Im helping others by telling them to downgrade, and how.
By wiping their computer???
So I completely wiped my computer and started over, thank goodness I had made a copy of ML 10.8.1 and downloaded a copy of iTunes 10.7 a few weeks ago.
There's many, many posts here outlining much simpler and more targeted methods to downgrade iTunes without wiping a whole computer.
Yes, completely wiping my (their) computer. Being a Beta tester I've found the BEST way to reinstall bad updates (upgrades) is to wipe and re-install.....including iTunes. Otherwise several components will be missing and looking for those is complained for the novelist.
If you have a solid backup (I have 3) it's not that difficult and minimal time investment for a solid operating system. The most time consuming is secure erasing the drive if HDD, second is the install of the OS. Data install time will vary. Actual time invested about an hour total (that's sitting in front of my computer). Total accumulated actual time (for me) less than 3 hours (2 hours of NOT sitting in front of the computer).
BTW, My Beta computer is just that a Beta computer (just for testing). I do have a MAIN computer and my wife has her's (all laptops and all with the same data).
I've read the many post you refer too and to each his/her own.....I prefer my method, but then again I'm blessed to have a beta computer that's not used for critical operations and data storage. Time Machine really makes reinstall a very simple task. I also have a Synology DS with Cloud Station running on all my computers, so all data is synced.
You are correct, there are other ways to downgrade iTunes11 rather than wipe and reinstall. And your recommendation is probably best for the masses wanting to downgrade, I choose an absolute method.
