![]() ![]() I tried burning the Firmware restoration onto a CD from here:īut the computer did not respond the way it said it should (with the 3 flashes/beeps etc.) and have the optical drive open for the CD. This software is not supported on your system.īut clearly this is the correct EFI for my computer. I downloaded the EFI update from the apple website from here : īut everytime I download it, as I click to install, it gives me the message: I need to update the EFI firmware on my 8 core mid-2010 Mac Pro.
