By default, macOS allows a Guest user account that allows access to general macOS system and apps without login credentials. The Guest user is considered a security vulnerability because it has no password associated with it.
It is recommended the Guest account be disabled on all macOS systems unless there is a clearly demonstrated need.
When enabled, Kandji will ensure the Guest user feature is disabled. During each check in, Kandji will verify, and adjust the settings back to the disabled state, should it change.
Disabling this parameter stops Kandji from disabling the Guest user feature during each check-in. The feature will remain disabled until a user enabled the Guest user again.
