Mac OS 10.13.6 Compatible with iOS 15 ?
I have a mid-2010 iMac and cannot upgrade the MacOS beyond 10.13.6. My iPhone and iPad are running iOS 14.8. I’m afraid to upgrade my iOS devices for fear that functions on the Mac will break.
Does anyone know if there are known incompatibilities between High Sierra and iOS 15?
