I've just updated my Macbook Air to Big Sur.

After the update the process opendirectoryd is constantly using about 70% of cpu.

I've searched for the same problem, I haven't found any Big Sur related problems. There were recomendations to disable LDAP and/or Active Directory, but I'm not using any.

After killing the process it appears again. I've searched /var/log/*.log, but I haven't found any errors that can help fix this problem.


It looks like that I have found a way to fix it.

I've edited /etc/auto_master, commented out the line starting with /home and then executed sudo automount -vc.

I've found this solution here: https://superuser.com/a/426719/117432.
