![]() 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, 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.

![]() 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 |

![]() 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?
