Photos
I just got a new iMac and migrated everything over from my old iMac using the most recent backup from my Time Capsule. When trying to open Photos I get a message "The library could not be opened" with "Photos was unable to open the library "Photos Library". (4302)
The Photos window also shows that Updating Library . . . is 100% complete.
The only two options it shows are Quit and Open Other.
I've tried creating a new library but it still won't open.
Photos worked on the old iMac, but often spontaneously shut down when working with large files.
