I recently purchased a used macbook and the previous owner left a copy of Photoshop CS 4 on there for me (I don't know if that is kosher or not). But I'm planning on buying the entire Creative Suite by next year, but it is a perk for me to have access to Photoshop for the time being. I'm paranoid about losing access to Photoshop though, so I never update it with the Adobe updater for fear of it asking me for the serial # or it sensing a different IP or whatever it could do. But last night I allowed it to update the updater. Everything works fine still. I just allowed it to update itself, the actual updater program. So i have a few questions: 1. Can people legitimately sell a mac with third party software still on the machine, such as Adobe Photoshop in my case? 2. When I allowed Adobe Updater udate itself from 6 version 6 to 6.0.2, did it talk to Adobe at all with regards to Photoshop, or is that too far of a stretch? 3. If I allowed the Updater to update Photoshop, would it check the serial # or anything at that point, or was the initial installation all there is to liscensing? I'm asking this out of curiosity and because if I am in flagrant violation, I'd rather not be using the program. I'm paranoid about this type of thing too. Thanks!
