I like my Terminal tricks, they are really handy. I don’t think I have mentioned this quick tip before. I have searched my database and no tips have turned up. This little Terminal tip will disable any icons in you dock from bouncing. If you find them annoying there is a simple command which enables you to turn the animation off.
As with any Terminal command open up this little app from Utilities. Type or copy and paste the following
defaults write com.apple.dock no-bouncing -bool TRUE
This will disable any dock bouncing. If you want to reverse the process replace TRUE in the command above with FALSE, and any bouncing icons should come bouncing back to see you.
