Removing a Mac's Firmware Password By Reflashing EFI ROM

According to Apple, the only way to remove an unknown firmware password from a MacBook (2011 and later) is to take it to the Apple Store with the original proof-of-purchase. However, I've found that there is another way, which I've been successful with for the unibody MacBook Pro--it's essentially just modifying a couple bytes in the EFI ROM, which should be simple. What's not simple, however, is figuring out how to read and write to the EFI chip. In this post, I'll talk about the process that I figured out and what worked for me.

The Official Method

Apple's method of resetting the firmware password is not reproducible, as Apple generates an SCBO file that unlocks the EFI using their private key. You can read more about this process here. The problem with this system is that, if you are in the unfortunate situation of neither having the firmware unlock pass
