What is the system photos library
I'm trying to set up iCloud Photos on my Mac and it gives tells me it is only possible in the photo systems library. What is that and how can I correct the issue?
MacBook Pro 13″, macOS 12.1
The system library is the "standard" library on your mac, you can select what library is the system library
