Photos App on iMac Doesn't See Photos For Import on iPhone since iOS 26
iPhone 16 freshly upgraded to iOS 26, using Photos 8.0 (560.0.110) on 2019 iMac running 13.6.6 "Ventura". Not using iCloud in any way: this is a direct sync to Photos on iMac via USB cable.
I plug in my iPhone, and after the OS recognizes it, Photos says "No Photos" when in fact there are lots. Similar behavior using Image Capture: the iPhone is recognized but there are no photos listed for import.
When I Google this problem, there are LOTS and LOTS and LOTS of people throughout the years reporting the same problem. Very few posts yield a fix, and for the few that do it's never the same fix twice, and none of the scenarios apply to my specific use case.
I've rebooted the iMac and iPhone. I've tried other USB sync cables. I've tried booting to Safe Mode. Nothing has any impact on the problem. Any and all help appreciated.
iPhone 16, iOS 26
