Matt Cards
The Matt Card is the alternative to 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 (it has to stay plugged in...) the ROM on the Matt Card will be the one that is used. Using the Matt Card is simple. Turn off the Mac, plug in the card, turn on the Mac. Just make sure you order for exactly the right model of Mac! The wrong model will never work.
A Matt card does not solve any NVMe/sleep issues. But you can read and patch your ROM and send us the modified dump immediately before or immediately after ordering a Matt card and we can write your dump onto your Matt card.
Price is 65 Euro single piece including shipping world wide. We ship everything registered (signed for) and priority. Tracking is available on all our shipments.
