Description
Gatekeeper settings must be configured correctly to only allow the system to run applications downloaded from the Mac App Store or applications signed with a valid Apple Developer ID code. Administrator users will still have the option to override these settings on a per-app basis. Gatekeeper is a security feature that ensures that applications must be digitally signed by an Apple-issued certificate in order to run. Digital signatures allow the macOS host to verify that the application has not been modified by a malicious third party.
