Installed Catalina Public Beta and the monitor is not working anymore. At boot everything is fine but the moment before the login screen appears, the screen goes black/switches off. Maybe its a problem of my Radeon VII. It happens when the screen switch from low-res to 5K-resolution. Sound and cam works...
I verified that the loss of function after LG 5K sleep wakeup problem is solved for Z370 motherboard.
1.For Gigabyte Aurus Gaming WiFi, the right BIOS is F5.
Bios F4 doesn't work.
2. You need to change the Thunderbolt address in the SSDT, following the method at the end of the author's post. Mine is pci0 rp5.
3 It solves the problem of LG 5K, which lost all the functions: camera, sound,.. without this remedy.
Now, thanks to this guide, LG 5K works perfectly in Hackintosh.
Overview
The Thunderbolt hotplug is a problem that has existed for many years, and until now the only way to have working TB devices is to connect them and turn them on before boot.
Finally after a long time some progress has been made.
This is not a guide! But a starting point for further progress.
CHIPSET X299 - TB on PEG
Thunderbolt hotplug is fully supported!
The complete guide for the X299 TB hotplug can be found HERE in the @kgp guide.
OTHERS CHIPSET - TB on PCH
The hotplug has not yet been fully implemented for now, but considerable progress has been made. ATTENTION:
All the next SSDTs are based on my ACPI paths (PCI0.RP05), if your paths are different you have to modify them inside the SSDT.
> If you're not familiar with this check the EXTRA part at the end of this post <
For many Gigabyte user with 300_Series chipsets, the hotplug now works perfectly!
Seems that the TB hotplug is BIOS-dependent.
What you need:
It is necessary to update/downgrade the BIOS to a specific version that shows this description:
Update CPU microcode for upcoming CPU
Improve windows boot time
For example for the GB Z370 Ultra Gaming is the F10. View attachment 382026
Remember to clean the CMOS after bios update and use the appropriate settings for your OS.
At this point in the section Peripherals/Thunderbolt, use these settings: IMPORTANT!! Do not change the settings inside the red square!! They could kill your PCI-TB card. View attachment 382028
Save everything and boot your system. I suggest doing an NVRAM reset by pressing f11 on the clover screen.
Now download the SSDT TB from the kgp guide, or use the one pre-edited on this thread: DOWNLOAD SSDT-Z370-THB3HP
No other clover settings are needed. Reboot, et voilà!
Unfortunately I do not know if the new Titan Ridge works, because it requires a later BIOS version.
If you use a TB dock (with auto power off), turn off the ERP in the bios, otherwise it will not turn on automatically at boot, but you will be forced to disconnect and reconnect it.
There are other ways to have the hotplug, but they are incomplete..
METHOD 1 Experimental SSDT to force the hotplug on TB port 1 Works only with the THB_C cable connected.
If you have only one Thunderbolt device you can use next two SSDT!
Both SSDTs add the PCI information to System info.
USB-C not tested, I do not know if it works correctly.
Both ssdt work up to the second device, the next ones are not disconnected/reconnected correctly. These SSDTs (V1 and V2) could be cause reboot after shutdown, it is recommended to use Fix Shutdown in Clover.
A) SSDT V1: Download
No arbitrary inject in Clover are needed.
I inserted the "PCI-Thunderbolt One" _DSM Method on DSB1 and in this way you can hotplug one device at a time.
Precisely this is what happens:
STEP 1: UAD-2 Satellite and Apollo Twin connected and turned on at boot time.
STEP 2: I turned off and then turned on the only the Apollo Twin, which was reconnected properly.
STEP 3: I turned off and on both devices, but only the first (UAD-2 Satellite) connected correctly.
B)SSDT V2: Download
No arbitrary inject in Clover are needed.
This is similar to the SSDT V1, but I added the "PCIHotplugcapable Zero" _DSM Method on DSB2 (like in iMac18,3 and iMacPro).
STEP 1: UAD-2 Satellite and Apollo Twin connected and turned on at boot time.
STEP 2: I turned off and on both devices, but only the first (UAD-2 Satellite) connected correctly, while the Apollo Twin is not recognized correctly.
The addresses of the devices change, in fact they are mixed in a strange way on IOReg.
METHOD 2 (without THB_C cable): SSDT below PREMISE: This method is only applicable to those using a PCI-Thunderbolt card and it can be useful to those who use a TB dock because it requires a device connected and turned on at boot.
Based on a discovery made by @crismac2013, I removed the THB_C cable from my GC-Alpine Ridge and something strange happened.
If you turn on the computer without Thunderbolt devices connected the PCI-TB card is not loaded, see Ioreg:
But if I have a device connected and turned on before boot the PCI card is recognized and loaded correctly, but not only, in this way you have the hotplug of all devices!
Because this happens you have 2 choices: 1- Add these Arbitrary inject on Clover:
The PciAddr is that of PXSX (See on your ioreg):
2- Or use this SSDT without Arbitrary inject: SSDT V3 Download This solution is preferable because in this way the connected devices are shown correctly on System Info under PCI.
To succeed try these steps:
1- With your computer turned off, remove the THB_C cable.
2- Boot, enable Fix Shutdown* in Clover and add the SSDT
3- Turn off the computer
4- Connect the TB dock (The TB docks are equipped with auto power off, check that once connected it will turn on -green LED-)
5- Wait few seconds and turn on the computer
Now you should have the hotplug of all TB devices.
*I noticed that with Fix Shutdown the computer is not totally switched off, the USB and TB devices remain on.
The main problem is that when the TB is shared in the PCH lines it is not loaded by the system without THB_C cable, unlike those who have the TB under the PEG lines.
Obviously this is not a solution, but it makes clear that the problems with the TB hotplug derive from the functions that add the THB_C cable, so we are faced with two ways:
1- Finding the way to make the PCI card load from the system even without a connected THB_C cable
2- Understand what features this cable provides and whether it can be found in ACPI paths to include it in the SSDT. This would solve the problem for everyone.
>> Anyone who discovers something new that can help, is invited to share it possibly by inserting IOREG or any other data that can help to better understand <<

EXTRA:
An idiot mini guide to change the SSDTs ACPI path correctly
Download IORegistryExplorer.app (search on the web)
Download the last MaciASL.app from Rehabman repository: Download
Open your IOReg and type "Thunderbolt" in search bar in IOService view. View attachment 327939
If your ACPI paths are different from mine (PCI0 and RP05) you will need to replace them.
Then open your SSDT with MaciASL and go to Edit > Find > Find and Replace
Check that they are correct and click on All (I entered RP09 as an example).
Do the same thing also with PCI0 if it is different from mine. View attachment 327941
When you have replaced all ACPI paths, save and exit.
There is a conflict among XPG 8200 Pro NVMe M.2 SSD and the Gigabyte Z370 Gaming WiFi and Gigabyte Thunderbolt aic.
The second M.2 socket can't coexist with Thunderbolt functions. The Thunderbolt configuration option will disappear in the BIOS setting. To solve this conflict, you can use the the upper M.2 socket near the CPU.
New LG Ultrafine 5k has Titan Ridge inside (instead of the Alpine), so you now only need one DP-in to make it work at 5k (example the Gigabyte Designare with TB3 support built-in)

Yes, that's why I say that if you use the Gigabyte designare with TB3 support you only need one DP-in to make it work (that of course goes through TB3)

I assume what you mean is that you will feed 2 DP from your video card into the Titan Ridge card which will allow you to drive the monitor off of a single Thunderbolt 3 cable? I THINK that should work...
