I've been trying my heart out to get mw2 on my mac, im not pirating it, i purchased it when it came out for my pc. I tried cxz and cider but neither of them have worked. I have also tried crysis 1,which i bought, and that wont install either. Yes i know macs use .dmg and windows uses .exe im not dumb so dont tell me that. but people have been able to play those games on their macs using cider or cxz.
