Change Guest User settings on Mac
If you’re an administrator of your Mac, you can use Users & Groups settings to let other people use it temporarily as guest users without adding them as individual users. Learn how to set up a new guest user.
To change these settings, choose Apple menu 
in the sidebar, then click the Info button 
next to Guest User on the right. (You may need to scroll down.)
If a guest is logged in to your Mac, you can’t select Guest User.

Guest access works with the Find My app to help you find your Mac if you lose it. You can locate your Mac if someone finds it, logs in as a guest, and then uses Safari to access the internet. See Set up the Find My app to locate a missing Mac, device or item.
