Roaming the internet as I usually do, I oftentimes stumble upon some gems for customizing my Mac even more. Here’s a cool one that I found recently, paraphrased here for posterity. It looks like it’s new to OS X Lion.
There’s a hidden setting for the Dock that will show Growl-like popup notifications for the current iTunes track.
Just quit iTunes, and then run this in a Terminal window:
defaults write com.apple.dock itunes-notifications -bool TRUE;killall Dock
When you open iTunes and start playing a track, this little info popup appears above the iTunes dock icon. It fades away after a couple seconds. I’d recommend adding the iTunes icon to the notification, just to make it look nicer:
defaults write com.apple.dock notification-always-show-image -bool TRUE;killall Dock
To undo these changes:
defaults delete com.apple.dock itunes-notifications
defaults delete com.apple.dock notification-always-show-image;killall Dock
These prefs are hidden for a reason, and they might be removed in a future OS update. But for now, they look cool.
