Photos library showing grey boxes after restoring from backup
I had moved my photos library to a new macbook and when I opened photos it is showing my entire library but as grey boxes. Please help me fix this!
I have already tried repairing the library. I never had the library on icloud, only local copies. I've attached an image of what they look like. It remembers the date and time and location of the photos, I just can't see them.
MacBook Pro, macOS Sierra (10.12), null
