 * GateKeeper Gatekeeper in OS X Mountain Lion makes the Mac safer than ever. It helps prevent you from unknowingly downloading and installing malicious software. And it gives you control over which applications to download and run on your Mac. Now you can choose from three security options. You can download and run applications from anywhere, just as in OS X Lion. To be even safer, download and run apps from the Mac App Store and apps with a Developer ID. Or download and run only apps from the Mac App Store — the safest setting of all. Gatekeeper lets you decide which setting is best for you.
