So, I own halo 1 for mac, and dont have any way to get the code. I cant find any extractors that work, nor do I still have the box. Now, I'm tempted to just go buy a new copy, but although you can buy Halo PC for around $20 from amazon, the lowest price for Halo for mac is $94.25 (wft?), so, I was wondering, do I still have to use the key online to be able to use it for reach?
