If your Mac is in firmware recovery mode, the status indicator light rapidly flashes amber or is solid amber and your display may show a blank screen. You might need to revive the firmware on your Mac with Apple silicon or revive the firmware on your Intel-based Mac. If you still need help, contact an Apple Authorized Service Provider.
