Brand new pre-programmed EFI Bios chip. 100% working and confirmed with clean ME Region.
The EFI Bios chip can be used for the following:
– Fix Corrupted Firmware caused during updates. – Remove iCloud Lock (4 or 6 Pin Code) – Remove Mac EFI Password Lock, Unlock Disabled Mac. – Solve MDM ( Mobile Device Management), DEP (Device Enrollment Profile)
Please add your laptop serial number in the serial number field if you like to retain your original S/N.
NOTE: (Do not use your original serial number if your Mac has MDM or DEP Profile) Chip will come with a different clean SN.
(It will NOT remove the Operating system password or Hard Drive password)
Professional soldering skills are required to replace the chip. Please be careful to not damage any components around the chip.
We are not responsible if you damage your logic board.
If you don’t have soldering skills, we recommend checking our Solderless EFI Chip. It does not require any soldering or removing the old chip.
After installing the new chip is highly recommended to erase the disk, and then reinstall a clean version of macOS.
Please select the correct EMC model or motherboard number. The EMC number is written on the back cover of your Mac, or you can find the EMC number by visiting this website.

EFI Chip Location/ Installation
Installation:
Please make sure to follow the pin sequences; there is order on the pins. The small dot on the chip is PIN #1. Make sure to check the position of the old chip and solder the new chip following that order.
Reset the PRAM after installing the new chip
Turn on your Mac and hold down all four keys at the same time. “Command” + “Option” + “P” + “R”
Keep holding down all four keys until you hear the startup sound for the second time.
Reinstall a clean version of macOS. (First, erase the hard drive using Disk Utility and then reinstall macOS)
For older Macs that need a physical BIOS Chip replaced to unlock, unenroll, and change password – this will work well. You do have to desolder the old BIOS and resolder a new BIOS but if you don’t have the facilities, you can send in your Mac and they will professionally install the new BIOS. Cost is more but worth not having to destroy a main board due to soldering. I have used this mail in service 4 times and have had older 2010-2011 Macs replaced out. Perfect service and they can even retain your old serial number!

I have a MacBook Air 2012, I no longer remembered the EFI password, I had to change the ssd and for not remembering the password it had been stopped for years. Here in Brazil there is no company that does this service. I bought the eprom and changed it, my mac came back to life.
