I was looking for a macbook pro, someone advised that I check the local listings on Craigslist. So I looked around for a couple of days and purchased a macbook pro yesterday from a person on craigslist. He gave me the serial number and the screenshot of the Apple Serial number website he also said there was a firmware issue and Apple Care would cover it and provide information to fix it. I called Apple I wanted to make sure it was not stolen, or had any other issues. The representative Chrise whom I spoke with at Applecare informed me that the computer was clean, and had not been flagged for any reason. She also informed me that the computer had 3 years of Apple Care and that I should have no problems till it ran out. In fact she even emailed me a link for the firmware unlock which she said would be simple to fix. Yesterday feeling better that I was making a safe purchase, I met the seller at a Target and bought the computer. He showed me that Office, Internet and everything worked. Today I tried installing something and its asking for an admin password. I tried to get in touch with the seller, no trace of him and the cell number. What do I do? What if its stolen or something?
