No. Purchased from a family member when they upgraded to new Macbook. I've checked with them regarding a password or code. They confirmed they never would have set anything beyond the basic access password. In addition, if a password was set enabling this feature, I would not have been able to accidentally erase/reformat the hard drive or clone back to the hard drive, nor would I have been able to update the OS. Correct?Was your MacBook purchased directly from Apple?

How did you erase the drive? From recovery mode?Yes. They bought new.
So setting an EFI password is not easy or "accidental". I still don't understand how this happened.
What I was saying is "if" an EFI password had been set and enabled, I would NOT have been able to "accidentally" erase the hard drive, let alone "clone copy" to it back in January. I also would not have been able to upgrade the OS.
I believe you can boot into recovery and erase even with an EFI password.I didn't do the erasing, my son did it via Disk Utility thinking he was on his MBP, as they both looked identical at the time. He wanted a "clean" hard drive since he was having some issues. Unfortunately, he "cleaned" mine. No harm done as I have CCC clone backup. Neither of us had user passwords at the time. We do now!
I use TM as a backup too.
Command + r boots from the internal drive so an EFI password doesn't need to be entered if I recall correctly.Yes, but you would need the EFI password. I have never set one up.
Thanks. I learned something I didn't know before.Incorrect. Attached a photo of screen following a Command + R boot with EFI lockout.
Which Mac model & year did this unlock feature work on ?This exact same thing happened to me once, and I did solve it
I went into lost my device and lock it, they will ask you to put a password to unlock it, and that password worked as the firmware pasword.
Reprogramming the chip to delete the password is complex but not impossible, a professional can easily do it
