|Tip 176||Calm a Bouncing Dock Icon|
Some apps bounce their Dock icons when they want to tell you something, such as when a task has completed. Some apps bounce their icons for a short while, while others will keep bouncing the icon until you do something about it. This can be annoying if you’re busy doing something else.
Temporarily Calming a Dock Icon
While clicking the Dock icon to activate the app is one solution, another is simply to move your mouse cursor over the icon. It will instantly stop bouncing, and you can then return to the task at hand.
Deactivating Dock Bouncing
If you finding it irritating, you can turn off the Dock icon bouncing entirely, although bear in mind this means you won’t know when an app requires your attention.
The Dock bounces when one of two events occur: when an app launches and if an app requires attention. The former can be turned off by opening System Preferences (Apple→System Preferences) and then clicking the Dock icon, before removing the check from the Animate Opening Applications box.
The latter can be switched off via a hidden setting. Open a Terminal window (open Finder, select the Applications list, and then in the list of applications double-click Terminal within the Utilities folder), and type the following:
defaults write com.apple.dock no-bouncing -bool TRUE;killall Dock
The changes will take effect straightaway.
To reactivate Dock icon bouncing, repeat the previous steps with System Preferences, open a Terminal window, and type the following:
defaults delete com.apple.dock no-bouncing
