My Mac software will not update, it freezes.
iMac 27″, macOS 11.6
Please restart the computer in Safe Mode per the directions in the How to use safe mode on your Mac - Apple Support link.
Note: If you are using a wireless keyboard please either plug it in using the supplied Lightning cable that shipped with it. If you are using a legacy keyboard or a third-party keyboard that does not have re-charging abilities, please use any USB keyboard. Also note that a Safe Mode restart may require you to hold down the shift key for up to 5 minutes before the computer starts in Safe Mode. You will know it is in Safe Mode when you see “Safe Mode” in the upper right of the display.
Next, please download and install your Mac OS update and then restart normally and please retest.

I did as instructed. Plugged in my keyboard, shutdown and restarted in safe mode as verified on top right of screen, i then signed in and tried to update and there is no change. It gives the message “Checking for Updates” & the wheel keeps going around but nothing happens.

I don't know why it worked but I was able to update Big Sur finally.
Restart with safe mode then restart with normal mode and again restart with safe mode, restart with normal mode.
It may sound ridiculous but repeating this procedure enabled(normal mode) my iMac OS Big Sur update.
my iMac (Retina 5K, 27-inch, 2019) will not update to latest software. It is currently running on Mac OS Big Sur and press "software update" it says "Checking for updates" and nothing happens. I had/have Auto update on but it never updated.
