    hello
    i bought 2 laptops off CL -one of which was a 15" 2012 macbook pro retina.

    When i turned it on, it booted to the icloud page requesting the pin. then booting with the option key pressed required the efi pass
    i thought maybe by formatting the drive and cloning another i can bypass that.
    so i got an external flash drive enlcosure, connected to another laptop and repartitioned and cloned the drive.
    now when i boot i get the ? folder.

    i also bought the teensy kit, but i dont know how to use.

    any suggestions i would really appreciate.

    Sounds like the EFI password is set. You should return it to the seller to sort out. If they cannot, then the legitimacy of the sale needs to be questioned.

    This guy not only stole the laptop, but he stole money from you. You probably have some information the police can use to catch this guy. Also, if the computer is booting to the iCloud page, then it's rightful owner already reported it missing to Apple, so there's a chance everyone can get what they deserve: you your money back, laptop back to the owner, and charges for the sh*thead you bought it from.

    Good luck.

    there existe multiple methods for removing efi protection including code counters, bios reader/writers, and special files for formating, all it takes is some time on google
    im not one to support theft but where theres a will theres a way
