    Default Macbook Air system lock and Efi unlock

    Any one able to advise on how to do this?

    It is a A1466 EMC 2559 model.

    ... and no it isnt dodgy, just the result of a spiteful act from someone whose ex-partner now has the laptop.

    Any help appreciated...

    Might be worth doing something like this mate:

    You just need a Teensy 3 board and then stick that program on it

    Don't format the hard disk before you do this or take it out - just do this and it'll be in within a couple of days from what that says!

    Another option is EFI chips from eBay but this is probably the easiest way.

    Thanks to reverend

    ive ordered the teensy 3.1 board, will let you know what happens. looks like the code is simply a keyboard emu that inputs the numbers via brute force...

    knowing which one works is captured by webcam...

    right, it worked.

    took me a couple of hours to figure out how to compile the code and load it on the teensy

    its basically a keyboard emu, 0001 <enter>, 0002 <enter>, etc.

    after a few hours it booted from the efi to the icloud screen, i was recording it with a webcam and saw the first numbers on the icloud screen, manually entered a few on the efi screen and boom, it worked.

    now on to the next problem... it boots straight to the OS utils screen.

    I need help (again) => [Only registered and activated users can see links. ]
