpads also have buttons that equate to mouse buttons.
But in 2007, Apple released the first iPhone, a device that took touch technology to a whole new level, adding support for more complex gestures than just moving a pointer across the screen. And in 2008, it brought that touch technology to the MacBook laptop line in the form of a touchpad, a more sophisticated version of a trackpad. Since then, Apple has increased the sophistication of touch gestures—movements and taps—that the touchpads support in each successive generation of MacBook, as well as introducing the Magic Trackpad and Magic Mouse, two wireless input devices that provide touchpad surfaces to all Macs, not just MacBooks (and they let MacBook users whose MacBook cases are closed—such as when docked—use the touch capabilities).
With sophisticated touch devices now available for all Macs, Mac OS X Lion has made the use of touch a fundamental part of some Finder operations, not just an alternative to the traditional use of a mouse. It's especially used in the new Launchpad (see Chapter 14) and with the new Mission Control feature (covered later in this chapter).
Note
Throughout this book, if I describe a mouse action, you also can use the equivalent touchpad action, unless I say otherwise.
Mac OS X Lion supports a large number of gestures, but not all touchpads support them all. All MacBooks before 2008, as well as the Magic Mouse, support only one- and two-finger gestures, while MacBooks produced in 2008 and later, as well as the Magic Trackpad, support one-, two-, three-, and four-finger gestures. The Trackpad system preference (see Chapter 28), shown in Figure 2.2, shows only the gestures supported by your specific touchpad. The figure also shows the gesture preferences in the Mouse system preference (also see Chapter 28) for the Magic Mouse.
FIGURE 2.2
Left: The Trackpad system preference is a great way to become familiar with the gesture options available on your Mac. Right: The Mouse system preference also lets you manage gesture settings on the touch-enabled Magic Mouse.
9781118023761-fg0202.epsThese gestures are supported:
• Tap: This is the equivalent of mouse-clicking, using your finger to lightly tap the touchpad.
• Double-tap: Double-tap on the touchpad with one finger for the equivalent a mouse's double-click.
• Click: This is also a form of mouse-clicking, though it's intended for actions where a regular tap could have a different meaning. For example, you click when starting to drag-select via a touchpad rather than tap when starting. On a Magic Trackpad and on newer MacBooks, a click differs from a tap in that the touchpad surface actually depresses in a click. On touch surfaces that don't physically depress, there's usually a trackpad button that you click (essentially, a separate mouse button for the touchpad).
• Right-click (secondary click): Tap and hold two fingers on the touchpad, and then tap with a second finger. You also can set the touchpad to translate a single tap in a specific location (by default, the lower-right corner) as a right-click if you change the Secondary Click pop-up menu's option in the Trackpad system preference.
• Drag: Click the trackpad button (or the touchpad itself if it can depress), hold with one finger, and then drag the item with a second finger. You also can enable a gesture whereby dragging three fingers moves the objects (no clicking required).
• Drag-select: Click outside an item on the desktop or Finder window, hold with one finger, and then drag the second finger to create a selection marquee (a rectangle whose first corner is where you tapped and whose diagonally opposite corner is your second finger's location).
• Scroll: Drag two fingers simultaneously in the direction you want to scroll the screen or window.
Note
The direction of the swipe may not be intuitive to you: By default, Mac OS X Lion moves the content (such as the text in a text editor, so swiping down moves the text down in the current window, in effect moving you to the top of the text) in the direction you swipe—just like on an iPhone or iPad. But with a mouse's scroll wheel, we've been trained that scrolling moves the scroll bar (so moving the scroll bar down moves the text up as you move toward the bottom of the screen). Mac OS X Lion lets you have touchpad scrolling work like a mouse's scroll wheel rather than like on an iPhone or iPad. In the Scroll & Zoom pane of the Trackpad system preference (and in the Mouse system preference for a Magic Mouse), select the option labeled Scroll with Finger Direction, to have the scroll mimic the behavior of a mouse's scroll wheel instead of the behavior of an iPad or iPhone.
• Swipe: This means to move one finger across the touchpad in one direction, such as for scrolling.
• Pinch: This means to put two fingers apart on the touchpad and then move them together, to zoom out the view (include more of the content on the screen).
• Expand: This means to put two fingers together on the touchpad and then move them apart to zoom in the view (magnify part of the content on the screen).
