Hi, I bought a macbook pro 13 inch tonight at PC world and am now in a bit of a pickle. When I bought it, the sales assistant said he had to go grab it from the warehouse and would take 5-10 minutes. He came back and said that the product had been opened, but didn't really make a big deal about it. (Big mistake on my part). I decided to buy it anyway because it was the last one and it was late. I got home and when I booted it up, it had already been charged to about 75% and there was an account on there already. The account is under a name (Employee perhaps?) with a password. The only other option was a guest account to log into. I tried that but I couldn't really do anything because I needed the admin password. I am now in the process of reinstalling the operating system and hopefully can create a new account. My question is though, is it worth taking this back? What exactly was someone doing on it before hand? The computer and cables are all in perfect condition with no smearing. Great first mac experience, oh and my poor wallet.
