You could if it can run DotHalo and the other modding programs. They need .Net Framework to run. I'm not sure if you can have that on a Mac but it's worth a shot I guess.
is there any way to connect the xbox to the mac besides a router? your help is appreciated very much.
Directly connecting them. I don't directly connect my PC and Xbox so I don't know if you need a crossover or ethernet. Probably both would work but I don't know.
