Is Time Machine an easy way to revert to 10.7?

I think you have to go back in time, and replace the iTunes folder (or the xml, itl, etc files), plus the iTunes app.

I'm sure there will be plenty of detailed instructions soon enough. I'm not adding anything to iTunes until I downgrade it.

=Downgrading from iTunes 11 to iTunes 10.7=

You may be able to go back with Time Machine but this may involve restoring other items too (https://discussions.apple.com/thread/4554293?answerId=20441404022#20441404022). Alternatively:

Back up your computer first, in case the unexpected happens.

Get iTunes 10.7. Apple does not keep many old versions on its web site. I always install iTunes by downloading the installer and then keep it on my archive drive so I can have access to old versions. This one is no longer openly linked on Apple's site:

iTunes 10.7 for OS X http://appldnld.apple.com/iTunes10/041-7195.20120912.d3uzQ/iTunes10.7.dmg

Replace the iTunes 11 application with iTunes 10.7. Lion (OSX 10.7) and newer systems have iTunes integrated into the operating system and deleting is a bit more involved. The two ways I can think of to do this are:

1. Use the shareware Pacifist utility (http://www.charlessoft.com/) to install iTunes 10.7 including all associated system files. Details at http://forums.macrumors.com/showpost.php?p=16400819&postcount=6

2. Check this reference on how to delete the iTunes application itself:

Delete iTunes in Mac OS X 10.7 Lion - http://osxdaily.com/2011/09/13/delete-itunes-in-mac-os-x-10-7-lion/

After deleting the application there may be other files that need downgrading too. See the note about error -42408 at the end of this post. You may want to tuck these away somewhere safe until you have completed the installation of iTunes 10.7. I have not tested this but ideally if newer versions are not found then the installer will put in the old versions. This may include these files in /System/Library/PrivateFrameworks/ which apparently get updated by iTunes 11:

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

After doing one of the two procedures above you will have to rescue your old iTunes library from your iTunes > Previous Libraries folder and rename it "iTunes Library.itl" (replacing the existing one in the iTunes folder) because a newer version of iTunes irreversibly updates your library file. Note, this will revert your library to version at the time of the upgrade and you will have to update any changes made since. See:

Alternatively, check https://discussions.apple.com/thread/4556384?answerId=20441424022#20441424022 which requires you have a Time Machine backup (though possibly if you remove the newer version of these files old ones may be installed with the iTunes 10.7 installer - untested).

-> iTunes 10.7

As usual, Apple is slow at updating its pages. The download button on that page just takes you to the main iTunes page with iTunes11 download.

???
It doesn't link to anything.

It directly starts the downlaod of 10.7.dmg.

http://appldnld.apple.com/iTunes10/041-7195.20120912.d3uzQ/iTunes10.7.dmg

The big blue button with "download" in the upper right corner? When I click on it it takes me to the main iTunes page. It directs me to http://www.apple.com/itunes/download/ which of course now points to iTunes11. I tried it in both Firefox and Safari. Yes, it looks like it should download 10.7 but it's an old page (and I have refreshed both browsers).

This is standard for the DL page for a recent version of iTunes until Apple gets around to either correcting the link or removing the version information page completely.

Edit: When I click on your "10.7" in your earlier post it just links to that 10.7 general information and download button page.

That's strange.

The firs link I posted takes me to the info page and click the Download button downloads iTunes 10.7 disk image.

The 2nd link (copied from the info page) downloads the disk image directly.

Okay, now it looks like despite reloading pages it might be caches. I purged Safari's cache and now I see the download link.
