How can I downgrade iTunes 11 to 10.7 in Mountain Lion?
12/8/12: I have updated my How To on my blog with a new method to go from iTunes 11 to 10.7 using Pacifist. It does not require any backup, just a copy of Pacifist, the iTunes 10.7.dmg &amp; a little time. Click on the link below.

I've created a How To on my blog showing how to downgrade from iTunes 11 to iTunes 10.7. It also includes a link to download a copy of iTunes 10.7 if you need it.

I'll post it here too.

1) Open Terminal and run:

 sudo rm -rf /Applications/iTunes.app


This will delete the iTunes 11 application.

2) If your Music Library is in its default place, also in the terminal:

  open ~/Music/iTunes


3) Using Time Machine restore the following files:


Album Artwork   &lt;– Folder
iTunes Library
iTunes Library Extras.itdb
iTunes Library Genius.itdb
iTunes Library.xml
iTunes Library.itl
iTunes Music Library.xml
Previous iTunes Libraries  &lt;– Folder


No need to replace your iTunes Music Folder. You may not need to replace all these files but it can’t hurt.

4) Back in the terminal:

open /System/Library/PrivateFrameworks


Use Time Machine again to restore the following files:


AirTrafficHost.framework
CoreFP.framework
DeviceLink.framework
iTunesAccess.framework
MobileDevice.framework


5) Download iTunes 10.7

6) Install iTunes 10.7.

I rebooted for good measure, but it’s probably not necessary.

You may be prompted the first time you start up iTunes 10.7 for your password. Enter it. You should now be able to do all the things you need, including syncing your iDevices, without the nasty iTunes -42408 error many people have been getting before this method.

Enjoy iTunes 10.7!
