Change Users & Groups Sharing Only User preferences on Mac
On your Mac, use Users & Groups System Preferences to create “sharing-only” users to share files and folders with others on your network. You can limit access to your shared information and computer. Sharing-only users can access shared files remotely, but can’t log in or change settings on the computer.
If you’re an administrator, you can reset the password and change the picture of a sharing-only user. Learn how to set up a sharing-only user.
To change these preferences, choose Apple menu 
, then select a sharing-only user in the list on the left.
