Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

[CaseySJ]

@CaseySJ Here I send you the new screenshots, but I think it is the same result

I remember this post of yours from July 2019. Was the VRS8 working properly with Designare Z390? If so, was it running Mojave?

Your Thunderbolt controller is already working. Have you connected a Thunderbolt device?

Yes, all was working flawlessly with the z390 and mojave, later I update to catalina and still was working properly.
I believed that with the z490 and opencore was gonna working equally, but I think I should have reading more information before the upgrade

- Yup. I installed macOS already with rx580 which works and I could check my rx580
- But my rx580 has glitch and freeze(randomly) problem like this

(I tested only one monitor each time.)
- rx580 and new rx5700xt works in windows10 without problem.
- My monitor is LG 34UC80-B(https://www.lg.com/us/monitors/lg-34UC80-B-ultrawide-monitor)

I think someone has cursed me
I heard most of your EFI was successful without any problems.

Update
With rx580, all installing process works. I'll try changing gpu from rx580 to rx5700xt again!

I know it's super late for this issue, but I'll post anyway. Sometimes you can get used RX 480 / 580 with memories that are dying, the seller will lower the clockspeed by modding the VBIOS. Maybe macOS does not read the new lower value and loads the 2000MHz standard for RX 580 so that's why it does work stable only on Windows.

Yes, the Apollo x6. I have the uad software installed, but its telling me that there are no devices found.

@CaseySJ Thanks a lot for such a very thorough guide. I was able to install Catalina with i7-10700K on Vision D in almost one click with modified Thunderbolt ROM. Works like a charm, didn't figure out any issues.

Hardware I used:
Intel Core i7-10700K Desktop Processor
GIGABYTE Z490 Vision D
Samsung 970 PRO 512GB NVMe M.2 Internal SSD (MZ-V7P512BW) [Canada Version]
AC1750 Dual Band Wireless Card, BCM94360CD Desktop 5G
Corsair CP-9020178-NA RMX Series RM650x 80 Plus Gold Fully Modular ATX Power Supply
G.SKILL Ripjaws V Series DDR4 3600MHz 32GB(16GBx2) Memory Kit
Corsair 4000D Tempered Glass Mid-Tower ATX PC Case - White, CC-9011199-WW
MSI Radeon 580 8Gb
KeeYees SOP8 SOIC8 Test Clip and CH341A USB Programmer (as a SOIC8 clip only)
Raspberri Pi Zero W (via SSH )

Few pics attached

Do I remember correctly that you flashed the Z390 Designare in order to use the Slate VRS8? Were there some other settings that needed to be applied? There was some mention of "luckyal" and his findings.

Meanwhile, it is also possible to flash the firmware from Z390 Designare to the Z490 Vision D. However, it seems that Thunderbolt is NOT the issue now. The Slate VRS8 is connecting, but the Slate drivers are not recognizing the device.

Also do the following:

• With the Slate connected, run IORegistryExplorer and select File --> Save As..., then post the saved file.
• With the Slate connected, open Terminal and type kextstat | grep -v apple and post the output.

Hello @happyjohn78,

Welcome to the forum, and what an entrance!

• No issues with installation.
• Thunderbolt firmware flashed.
• And I trust you're also using a custom Thunderbolt DROM?

Flashing the Thunderbolt firmware (successfully) also inducts you into the Society of Mad Scientists.

Good job.

LOL - I like that name - Society of Mad Scientists

I didn't dig deep into the customizing Thunderbolt DROM - I used one you prepared and uploaded in your tutorial. Read it, checked it (manually) and used after that. Just need machine to be in work condition today.
