Guest access works with the Find My Mac feature of iCloud 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 Use Find My Mac to locate a missing Mac.
Note: If FileVault is turned on, guests can only use Safari and can’t access your encrypted disk or create files.
