A user on a macOS computer downloads a third-party administrative software installer directly from a vendor's website. When opening the installer package, the operating system blocks the launch and displays a warning stating that the application cannot be opened because it was not downloaded from the Mac App Store or created by an identified developer. Which of the following native macOS features is responsible for enforcing this security restriction?
- GatekeeperAnswer
- BFileVault
- CXProtect
- DKeychain Access
Answer
Gatekeeper is the native macOS feature responsible for blocking untrusted application packages that lack valid developer signatures or App Store verification.
Gatekeeper is a built-in macOS security feature designed to ensure that only trusted software runs on a user's Mac. When a user downloads an application from outside the Mac App Store, Gatekeeper verifies that the package has been digitally signed by a registered Apple developer and notarized by Apple. If the developer is unidentified or unverified, Gatekeeper prevents the application from launching by default.
