I am running Mountain Lion on mid-2009 MacBook Pro. I used to see an animation of an app popping out of the Mac App Store and dropping into the dock. However, Apple changed the popup destination to Mission Control. Now, there is no such animation. When I click on "Install Now", the Mac App Store simply installs the application. There is no animation now of an app icon popping out and going into either the Dock or Mission Control. I used to love that animation, and would like to know if there is any way to get it back.
