This article explains how to disable and re-enable Gatekeeper in Mac OS X 10.8. This is vital for users needing to use the cVPN with Mac OS X 10.8.
OS X 10.8 features a new security feature called Gatekeeper which prevents the installation of malware by controlling the types of software that can be installed. At this time, many developers have not released signed versions of their applications and installers. To enable installation of these applications, Gatekeeper must be disabled at the beginning of the installation process.
Note: Gatekeeper only needs to be disabled during the initial installation and running of the application; after that, it can and should be re-enabled.
After updating any necessary software, follow the above instructions until step 5, and click the radio button next to Mac App Store and identified developers. Then close the System Preferences window.
