Firmware image for the Apple MacBook Pro A1708, EMC 2978, logic board 820-00840-A, with the Management Engine region cleaned according to the name. The 8 MB binary matches the SPI flash used on this board. A clean ME image is used when the existing region is corrupt or carries data from another machine.
