Show Only Currently Active Apps in the Mac OS X Dock
Here’s a great trick if you prefer a minimalist Mac OS X desktop and Dock: set the Dock to only display currently active apps. Launch the Terminal and enter the following command:
defaults write com.apple.dock static-only -bool TRUE
Now you have to kill the Dock for changes to take effect:
If you use the Dock as an app launcher, this probably won’t be that useful for you. I almost always use Spotlight to launch apps and have my Dock automatically hide, so I’m going to try this out for a while and see how well it works in my day to day workflow.
If you want to revert back to the default Dock behavior, use this command:
defaults write com.apple.dock static-only -bool FALSE
Don’t forget to kill the Dock again for the changes to take effect.
Note: if you try out this tip and don’t like it, you won’t lose your previous Dock icons or arrangement, just use the FALSE command and everything will be back to normal.
