Mac OS X (10.8) – Install Programs from Unidentified Developers

In this article, I will show you how to enable installation of applications from sources other than the Mac App Store on Mac OS 10.8 (Mountain Lion).

Normally speaking, Mac OS 10.8 only allows users to install applications from 'verified sources'. In effect, this means that users are unable to install most applications downloaded from the internet or stored on physical media without receiving the error message below:

Users can follow the directions below to prevent this error message from appearing.  If you encounter any problem, please contact us by the ways supported on our contact us website.

The following steps can help you install applications from 'unverified sources' successfully.

  1. Open the System Preferences. This can be done by either clicking on the System Preferences icon in the Dock or by going to Apple Menu > System Preferences.
  2. Open the Security & Privacy pane by clicking Security & Privacy.
  3. Make sure that the General section of the the Security & Privacy pane is selected. Click the icon labeled Click the lock to prevent further changes.
