Photos app not finding library
I just set up a new macbook pro using a time machine backup from my mid-2010 macbook pro. When I try to open Photos, I get the error "Photos cannot find the System Photo Library named “Photos Library.photoslibrary”". Nothing from my Pictures folder is selectable when I try to find another library for it to open and I can't find "Photos Library.photoslibrary" with a search. I do have an "iPhoto Library.migratedphotolibrary" in my Pictures folder, which can't be opened because it's already been migrated. How do I get Photos to open my photos? My old computer works like a charm (but can't be upgraded past High Sierra), so I can still access them there. Thanks!
MacBook Pro 14″, macOS 12.3
