Since OS X Mountain Lion, the Mac defaults to preventing applications from unidentified developers or sources from being launched. You’ll get this Gatekeeper message in OS X 10.8, 10.9 , 10.10, 10.11 or 10.12 when you try to launch any Mac app that didn’t come from a verified source or from the Mac App Store. But we can assure you that M4VGear is 100% clean and safe that you can feel free to install it on your Mac. To bypass the Gatekeeper alert and install M4VGear on your Mac computer, please follow simple steps as below.

Step 1: Go to System Preferences > Security & Privacy
