Is it possible to downgrade from iTunes 11 to 10.7 using Mountain Lion?
I tried to replace it by simply installing the 10.7, but it says that i can't replace a newer version.
Probably the easiest way to get iTunes 10.7 back is to remove iTunes from Applications, download the old version, and then restore the library data from an autobackup
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 & 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:
This will delete the iTunes 11 application.
2) If your Music Library is in its default place, also in the terminal:
3) Using Time Machine restore the following files:
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:
Use Time Machine again to restore the following files:
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!
You can see all the components upgraded/replaced by itunes.11 by opening this installer package with Pacifist.
To restore the itunes related components I removed iTunes 11 as root then restored itunes 10.7 by unpacking the included subpackages with replace / overwrite. Apply administrator privileges, you have to confirm each action to be sure. After all restore permissions, reboot, restore your library. If hit with the 42408 bug You should (probably) restore the DVDPlayback.framework too. You may have to delete some caches, preferences related to the iTunes-Store. Resign and assign again.
In general, you should have a backup before installing a new version as well as one immediately after installing the new version so you can simply restore your system from that backup if you find the new application is not to your liking or has bugs or breaks some other piece of software.
Yes, this is time consuming, but many updates also come with helper applications, frameworks so you can't just restore the older version of the program. Also, iTunes literally modifies the library and database and saves the old library in a special folder just in case you need that older file for when you restore the system to where it was before the update.
I'm sure someone will pick apart every file the iTunes installer actually changed and do the technical work to show how you can avoid using your backup, but I haven't done that work yet (or seen someone blog about how to do this). I am sure we'll get an answer here since I know a lot of people that are going to resist (for good reason) the changes to iTunes and choose to not use it temporarily or permanently.
Also - if you have AppleCare - you can just call Apple for help in rolling back this update. A visit to the genius bar is also worth doing if you either don't have a backup or are not comfortable with restoring your whole system.
"Also, I get some error about the store each time I open iTunes. It's annoying, but I haven't noticed anything that doesn't work. The store seems to work (I didn't try buying anything, but it loads anyway)."
The error you get is -42408. A friend got the same error when I tried to downgrade to 10.7. He did not receive my warning in time, and upgraded. You need to reinstall OS X and reinstall iTunes 10.7. The error you receive is a major problem because you cannot authorize the Mac through iTunes anymore. Try it and you get another error saying it can't be authorized. So iTunes 11 really jacks up the system and going back is impossible without an OS reinstall.
I was able to do it by doing the following:
in the Terminal. If you really want to delete it, run
I don't know if this will make it reappear in the App Store. If so, you'll have to be careful to not reinstall it there.
UPDATE: Apparently you can't disable WiFi Sync except with iTunes. So you'll want to do this in iTunes 11 before you downgrade. There is no (apparent) way to do it on the iPad itself. And you can't do it in iTunes 10 if it thinks your device is broken (unless you restore the device first, which is a bad idea). I guess I should figure out how to make syncing work in iTunes 10, or else I will continue to be blasted with messages that my iPad is broken every ten minutes.
Also, I get some error about the store each time I open iTunes. It's annoying, but I haven't noticed anything that doesn't work. The store seems to work (I didn't try buying anything, but it loads anyway).
And more importantly, playing music works, and it isn't s**t broken like iTunes 11!
