When I click on "checking for updates" the wheel just spins. And spins and spins. Nothing happens.
I want to update the system on my iMac. It is currently Big Sur 11.7.1
When I access the system update section of "about this mac" and click on the "Checking for UPdates" the wheel spins. But nothing further. I have tried this eight times, one time letting it spin for 30 minutes. How do I update the system? What is wrong? Thanks!
iMac 27″, macOS 10.13