• Rotate: Place two fingers (or your index finger and thumb) on the touchpad and rotate clockwise or counterclockwise to rotate the active object.
• Two-finger double-tap: Double-tap two fingers on an object or screen area to smart zoom
into that area.
• Zoom screen: Press and hold Control, and then place two fingers on the touchpad and scroll up to zoom in or down to zoom out. If you move the mouse around the screen at the same time, the zoom's center follows the mouse. (You can change the modifier key used from Control to Option or Ô in the Trackpad system preference by clicking the Options button next to the Screen Zoom option to open a settings sheet and select the desired key via the Zoom While Holding pop-up menu.)
• Three-finger double-tap: Double-tap three fingers on text or a text selection to have Mac OS X Lion look up the text in its dictionary (the same dictionary terms that you can access as the Dictionary application, as described in Chapter 14).
• Two-finger scroll: This gesture by default moves you through pages as you swipe to the left (back or up) or to the right (forward or down). You also can set this action to the two-finger left and right swipe gestures or to the two- or three-finger swipe (any direction) gesture.
• Four-finger swipe up: This gesture by default toggles the Mission Control view (explained later in this chapter) and the normal Finder view. It is configurable to use three fingers instead.
• Four-finger swipe down: This gesture by default toggles the App Exposé view (explained later in this chapter) and the normal Finder view. It is configurable to use three fingers instead.
• Four-finger pinch and spread: These gestures (you move three fingers in one direction and the thumb in the other) switch between showing the Launchpad and the desktop, respectively.
As with mouse commands, some gestures require or behave differently when paired with holding down modifier keys on the keyboard. For example, Control+tapping on a touchpad has the same effect as Control+clicking on a mouse: right-clicking.
New Feature
Mac OS X Lion adds the four-finger pinch and spread gestures for viewing the Launchpad and desktop, the three-finger double-tap gesture for looking up text, and the two-finger double-tap for smart zooming, and Lion redefines the four-finger and three-finger swipe gestures to support the new Mission Control feature.
Understanding the Desktop
Apple popularized a graphical user interface (GUI) with a desktop metaphor with its famous Macintosh line, introduced in 1984. As Microsoft followed suit with Windows, it made the desktop metaphor common parlance throughout the world.
The desktop metaphor is the concept of the screen on the monitor acting as a visual representation of your physical desk. In this sense, the desktop contains folders (which are virtual representations of cardboard folders or drawers), documents (which are virtual pieces of paper), a trash can to dispose of items, and other visual icons designed to imitate real-life objects.
Despite being based on a commonplace metaphor, the desktop used in Mac OS X has many features and functions that may not be immediately apparent.
In essence, the desktop is the background on the screen—the expanse of space that sits behind the Dock and below the menu bar, or its canvas. By default, every version of Mac OS X has featured a different background image signifying which version of Mac OS X is running.
New Feature
Mac OS X Lion uses a photo of a galaxy as its default desktop background image, not the stellar auroras of Mac OS X Leopard and Snow Leopard. The selection of background images included with Mac OS X Lion (in the Desktop & Screen Saver system preference, described in Chapter 28) differs from previous versions of Mac OS X, with several new African animal scenes (including one of a lion) and several new nature scenes. Among the removed images are the emblematic space images of Mac OS X Leopard and Snow Leopard.
But the arrangement of the default disk icons has not changed: The startup disk appears at the upper right of the desktop, and any additional disks' icons appear below the startup disk's icon. (If you don't see the disk icons, choose Finder⇒Preferences or press Ô+, [comma] to open the Preferences dialog box. Select the Hard Disks option and the External Disks option in the General pane; click or tap the General icon if that pane is not displayed.)
You must understand that although the desktop is the space on the screen, it is also a folder inside your Home folder, located in /Users/username/Desktop. Whatever is in that folder appears on the desktop when that user is logged in. And whatever that user puts on the desktop is actually placed in that folder. Because different users have different Home folders, the desktop is individual to each user. (I explain the folder structure of Mac OS X in Chapter 4.)
Note
Although the icons of disks appear on the desktop, they do not appear inside the /Users/username/Desktop folder, not even as aliases. These icons appear on the desktop purely because it is convenient for Mac OS X to place them there. (They are also accessible via the Finder's Sidebar, as explained in Chapter 3.) The fact that disk icons appear on the desktop, but are not in the /Users/username/Desktop folder, is an exception to Mac OS X's rule that all folders display the items they contain.
