Finder sidebar will not show any devices
I wanted to add new music to my iPhone 8 using my new MacBook air. But I find that no devices will show up in the Finder sidebar. I plugged in my external hard drive and its icon appears on the desktop but it does not show up in the sidebar. System report shows both the iPhone and the hard drive are connected. Tried Finder prefs, changing cables, changing USB ports, restarting, upgrading software, all the common fixes. Nothing. Spent an hour on the phone with Apple Support, went through all the steps again, finally they had me reinstall MacOS on the MacBook. Still nothing. I'm beginning to think it's a glitch in Ventura. Any thoughts?
