Two Methods:Exception for One Specific SoftwarePermanent Change to for All Software
Whether it’s protecting users from malicious software or simply trying to push purchasers to the Mac App Store, the new Gatekeeper feature in Mac OS X Mountain Lion can get in the way when it comes to installing software. By default, a Mac running Mountain Lion will block the installation of apps that are not from the Mac App Store or created by identified developers. But what if you know the software you are installing is safe even if it didn’t come from the Mac App Store or an identified developer? Here’s how to sneak past that stubborn Gatekeeper!

EditMethod 1 of 2: Exception for One Specific Software
-
1Download the software as you normally would from the internet. If asked if you want to "keep" or "discard" the file, select keep. Note that you should only do this if you are certain you trust the publisher of the software.Ad -
2Open the software and get the error message that your software "can't be opened because it is from an unidentified developer." Click OK. -
3Try opening the software again but this time right click on the software. (You can right click on a Mac, by pressing ctrl and clicking simultaneously). Select open from the menu. -
4You should now be given the option to open the software. Click "open".

EditTips
- If you primarily download software from the Mac App Store, you can select the Mac App Store setting from the Security & Privacy pane within System Preferences to allow all apps downloaded from the Mac App Store to be installed on your Mac.
- You can switch settings as often as you want to so, if you know a piece of software is safe to install, you can turn off Gatekeeper, install your app and then return to System Preferences to change the setting back to Mac App Store and identified developers if you wish.
EditWarnings
- While it can be annoying, the Gatekeeper feature is designed to protect you. If you do set your Mac to allow all software to be installed, make sure you’re certain that the software you are installing is legitimate.
