I don't like the new iTunes. I believe the newer versions are a cancer to the mac experience, and I will stick to the old iTunes until feasible workarounds stop existing. For now, I will provide instructions to those of you who want to keep your old iTunes versions going. First and foremost, grab your old iTunes.app and put the precious somewhere safe; where the install touch it. Proceed with your El Capitan install. Once installed: DO NOT OPEN THE NEW ITUNES Do not "test it out", do not even look at it's dock icon lest your eyes accidentally open it. Instead, open terminal, navigate to the applications folder, put your brave cap on, and type the following: sudo rm -rf iTunes.app/ Once done push return, enter your password, and the cancer is gone. It is advisable to make a backup of the cancer so you don't have to download it from the app store, but that's about it. If you've installed *and opened* the new iTunes; congratulations you've performed forcible intercourse on yourself and will have to get your old iTunes library files back to get the old version to work. Unfortunately it's a horrible process and if you don't have any backups then you might as well just go cry in a corner. If you do have backups, google "reverting back from iTunes 12". You'll have to use some third party programs to do a reverse install (I believe pacifist is the program). As of right now everything seems to be working. I have my sidebar, it's colorful, the iTunes store works, and it syncs with my iPhone (still on iOS 8.X). The only error message I do get is something about iTunes not being installed correctly, however this can be solved by simply ignoring it (if someone has a better suggestion please provide input!) Happy listening! P.S. Turn off automatic updates.
