Accessing daughter board on Mac Pro

Can you get to the daughter board with out tearing down the whole mac?

Update (03/03/2018)

Hi Dan,

I have a Mac Pro 2013 that I want to do a clean install on the but the Mac is EFI locked.

I have read that the only way to get the code is through Apple and you have to have the receipt which I do not have.

I've been in touch with a guy who can create a Matt card but I need to access the round PCB (daughter board) as there is a small socket which will house the Matt card. The Matt card will somehow bypass the EFI code. I've managed to access the board by following steps 1 and 2 and 10 and 11, it says that the two screws that are on top are t7 but they're actually t10.

Getting to the daughter board was simple and straight forward.

Can you explain what you mean by daughter board? Can you tell us what the problem is. The more you can explain, the better we can answer.

Have you spoken to the original owner of the system? He should be able to give you the hardware password to you can unlock the system. If you can't get that you got a stolen system! I would get your money back.

Other than replacing the EFI chip there is no means to bypass the EFI. The Matt board leverages the diagnostic port the laptops have. The Mac Pro uses a very different design (slot in middle) as far as I know there is no EFI override tool. Even still, if the original owner also iCloud locked your system you'll have problems with application access from the Apple Store.

@fiftydong how did you unlock it?

@mayer - he used a device that plugs into the diagnostic port its call a Matt card. It appears this guy has just produced one for the Mac Pro.

@danj got a link to that? I took my 2009 from 4,1 to 5,1 doing this: Installation of High Sierra 10.13 on unsupported Macs But if I boot from a hard drive using an external drive with High Sierra on it, it wants to flash the EFI again. I did install Sierra after my third party flash but I'm now afraid to run the Apple version (don't want to loose my board ;-(
