Switching to the Mac: The Missing Manual, Yosemite Edition

Launchpad

The Launchpad app presents a dark background with evenly spaced icons that represent all your programs (Figure 4-4). You can open one with a single click.

Why did Apple feel the need to create yet another way to open programs?

First, because Launchpad fits right into the general theme of making the Mac look and work more like the iPad. Launchpad is a dead ringer for the Home screens of an iPad, iPhone, or iPod Touch.

Second, it’s a much less intimidating place for technophobes to learn to love than, say, the Applications folder.

And third, it’s a lot quicker to get to than the Applications folder. You can summon it instantly, using any of these methods:

• Put four fingers on your trackpad and pinch them together. The Launchpad appears instantly, no matter what program you were in; you don’t have to duck back into the Finder, navigate to the Applications folder, and so on.

• Press the Launchpad key. Recent Macs have a special Launchpad icon painted right on the F4 key ().

• Click its icon on the Dock. It’s the second one, resembling a rocket ().

• Press a keyboard shortcut of your choice. To set that up, choose →System Preferences→Keyboard. Click the Shortcuts tab, and then click Launchpad & Dock in the left-side list. On the right, make sure Show Launchpad is turned on—and then double-click in the blank space to the right of it and press the key combination you want.

• Move the cursor into one of the screen’s four corners. To set up these options, open →System Preferences→Mission Control. Click Hot Corners to choose a corner of the screen for Launchpad.

• Open it as you would any other program. It’s in your Applications folder.

One thing’s for sure: Sooner or later, you’ll wind up in Launchpad.

Figure 4-4. You can open Launchpad by clicking its Dock icon or by using a four-finger pinching gesture on your trackpad. Launchpad covers your entire main monitor, hiding everything else. Use the arrow keys to navigate a page; press ⌘-arrow to move between pages; press Option to make the icons start wiggling, ready for deletion.

Only three visual elements appear there:

• Icons. Each icon represents one of your programs. Apple’s programs are listed first, in alphabetical order: App Store, Automator, Calculator, and so on. Then come all your other programs, again in A-to-Z order. Click one to open that program.

  Sparkly animated twinkles surround any new app you’ve installed. (You can see them at lower left in Figure 4-4.)

  Note

  The only program icon that doesn’t appear in Launchpad…is Launchpad’s. That’s a good thing. You wouldn’t want to wind up in an infinite loop, would you?

• Search box. This box at the top of the screen lets you pluck one needle from your haystack of apps, no matter what page it’s on. You don’t have to click there first—just start typing when Launchpad is before you. With each letter you type, Launchpad hides everything but the matching app icons.

• Home page dots. As you install more and more programs, Launchpad makes room for them by creating additional screens. You can spread your new programs’ icons across an unlimited number of launch screens.

  The little white dots are your map. Each represents one Launchpad screen. If the third one is “lit up,” then you’re on the third screen.

  To move among the screens, press ⌘-arrow keys, or swipe horizontally with two fingers on the trackpad. (Magic Mouse: one finger.) Or tap directly on one of the little dots to jump to the corresponding screen.

Tip

To exit Launchpad without opening anything, click a blank spot, tap the Esc key, or—most fun of all—spread the same four fingers on the trackpad.

Redesigning the Launchpad Screens

If you use Launchpad a lot, it’s worth taking a moment to arrange its icons into logical categories or a sensible sequence. As it turns out, you can freely drag them into new spots; the other icons scoot aside to make room.

Tip

You can even drag an icon directly to the Dock to install it there for quicker access.

You can create additional screens, too. To do that, drag an icon to the right edge of the screen; keep your mouse button down. The first screen slides off to the left, leaving you on a new, blank one where you can deposit the icon.

You can organize your icons on these Home pages by category, frequency of use, color, or whatever tickles your fancy.

Folders

The Launchpad just wouldn’t be like the iPad if it didn’t also let you organize your apps into folders. Folders let you organize your apps, de-emphasize the ones you don’t use often, and restore order to that horribly flat, multipage display of icons.

