Hi. I'm not a mac guy but my bro in law has a mac book pro that's a few years old. He knows almost nothing about computers. I suggested to him that he should hook up his mac book to his flat screen to watch movies. I tried some movies from my usb stick on his mac book and they work fine. Here is what the ports on his mac book look like: Is there an hdmi adapter for one of these ports? If so, do you have a link to a site that sells it?
