Firmware package for an Apple MacBook Pro A1278, the 13-inch unibody model, compressed as a 3.78 MB RAR. The name does not state the logic board number, EMC code or year, and the A1278 covers several 820-xxxx boards, so the dump inside may not suit every unit. Such images are written to the EFI SPI flash with a programmer after board work or a corrupted firmware. Identify the 820 number on your board, read and save the original chip contents first, and check the image size matches the flash capacity.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
