how to remove firmware password on macbook air

In the mess of computer parts, I found a 2012 MacBook Pro A1286 that was missing its battery, memory, and hard drive. However, the student whose basement had been formerly used for the organization had graduated, so all the hardware had been moved to the new location. The non-profit took donations of computers and refurbished them to be donated to families and other students without computer access at home. I was volunteering for the non-profit he ran. I was recently at another TJ student's house helping organize his basement full of computers and computer parts.

For instance, one commenter on a thread I read explained that a family member had gifted the system to them, but no longer remembered the password nor had the receipt, leaving no options to reuse the computer.

Many threads on the Internet show that this situation is often not a result of theft, however. This is understandable from Apple's viewpoint, as it can deter theft once the Mac is stolen, the thief cannot reimage the computer, making it useless. The problem with this system is that, if you are in the unfortunate situation of neither having the firmware unlock password nor the original proof of purchase, you have no other options. You can read more about this process here. The Official MethodĪpple's method of resetting the firmware password is not reproducible, as Apple generates an SCBO file that unlocks the EFI using their private key. In this post, I'll talk about the process that I figured out and what worked for me. What's not simple, however, is figuring out how to read and write to the EFI chip. 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. Removing a Mac's Firmware Password By Reflashing EFI ROMĪccording 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.
