Can't import my library “Photos Library” i. Photos App says it is a newer version of Photos. Please upgrade Photos to open this library.
I got this message "The library “Photos Library” is from a newer version of Photos. Please upgrade Photos to open this library.".
I had to format my Mac mini and I did a copy on external drive. When I try to use my Photos shows this message.
What to do?
Mac mini, macOS 10.15
