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

Now the question is wether to risk BIOS update or just leave mitigations in place. Even though it's not on the list I believe the z690 Pro Art is also impacted as I found the UEFI exe in my System32 folder when I checked (don't have the name handy right now from one of the articles).

No worries. Configuring OpenCore EFI is quite easy as follows:
.

Im working on switching from Clover to OpenCore so i can update the OS and I used the above steps to create a USB drive but I cant boot into MacOS. I get the Apple logo and progress bar on a black screen and then a fully black screen. Using BIOS F9i and CFG-Lock is disabled.

cmd + v when you boot so it starts in verbose mode.

Then come back here & post where it stops in the boot sequence.

I've followed all of the steps in the guide, and, when I try to load OpenCore, the sequence goes like this: BIOS -> Select OC USB Drive -> OC Disk Chooser -> Reset NVRAM -> BIOS -> Select OC USB Drive again -> OC Disk Chooser -> Select main startup/Catalina drive -> Apple logo, progress bar, black screen.

I've tried using verbose mode, and I get a stream of messages before the screen goes black. But I cant read the output before it goes away. Running an i9 9900k and Z390 Designare build based on this original thread. Could it be an NVRAM issue that isnt being fixed by OC NVRAMreset?

1. Make sure you are not using some XMP (extreme memory profile) that is causing some instability in the bios

2. Keep a phone handy with the camera pointed at the screen & record a video (for yourself) when the verbose boot sequence starts.
That will make it easier for you to go through it to last frame & save that to get an idea of where in the boot sequence it reached before fade to black

I used the 2nd item to diagnose when I was having issues and my xmp overclock was making the system unstable.

Also.

What version bios & opencore are you running ?

Having a hard time getting verbose mode to come up. CMD-V after selecting the start up drive in the OC chooser right? It seems to ignore the input.
No XMP is active. BIOS is F9i and CFG Lock is off. OpenCore is version 0.8.3
Other than that my BIOS setting are as they were when I did my original Clover install. Are there additional BIOS changes that are needed for OpenCore?

This may require Misc>Boot>PollAppleHotKeys: true.
Or just add '-v' to boot-args (under NVRAM).

Please let us know if the WiFi/Ethernet problem gets fixed with matched memory. This is the first such problem report.

Hi @CaseySJ and @madmax559, after matched Memory without success with wifi (Fenvi), I reset BIOS because I can´t boot, accidentally bootup with WiFi and Bluetooth enabled, then I look profoundly which configuration works, and I found when enable iGFX wifi goes out.

If you enable iGFX, then you may be using the USB-c/TB out in which case the BIOS will not show at the screen

This also assumes that you have a video card in there where you have DP Out from video card -> DP IN on motherboard

To see the BIOS at all times even with iGFX, use the DP out from video card or HDMI out from motherboard to the monitor, just to be able to debug stuff
