I am happily running OS X 10.5.8 on my AppleTV. I use the device to serve music and am running iTunes 10.1 (54). I am wondering if it's safe to upgrade to iTunes 10.1.2? Can I just rename my existing iTunes in Applications, download the new one and roll back to 10.1 if the new one does not work?
Also does 10.1.2 upgrade the library?
