Firmware Password Lock after Bootcamp Install

macos password firmware bootcamp recovery

Solution 1:

No - Firmware Passwords exist to prevent any non-approved boot methods and prevent you from bringing any other boot to the system.

It's like putting superglue in a deadbolt lock and only having the small lock on the handle. If the small handle (your normal OS) breaks - you can't get in by bringing another small handle - you need to release the deadbolt (firmware password).

Open a case with Apple Support to see if your firmware lock can be bypassed locally or you need to prove you own the Mac and have apple generate a rescue key.

A firmware password prevents starting up from any internal or external storage device other than the startup disk you've selected.
