Apple Intelligence is now available on iPhone, iPad, and Mac!
Running iMac with OS Big Sur 11.6.2, and I know there's an update for 11.6.3.
In System Preferences, the Software Update icon has a red "1" But when I run Software Update, the display shows perpetual "Checking for Updates."
Until recently, Software Update was offering the upgrade to Monterey, which I have been putting off. Now it doesn't even show Monterey.
I have a new MB Pro on the way. Should I just forget about updating Big Sur?
iMac 21.5″, macOS 11.6
This issue has been happening for a week or more unresolved in normal methods.
Possible workaround is to restart in Recovery Mode and choose the Reinstall macOS.
This should bring down the latest version of macOS associated with this computer - Big Sur 11.6.3.
This should not touch any setting, preference or personal files.
Make Time Machine Backup is very useful and can be used to Revert to Previous Working macOS

Safe Mode booting clears a bunch of caches and runs some other maintenance tasks. It can resolve bizarre issues and won't hurt anything so it's worth a try.
Try a Safe Mode boot.
You should notice that the Dock no longer has transparency to its background. That's a clear indicator that you entered Safe Mode. Give it a couple of minutes to finish loading everything. You could attempt to check for updates at this point or reboot normally and try again to update.
You are welcome and thank you too.
Do come back to the ASC Forums, in the future, if / or when additional question may arise
Software Update runs with no result
