How to build your own iMac Pro [Successful Build/Extended Guide]

o.k. don't be surprised if nearly nothing of your original EFI-Folder remains ...

New EFI-Folder attached below.

Things you still need to do:

1.) Complete again serial, board serial and SmUUID in your config.plist.
2.) Enable the two 1GB Ethernet onboard controllers in your BIOS
3.) Make your GC-Titan Ridge appear under macOS and especially in your IOREG (it should be implemented under PC03.BR3A.SL09 without any TB-SSDT). Did you properly define in your mobo BIOS TB settings that the GC-Titan Ridge is in PCIEX16_4?

In case of any issues I need again an IOREG.save of your system with the new EFI-Folder and a 'PCI' snapshot of Apple's system report.

Today it might be already too late to do anything else.. If you want, we can continue sometimes tomorrow.

OK, it still boots

I have implemented step 1&2. Please see attached IOReg file of the new setup.

I do not see TB3 in system profiler, so something might still be wrong?

System profiler?

There is no IOREG save attached to your recent post ..

TB controller must be visible in IOREG. Otherwise it is not seen by macOS and it will also not appear under ‘PCI’ of apple’s system report.

That’s meaningless.. TB drivers never will be loaded but TB adapter must appear under Section “PCI” and in IOREG.

And that's not the case, neither in your actual IOREG nor in Apple's system report I guess. You need to make the GC-Titan Ridge appear under macOS.

Hi @kgp

I've noticed that you recently changed your GPU from your older GA Vega 64+ OC Gaming to a Sapphire model. As I found a nice second hand GA Vega 64+ OC Gaming, would you be so kind to repost your dedicaded SSDT? Thanks!

OK, I have followed the Thunderbolt tutorial on page 1 of this thread.

Results:
- Thunderbolt is present in Windows, Port 1 and Port 2
- All BIOS entries have been copied and applied in BIOS according to page 1 of this tutorial
- TB3 card is not visible under PCI entries:



What shall I do next?

What about IOREG?

SSDT-X299-Vega64.aml of the repository is the one I also use for my air-flow Nitro+ Vega 64, if this is what you are asking for.

Hello
I think I need Help for the Alpine Ridge SSDT implementation
I try to modify the SSDT-X299-TB3HP.aml without success.
Any Help would be appreciated
Thanks in advance
