No resolution yet. Apple support confirmed to me this week that iOS 17 is not compatible with OSX High Sierra or earlier. Apparently the file system has changed since iOS 16 so it's tricky to patch and make it work now.
Apple's specifications for the iPhone 15-series phones say that you can use a Mac running High Sierra to manage them. At first they said you needed iTunes 12.9, but then they corrected that to say:
"Syncing to a Mac … requires:
macOS Catalina 10.15 or later using the Finder [or]
macOS High Sierra 10.13 through macOS Mojave 10.14.6 using iTunes 12.8 or later"
So theoretically it is only Macs running the latest version of El Capitain, or running Sierra, that got shut out. I think any Mac that can run Sierra can be upgraded to High Sierra, which would soften the blow for many Sierra users.
People's actual experiences trying to get iPhones running iOS 17 to sync with Macs running High Sierra seems to be all over the board, judging by the various topics here.
