“If Mac Pro is in firmware recovery mode, the status indicator light rapidly flashes amber three times, briefly flashes amber three times, then rapidly flashes amber three times. This repeats until the computer is turned off. You might need to revive the firmware on your Mac Pro. If you still need help, contact an Apple Authorized Service Provider“
So, to be perfectly clear about this, they’re saying that if your Mac Pro, say, suffers a power failure during a firmware update and requires repair then it lets you know this by flashing the standard International Morse Code signal for S.O.S?
