iTunes 12.8.3.1 won't connect to iPhone 12 Mini
I just bought the new iPhone 12 mini. All of the set up steps seemed to go ok until I tried to connect to iTunes on my MacBook Pro running mac OS 10.13.6, via a USB cable. At first it simply said it was not authorized or something, despite entering the password on the phone and "allowing" the phone on the laptop. So I ran some updates to ensure I had the latest iTunes (12.8.3.1) as well as the latest iTunes device update and the latest 10.13.6 security updates. The phone will still not connect to iTunes. It connected fine to Photos which is much older, Version 3.0 (3291.13.230) from 2017! I have tried alternating the USB ports, as well as trying different newer cords, non of which made a difference. Since the vast majority of my music library consists of years of CD's I have imported, I cannot get any of that music onto my new iPhone. Before buying the phone I had been reassured by multiple Apple store workers that it would not be a problem even with the Mac OS I am running.
