What Is EFI firmware password protection on Apple T2 security Chip?
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.
Apple released EFI updates separately, but since 2015 the EFI update is bundled in the software update Apple has been pushing out to users. However, if you are running one of the 16 Mac models identified by Duo Labs, there is a chance that your system hasn’t received any EFI update at all: iMac 7,1 to 10,1, MacBook 5,1 and 5,2, MacBook Air 2. Firmware Update Procedure – USB method (Mac only) Document No. 480SSD‐SFUSB.A00 09/02/14 Page 4 2. Insert USB drive containing bootable.dmg contents. Hold the “option” key down and power on Mac system. Wait for the “EFI boot” option to appear, release the option key and then select “EFI boot” to continue. Download kodi application macbook pro.
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.

Macbook Pro Efi Firmware Update 2.2 Download
Apple on Thursday evening released an EFI Firmware update for the latest iteration of its MacBook Pro notebooks and also issued a new version of its Firmware Restoration CD for use with all Intel-based Macs.
MacBook Pro EFI Firmware Update 1.3 [1.8MB] fixes a display issue on 2.2/2.4GHz 15-inch MacBook Pro models, which were released last month.
Apple said the update requires MacBook Pro Software Update 1.0, but otherwise provided no further information on the release.
Firmware Restoration CD 1.3 [22.5MB] can be used to restore the firmware of an Intel-based Macintosh computer. However, Apple says the CD can only be used to restore the firmware after an interrupted or failed update.
'If your computer is already in this state, you’ll need to download the software and create the CD on another Macintosh computer, or you can take your computer to an Apple Store or Apple Authorized Service Provider to restore your firmware,' the company advises. 'This CD can be created on both PowerPC- and Intel-based Macintosh computers.'
