I have a 'workaround':
- Quit iTunes
- Locate iTunes.app in Finder (In Finder: Menu › Go › Applications...)
- Ctrl-click on the iTunes.app-file and select 'Compress "iTunes.app"' (for backup)
- Ctrl-click on the iTunes.app-file and select 'Show Package Contents'
- Locate the file 'Info.plist' inside the folder 'Contents'
- Ctrl-click 'Info-plist' and select 'Open with..' and select 'TextEdit' (or your favourite text-editor. Not Word tho.)
Near the bottom of the file locate the following segment:
<key>CFBundleIdentifier</key> <string>com.apple.iTunes</string>
Change the last 's' in the word 'iTunes' to 'z', like so:
<key>CFBundleIdentifier</key> <string>com.apple.iTunez</string>
Save the file
- IMPORTANT: Drag the file 'iTunes.app' out of the Applications-folder and on to the Desktop
- Drag the file 'iTunes.app' back into the Applications folder
- (You should probably disable the iTunesHelper. This can be done by going to System Preferences › Accounts › (Your account) › Login Items and remove the 'iTunesHelper'.)
- Log out and log in
I hope this works. It works for me!
