Display Music Track And Artist Information In The Dock With This Secret iTunes Terminal Command [Mac OS X]

There's a hidden setting for the Dock that will show pop-up notifications of which iTunes track is playing, a little like Growl.

First, quit iTunes if it's open, then open a Terminal window and type the following:

• defaults write com.apple.dock itunes-notifications -bool TRUE;killall Dock

Then start iTunes and try playing a track. Neat, eh? The pop-up fades away after a few seconds. To add the iTunes icon to the pop-up window, type the following into a Terminal window:

• defaults write com.apple.dock notification-always-show-image -bool TRUE;killall Dock

To deactivate the pop-up at a later date, quit iTunes again, then open a Terminal window and type the following two lines:

• defaults delete com.apple.dock itunes-notifications
• defaults delete com.apple.dock notification-always-show-image;killall Dock
