After Monterey update, three processes taking 98% CPU each

I just updated my Catalina iMac 5K to the latest Monterey. After booting up, I noticed the fan noise. I checked Activity Monitor and there are three processes that are taking 98% of the CPU each: AgentPackageMonitoring, XprotectService, syspolicyd. I've attached a screenshot.


Any fix for this bug?


Thanks!

After a MacOS upgrade, it can take hours (depending on the Mac and data) for the upgrade post-processing to complete. There's a lot of cleanup and indexing required to get your Mac back in business.


Give it a day.

" I just updated my Catalina iMac 5K " - and give it some time as in hours or a day to re-index all the changes. And the length of time may be more depending on the amount of Data is on the drive.


Especially with the jump from Catalina macOS 10.15 directly to Monterey macOS 12
