Ensure an Administrator Account Cannot Login to Another User's Active and Locked Session

高レベル 1自動macos

説明

macOS has a privilege that can be granted to any user that will allow that user to unlock active users' sessions. Disabling the administrator's and/or user's ability to log into another user's active and locked session prevents unauthorized persons from viewing potentially sensitive and/or personal information.
