I have 2017iMac running Catalina- it won't upgrade to Monterey
I have a 2017 21.5" iMac running 10.15.7 MacOS. When I go to update the Mac OS in System Preferences, it gives me the spinning ball of death.
I have also tried going to Apple support and clicking on the OS update which takes me to the app store- which sends me back to Software Update in System Preferences.
I have plenty of space (470GB free on a 1TB fusion drive).
I have disconnected external drives.
Suggestions?
Thanks.