The arrangement of icons for disks, folders, and files—all of which can be placed on the desktop by saving them there from applications or dragging them there from other locations—is arbitrary. You can drag icons anywhere you want on the desktop, arranging it as you prefer (even as a mess of items!).
You also can customize the appearance of the desktop using the Desktop & Screen Saver system preference to change the desktop's background image (see Chapter 28) and by using the Finder's View Options controls over how icons display in Finder windows and on the desktop (see Chapter 3).
Working with Menus
Like most operating systems, Mac OS X uses menus to give you lists of commands and functions that can be used by programs and the operating system as a whole. Menus take up considerable space on the screen, so they tend to be hidden except for a single label (a word, such as File or Edit, or an icon); clicking this label (which Apple calls a title) brings up a menu of commands, such as New Document, Open, and Save.
In Mac OS X, a single menu appears at the top of the screen called the menu bar. Some of the titles for the items in the menu bar change, based on which application is active at the time. Some menu labels, such as 9781118023761-ma001.eps , File, Edit, Window, and Help, almost always appear because Apple insists that applications use a consistent interface so users can easily move among them.
Note
Apple uses the term drop-down menu to refer to the menus in the menu bar and the term pop-up menu to refer to menus available within applications and windows.
Applications and windows also can have menus, called pop-up menus, which are accessed by clicking titles, icons, or buttons (both text and icon). Pop-up menus can appear in a variety of areas within an application or window, including in sub-windows, side panes, dialog boxes, and control panels. Most applications make their main menus available in the menu bar, but they may make additional menu options available through a control ribbon at the top or side of the application window. Finder windows also display their window-specific menus at the top of the window, leaving the universal Finder menu controls in the menu bar.
A third type of menu in Mac OS X is the contextual menu. You don't see contextual menus until you hover over an item and then either right-click it with a multi-button mouse or hold down the Control key and click the primary (or only) mouse button (called Control+click). Contextual menus also may be accessed via touchpads using the taps and gestures that equate to the mouse buttons (described later in this chapter). Contextual menus are so named because their contents change according to the context (area or item) that you right-click or Control+click.
Note
Apple's recent mice have one physical button that detects which side you press, interpreting a press on the right side as a right-click and a tap on the left side as a regular (primary) mouse click.
Working with drop-down menus
To access an option in a drop-down menu, you typically use the mouse or touchpad to control the pointer and choose one of the options. You can choose menu options one of two ways:
• Click, move, and click: Move the pointer over the menu title, and click the mouse button or tap the touchpad to reveal the list of menu options. Then move the pointer down the list to highlight the menu option you are interested in. Click the menu option to activate it. The highlighted option flashes to indicate that it has been chosen, and Mac OS X executes whatever the menu option is designed to do in the application or window, such as execute a task or open a dialog box. (If you click a menu title and decide that you do not want to select any option, simply click anywhere on the screen other than on a menu option to close the menu and continue working.)
• Click and hold, move, and release: Move the pointer over the menu title, and click and hold the mouse button or tap and hold the touchpad. While holding the mouse button or your finger down, move to the menu option you want to select and, with the item highlighted, release the mouse button or your finger. The menu option flashes, and the menu option executes whatever it is designed to do. (Note that when you navigate submenus, the pointer must stay within the bounds of the submenu; if it leaves its area, the submenu closes automatically.)
The method you use is largely a case of personal preference.
Some menu options also may expand to reveal further options, as Figure 2.3 shows. These are called submenus; a submenu is indicated by a small black triangle to the right of the menu option. Moving the pointer to one of these menu options makes the submenu expand to the right and present further options. (In some applications and windows, the submenu may expand to the left.) Moving the pointer into the submenu enables you to select these further options. It is rare for a submenu to contain further submenu options, known as nested submenus, although some complex programs do have nested submenus. (Adobe Dreamweaver CS5 is an example.)
In this book, I indicate a menu sequence using the ⇒ symbol between each option, such as Edit⇒Copy to indicate that you open the Edit menu and choose Copy, and Table⇒Insert⇒Row to indicate that you open the Table menu, choose the Insert option, and then choose the Row option from its submenu.
