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

So Luckily, I was able to use Time machine to roll back to Mojave without loss of my Lan Kexts/functionality.
I was able to make it to Config_AMD_gpu plist from Step#1 of the Mini installation guide : Page# 1729 Mini guide for Mojave to Catalina using Z390 designare

I got a gotcha, seeing when trying this step:
If you have a supported AMD GPU (AMD RX 560, RX 570, RX 580, RX 590, Vega 56, Vega 64, Radeon VIII, RX 5700, RX 5700 XT):

• Copy the file config-AMD-GPU.plist to the CLOVER folder on the USB disk (EFI partition) and rename it to simply config.plist.

When trying to copy, then rename, there was already another config.plist already present and thus did not allow me to rename. Did this occur being that I needed to copy and rename with a plist editor ?

Not sure where you got V1.3 from (I haven't gone through the 100 pages of the linked thread) but there is an updated version, 1.4, on MacRumors, here.

• Vega 56
• Vega 64

I came across this a few days ago but it looked like its creator had removed Vega support because it brought back the fan issue, do you know if this was resolved? or do we have to load some kind of PP fan control using VGTab?

Can't you just rename or delete the old version and then copy the new one and rename it?

He also has a thread going on MacRumors, here. Now at V1.4.

I'll certainly try it. I was just skeptical in doing so, as I didn't want any catastrophic repercussions in attempting to do this. I've done this plenty of times in Windows but not while building a major system upgrade/mac osx update.

Thanks Ploddles

Just rename the current config.plist something else but ending in .plist, eg oldconfig.plist.
If the new config.plist gives you problems then you can boot with oldconfig.plist from the Clover menu to get back to where you were.

@NCMacGuy--have you tested your Apple Thunderbolt monitor connected to your Designare with flashed Titan Ridge chip? if so, does wake from system sleep work? if I hold my mouth just right, I can get the TB monitor working with my flashed AR card, but the monitor won't wake from system sleep.
thanks

When I was trying out the Apple TB Display with the Designare, and a Titan Ridge AIC on my Z390 Aorus Pro, I was primarily checking whether the display would work, and what happened on shutdowns and reboots. At that time I don't think I tried sleep. I haven't used the Apple TB Display since, since I don't need two displays and I don't have the desk space.

I just hooked the Apple display up to the TB3 port on the Designare to check what happens on putting the system to sleep. Well it only sleeps for about 2 seconds, then wakes itself up. When it wakes up both monitors are active.

If I were going to use this dual display setup I would have to dig in to resolve the no-sleep issue. (Something is not set properly because if the computer is off and I plug something in the back, it starts up!) Short of solving that issue I could either just leave the displays on with a screensaver, or shut the system down, since booting is so fast. On rebooting both displays are active.

I tried the Apple display plugged into the GC-Titan Ridge AIC in my Z390 Aorus Pro. On boot both displays were active. I could put this hack to normal sleep. On wakeup both displays were active. I did several sleep - wakeup cycles and both displays were always active.

In both hacks I'm using RX-580 graphic cards, if that makes any difference.

Vega frame buffer properties are back inside the kext. And PowerPlay tables were added by @rj510 to the SSDTs:

@rj510 : Can you answer the question about Vega support in RadeonBoost kext? The Info.plist does not seem to support Vega.
