It is shocking the effort required to have a good gaming experience on Apple computers (excluding iOS). They always struck me as agnostic to games, yet in recent years it appears to border on open hostility.
They made gameportingkit, which got made into whisky app. So not totally hostile
It was Jobs specifically that was anti-gaming. I'm not sure where Cook stands.
Apple has always been anti-gaming. It's been in the companies DNA since the first Mac was derided as a "toy" for having a graphical user interface, and they overcompensated trying to make it a business machine with no games.
About once a decade someone inside of Apple who is really passionate about games pushes some project through - you had GameSprockets in the 90's, you had someone convincing Valve to port Half-Life, you have GamePortingKit now, but it's just not in the companies culture to give game developers the long-term support they need.
