GunsUp26 posted a topic in OSx86 10.9 (Mavericks)I recieved the Valve Steam Machine to test, I decided to get a wild hair and just use MyHack. I used it and no issues at all. Used "IGPEnable=No" and it installed and flowed great! This is the system running though the HDMI IN on the Alienware M18XR2. I have the Steam Machine running OSX Mavericks and Final Cut Pro X.
