How to downgrade iTunes 12 to 11.4?
I recently upgraded iTunes to 12.0.1 and want to downgrade back to 11.4. I run the 11.4 installer and it says "A newer version of iTunes is already installed." So I use the terminal to delete it (sudo rm -rf /Applications/iTunes.app/) and also trash the preferences as well as Library/Caches/com.apple.iTunes. Now I'm able to run the 11.4 installer, but when I launch iTunes, I get an error: "A required iTunes component is not installed. Please reinstall iTunes (-42401)." Any ideas on how I can successfully downgrade iTunes to 11.4?
It needs to be 11.4 since I share my iTunes library between two macs via file sharing, and one of them is an older mac which is unable to upgrade to version 12.
Any help appreciated! Thanks
