sharing-only user

You can share files and folders with others on your network. You can share your entire Mac with everyone or allow specific users access to only certain folders. Sharing-only users can access shared files remotely, but can’t log in or change settings on the computer.

To give a user permission to access your shared files or screen, you may need to change settings in the File Sharing, Screen Sharing, or Remote Management pane of Sharing System Preferences.
