Can't open my photolibrary on a TimeMachine backup
I am trying to open my photolibrary on my TimeMachine backup to recover a photo I deleted about 4 months ago. I can find the photolibrary on my TimeMachine backup disk, but I can't open it and I get this message:
"the operation can't be completed: PHPhotosErrorDomain fault 1000"
Any ideas what I can do?
