Hide and Show the Dock in Mac OS X
The Dock is one of those staple features of Mac OS X, containing all running apps and also serving as a quick launch bar for opening applications and managing multitasking. The Dock is popular and intuitive enough for it to be a core user interface element beyond the Mac, included as a major component in iOS and other OS’s too.
A simple trick to improve Dock functionality is hide it when the Dock is not actively in use. When the automatically hide feature is on, the Dock only shows itself when a cursor is placed over the region of the Mac screen where the Dock is displayed. This is easy to configure, either with a keyboard shortcut or by visiting the OS X system preference settings, let’s get to it cover both.
Hide and Show the Dock with a Keyboard Shortcut
If you hit Command+Option+D it will automatically hide or show the Dock in OS X. If you choose to hide it this way, it will reappear back if you hover over the region that you have your Dock placed with the mouse cursor.
The keyboard shortcut effectively toggles the auto-hide feature on or off without going into the System Preferences, which we’ll cover next:
Automatically Hide the Dock When Not in Use
You can set the Dock to automatically hide itself when it’s not being used by either hitting the key shortcut as mentioned above, or by enabling the option in the Dock Preference panel. For most Mac users, the System Preferences method is preferred:
- Open System Preferences from the Apple menu and choose “Dock”
- Check the box for “Automatically hide and show the Dock” by clicking the checkbox next to it
The setting looks very slightly different in past versions of OS X, mostly because there are less options available to customize the Dock experience in general:
When this box is checked, the dock will automatically hide itself when it’s not in use. To make the Dock appear, simply hover the mouse cursor over the bottom of the screen.
This is an underused but great feature that preserves screen real estate, making it particularly valuable for Mac users with smaller displays, like the MacBook Air and MacBook Pro.
Why Auto-Hide the Dock?
I use the Dock constantly, combined with Spotlight it’s how I launch applications on my Mac. However, I find that having the Dock automatically hide itself when not in use saves me a fair amount of screen real estate on my MacBook Pro 13″ and this is particularly valuable with maximized applications and web browsing.
Modern versions of OS X will see the Dock automatically hide itself by default when entering into the full screen app mode.
New to the Mac and not sure about the Dock yet? Think of it similar to the task bar for Windows, though modern versions have used variations of the Dock theme and incorporated into Vista, Win 7, and Windows 8. Similarly, Dock-like functionality is included Android and Ubuntu too for that matter, it’s just one of the most convenient ways to quickly launch apps, whatever you’re using.
