Efi chip location Macbook Retina 12'' A1534 was created by Bigwezel

Hello.

I just received a Macbook Retina 12'' A1534 with efi password lock. I opened the Macbook and got the logic board out. To my surprise i can't find the chip that holds the efi bios.

Does anyone have a clue which chip holds the efi bios?

In the attachments you can find hd pictures of the logic board.

Thanks in advance.

What year is that model? Gotta be a 2015 model which has the new BGA.

If I helped you buy me a latte!

I think on this model they actually went with the BGA style EEPROM, so we are still looking for a 25 series chip with a different identifier possibly.

If I helped you, buy me a beer!!! Happy Hunting...