Using keyboard shortcuts for menu options
As you explore menu options, you'll see that certain ones have symbols and letters next to them. These are keyboard shortcuts, and they represent key combinations you can use instead of the mouse or touchpad to select menu options. Pressing Ô+O, for example, is commonly used to access the Open option from the File menu.
When you press a keyboard shortcut, the item on the menu bar flashes briefly to indicate that a menu option has been selected, although the menu itself does not expand to show the exact option being invoked.
Keyboard shortcuts can massively increase the speed at which you work and are well worth learning. You can discover many keyboard shortcuts by looking at the Keyboard Shortcuts pane of the Keyboard system preference. Here, you not only learn keyboard shortcuts, but you also can create your own, as Chapter 28 explains. Apple also has a comprehensive list of common keyboard shortcuts on its website (http://support.apple.com/kb/HT1343).
FIGURE 2.3
The Edit drop-down menu for the Pages application, showing a submenu for its Find menu option
9781118023761-fg0203.tifSome menu options may appear in a light gray text (a visual effect often referred to as grayed out), which indicates that the menu item is not available at the moment. Common examples are the Save and Print menu options that are grayed out in most applications if no document is open (because there is no document being worked on to save or print).
Recognizing menu symbols
Several symbols accompany menu items. Table 2.1 is a guide to the various symbols and their meanings.
/9781118023761-tb0201Touring the menu bar items
Although the menu bar changes according to which application is currently active, several menu options on the left side of the menu bar are common to all applications: Ú, File, Edit, Window, and Help. On the right side of the menu bar sit several icon menus that remain the same no matter which application is highlighted. The other menu options vary, based on what application is active.
The Ú (Apple) menu
At the far-left side of the menu bar sits the 9781118023761-ma001.eps menu (called the Apple menu). The options in this menu typically relate to the Mac as a whole and to system-wide options and commands. You can use the menu options here to get information about your Mac, perform software updates, and change system preferences; you also can log out, put your computer to sleep, or shut it down completely.
Because these 9781118023761-ma001.eps menu options remain the same no matter what application is open, let's look at them in depth. These options are available:
• About This Mac: Choosing this menu option brings up a window displaying information about your Mac. It informs you which version of Mac OS X you are running, what your processor speed is, the amount of memory (random access memory, or RAM) in your Mac, and what your startup disk is. There are also two buttons in this window. One is labeled More Info; clicking it opens the System Information utility that provides detailed information on all aspects of your computer. The other is labeled Software Update; clicking it opens the Software Update application and automatically connects to the Internet to look for updates to Mac OS X and the various Apple programs installed on your Mac.
Tip
Press and hold Option when the 9781118023761-ma001.eps menu displays to change the About This Mac menu option to System Information, which jumps straight to the System Information utility.
• Software Update: Choosing this menu option brings up the Software Update application.
• App Store: Choosing this menu option launches the Mac App Store, from which you can buy and download software for your Mac. You can sign in using your existing iTunes account and charge your purchases to the same credit card, or you can create a separate account.
• System Preferences: Choosing this menu option opens the System Preferences application, where you can adjust various aspects of the Mac OS X environment. The system preferences are explained in depth in Chapter 28.
• Dock: Choosing this menu option opens a submenu that provides controls for the Dock (explained later in this chapter). You can quickly adjust the magnification and position of the Dock from this menu option.
• Location: This menu option works with the Network system preference (which enables you to set different networking preferences for different environments). Typically, a laptop owner may connect a MacBook to his or her home network, as well as to a work network, and may have different settings depending on the environment. (Networking is explained in depth in Chapter 23.) The Location menu option offers a submenu for selecting different locations, so the appropriate network settings are activated for your current location. This menu option is present only if you have set multiple network locations using the Network system preference.
• Recent Items: This particularly handy menu option takes you to a submenu with three separate areas: Applications, Documents, and Servers. Each area contains the last 10 respective items that you have used on the Mac. So you get a list of the 10 recently used applications, documents you have opened, and server locations you have visited.
• Force Quit: This menu option brings up the Force Quit Applications dialog box, which shows all running applications on the Mac, and is where you force unruly applications to quit. It is rare that you will need to use the Force Quit menu option, but it can prevent you from having to restart your computer. The Force Quit
