Auto-Hide, Shrink and Enlarge, Move, Magnification, and Effects
There are several ways to personalize the size and feel of the Dock:
You can use Auto-Hide to remove the display of the Dock and then bring it back whenever you need it.
You can shrink or enlarge the Dock.
You can move the Dock to another area of the screen.
You can change how the Dock’s icons are magnified when the pointer is moved over them.
You can even configure what effects are used when applications are minimized.
All of these options are configured from the same area of your Mac’s interface, so let’s take a look at that now:
1. Open Applications>System Preferences>Dock.
2. To change the Dock’s size, move the Dock Size slider. You’ll see the changes immediately.
Tip: If you just want to resize the Dock, you can click and drag the dividing line on the Dock itself up and down. This saves opening System Preferences.
3. To change how icons are magnified when the mouse is used to hover over them, check Magnification and move the slider to the right or left to configure it. Use your mouse to see the changes immediately.
4. To change the Dock’s position on the screen, select Left, Bottom, or Right.
5. To change the effect used when applications are minimized to the Dock, select Scale Effect or Genie Effect.
Tip: When a program is minimized, it disappears in a “genie in a bottle” fashion. If you’d like programs to go away faster, switch from Genie Effect to Scale Effect.
6. To turn off animations when programs are opened, uncheck Animate Opening Animations. (The less work your Mac has to do to perform a task, the faster it will do it.)
7. To hide and show the Dock automatically when the pointer is moved over the area of the screen where the Dock usually resides, check Automatically Hide And Show The Dock. (To manually show the Dock only when necessary, leave this unchecked and use Command+Option+D as needed.)
8. Close this window.
Tip: If you feel as if the Dock is always in the way, or if it ever prevents you from viewing a necessary part of a program’s interface, such as an information line that runs across the bottom of the screen or the last part of a Web page, you’ll want to hide the Dock.
