The macOS system must disable unattended or automatic log on to the system.

Description
Automatic logon must be disabled. When automatic logons are enabled, the default user account is automatically logged on at boot time without prompting the user for a password. Even if the screen is later locked, a malicious user would be able to reboot the computer and find it already logged in. Disabling automatic logons mitigates this risk.
