Hi, I have used Rivet in the past and it has worked flawlessly to stream movies. However I have noticed ever since I upgraded to Mountain Lion I cannot get the 360 to see my laptop. I have verified my router/firewall settings and played around with it and still no success. Worst is I have another macbook in the house and the 360 sees it fine and is able to stream movies from it but not my specific mac. Anyone have any ideas for me? I have verified the settings across both laptops and their identical.. I am getting ready to pull my hair out.
