From Google, I found their website APIN LimitedWhat did the manufacturer's web site say when you went there to check Mac compatibility?
Thanks for your reminder.It does use the USB port according to what I read on their site but that doesn't make any sense to me. As far as I know, the only way to extract video from your MBP is through the mini display port.
You might want to get your hands on one and test it out before buying.
Regards.
