The Matt Card represents an alternative to shipping your computer to us for unlocking, or swapping the EFI ROM chip on your motherboard. It plugs into a tiny connector on the motherboard. As long as the Matt Card is plugged in the (unlocked) ROM on the Matt Card will be the one that is used.
As you can see by the photos, installing the Matt Card is simple. Turn off the Mac, plug in the card, turn on the Mac. Done.
There are Matt Cards for most models of MacBook Pro retina, MacBook A1534, Mac mini and MacBook Air. You can check below to see if we make one for your model.
Please note that you must order the Matt Card that matches your model EXACTLY. There is a restocking fee of $20 for returning a non-defective card. If you have any questions please Contact Us before you order.
