I was trying to enable guest account in Mac. When clicking guest account in login screen, the Mac asked for a restart to enter Safari only mode. I have selected yes to restart and the Mac now asks for firmware password after restart. How I can skip this and go back to the old login screen again?

Additional details

In the Mac, these are enabled:

  • Firmware password
  • File vault

OS : 10.15

Accidentally, I do not remember the firmware password :( and I want to go back to the old login screen.
I suspect that the Mac is now trying to boot from some other startup disk for Safari only Guest mode?
Is there any way to go back to the original startup disk, which will not ask for the firmware password?

  • A normal reboot didn’t require the firmware password?

  • Yeah @nohillside, I think a normal reboot shouldn't ask for it. I don't know why it is asking for firmware password?

There is no going back. You have to enter the firmware password. Or you can reset it by going to Apple store https://support.apple.com/en-in/HT204455
