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

[iRamon]

Thank you for running these tests. Some questions (for the sake of scientific rigor ):

I love your scientific rigor, it has led to many solutions and insights .
Not so sure if I was as meticulous as you would have been, but let me try:

• During each test, did you (blindly) press Enter at the (invisible) Clover Boot Menu to boot macOS?
  No, I had my HDMI monitor connected to the GPU card during all tests. The Gigabyte bootlogo, Clover Boot Menu, Apple loading screen, and macOS were all displayed on my HDMI monitor.
• If so, did the Thunderbolt Display turn on at any time during or after the boot process?
  No, the Apple Thunderbolt Display did not turn on or show any sign of life during my tests.
• During each test, did you connect a second monitor simultaneously so that Clover Boot Menu appeared on that monitor?
  Yes, the HDMI monitor was connected at all times during my tests.
• If so, did the Thunderbolt Display turn on at any time during or after macOS was booted? Or only the second monitor was active?
  Only the second monitor was active. The Apple display behaved as if no power cord was connected.

My hackintosh is normally configured with iGPU in headless mode, driving a BenQ 4K monitor attached via DP to my GPU card, and the HDMI monitor as a second screen, also to the GPU card. For the tests I've disconnected the 4K monitor and routed that DP-port to thunderbolt via DP-in on the Designare. The HDMI monitor was connected in all tests.

I did Test 1 (headless mode) without rebooting, just hot-plugging the Apple Thunderbolt Display to each TB3 port.

Then switched my config.plist with the iGPU-enabled configuration and rebooted. Then did test 2 (GPU DP to TB3 + iGPU active) hot-plugging TB3 ports. Finally, disconnected the DP-cable and did test 3 (iGPU to TB3) hot-plugging and without rebooting.

Your questions made me realise that rebooting vs hot-plugging could make a difference, so I just completed the same tests again, this time rebooting after each change instead of hot-plugging. The outcome did not change. The Apple Thunderbolt display does not turn on at any time, and none of the other USB-devices (webcam, sound, network, USB ports, Firewire port) become active nor visible in System Report / IOreg / Settings.

At some point I plugged in a USB-stick and USB-mouse to the back of the Apple Display. The mouse's laser would not even light up. Final test I did was to connect the display to my MacBook to validate the display still works, and it does.

Guess it's safe to say and confirm now that the Apple Thunderbolt Display does not work with unpatched Thunderbolt firmware on the Designare.

You can imagine my excitement to try patching the thunderbolt firmware and see the display come to life!

Thanks for the quick reply.

Attached is my new issue when selecting Boot MacOS Install Prebooter from Preboot. I've been searching around and have tried both making sure I ran kext utility after updating those kexts to their latest versions, as well as a soft CMOS reset with no luck. For each attempt I started from the Update Now button rather just just selecting Boot MacOS Install Prebooter from Preboot.

After the CMOS reset, did you make sure your bios is configured correctly? And are you sure the MSR 0xE2 register is unlocked? See for more details: https://www.tonymacx86.com/threads/...olt-3-i7-9700k-amd-rx-580.267551/post-2092711

Hello Casey per my last post. The display screen of my BIOS I posted ... the tweek screen was the only place I made setting changes ... set C state off ... and the other I set ... still stable and no issues

i5-9600k instead of i7-9700k -> can I use all the DSDT's from this golden build ?
- men would use 2x 16gb instead of 4x8gb
thanks

don't use thunderbolt SSDT thunderbolt device can't hotplug?

Hi,
I am using OpenCore and the onboard Bluetooth is kinda working.
I see it but it does not connect to any devices.
Anyone experience this also?

Do you have the BenQ 28" 4K/60Hz monitor? What's your level of satisfaction with it?
Thanks!

For each attempt I started from the Update Now button rather just just selecting Boot MacOS Install Prebooter from Preboot.

Let's try this:

• Shutdown and flip power switch on back of PSU for 10 seconds (or pull plug from the wall).
• Turn power back on and enter BIOS Setup. Confirm that the Boot Order is correct (Samsung first, Sunbow second).
• Save and exit from BIOS setup.
• Just to be safe, press F12 at BIOS splash screen and select the Samsung SSD from the BIOS Boot Menu (not Clover Boot Menu).
• Then at the Clover Boot Menu, select Boot macOS from Samsung.
• Confirm that Catalina 10.15.4 boots up correctly.
• Now start the supplemental update once again from System Information --> Software Update.
• Each time the system reboots press F12 to open the BIOS boot menu and select the Samsung SSD.
• At the Clover Boot Menu, if a boot entry exists that contains the word Install, always choose that.

Thank you! This is exactly the confirmation we were looking for. I've added Apple Thunderbolt Display to the very top of the section Thunderbolt Devices Made Compatible After Enabling Thunderbolt Bus. (This link is also present in Post #1 near the bottom of Spoiler #1.)

You can imagine my excitement to try patching the thunderbolt firmware and see the display come to life!

Eagerly waiting to see how it goes. I trust you'll post a set of relevant photos/screenshots!
