You can get a working card on Ebay or Aliexpress - any MXM 3.0 card pulled from an iMac should be fine. 'Where can I get a card that works? (
I found out Apple uses special firmware and for a card to work it needs an EFI flash with Apple firmware.Ī card without Apple firmware will simply result in a black screen.Ī friend of mine did suggest I could remove the BIOS/EFI-chip from the original board and reflow it onto a cheaper card - but that will probably be too complicated for a lot of people and I already had a new card on the way.Ĭards that already have Apple firmware (pulled from iMacs) are interchangeable though - I upgraded from the 1GB 6970M to the 2GB version.
