Efi
Hello,
Im new to this forum, and i've been looking around to find some help in regards my EFI issue that i've been having, and so this forum is the closes i could find to my issue.
A few days ago i performed a software update on my Mac Pro (2008 model) and after restarting, the computer would not boot! Infact the power button LED in front of the panel blinks non stop.
after quite a bit of research I found out that the EFI has been delete somehow!
So i took my mac to the apple store where the hopeless Genius guys told me that the logic board has been fried! but that didn't do it for me, so i started to do my own research and found out that the firmware that is housed in the EFI has been removed, now my computer does not boot. Infact the computer will not allow me to perform any startup keys. i wanted to reinstall the OS on t he computer by holding the mouse key so it would eject the cd, but nothing, i tried several shortcut ketys but it still doesn't respond just the flashing LED. no chime, no beeps nothing!
is there a way i can make a bootable USB or FIRE WIRE device that can house the EFI firmware so i can update the EFI, thats if i can somehow make the computer boot with any sort of ext. device?
can anyone please help me out here.
thanks
