One of my friends and I have both have a MacBook Pro with Retina, and we are trying to play a game through steam together (Borderlands 2). My internet is very slow however, and I was wondering if there is any way to simply play over the WLAN that the MacBook projects out itself in the absence of an internet source when using applications such as AirDrop. We are in the same room and there just seems like there has to be a better/faster way than going through the router, since it is so slow it keeps throwing me out of the game. I tried using Hamachi, but I didn't really get anywhere with that. If this is not possible is there any way to just link the computers together with some sort of thunderbolt cable, since there is no ethernet cable and I would like to avoid buying an adapter.
