Does it have EFI Password or Activation Lock?
Activation Lock is the same as iCloud Lock on iPhones. Not sure if you could get around that.

how to read t2 chip

Re: Macbook 2018 above firmware password

macOS Catalina allows you to block the firmware from showing the seed that Apple needs in order to remove the password. Type this in Terminal: sudo firmwarepasswd -disable-reset-capability.

Hey Siddig, can I ask where or how you managed to find the uson chip on your model? I cannot find it any where on my board. it supposed to be a 4mb chip. my board is: A2141 820-01700-A
Thanks

Re: Macbook 2018 above firmware password

Hey Siddig, BTW, do not try unlocking it via the image. I unlocked mine using another mac. just link them both and then you can unlock them. now the reason I want to dump the image is because I want to modify it.

EFI is stored on the encrypted NAND chips and fed to the PCH by the T2.

Re: Macbook 2018 above firmware password

wrong wrong wrong! the 4mb bin its only thing you can do is change serial no unlock!
4mb bin you can read and manage with neo, if you have a good macbook and copy efi free bin to the same locked macbook dont work, also read locked mac and after unlock read again and compare and change is not working! activation lock is not only linked in serial!

ps the chip is a wson 2x3 1,8 volt

Re: Macbook 2018 above firmware password

Have you guys considered hijacking the iCloud dns and pointing it to a local server that is emulating the correct response to report that it is not locked just long enough to unlock it to disable secure boot?

Re: Macbook 2018 above firmware password

How does one go about this? I have a 16” in inventory and it be a blessing to learn how to do this!
