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

高等級 1自動化macos

說明

macOS has a privilege that can be granted to any user that will allow that user to unlock active users' sessions. Note: For organizations that are using Platform Single-Sign-On (PSSO), this setting can cause issues with syncing with your PSSO. See the note in the audit to verify if you are using PSSO. Audit: Organisations using Platform SSO (app-sso platform -s shows a configuration) should not apply this change.
