Firmware dump for the Apple MacBook Air model A1370 from 2011 with the Core i5 1.6 GHz processor, identified by EMC 2471. The 3.75 MB ZIP likely contains an EFI boot ROM image for the SPI flash. Technicians write such images with a programmer to revive a Mac that will not chime or boot, or to clear a firmware lock. The EMC number on the bottom case should match. Save the original ROM before writing, since it holds the serial number and other machine-specific data a clean image lacks.
