Some of the properties of the Dock, the handy application launcher that usually resides at the bottom of your screen in OS X, can be modified to suit your preferences. Because you'll use the Dock often, you should set it up just the way you want it.
Location, Location, Location
No, I’m not imitating Steve Ballmer’s much-publicized developer's rant and dance. This is more about making the best use of your screen real estate, including the location of the Dock. The Dock's default location is the bottom of the screen, which works well for many individuals. But if you prefer, you can move the Dock to the left or right side of your screen.
- Click the ‘System Preferences’ icon in the Dock.
- Click the ‘Dock’ icon in the Personal section of the System Preferences window.
- Use the ‘Position on screen’ radio buttons to select a location for the Dock.
- Left positions the Dock on the left edge of your screen.
- Bottom positions the Dock along the bottom of your screen, the default location.
- Right positions the Dock on the right edge of your screen.
- Left positions the Dock on the left edge of your screen.
- Click the radio button of your choice, and then close the window.
Try all three locations, and see which one you like best. You can easily move the Dock again if you change your mind.
