How do you separate connected photo libraries
I asked a similar question about a week to 10 days ago. I don’t remember the exact wording. I updated my MacBook Air to Big Sur and formatted an external drive. The first time I imported pictures to the Photos library when I backed up my old iPhone. Then when I was backing up again, the computer wanted to link the Photos library on my MacBook with the Photos library on my separate drive. How do I get all the imported photos to only go to the other drive instead of showing them from both libraries?
MacBook Air 13″, macOS 11.3
