This accured about a month ago when I updated my laptop 2 updated ago. Every time I try to log in I get this error as in the picture mentioning in dutch: 'Verificatie mislukt Er heeft zich een onbekende fout voorgedaan.' I changed my password and it keeps giving me this error. There is also nothing wrong with my connection. I hoped that this would be fixed when I updated to Big Sur but it is not please help.

Are you running any anti - virus programs? Using a VPN?


Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Also try the Safe Mode. 


Isolating an issue by using another user account   


Safe Mode - About.       


If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor.  Please use copy and paste as screen shots can be hard to read. Click “Share Report” button in the toolbar, select “Copy to Clipboard” and then paste into a reply. This will show what is running on your computer. No personal information is shown. If the log won’t post, try posting it in Pastebin and provide a link in a reply. After pasting the report in a PasteBin page, go to the top of the page, and copy the address in the URL bar. Paste that in a new reply.        Pastebin.

I hadn't seen your last post before today.


I would uninstall CleanMyMac using the Developer's uninstall instructions. Most long time posters recommend not using cleaning programs. They can destroy normal computer operations.


Try removing all the login items from your user account and then restart the computer so you don't have any applications running. See if you have the same problem(s).
