I have a iMac running 10.5.8, about three feet from my older model 360. My wireless router and modem are downstairs (where they need to stay). Now, my iMac is connecting to the internet over WiFi, and what I would like to do is share my iMac's connection with my 360 over the ethernet port. I don't have (nor will i buy at the outrageous price that Microsoft is charging) the 360 wireless adapter, so I figured this would be the best way to get this Xbox online. I had it configured this way in the past, but I can't get it working again. HELP!
P.S. When I am testing my connection on the 360, it can connect to the network, but not to the internet. It says that my "DNS server can't resolve Xbox LIVE server names". I attempted typing in the DNS settings from my Mac, and that didn't work.
