I have been searching high and wide for other Mac owners that also own a 360 but until now have not been so lucky. I got so sick of hearing problems PC owners had with their 360 and I never had anyone to lend an ear to my Mac/360 problems until now, joy!
Speaking of problems, about that widely known DNS error associated with routers, after reading a few posts, I'm assuming that the problem isn't Mac related (seeing as how it's a Microsoft product).
