My complete feedback with iOS 16 and Mojave
Positive points:
After updating to iOS 16.0 via the smartphone, when plugged into the computer an upgrade is downloaded so that iTunes recognizes the iPhone.
Synchronization of music from iTunes 12.9.5.5 works, as well as pictures and albums from iPhoto.
Calendar and Notes still sync well via the cloud.
Reminders also syncs if you refused to upgrade on the iphone (like in iOS 15).
Negative point:
It is no longer possible to directly download photos taken on the iPhone with Mojave applications.
Image Capture (like the iTunes import module) displays an error message when importing photos that were taken on the iPhone.
Deleting images on the iPhone from the Image Capture application still works.
Good news, i managed to import from the iPhone, with Image Capture and iPhoto, images in all formats (jpg, png, tif) that came from my other cameras like Nikon & Panasonic, or from androId cameras that I had received by SMS.
For photos and videos stamped "Apple manufacturer", I tried on the iPhone to duplicate them, modify, delete and then restore but nothing happens, there is always this damn error message.
On Mac I tried to re-authorize in the system preferences the full access to the above mentioned applications, but without result.
I can only hope that Apple will correct what seems to be a small bug...
Fortunately, there is still an alternative way to get the photos taken on the iPhone:
the easiest way I found is to send the images from the iPhone to the mac using AirDrop.
It also allows to transfer Raw images from recent iPhones (which are not compatible with iPhoto) to the computer.
The copy is quite fast, maybe faster than via a USB 2 cable, but if you take a lot of images on the iPhone, it adds a few steps that you didn't have before.
