I made a copy of my Photos library on an external HD. When I try to open them it says it can't open a migrated library. Why is that?
iMac 21.5″, macOS 10.15
If Photos won't open a library that you already migrated
Photos lets you know if you try to open an iPhoto or Aperture library that you already migrated.
If you try to open an iPhoto or Aperture library after you've converted it to a Photos library, you'll see a message that Photos "Cannot open migrated library."
Click Open Photos to view the library in the Photos app. Or you can open the original library in iPhoto 9.6.1 or Aperture 3.6.
