Mac OS X Tip – Enable iTunes Track Notifications In The Dock
If your Mac is running Lion, there is a hidden feature that when enabled, will give you iTunes ‘Now Playing’ notifications in the dock.
With this notification, when a new song starts, a pop-up will appear in the dock, letting you know the artist and song title – After a few seconds it slowly fades away.
To enable this nice feature, you will need to open Terminal, which is located in Applications/Utilities (you can also search for Terminal in Spotlight and just select it from the drop-down).
Once you are in Terminal, paste in the following command: defaults write com.apple.dock itunes-notifications -bool YES and hit return.
Now you will need to restart the Dock for the notifications to work – To do this, paste the command: killall Dock in Terminal and tap return.
If at any point you want to disable the feature, follow the above steps, but replace YES with NO.