To create a folder, drag one app’s icon on top of another. OS X puts both of them into a single new folder (Figure 4-5). If they’re the same kind of app, it even tries to figure out what category they both belong to—and names the new folder accordingly (“Music,” “Photos,” “Games,” or whatever). This new name is only a proposal; an editing window also appears so that you can type a custom name you prefer.

Figure 4-5. Open a folder by clicking once, or by pressing ⌘-. A special pane sprouts from the folder icon, revealing its contents; the rest of the screen goes away. Now you can drag the icons around inside it. You can also edit the folder’s name (click it first).

A folder can hold several rows’ worth of icons; if you add more apps than that, Launchpad adds additional “pages” that you scroll horizontally. (Little white dots indicate which page you’re on.)

Take an app out of a folder by dragging its icon anywhere else on the screen. The other icons scoot aside to make room. If you remove all but one app from a folder, the folder disappears.

Move a folder around by dragging, as you would any other icon.

Deleting App Store Programs

If you’ve downloaded some apps from the App Store, you’ll find a bonus feature here in Launchpad: They’re especially fun to delete.

Start by holding the mouse down on any icon until, after about a second, all the icons begin to—what’s the correct term?—wiggle. (If you have an iPhone, iPad, or iPod Touch, this should look familiar.)

Tip

You can also just press the Option key to trigger the wiggling. Sometimes, every second counts.

At this point, you may notice that some of them have sprouted little red X’s. Those are the ones you downloaded from the App Store.

To delete an App Store program you don’t need anymore, click that X to make it say bye-bye—instantly and for good. It doesn’t even have a layover in the Trash.

Note

You can’t delete non–App Store apps this way, so no X appears on those icons. Why not? Because this deletion method is so fast and permanent. It’s not much of a risk for App Store apps, because you can always download them again—but that would not be true of other apps.

UP TO SPEED: When Programs Are Actually Folders

OS X programs don’t seem to have 50,000 support files strewn across your hard drive. Most programs just sit there, naked and shivering, in your Applications folder—seemingly unaccompanied by libraries, dictionaries, foreign language components, and other support files and folders.

The question is: Where did all those support files go?

OS X features packages or bundles, which are folders that behave like single files. Every properly written OS X program looks like a single, double-clickable application icon. Yet to the Mac, it’s actually a folder that contains both the actual application icon and all its hidden support files. (Even documents can be packages, including iDVD project files, Keynote files, and some TextEdit documents.)

If you’d like to prove this to yourself, try this experiment. Choose Go→Applications. See the Calculator program? Right-click (or two-finger click) it. From the shortcut menu, choose Show Package Contents. You’re asking OS X to show you what’s inside the Calculator’s “application icon” folder.

The Calculator package window opens, revealing a Contents folder you’ve never seen before. If you open this folder, you’ll find a handful of strange-looking, Unix-named folders and files that are, behind the scenes, pieces of the Calculator program itself.

The application-as-folder trick is convenient for you, of course, because it means you’re generally free to move the application to a different window—or to uninstall the program by dragging this single icon to the Trash—without worrying that you’re leaving behind its entourage of support files. It’s also convenient for programmers, because they can update certain aspects of their applications just by replacing one of these component files, without having to rewrite the entire program.

You can even try out this programmery benefit for yourself. In the case of the Calculator and many other OS X programs, the Resources folder contains individual graphics files—PDF or TIFF files—that serve as the graphic elements you see when using the program. For example, the file lcd.tiff in the Calculator’s Resources folder contains the image of the calculator’s screen (where the numbers appear as you punch the calculator buttons).

Using a graphics program, you can change the background of this light-yellow calculator screen to, say, light blue. The next time you double-click Calculator—which you now realize is actually a folder behind the scenes—you’ll see your modified calculator design.

(P.S. There are still hundreds or thousands of support files that aren’t embedded within their programs’ icons. They’re sitting in your Library→Application Support folder, organized by software company.)
