Macbook Firmware lock removal 2012

Firmware locks cannot be simply removed by removing ram or resetting something. There are two ways to remove a firmware lock:

1) Bring the computer to Apple with the *original* purchase receipt for proof of purchase (would work for the person who bought the MacBook in the first place)

2) Have the person you bought the MacBook from give you the firmware password so you can unlock the computer.

Unfortunately, there are no other ways of removing such a firmware password - that's the point of it.

Hi there, thomasrwborough!

Thanks for reaching out to the Apple Support Communities! It sounds like you’re having an issue with needing to remove a firmware lock from your Mac and I’m happy to help! I suggest taking a look at this article with steps to follow for How to set a firmware password on your Mac. Since you do not know the password for the firmware lock and have bought the Mac secondhand, I recommend you check out this section specifically:

If you forgot your firmware password

If you can't remember your firmware password or passcode, schedule an in-person service appointment with an Apple Store or Apple Authorized Service Provider. Bring your Mac to the appointment, and bring your original receipt or invoice as proof of purchase.

Take care!
