okay, I'm on 10.9.5 and pressed "ok" to the update prompt in iTunes without thinking about it. now my machine has iTunes 12 installed, and it looks awful in mavericks, and i don't like how it was rearranged. how can i go about downgrading to iTunes 11 without losing my music, and apps? I unfortunately don't have a backup of my machine from before i made the changes, so thats not an option. can someone please walk me through the steps to downgrade? thank you!
