[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

ok, disable VT-d in the BIOS and try it with this.
This helped with my ASUS board as I had some difficulties there as well.

...this is only cosmetic and can be changed or deleted in config.plist

Your are quite right that PC00 should be used instead of PCI0. The system should not crash when using PC00. Attached are modified versions of the (a) simple and (b) complex versions of the Thunderbolt SSDT. As before:
  • Simple --> must disable the two ACPI patches (SSDT-TB3-Designare-X299-EX.aml)
  • Complicated One --> must enable the two ACPI patches (SSDT-TbtOnPch-Designare-X299-EX.aml)
Please perform a cold boot after installing either one of these SSDTs and when switching between them. This is necessary in order to put the Thunderbolt controller into the correct starting condition.

Hi @CaseySJ, here are my results with SSDT-TbtOnPch-Designare-X299-EX.aml (+ ACPI patches, of course):

  • TB Boot Support ENABLEDin BIOS
    • Hot Plug doesn’t work
    • USB-C works, but system freezes completely when unplugged
    • With G-RAID only during boot:
      • Occasional KP’s on boot
      • Wake/sleep works, but still need to check for KP on wake during extended (overnight) sleep.
      • I was only able to see TB info only once in System Information –> Thunderbolt
      • IOReg tree looks proper
    • OWC dock only during boot:
      • Boots, but TB3 doesn’t work
    • OWC Dock daisy-chained to G-RAID during boot:
      • Can’t boot at all (gets stuck on BIOS splash screen)
    • OWC Dock & G-RAID Plugged into different ports
      • KP during boot (see attached image)
  • TB Boot Support DISABLEDin BIOS
    • Mostly KP’s during boot with TB devices plugged in (see attachments)
    • When it does boot, TB doesn’t work

SSDT-TB3-Designare-X299-EX.aml wasn't attache3d, so I didn't get to try with that one

Hi, @CaseySJ

I got an interesting result today.

I tried not to connect USB 2.0 cable to flashed GC-TITAN RIDGE v1.0

then Ultrafine 4K can 100% successfully Display in cool Boot in some condition.

However, there are still some problems:

1. Thunderbolt 3 Recognize Problem

--Thunderbolt 3 devices information about Ultrafine 4K won't show up in System Info->Thunderbolt/USB4 until replug the thunderbolt cable.

--This situation also happened after sleep.

2. Sound and Brightness Control Problem

--A Warm boot is still necessary to ensure that sound control and brightness control are functional.

--However, sound and brightness will lose function after sleep.

3. Cable Problem

-- Apple Thunderbolt 3 (USB‑C) Cable (0.8 m) can successfully lit up Ultrafine 4K in cool boot.
-- Ultrafine 4K Original USB-C Cable (1.5 m) can successfully lit up Ultrafine 4K in cool boot.
-- Ultrafine 4K Original Thunderbolt 3 Cable (2 m) can't turn on Ultrafine 4K in cool boot.


Presumption

-- USB 2.0 port on GC-TITAN RIDGE plays an important role in functions of thunderbolt monitor.
-- If the cable supported DP-Alt mode, it can lit up Thunderbolt Monitor in cool boot without USB2.0 connected to GC-TITAN RIDGE.

Hello @johnny7874209,

I know this is an important issue for you and all other LG UltraFine owners, so I do sympathize. Unfortunately we don't have any good solutions. Some users like @gandem have seen good results with the on-board Maple Ridge Thunderbolt 4 controller on an Asus Z690 ProArt motherboard, but Maple Ridge controllers have hot plug issues because they are not natively supported in macOS.

Because we have no good advice for LG UltraFine, we added this Note to Post 1 a long time ago:

Which version of BIOS is currently installed on the Z390 Aorus Xtreme?

Newer versions don't need TPM Headers. Instead we just enable "Intel Platform Trust Technology" or PTT in BIOS and we're good to go with Win 11 and macOS.
