my 2008 mini running snow leopard keeps throwing an error window whenever I open it. The message is to download a new version of iTunes to sync my phone. It started after I tried syncing my iPhone 6S+ to it. My best guess is there's something in iTunes telling it to sync and since it can't, it keeps throwing the error message. I've turned off auto sync and there's no backups tied to the device. I tried to plug the device in to see if it will allow any different options. None that I see. I still use this version as my server for the rest of the house. This I can't seem to get rid of. Thanks in advance.
