Bypass Gatekeeper in Mac OS X with Security Preferences
Gatekeeper is an application level security feature on the Mac that aims to prevent unauthorized and unidentified apps from being launched in Mac OS X, thereby preventing potential security problems like exploits or trojans from running on a Mac. The feature is most often encountered when an app has been downloaded from the web, and upon attempting to launch the app a warning dialog will prompt the user with a message saying something along the lines of “This app can’t be opened because it is from an unidentified developer“.
We’ve covered how you can get bypass that error message on a case-by-case basis by using the right-click “Open” trick, but the latest version of Mac OS X brings another option which may be easier for some users to selectively launch apps and bypass Gatekeeper. This is advantageous because users can continue to retain the strict security preference of leaving Gatekeeper enabled and intact, which is generally recommended.
