It explains things beautifully Daniel.
They made a DX version for Mac - but it's not DX11, it's not even DX anything, it's DX Mac, and it still needs specifically programmed for the Mac - no existing DX games can be ported automatically, it's just an option for multi-platform development.
There is no way that FPSC will run on a mac without running windows too, with it's own DX version. So my question is really, Why? - why would you go and buy a mac, spend twice what you would compared to if buying a PC, then go and install a PC OS on it, and use it just like if it was a PC. Why not just buy a damn PC!
People should look at other avenues for mac development, and not force a horse into the back of a taxi. Ok that's a weird thing to say, but I know what I mean
