I bought a Mac on ebay months ago, and for a while, all it did was sit and collect dust. Now, I would like to start using it. When I bought the computer, it was just the tower. No software, no cables. Just a tower, the parts inside, and osX 10.2 installed. Here is my problem. When the person who I bought it from, installed the OS, they made an admin account, with a password. Now... when I try to install anything, it says I need a password. What I want to know is if theres anyway to bypass it, hack it, crack it, remove it so that I can reformat the harddrive, or install software??!!
