If you have an unsupported Mac (2009 imac) for Catalina Macos and an IOS 13 supported iphone (iphone X in my case) what happens to syncing your owned Music in itunes? Does it still work? Because I am reading these things about replacing itunes in IOS13 and Catalina and I really really dont want to be left out of syncing my owned music because of this. Can you still sync your itunes music, and your photos with a 2009 iMac running El Capitan and an iphone X running IOS13??
