Also people need to realise, devs require some form of support on the platform they are building on with the tools to use them on, apple dont provide any support to a dev, its all down to the dev, this means any changes that apple makes, is at their whim and upto the devs to constantly catch up, PC has many tools and the development tools have far better support and these notes go out in advance so they can update when needed.
Apple hasnt supported any games to be released on to the platform, its all done through the developer. Also, if people are running this at the retina resolution, then thats your fault if the game is tanking...
