Fotos can open my library, but if I try to import that library into another one it asks for it to be repaired
I have a new Mac and I'm trying to consolidate several libraries since I have more space now. I have like 15 libraries in a NAS plus my current one from the previous Mac. All copied into the new Mac.
Most of the NAS libraries I was able to import into the System library of the new Mac, but the last 3 and the one coming from my old Mac I can't. It says the library has a problem and needs repair.
The weird thing is that if I just try to open the library in Photos by holding the option key when opening Photos, it works. Forcing the repair does nothing. Photos can still open the library but it wouldn't import it.
