Change User settings on Mac
To change these settings, choose Apple menu > System Settings, then click Users & Groups in the sidebar. (You may need to scroll down.) Click the Info button next to a user on the right to make changes.
Note: If you’ve forgotten or need assistance with a login password, the following topics may help:
Click the picture that appears next to your username or someone else’s username in the login window on your Mac. You can choose a photo from your photo library, take a new photo using the camera on your Mac, choose a Memoji or emoji, use initials in a monogram and more. When you choose a picture or other image for your user login picture, the selected image is also displayed for your Apple ID picture and for your My Card in Contacts. See Change a user’s login picture.
Change or Reset
Change the login password and password hint for the user who is currently logged in, or reset the password for someone else’s account. See Change a password or user picture.
Allow this user to administer this computer
Allow the user to be an administrator for this Mac.
Allow user to reset password using Apple ID
Allow a user to change their password for this Mac at login by entering their Apple ID and password.
To use this option, the user must have set up iCloud on this Mac. However, this option isn’t available if FileVault is turned on and set to allow the user to reset their password at startup using their Apple ID.
Open Contact Card
View and edit a user’s Contacts information. This is only available for the user who is currently logged in.
Delete a user. (This option doesn’t appear if the user is currently logged in or if there is only one user set up. You may need to enter an administrator password.)
To change or update a user account name, see the Apple Support article Change the name of your macOS user account and home folder.
To give a user permission to access your shared files or screen, you may need to change options in File Sharing, Screen Sharing or Remote Management settings. See Set up file sharing and Share the screen of another Mac.
