| Um. i think you'll find that the current xbox probably uses DirectX..
and in THEORY, the new xbox should make porting EASIER, not harder. any CPU specific code is more likely to be easier to port to Mac than X86, as it will already be PPC code. not PPC mac, but PPC none-the-less.
also what 6.1 system are you using?
