No decent game ever comes to MacOS (at least not in the same century it was first released on other platforms), so I don't understand the outcry. Most Apple users simply don't have the hardware. In the mobile sector only the more expensive MBP 15 comes with a (mediocre) discrete graphics card and also the 21,5 iMac does not have one at all. The iMac 27 has a discrete GU with 2GB Vram which is also not sufficient for high end games any more (on my Notebook I have 8GB Vram -GFX 980m). So let's face it: Mac is not for gaming.
