Guest user
You can let other people use your Mac temporarily as guest users without adding them individually as standard users.
Guests donβt need a password to log in.
Guests canβt change user or computer settings.
Guests canβt log in remotely when remote login is turned on in Sharing settings.
Files created by a guest are stored in a temporary folder, but this folder and its contents are deleted when the guest logs out.
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.
Note: If FileVault is turned on, guests can only use Safari and canβt access your encrypted disk or create files.
