I'm firmware locked out of an OS-update bricked Macbook 2019. I wouldn't care if the OS booted, I don't need the firmware password to use it, only to wipe it. I don't really want to wipe it, I want it to boot. I bought it with cash in Grand Central. I have my welcome to your New Mac email from the week they launched and it's in Find My still today. But I didn't keep the cash receipt and I password protected the firmware before an International trip, and don't remember that. Apple will not unlock it, though it's in Find My, and has only been mine for its entire history. (They also won't unlock it, fix the bricked OS update, and lock it again, which would be fair enough. But as I see it, they broke my machine, and they prevent me from unbreaking it.) So FindMy won't save you from yourself. :-/
