I'm trying to help this guy sort something out. he's trying to share a 802.1 X Wi-Fi connection over the thunderbolt Ethernet adapter with his PS3. he has a retina MacBook pro base spec. when trying to share the connection the Ethernet one doesn't show up, yet the PS3 knows that there is a network, it gets an ip address but no further. we've managed to get this working with a base 13" mbp and an Xbox. I'm just wondering why the Ethernet adapter connection doesn't show in the list of adapters.
