I've been looking at a lot of used MBPs on Craigslist and Letgo, and a lot of them have Adobe CS6, which I am interested in, but there's so many that have it I wondered if it came with the MBP at one time. I am concerned because most of them don't have a key with it, so I don't want stolen software. They aren't all the same person, so it makes me think it was loaded by Apple at one time.
