When I connect my iPhone SE to MacOS Photos, not all photos on the iPhone shows up for import.
In MacOS Photos import, it says: Already Imported (483 items) New Items (4 items)
and on the iPhone SE, it says: 1.220 Photos, 40 Videos
Setup: Mac mini (Late 2014, macOS Sierra 10.12.6 (16G1036)) with iCloud account and my wife's and mine iPhone SE (iOS 11.1.2), each with separate iCloud accounts. I want to import all photos from the iPhones to the Mac mini, back them up to iCloud and then delete them from the phones.
