Clearly having a CS degree from Stanford doesn't do you any good if you can't set up Internet sharing on a MacBook Pro running Snow Leopard! What gives? I have a valid Ethernet-based Internet connection. I've tried various combinations of AirPort on, off, sharing a new connection, etc. but it doesn't work. I did have VMWare/Parallels installed at one point - is it a permissions issue? I've installed all the latest updates. Thanks in advance.
