Mojave and iCloud Photos
Since I began using shared libraries on on my MacBook Pro (M1 Ventura), I lost access to photos on the cloud from my MacPro running Mojave (Mid 2010, processor upgraded to run 10.14.6). I have tried the usual range of fixes (signing in and out of iCloud, rebuilding the library, etc) but to no avail.
Any insights or solutions (other than getting rid of the MacPro) would be greatly appreciated.
Mac Pro, macOS 10.14
