    I'm buying the apple mini displayport to dual link dvi adapter tomorrow off someone on craigslist, I'm not meeting near an apple store so I can't really test if it works or not, the seller says its new in box but I'll open it there. How can I tell if it is real/working or fake using just my mac?
