I got my hands on a used G5 powerpc with dual processors and loaded with adobe editing software galore but guess what, I can't update anything without the main admin user name and password and the only one I've been able to find and change in the terminal has been the login admin and password. Nope I don't have the original install cd's for the computer and the guy I got it from only had it for 6 months before he decided to sell it himself. I've been able to find the original owner through documents he left on the computer ( let this be a lesson to anyone donating or giving away or selling a used computer to thoroughly wipe the drives and reinstall the os or just remove the hard drive all together ) but his wife had no idea what the password was. Looking around on ebay a used legit edition of os x leopard goes for $100 - $150 and new is $200 - $260 and craigslist has been a bust. Anyone here have an idea on what else I can do to try and get this resolved?
