LowOS hardeningBLWK-MAC-006

The guest account is enabled

What this means

Anyone can log in to this Mac as a guest without a password. Guest sessions are limited, but they still give a stranger a foothold on the machine.

How to fix it

Turn it off in System Settings → Users & Groups → Guest User.

Check it yourself

Run a scan and look for BLWK-MAC-006 in the results:

bulwark scan

Installed the standalone CLI package instead of the app? The command is bulwarkctl.

How Bulwark decides

Bulwark reads macos_security and reports this check when:

guest_enabled_known == true and guest_enabled == true

If a value can't be read, Bulwark reports the check as undetermined rather than passing it. View the rule source.
