It seems like he Gigabyte boards use the same 156c TB as the Macbook Pro 11,2. Is it possible that a ID change at the DSDT or Clover level would be applied earlier in the boot process than fakepciid?

You could try it. But I'm not sure how to construct the Device in DSDT (for _DSM method). And there is no Clover support for that. An EFI property string might work (if you can figure out EFI Studio) and if Clover does it correctly(?).

This does show that the binary has a reference to device-id:
Code: 
MacBook-Air:Extensions Admin$ strings /System/Library/Extensions/AppleThunderboltNHI.kext/Contents/MacOS/AppleThunderboltNHI |grep -y device
device-id

A config.plist patch to the binary might be easier to implement. Do you know x86 assembly?
 
No unfortunatley, I only know a smattering of c++. Initially i had
looked inside all the TB kexts to see if one contained a .plist with the device id's, but i didn't see any.
I don't suppose a hexedit is possible? Thats about the limits to my hack skillz.

thanks

I wasn't asking about C++, but if you don't know C++ there is little chance you know x86 assembly...

A hexedit or config.plist patch is something you do after you have determined what code needs changing.

Hang on a bit... I have an idea...

Thanks! I'll give it a shot tonite. I changed something on in my bios that corrupted my osx installation, so i'm working now to get yosemite back.
 
Aright, I'm back up.

I have some sucess to report, using those latest kexts the device ID of this TB device is reflected as 156c (Vs. 1566) under Hardware -> PCI -> Expresscard (System Information).

The Apple Thunderbolt->FW800 adapter is still unrecognized (and thus any attached peripherals), but I think it's still a really good sign. *I think even on Gigabyte boards using a native 156c TB pcicard (same as mbp), it appears under PCI vs Thunderbolt, requiring additional work to make it appear as native/internal.

Attaching latest ioreg & system log.

*I should mention that these latest kexts killed the fakepcid for the hd4600, i needed to remove my Intel GFX kexts to boot.

Thanks!

The updated injector did what I thought it would (change the device-id), but no real progress though....

I probably should have provided the updated FakePCIID_HD4600* kext. If you want to fix that, see here: http://www.tonymacx86.com/yosemite-...ngff-work-yosemite-post985467.html#post985467
 
Hello, I have a question for you. ¿How did you got ThinkPad W540 working? I have the same exacly laptop. ¿Could you share the EFI partition or Extra? I will be very appreciated. Thank you
