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

[CaseySJ]

Thank you very much for this guide, i will try to do everything you recommended, but i can already tell you that i had already tried to control the color profile , and a profile called XB272 is used which is also the model of the monitor.

- I managed to improve the situation in a more or less satisfactory way by setting the manual calibration on mac os to 6.700.

However i noticed that the colors are incorrect only with my hackintosh, if i connect the macbook pro(OS 10.14.6) to the monitor the colors they are normal , so i think there is a problem with the color profile of mac os catalina ...
In any case i will try to better understand the problem ..... on this computer i went from mojave to catalina, and the colors were perfect on mojave ....before installing mac os catalina i updated the BIOS to F9b i don't know if this have changed something, even if i don't think ...

-I will also check this, thank you very much for your help!

UPDATES:
- I have upgraded the Macbook to 10.15.6(Catalina) and the colors are perfect, so i can affirm that there is something wrong with the my hachintosh.

-The exact model of my video card is (NITRO + RX 580 8G G5 SE)does anyone know if this GPU has any incompatibilities with Catalina?

Please post a screenshot of the desktop background (with Catalina island) so we can see what the problem looks like. We can capture a screenshot of a rubber-banded region by pressing CMD-SHIFT-4.

Hey you all, I am thinking is it possible to change make a modified firmware for the ASRock Thunderbolt 3 AIC?
Is there something I can do to get the firmware? Also is it only possible to flash with a connection on the chip? I find this to be a bit scary, but I will try I ordered a clip and have some pi3's lying around.
Otherwise I try first the Gigabyte AIC that I have somewhere here (it works also in the ASRock boards)
I am so happy to find this I gave up on it a while ago...

Some questions and recommendations:

• Are you installing Mojave or Catalina?
• BIOS F9gis recommended now because it includes an explicit CFG-Lock option that also happens to be defaulted to Unlocked. This allows us to enable native NVRAM quite easily.
  • If installing Mojave, the instructions for enabling native NVRAM are located here.
  • If installing Catalina, the Catalina 10.15.4+ Mini-Guide includes instructions for native NVRAM.
• Regarding gIOScreenLockState:
  • Which version of Lilu and WhateverGreen are you using?
  • Are you using HDMI or DisplayPort?
  • Have you tried enabling CSM Support in BIOS?

I am installing Mojave. And I am updating to BIOS F9.
I am using HDMI on the RX580.
Lilu and Whatevergreen kexts were installed in the version of UniBeast I used.
I have CSM support enable.
I am going to try again now that I have updated.

I am stuck at this output now:

After 3 repeats of the above KEXDD stall it is now

IOconsoleusers gioscreenlockstate 3, hs 0, now 0, sm0x0

Here is my config.plist file from the UniBeast thumbdrive.

I have the ASRock Thunderbolt 3 AIC so I can try to extract and modify its firmware. It's only possible to flash the modified firmware with an external SPI Flash ROM reader/writer such as Raspberry Pi running flashrom. The procedure might seem scary (and it should!), but it's quite straightforward on an add-in-card, especially so if the simple resistor/capacitor circuit is used.
