How to extend the iMac Pro to X99 [Successful Build/Extended Guide]

[kgp]

Yeah, I know, but thats the only way to achieve Hot Plug isn't it?

Thanks!

To return to Windows after removing the THB_C is the best way and only way to screw up the entire TB System!
Never return to Windows with THB_C removed!

The proper approach is to make your TB adopter work under macOS with the THB_C connected! Once all is set and working properly, remove the THB_C for hot plug functionality and never return to windows with such TB configuration!

It is that simple, man..

Just wanted to say thank you KGP for your guide! Successfully applied it to my system months ago and have been enjoying it ever since. For those with a system similar to mine, I can post my EFI folder.

Cheers!

Board X99A II, with Nvidia 1060 Ti here. Files I used include your SSDT iMacPro for Nvidia and everything is working great, but there is a problem so far:

USB ports report an error in waking from sleep: the classic message "Disk not ejected properly", is this behaviour expected? Or am I missing something here?

That's a remaining bug without solution.. if you find any, please let me know..

Yes, I found this: https://www.stclairsoft.com/Jettison/ it's a paid app but it automates the process pretty well ... and it works with USB ports from TH3 too.

I will give this a try, thank you so much, as always!

Thank you very much for your guide, I have succeeded. I have ASUS X99A II (unlocked MSR), gtx1070, I7-5820K. I changed the FakeCPUID using your config, but found that I can't load XCPM, maybe this is the difference between Haswell-E and Broadwell-E. I have tried it for a long time and it didn't work. Finally, I found that using kernelXCPM can load XCPM.Without your extended guide, I can't install it smoothly. thank you very much! ! !

@Lai, please add your system specs (mobo, CPU, GPU) to either your profile or signature ..

All the best,

KGP

Thanks a lot KGP !!! I just managed to install High Sierra 10.13.6 and everything seems fine.
Like Lai i had to use "kernelXCPM" to load XCPM.
I tried OC (manual) from 3.0Ghz to 3.7Ghz and everything stills works.

ASUS X99E-WS
i5960X @ 3.7ghz
Nvidia TITAN X

Little Update: I added an Asus Thunderbolt EX3 card to the system (X99A2, Intel i7-6850K, Nvidia 1060 Ti) and I added the SSDT-9---.aml to the Clover folder as per @kgp instructions. I report this:

• if I connect the TH cable to the motherboard, everything goes fine and Thunderbolt 3 seems to work properly but the sleep is broken!
• if I do NOT connect the TH cable ... Thunderbolt card is not recognised by the system.

Any hints? TIA!

PS: of course I carefully implemented the instructions as per E.7 and E.9.3 sections of this guide and the TH3 card is in PCI slot 4. ..
