If you or any of your users can't remember the firmware password or passcode, know that Apple doesn’t allow for any workarounds, but instead recommends scheduling a service appointment with an Apple Store or Apple Authorized Service Provider.

The process requires the original receipt or invoice as proof of purchase.Įarlier versions of macOS required manual installation of the firmware but, starting in 2015, Apple began bundling EFI updates with the macOS updates in order to deliver security patches to all users. But as security firm Duo Labs discovered in late 2017, some Macs aren't getting the right firmware, which makes them vulnerable to hackers. They recommend checking the firmware version and updating if needed. On Intel-based Macs shipped before 2011, the firmware password was stored in the PRAM and read by the system EFI firmware before other PRAM variables. That lead to a serious security issue, allowing the firmware to be revealed in a native macOS app and weakening the enhanced security Apple had hoped to introduce with the addition of the firmware password. In 2011, however, Apple added an important change to the system: the firmware password was moved to a separate programmable controller from Atmel. This component contains lockable flash memory to store the password and requires special programming with identifier numbers for both the Mac's motherboard and the Atmel chip to access and reset it.
Bypassing the Mac Firmware Password on MacBooks With Upgradeable RAM Since the controller is an independent component, the only way to bypass it is to manually remove it from the motherboard, but this requires highly precise reflow soldering tools and techniques. This hardware hack works on both Intel- and Motorola-based MacBooks and requires users to remove the RAM and reinstall it.
