1: Just wiped drive and re-installed OS X Lion 10.7.3.
2: Upgrade iTunes from 10.5.2 to 10.5.3.
3: Restart, normally & fast.
4: Open iTunes.
5: Close iTunes.
6: Shutdown, and get the grey screen and spinning wheel...30min...1hr...2hr...I HAVE TO PRESS THE POWER BUTTON!!!
Why? Is it a bug in OS X Lion or iTunes 10.5.3?
How to sovle it?
(mid 2010 MacBook Pro 371, OS X 10.7.3)
MacBook Pro, Mac OS X (10.7.3)
Can anyone help me?
Download the full itunes 10.5.3 installer and reinstall.
Reboot in Safe Mode (hold down shift after chime), to rebuild caches, reboot again.
If problems persist check /Applications/Utilities/Console note the time of the hang and see if any errors occur at that time.
And most importantly: Don't post your off-topic issue off in other threads.
Just as an FYI, that gray screen is usually the result of a process that is running a loop / can't stop. That's my layman's interpretation of the actual process at least. I believe there were a few issues when Lion came out with that happening for a number of different programs. Search in the general Lion thread for a thread that might be related. FWIW it used to happen to me but doesn't anymore, and all I could suggest is as above (try a full install of iTunes, not via upgrades).
I have the exact same problem with my 2011 Mac mini, but I’ve had it since I bought it (I believe it came with 10.7.2). One question for you: my iTunes Library file is in ~/Music, but the actual song files are on a NAS. How is yours set up?
Oooh… looks like the issue might be with Parallels 7 and Kaspersky Antivirus. Do you have those installed?

Parallels 7 and Kaspersky Antivirus? No.
After using iTunes, my MacBook Pro doesn't shutdown normally.
