Let me know what you find out on this because I wondered the same thing. I have no idea why Aspyr would port this to Mac and then make it incompatible with online PC users. I don't even see why it shouldn't work. My understanding of online gaming is that just control instruction scripts are sent from client to host and visa-versa. The client computers do all of their own rendering on their local cpu. So why would Mac control scripts be different than PC control scripts going to the same host. The online Stars Wars gaming is going to be huge when it gets going. My sons, and everyone of their friends are dying to waste time on this service. It should be bigger than Sonys EverQuest or Microsofts Asherons Call. Too bad Apple users will be left-out, AGAIN! Greg
