EFI Firmware

The EFI (Extensible Firmware Interface) is the interface between the firmware and the hardware and the operating system of your computer. It is the successor to the original BIOS motherboard. The EFI interface was developed by Intel with a focus on the use of Intel 64bit Architecture (Intel IA-64). In addition, a graphical interface is integrated and thus simplifies operation.

Most firmware updates on Mac computers are automatically installed when updating the OS X operating system.

You can verify the EFI Firmware Version as follows:

  • Open the system information of your device
  • Under "Hardware" you will find the model information, boot-ROM  version and SMC version of your device


The Bios chip is programmed and verified with the latest bios.
