Hi, in 2013 I purchased Aspyr's Doom III on GameAgent and played it on OS X.8. Now on Mavericks it seizes to work. The icon opens in the Dock, but keeps blinking and seemingly crashes silently. The system.log says: Is the NSApplicationPresentationFullScreen an indicator of what goes wrong? Am I the only one with this problem? My setup is a CustoMac with a i5-3570K, a GTX 760 and OS X.9.3 (now 9.4). I am aware that id Tech 4 is open source, but I haven't seen a fire&forget Mac OS X binary download "for the rest of us" yet.
