Hi! my dilemma is I bought a 15" retina Macbook Pro from Craiglist. I told the guy that was selling it that I would need to see it boot up and make sure it wasn't locked(EFI and/or ICloud), he agreed to do that. Whenever me met he said that MB Pro's battery had died, and so evidently there's was no way for me to verify if it boot up and was unlocked. I told him I couldn't buy it like that! but he said he really needed the money. So he asked me much I offered to take it like that, and he agreed for a little more of what I offered. We made a deal. Went straight to Best Buy to buy a charger, when I got home I plugged in and turned on, it was Icloud locked. I immediately contacted the guy and asked him why was it locked and if it was stolen, he denied it was, so I asked him for the password to unlock it but he never replied back. I don't know if he locked himself in regret of selling it at such a low price or if the real owner did in case it's stolen. I had the MB unlocked and I'm able to get into OS, I just don't know if whoever the owner was(seller or someone else) is dissociated from it? I don't know what to do here.
