I just finally did this update to macOS catalina, and now I'm having issues syncing my ipod to my itunes. I've been using an ipod nano for years mainly for workout purposes and never had an issue. Now when i connect it to my macbook with a usb cord, it shows its connected in itunes, and thats about it. I can't even eject my ipod from the itunes page, I have to eject from my home screen?! I also have different playlist in my ipod and those no longer show. If I decide to add music it's just added to all my songs. Very frustrating and irritating. Please help me or fix for the sake of my co-workers, b/c i also use it for music at my third shift job. Thank you.
