I have a Macbook Pro running OSX 10.7 right now, and it is connected via Wifi, and a Mac Pro 1,1 running OSX 10.9.2 which does not have a Wifi adapter installed on it. What I'd like to do is share the internet connection from my Macbook Pro with my Mac Pro via ethernet. They are both connected with a wired ethernet hub, along with my Xbox. I went to System Preferences -> Sharing and enabled internet sharing on both devices using the appropriate methods of connection. Nothing is working so far. I've searched google, but I only find articles about creating a wifi hotspot, which isn't what I need. Lastly, I'm using a neighbour's wifi signal, so I can't connect to the router directly, otherwise I wouldn't be posting this. Any ideas? Thanks. Shogun.
