Description
Gatekeeper must be configured with a configuration profile to prevent normal users from overriding its setting. If users are allowed to disable Gatekeeper or set it to a less restrictive setting, malware could be introduced into the system. Gatekeeper is a security feature that ensures applications must be digitally signed by an Apple-issued certificate in order to run. Digital signatures allow the macOS host to verify the application has not been modified by a malicious third party.
