I have never encountered a program that I have PAID for that randomly crashes my entire computer at random. I'm willing to overlook how horribly optimized this game is for Mac OSX because it is playable on my machine, but I am appalled that this game is so shoddily put together that the developers will seed versions of this software that cause the user's computer to completely fail. Even in all my years of PC gaming and professional multimedia design on Apple hardware I have not encountered such poorly implemented software.
I love this game and you will continue receiving my money, but seriously stop embarrassing yourselves as developers.
I'm running a 2008 macbook pro 2.2ghz dual core 128mb 8600m gt 4gb of ram
I usually am able to run the game at around 40fps on medium settings with the shaders on low although I have locked the frame rate to 32 because of heat concerns. I would give you the error log but none was generated as the software requires me to shut off the computer to restore functionality
Keep in mind that this is a professional machine that runs Final Cut Pro and the Adobe suite of applications at blazing fast speeds without hiccups, but can't handle your silly video game without all these problems.
