"Anecdotal evidence has indicated that Mac systems also contain a “boot ROM”, which is executed before the EFI firmware and verifies the integrity of the firmware image including its cryptographic signature at the end of the firmware volume. If the firmware image is not deemed to be valid, the system generates the “S.O.S.” beep sound (literally “S O S” in Morse code) and refuses to boot."

Sounds like a great project!  I suppose the firmware you're talking about is contained on a certain chip in the Mac Pro. How do you know there is enough space on it to contain a driver ?  Is there any way to decompile the firmware ?

There is always room Grin

You can't decompile it, but you can extract it. UEFITool does a fare job, if you know how to use it, used to be a python script that did a better job of it.

Apparently the driver team works faster than the web team.

It always takes about a day longer for the web page for a given driver to go live, but it doesn't matter as everyone should be getting the driver directly from their auto-updater.  That is, once someone sees that a driver has gone live, you don't need to download it manually, just force an update check on your NVIDIA preference pane to get the new package.

I only get to use the autoupdate in the control panel for point updates between OS updates, which don't happen very often. I usually either screen share or ssh in to do the updates from a manual download. This time, I had a kids clamouring to get on the computer so I took a stab at the next version number.

I'm looking at ways to try and hack Apple's firmware updates to insert a NVME driver into the Firmware of a MacPro so it will boot from NVME drives.

Just taking a quick look at the firmware update for the 5,1 from High Sierra installer, the firmware seems to be locked, I can't insert anything into it with UEFITool. This shouldn't come as a shock, as the file name is: MP51_0084_00B_LOCKED.fd

If others are interested in this project we can look into it more, and see if we can't figure out how to insert a driver into the firmware, but then I'm sure Apple's firmware update tool won't flash a modified firmware unless it has a proper CRC, so we'll have to overcome that too.

Since this OS update do not require restart. So I tested it with my theory that we can install web driver without a flashed card / screen sharing / another GPU assist. The result is success.

The procedure as follow.

1) For normal OS update, running "sudo softwareupdate -I -a" should able to update the OS WITHOUT reboot (same as the security update this time)

2) After update, the OS version will be changed WITHOUT reboot (you can confirm this in system report)

3) Install the new Nvidia web driver accordingly

4) The installer will show you the warning about OS version not compatible and fall back to Apple driver.

5) let the driver finish installation, do NOT click restart

6) Open terminal, and enter "sudo nvram nvda-drv=1"

7) Open web driver manager to confirmed web driver is selected.

Cool Reboot



With the above procedure, the cMP will restart with web driver installed, selected, and display everything properly at the 1st reboot. No black screen, no need to use screen sharing (or using EFI non accelerated display to do anything).

N.B. The above procedure is used with BOTH SIP and Gatekeeper OFF, I am not sure what will happen if you have any of these function ON.
