External photos not importing on Mac
I'm trying to shift to use the Photos App and ultimately I want to share it with family.
So far I've created a new Photos Library (hold down option and open the Photos app) on an external hard drive. I then started Photos, selected the empty library and chose import from the menu, selected about 50 folders of photos (many of which have sub-folders), chose keep folder structure and clicked to import.
When I came back about 20% of the photos had imported, the import had completed (I say that on the basis that it allowed me to kick off another import), but obviously about 80% of my photos hadn't imported.
I'm on Ventura 13.0.1 with all app updates. I've tried it a few times with new clean libraries, but it always seems to only import back to 2017 (which is about 20% of the photos). If I try to kick off another import it imports even less of what is remaining each time.
Any clues?
