Change Users & Groups settings on Mac
If your Mac has multiple users, you should set up an account for each person so each can personalize settings and options without affecting other users. You can let occasional users log in as guests without access to other users’ files or settings. You can also create groups and choose automatic login options. You must be an administrator of your Mac to perform these tasks.
Both standard users and administrators can join network account servers.
