I recently purchased a mid 2014 macbook pro 15″ with retina display at craiglist. After i got home i try to reset the hard drive to new condition. After i clear out the hard drive and restart the computer, it ask me to connect to internet which i did and it was loading up. Soon after the bar loaded, the system restarted.When the computer boot up, it have a folder with a question mark flashing. And when i press command R on the next restart, it show a big lock with a box that i can type in something. Therefore i believe i bought a non legit macbook pro. From what i read your website, i believe my new macbook is locked. I see you provide service to unlock the macbook back to normal, but is it guarantee to work and keep working on the future?
Thank you very much
