Hello there, I am dealing with the exact same issue here. I suspect apple tempered with efi files which are being downloaded from websity by the tool to obstruct updates. I got a hint which unfortunately I didnt try - the solution is to run the flash from old osx tiger system.

I had similiar issue on my mac pro 4.1, I have updated hundreds of them from my yosemity osx disc but not this time, the solution was to run the tool from old snow leopard osx and it worked like a charm thats why maybe the solution to 1.1 will be similiar.

Hopefully there will be a new one released, compatible with 17G4015. I gave up hope for Mojave...

He mentions getting the Dell 1GB 6770M working with a modded VBIOS, but nothing about the 780M.

Does anyone have modded VBIOS for GTX 765M and/or 780M that gets the thunderbolt ports working?

The Web Driver 387., pulled by Nvidia works fine for the High Sierra Security Update 2, build (17G3025).  I saw a reference to that on another site.  This morning I cloned my boot drive, and tried it.  And it works just fine!

The old Web Driver is still working with Security Update 003, Build No. (17G4015).

Seems like Duke already got the GTX 660M and GTX765M working on the A1312 iMac based on this Louis Rossmann stream:

Check a 2:08:00, he's talking about it.

Did Rominator fall off the face of the earth?

I joined this old thread because I've just purchased a second-hand HD7950 Mac Edition but I am having severe troubles in outputting a VGA signal (via DVI-I / VGA adapter).
If the VGA is the only monitor connected I can happily see the boot menu and the OSX progress bar until the moment the desktop should appear. But then, nothing, the display went off.
If a second display is connected either to HDMI or one of the miniDP port, the priority goes to the digital video out for boot menu but nothing is displayed on the VGA monitor.
Changing the video settings for the VGA monitor on the Control Panel didn't help at all, the monitor remains black.
Today I have also tried a DVI-D / VGA adapter (yes, they exists) and I had partially a success, one of the two adapter I purchased show the video signal on the VGA but it does not remain locked, I think because the converted analog levels are too low to be stable enough for my analog monitor.
The question is: has anyone experienced this issue on his Mac Edition card? Recently I have also flashed a Reference 7970 card using the "bundle" method and every video out port works as it should (including the HDMI) but the VGA part of DVI-I port has the same issue of the HD7950 Mac Edition.
This behaviour happened also before the BIOS flashing (using the video card unflashed in OSX environment) so I think it is not really a Mac firmware issue.

Any idea or suggestion will be greatly appriciated, maybe a different DVI-I / VGA adapter? For example the Apple adapter (the white short cable) show some signs of life while the common ones with connectors tied in melted plastic tends to show nothing. Of course on BootCamp side (Windows 7) everything works, no surprise here...

I successfully flashed my own cards for two macs, 7950 and 7970 Gigabytes.  I tried flashing a friends 7850 2gb Saphire and all seemed to go well right up to the boot screen that actually did display.  I suggested he find a Saphire card with two mini displayport outputs.  I got the correct device ID and patch showed successful.  Then when the OS was supposed to show up, black screen.  Screen seemed to get caught in a loop, the monitor showed the source every few seconds but just black and no boot.  Does anyone know why?  I tested all ports on a Samsung 1080 monitor booting Mojave.  Thanks for any hints.

I am not sure

I noticed the original bios is Pitcairn.  Has anyone gotten Pitcairn processors to work with the script?  What needs to be changed?

Unlike the other cards everything after 64,000 is 0's in the hex editor.  Does this mean it's a PC bios not UEFI?

The device ID is 6819.

I've attached my original bios and the modded one that does show mac boot screen then won't work in the OS.

Any hints?  Thanks
