I have my xbox360 running through my ibook so I know whats up.....Did you follow the link I provided?

Riped from the site:

First off, get all the hardware setup. This is probably the easiest part. Take the cable that comes with your Xbox (or any network cable that fits) and connect it to the back of your Xbox and your Mac. Turn on the Mac and the Xbox (not necessarily simultaneously; probably turn on your Mac first). When your Xbox is on, head to the Xbox dashboard.
On your Mac, head over to the System Preferences and click on “Network.” From the “Show” menu, select “Built-in Ethernet” and set “Configure IPv4? to “Off.” Now head back to System Preferences (click “Show All”) and then go to “Sharing.” Click on the “Internet” button and check the box next to “Built-in Ethernet.” Make sure “Share your connection from: Airport” is selected as well.
Open Terminal (if you can’t find it, just type “Terminal” in Spotlight) and type in the following exactly: ifconfig en0. Hit enter, and it should return something like inet 192.168.2.1 netmask 0xffffff00 broadcast 192.168.2.255. If the first IP is something other than 192.168.2.1 make note of it, and don’t close Terminal.
Now, turn around and grab your Xbox controller. Go to the Network settings, and set the IP Configuration to Manual, the IP to 192.168.2.2, the Mask to 255.255.255.0, and the router/gateway to 192.168.2.1 (the IP that I told you to make note of earlier — if yours is different, input that IP instead).

I'm guessing this is the part thats freaking you out...

Get back on your Mac, go to Terminal, and type in dig and hit enter. There will be a lot of data, but you need to pay attention to only one line. Near the end of the output, a line will begin with SERVER. That’s the line you need to look at. Find the IP address in that line, and highlight it.
Go to the Xbox and go to DNS Configuration. Set it to Manual, and input the IP that you just found in Terminal as the primary DNS server. Set your PPPoE settings to Off and your Advanced to Automatic.
Test your Xbox Live connection. Provided you followed all the steps properly, you should have a connection.


I went throught the same thing...it didn't catch at first but after I restarted my mac and 360 it worked.

So hows your progress?
How about asking the other guy that set it right for a little help.....do you have access to the router to make changes?
