When Apple released iTunes 9, they finally changed the behavior of the green zoom button to match most other apps in OS X. Then in iTunes 9.0.1 – and almost certainly due to customer feedback (it really annoyed me to have to learn yet another keyboard shortcut to switch back to the mini-player) – they changed it back. Clicking the green zoom button once again ‘minimizes’ iTunes to the mini-player.
If you actually liked the change (having the green zoom button resize the iTunes window rather than changing to the mini-player), open Terminal (Applications -> Utilities -> Terminal) and enter the command:
defaults write com.apple.iTunes zoom-to-window -bool YES
Now you’ll have the green zoom button behavior that iTunes 9.0 introduced. If you change your mind yet again, replace YES in the above command to NO.
This was already fixed with the last iTunes update.
Vitaliy,
I probably didn’t make the wording clear enough, I’ll update this post. The point of this tutorial is to make iTunes behave like it did in 9.0 – the way most people DIDN’T like it. This tutorial shows you how to set iTunes to NOT go into “mini-player” mode when you click the green zoom button.
To get the “green button actually maximizes” behavior on demand you can just option-click on the green zoom button
