@codemonkeymike is there a way in your experience to extract the hash of the firmware password from the chip via SPI bus or similar ? Then run hashcat on it. It’s excessive for sure, but maybe a solution can be devised somehow. Extract some hash or firmware and find an exploit or something and find a working solution eventually. In the end the chip is an oracle and something is verifying the firmware password which has to be stored in memory.

@codemonkeymike did you try https://theapplewiki.com/wiki/Checkra1n their site says they have experimental support for T2 processors.

@codemonkeymike I am interested to see if you have tried this method
https://mrmacintosh.com/how-to-restore-bridgeos-on-a-t2-mac-how-to-put-a-mac-into-dfu-mode/
And
https://mrmacintosh.com/how-to-remove-mac-firmware-password-new-way-if-you-have-a-2018-2020-t2-mac/
You need a second Mac that works and you control the one with a firmware lock using Apple Configurator. I have converted Apple Macs to run Linux but all of them have been 2017 or earlier.
