I've seen several threads about a different WiFi card you can buy for a mid-2012 Retina MBP that allows the Apple Watch to unlock it. And I was wondering if there was a similar card available for the mid-2012 Unibody MBP. I've been wanting this option ever since I got a watch but haven't been able to find anything on how to do it with a Unibody MBP. Is this at all possible? Or am I out of luck?
