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
Follow the steps at > Update macOS on Mac - Apple Support
If that doesn’t help, see > If an error occurred while updating or installing macOS - Apple Support
Also worth mentioning, third- party AV-ware, Cleaning-ware, Optimizing-ware and VPN’s can block your system from updating and from preforming correctly.
If all else fails try installing from the Safe Mode according to How to use safe mode on your Mac.
NOTE 1: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following;
• Verifies your startup disk and attempts to repair directory issues, if needed
• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)
• Prevents Startup Items and Login Items from opening automatically
• Disables user-installed fonts
• Deletes font caches, kernel cache, and other system cache files
NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.
What year model is your iMac?

You need a 2015 or later iMac model to upgrade beyond Big Sur.
the Imac is from 2019
When I click on "checking for updates" the wheel just spins. And spins and spins. Nothing happens.
