How to Launch and Quit Applications with Mavericks on Your MacBook

By Mark L. Chambers

Now it’s time to pair your newly found trackpad acumen with the Mavericks Finder window on your MacBook. Follow along with this simple exercise. Move the cursor over the iTunes icon in the Dock. (This icon looks like an audio CD with a musical note on it.) Then tap the trackpad once. Whoosh! Mavericks launches (or starts, or runs) the iTunes application, and you see a window.

If an application icon is already selected you can simply press ⌘+O to launch it. The same key shortcut works with documents, too.

Besides the Dock, you have several other ways to launch an application or open a document in Mavericks:

  • From the Apple menu: You can launch a number of applications from anywhere in Mavericks using the Apple menu:

    • System Preferences: Change all sorts of settings, such as your display background and how icons appear.

    • Software Update: Use the Internet to see whether update patches are available for your Apple software.

    • App Store: Launch the OS X App Store and display software that you can download for your laptop. (Most are commercial applications that you have to pay for, but many great free applications are available as well.)

  • From the Launchpad: Arrange all your application icons in a full-screen display. (The Launchpad icon in the Dock is the second one from the left, bearing a rocket.) If you have more than one screen (or page) worth of applications, press the arrow keys to move between Launchpad pages. Using the trackpad, swipe two fingers to the left or right.

    To launch an application, just click the icon. (If you’re the proud owner of an iPhone, iPad, or iPod touch, the Launchpad is familiar, because it corresponds directly to the Home screen on those devices.)

  • From the Desktop: If you have a document you created or an application icon on your Desktop, you can launch or open it from the Desktop by double-clicking that icon (tapping the trackpad twice with one finger in rapid succession when the cursor is on top of the icon).

    Double-clicking a device or network connection on your Desktop opens the contents in a Finder window. This method works for CDs and DVDs you’ve loaded, as well as external drives and USB flash drives. Just double-click ’em to open them and display their contents in a Finder window.

    Applications and documents typically launch from a CD, a DVD, or an external drive just like they launch from your internal drive (the one that’s typically named Macintosh HD). So you don’t have to copy stuff from the external drive just to use it. Note, however, that running an application directly from your optical or external drive usually causes the application to run significantly slower.

  • From the Recent Items selection: When you click the Apple menu and hover the cursor over the Recent Items menu item, the Finder displays all the applications and documents you used over the past few computing sessions. Click an item in this list to launch or open it.

  • From the login items list: Login items are applications that Mavericks launches automatically each time you log in to your user account.

  • From the Finder window: You can also double-click an icon within the confines of a Finder window to open it (for documents), launch it (for applications), or display the contents (for a folder).

The OS X Quick Look feature can display the contents of just about any document or file — but without actually opening the corresponding application! Sweet. To use Quick Look from a Finder window, click a file to select it, and then press the spacebar.

After you finish using an application, you can quit that application to close its window and return to the Desktop. Here are a number of different ways to quit an application:

  • Press ⌘+Q. This keyboard shortcut quits virtually every Macintosh application. Just make sure that the application you want to quit is currently active first (the application name should appear immediately to the right of the Apple menu).

  • Choose the Quit command from the application’s menu. To display the Quit command, click the application’s named menu from the menu bar. This menu is always to the immediate right of the Apple menu. For example, Safari displays a Safari menu, and that same spot in the menu bar is taken up by Calendar when Calendar is the active application.

  • Choose Quit from the Dock. You can right-click an application’s icon in the Dock and then choose Quit from the menu that appears.

    A running application displays a small blue dot under its icon in the Dock.

  • Click the Close button in the application window. Some applications quit entirely when you close their window, such as the System Preferences window or the Apple DVD Player. Other applications might continue running without any window, such as Safari or iTunes; to close these applications, you have to use another method in this list.

  • Choose Force Quit from the Apple menu. This is a last-resort measure! Use this method only if an application has frozen and you can’t use another method in this list to quit. Force-quitting an application doesn’t save any changes to any open documents in that application!
