Shared iCloud Photo Library on Mac with Big Sur
I have a shared iCloud Photo Library that works well to share photos with my partner on both our iPad and iPhones. I do not seem to be able to access the shared library on either mine or my partners profiles on our rather ancient iMac that (can only) run Big Sur 11. Is there something I am missing or is it not possible to access shared photo library on Big Sur?
