I want to resize iTunes, but can't. What do I do now?

Connect it again to an external screen or delete the Users > You > Library > Preferences > com.apple.iTunes.plist file.
If that does not help, here is another topic talking about that issue and involving Terminal.

Try option-click the green button on the top left. Should be a faster fix.

That worked. Weird that it would get locked like that. Thanks!

No problem. Most people don't know of the option-click trick, I only recently discovered it on a random blog post that I somehow happened to read.

i have tried everything ?

i have tried option clicking green button,

i even tried all the nonsense with going into the terminal app that was posted in another thread.

nothing has worked? HELP! IT IS STILL UNDER THE LEVEL OF MY MAC WINDOW AND I CANT RESIZE ITUNES? ANYBODY GOT ANY IDEAS? !

soooo frustrating!

Have had another monitor connected? If so re-connect and resize it there.

Tried Window menu > Zoom yet? That should work well.

Try changing your display resolution in System Preferences to a lower resolution, click the green button to maximise it to that screen size, then change it back in System Preferences.
