Description: 

After updating iOS Big Sur to 11.6.3 on my 2015 iMac, I cannot sign-in

to my Apple ID. The sign-in window just loops back to the original s

ign-in window after completing the ID, PW and Enter. My Apple ID and 

PW work when I open Safari and sign into iCloud.com. 

I have used Big Sur for two months with out incident. 

FaceTime, iMessages and iCloud also keep asking for sign-in credential

s, yet won’t except password. They do not state incorrect pw, they ju

st loop back to original request sign-in window.

End of report

After running the EtreCheckPro, I found and deleted the hidden antivirus software AVG and CleanMyComputer. Running again only showed some unsigned Canon Certificates.

Unfortunately I still have the sign-in loop problem.

After resetting nvram, I was still unable to sign into my Mac with Apple ID. I was, however, able to sign into my iCloud internet account email. (Sys pref > Internet Accounts > iCloud)

Afterward I again tried to sign into my Mac with my Apple ID, but continued stuck in sign-in loop.

I also tried FaceTime sign-in again, this time it stuck in limbo.

Any help is greatly appreciated.
