What Is EFI firmware password protection on Apple T2 security Chip?
How to Unlock MacBook Air’s USB and Use it As Regular USB July was the month in which Apple released Mac OS X Lion through its Mac App Store. Later on this new OS was also released in USB flash drives which costs $69.99 whereas the downloading of OS X Lion from App Store costs you only $29.99. I was working on my macbook air and pressed some keys trying to close a window and suddenly, the keyboard is locked. I cannot key in any key. Even my password.
Before you use Mac EFI unlock service, you should learn what EFI is and how this passcode protection works on Apple devices with the T2 security chip.
EFI stands for the Extensible Firmware Interface. By this abbreviation, you can guess that the EFI firmware passcode is not the same thing as your regular computer password used for logging in or Mac Activation Lock. Your computer's operating system bootloader is contained in the EFI. This system partition also includes your hardware's driver files. Every time a macOS device boots, it uses the Extensible Firmware Interface right before booting.
As your computer is booting, it uses the memory-mapped from the T2 security chip to fetch the UEFI firmware. UEFI stands for Unified Extensible Firmware Interface. Users choose to enable the EFI password on T2 computers to protect their devices from untrusted firmware loads during startup.
The problem comes when a user wishes to reinstall the operating system on a Mac computer, erase the hard disk, repair, or restore the device using Time Machine. During such a recovery, users often come face to face with the protection through the EFI firmware password.
In other words, if a current user or previous owner has enabled the EFI password feature in Security Boot Settings, the macOS computer will stay protected. The device will keep asking you to enter the EFI firmware passcode during startup. It will not let you choose the startup from a storage device. You will not be able to get to macOS Recovery or add modifications to the computer. Once again, the protection through Mac EFI firmware password only works on T2 devices.
Suppose you cannot recollect this passcode. In that case, your only chance to use Mac as usual and enjoy all macOS features is by getting Mac EFI unlock service.
