Sure, a dock can be used. Most but not all Thunderbolt 3 docks have two Thunderbolt ports, where one port connects to computer and the other is used for daisy chaining. If buying a dock, always check that it has a second Thunderbolt port (with the lightning logo).

thanks if want to use a pci/thunderbolt card is there one that works ?

@qthegaijin,

Very interesting post!!
  • Which tool did you use to flash the GC-Titan Ridge?
  • If you used a CH341A programmer, did you connect Pin 28 to 3V3 (Pin 2) of the AMS1117?
  • MacPro 5,1:
    • DSM2.Hackintosh is working on a modification to the Thunderbolt SSDT.
  • Gigabyte Z170X Designare:
    • The screenshot of 10.12.2 at RP05 does not actually show full Thunderbolt Bus. It does show that Thunderbolt is working in ICM mode (Intel Connection Manager).
      • I assume that the on-board Alpine Ridge firmware has not been patched? Is that correct?
    • If the Antelope Audio device works fully under Alpine Ridge with 10.12.2, then I'm curious why it fails with the same Alpine Ridge under 10.12.6?
    • I didn't realize that this motherboard has an on-board Alpine Ridge controller and a Thunderbolt header (THB_C) for an add-in-card! How nice...
    • With the modified firmware on the GC-Titan Ridge, your screenshot clearly shows Thunderbolt Bus, so it's good to see that it works when (a) connected via THB_C and also when (b) pins 3 and 5 are jumpered.
      • Do other TB3 devices work fully?
      • If you have a Thunderbolt 3 dock (most of them have Alpine Ridge chips inside), have you tried connecting the dock to GC-Titan Ridge and then connecting the Antelope device to the dock?

** Native NVRAM in Clover **
...
I have followed this guide closely to activate NVRAM on F9b bios.

Problem is - when trying "sudo nvram -p | grep TestVar" in terminal, it doesn't return anything. Guess that means NVRAM isn't working, right?

Are you running OsxAptioFix2Drv-free2000.efi or the newer OcQuirks/FwRuntimeServices? Please check CLOVER/drivers/UEFI folder.

I may have to update the NVRAM guide... Please try switching to OcQuirks-4/FwRuntimeServices as explained here:

Your inquiries suggest you want to add additional Thunderbolt ports, not simply daisy chain.

First, understand that a Thunderbolt dock will NOT create additional Thunderbolt ports.
It will add other ports (USB3, DisplayPort, ethernet etc.), but at best, will only allow additional daisy chaining from the original port onto more devices.

Adding a PCI Thunderbolt card to provide additional Thunderbolt ports would require a TB header on the motherboard.
The Gigabyte Z390 Designare does not have an TB header available.

I don't believe there is any way to add additional TB ports to this motherboard
