The macOS system must enable firmware password.
Description
Discussion Text
A firmware password must be enabled and set.
Single user mode, recovery mode, the Startup Manager, and several other tools are available on macOS by holding the "Option" key down during startup. Setting a firmware password restricts access to these tools.
To set a firmware passcode, use the following command:
[source,bash]
----
/usr/sbin/firmwarepasswd -setpasswd
----
NOTE: If the firmware password or passcode is forgotten, the only way to reset the forgotten password is through the use of a machine-specific binary generated and provided by Apple. Users must schedule a support call and provide proof of purchase before the firmware binary will be generated.
NOTE: Firmware passwords are not supported on Apple Silicon devices. This rule is only applicable to Intel devices.
