iMac Software update stuck on macOS Catalina 10.15.7
The updates for my iMac do not work. The software update keep searching for updates but not finding them. If I look new macOS versions in the app-store and try to "get" them it just returns to my software update screen looking for updates. I already restarted in safe mode and already reset NVRAM.
I am working on iMac Retina 5, 27 inch, 2019 - current version Mac OS Catalina 10.15.7.
What should I do? And which update should I install?
