Change Users & Groups Guest User preferences on Mac
If you’re an administrator of your Mac, you can use Users & Groups System Preferences 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 preferences, choose Apple menu > System Preferences, click Users & Groups , then select Guest User in the list on the left. If a guest is logged in to your Mac, you can’t select Guest User.
Note: If the lock at the bottom left of the pane is locked , click it to unlock the preference pane.
Allow guests to log in to this computer
Allow guest users to log in to your Mac without entering a password. To turn on guest access, select Guest User in the list on the left. Guest users can’t log in remotely.
If FileVault is turned on, guest users can access Safari, but can’t access your encrypted disk or create files. You can also prevent guest users from accessing adult websites.
When a guest user logs out, all information and files in the guest user’s home folder are deleted.
Allow guest users to connect to shared folders
Allow a guest user access to shared folders from another computer on your network.
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.
