I have an iPhone 7 currently updated to 13.1.3. I'm trying to unload my photographs from the iPhone to Photos on my MacBook which healthy but old enough that I am unable to upgrade beyond OS X El Capitan 10.11.6. I do not use iCloud for my photos so it's a simple transfer from phone to Mac.
For every 100 photos or so that I attempt to import, only about 60 will be moved into Photos on my Mac and the rest are listed as unable to import, files unreadable, and remain on my phone. I had found a thread addressing this issue with a few recommendations, including resetting my Photos library, etc., but I can't seem to find that thread again and cannot find anything related to my issue.
Any suggestions would be appreciated!
