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


what would be my next step to update to Monterey? do I just download and install Monterey on top of Catalina?
Yes, an in-place upgrade is possible now. Always good to make a full backup before proceeding.
 
Yep, I did all these things. Still getting stop-sign instantly when trying to boot.
At the OpenCore boot picker press and release CMD-V to enable Verbose mode. Then boot macOS. Feel free to post a photo of the log (remove EXIF location info from photo before posting).

Also check if BIOS —> Boot —> CFG-Lock is disabled (it needs to be disabled).
 
You have multiple instances of some kexts and they are different versions.
These may be actual or cached.
Clear NVRAM.
Boot without cache and check /EFI and /Library/Extensions.

Progress has been made on the Clover side. I cleaned up the duplicates and now Catalina boots with Clover 5142. The only thing left now before I try to update (I think?) is to add what @zgonda said about ResizeAppleGpuBars.

I've put it into the config.plist like stated below. But then when I open it in Clover Configurator I get an error. See image. I will be running this system with an 6900 XT.

<key>ResizeAppleGpuBars</key>
<integer>-1</integer>


Do I need to put this in or can I leave it out completely?

Thanks!

Are you confusing OpenCore and Clover ?

A corrupt Clover config.plist is the same as no config.plist at all.

I'm using Clover. But from what I understood zgonda mentioned to add it under Clover?

If you want to continue using Clover (which is still a good choice from my point of view - I use OpenCore 0.7.5 or Clover 5142 indefinitely) you will have to update it in its 5142 version (with update day of UEFI drivers - OpenRuntime.efi in particular) and kexts as usual ...
It will also be necessary to modify the config.plist, using Plist Editor for example, by adding a Quirk in the "Quirks" section:
Key: ResizeAppleGpuBars, Type: Number, Value: -1

I have only seen it in the context of OpenCore.
It may apply in Clover too but as I no longer use it I am unsure.


OpenCore 0.7.4 has added support for RBAR by adding 2 quirks:
  • Booter >> Quirks >> ResizeAppleGpuBars: reduces GPU PCI BAR size to be compatible with macOS.
  • UEFI >> Quirks >> ResizeGpuBars: configure the GPU PCI BAR size for systems other than macOS.
ResizeAppleGpuBars affects only to macOS and ResizeGpuBars affects all other operating systems.
 
Ok, would you know if this key would be requirement to run Monterey with a 6900 XT?
ResizeAppleGpuBars is only necessary when “Resizeable BAR Support” is enabled in BIOS. If so, we set the OpenCore quirk to 0, otherwise we can leave it alone (default = -1).

Ok, Thanks! Does this mean I can take the plunge and upgrade from Catalina to Monterey at this point then, running Clover 5142 and latests kexts?
