Overcoming the Unity bug when running Shadowrun Returns on Mac OS X Mountain Lion

Last Thursday, Shadowrun Returns was released, to an eagerly expectant group of kickstarter backers, myself included. Imagine my disappointment when I had installed it, and it crashed during startup.

• Save the file
