Yes I know what you're thinking, "Of course Day Z doesn't run on Mac". I didn't find out until I clicked "Play" and the Error Message popped up. However, with no warning at all, Steam just allowed me to download Day Z Standalone even though it would run on a Mac. At least I thought it would when I saw someone playing the game on their Mac on YouTube. But now I realized they probably messed with their Mac in order to run the game. So sadly I'm short $30 as the Day Z Standalone Store Page never mentioned it ran on PC only. The requirements section included an Intel HD Graphics 4000 which is what my Mac has (this also being the reason why I thought it would work). So since Steam has denied my refund, for now at least, I would like to know if I could get my money back or at least trade my game for something else. Please advise, and thanks for putting up with my stupidity.. :D
