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

Suggestion for those experimenting with the Titan Ridge PCIe card: when re-booting, try: completely shutting down instead of a "hot reboot". Which means: do a normal O.S. shut down, then power off using the PSU rocker switch, then press and hold the case front power button switch for several seconds, in order to discharge the PSU's capacitor. Then power on again, first using the PSU rocker switch, and lastly power on again using the case front power button switch.
At least that way, possible effects of a latent system electrical charge on the Titan Ridge card can be discounted.
Statements have been made that "initializing the card while running Windows" is something important to do.
Maybe doing so leaves a latent electrical charge on the device? And that completely powering off & shutting down would remove that latent electrical charge.
Anyway: something to think about.

Good point!

With the GC-Titan Ridge once working under Windows, one could also reset NVRAM with F11 in the Clover GUI, if there are any persistent issues under OSX.

So I've made some progress after reading in the eGPU forum that someone got it working just fine on an AMD machine, that didn't even support TB to start with.
With THB_C cable disconnected et TB3 disabled in the BIOS, I can reliably see the devices in the thunderbolt utity. Can hotplug just fine. However, none of those devices are functional. They don't even appear in the hardware manager.
It shows that the TB3 needs permission, which I have set. It's 2AM here, will continue tomorrow

You could try procedures proposed in posts #10658 and #10659.

The advantage of the GC-Titan Ridge is just that usually one does not have to unplug the THB_C for achieving TB and UCB-C HotPlug under macOS and therefore one can use the adopter under both Windows and macOS without restrictions.

You did not answer on my reply and on the SSDT I prepared and attached for you in post #10598....

What happens when nulling ANS2? Did the attached SSDT work?

Please comment and answer before requesting further help and try to provide a DSDT.aml of your system!

This is already the third time today that you post the same content and request!

Thanks, somehow I missed that! I tried the modified SSDT in post 10598 but it didn't have an effect. Attached is my DSDT dump from clover.

Thank you!

Thank you!

Please upload also your EFI-Folder. And just in case, please upload also an IOREG.save of your system.

You must have somewhere a PXSX to ANS2 replacement in the config.plist or some SSDT, which must be removed.

I am willing to help.

Note that unless you gain the following TB ACPI implementation (outlined in red),

the TB SSD is not implemented at all during boot. Not necessary to mention that it makes of course no sense to perform any testing of an incomplete and faulty TB implementation.

Has anyone fully transitioned to Mojave as a daily driver?

How's the stability from 10.13.6 > 10.14.0?

High Sierra 10.13.0 was a mess for me.

I've put back the Alpine Ridge card, like @mm2margaret, I've better things to do.
I would have continued to try to get it to work if my Thunderbolt screen worked first go, or at least displayed video rather than stay blank.

That's what I feared...
For the moment I will stay with my Asus TB EX3 witch is fully fonctionnel.

That my GC-Titan Ridge works flawless including TB HotPlug und USB-C HotPlug even with THB-C connected is not a legend that I distributed for fun.

Sad that some people are not able to set their things as required and moreover scare others with their comments.

Anyway, everybody's decision with what to go for..

Yes of course I know that in your build it works flawless and I will wait for other perfect achievement on others builds.
