Firmware archive for the Apple MacBook Pro A1398 Retina 15 inch with logic board 820-00163-05, a 4.39 MB RAR. Apple uses 820-xxxxx numbers for logic boards, with the suffix giving the revision, so read the full number from the PCB before using it. EFI images like this are written to the SPI flash chip with a programmer to clear firmware locks or repair corrupted firmware. Dump the original chip first, since it holds the serial number and other machine-specific data that must be preserved.
