Even if you’ve set your Dock preferences not to animate when you click them, some applications insist on bouncing to get your attention. This brief tutorial will show you how to disable that behavior.

If you open your System Preferences and select Dock, you can disable the animation (bouncing) that happens when you click an icon in your Dock. Just remove the check from the box labeled Animate opening applications.

But sometimes applications are set to “bounce” when they want your attention.

To disable this feature, open a Terminal (Applications -> Utilities -> Terminal) and enter the following commands:

defaults write com.apple.dock no-bouncing -bool TRUE

and then

killall Dock

Your Dock will close, then open again. From now on, none of your Dock icons will bounce – ever.

If at any point you want to reverse this, just enter the command:

defaults write com.apple.dock no-bouncing -bool FALSE

and then

killall Dock
