Ensure Automatic Login Is Disabled

高レベル 1自動macos

説明

The automatic login feature saves a user's system access credentials and bypasses the login screen. Instead, the system automatically loads to the user's desktop screen. Disabling automatic login decreases the likelihood of an unauthorized person gaining access to a system.
