I'm not asking for a new/pirated or your product key, I'm simply asking where I can find mine. Here's the dilemma, I have both PC and Mac versions of Halo and I want to sell the Mac version since it goes for 60/70 dollars. I have my PC serial but the Mac version still remains unseen. I've checked Google and all I can find are a just a bunch of nubs asking for a serial key so they can install it. That's not what I'm doing. Anybody have any idea where I can find my product key on my hard drive? It would've been nice if the Halo key viewer for PC was also available for Mac, but things are never that easy.... I've looked at the Halo preference file and viewed it's contents with TextEdit and TextWrangler. They only show a 4-character gibberish word. Maybe I can type a command in the Halo console to view it? The pic is the Halo CD for Mac and the Halo cover sleeve for PC so there are no questions of legitimacy.
