Gigabyte Z390 M Gaming build with working NVRAM

[pastrychef]

I've got a weird new (for me) problem. I got a new Benq SW270C monitor and installed it's calibration software. This monitor has hardware calibration so after calibration it writes the LUT file to the monitor's hardware. During the writing of this LUT file the computer crashed and restarted. I proceeded to recalibrate and this time the LUT wrote successfully including running the verification process. All seemed good.

But now every time I boot I get the "you shut down your computer because of a problem" message. I get this message regardless of whether I click cancel which does not load applications running a time of crash or open which does. It also doesn't matter whether I restart or shutdown and then boot. As far as I can tell there is no issue with booting and after dismissing the message everything seems to work fine. It is quite annoying.

I can't think of what to try other than resetting NVRAM which I have done. Googling did find a few instances of people complaining of similar experiences using a real Mac but no remedy was proposed.

Any ideas? Does anyone know how the Mac knows it didn't shutdown properly? Maybe some file or something is lingering after that initial crash so it still thinks there is a recent crash. Or maybe during restart/shutdown something actually is failing but I have now idea what.

Any help is appreciated. I don't know where else to turn.

Hmm... If you had a kernel panic, it should be saved to NVRAM and clearing NVRAM should get rid of it.

Try launching Terminal and entering:

nvram -p

Do you see your kernel panic?

I don't see any kernel panic in nvram. It all looks normal to me. Just in case here it is:

Yeah. No panic there... I don't know what else can cause that message to pop up.

Thanks anyway. I found one place that said the applying next MacOS update made the message go away. That’s not to say the update actually fixed anything. It just refreshed something. Fingers crossed that will work for me.

<< Solved >> - Monterey: "You Shut Down Your Computer Because of a Problem"

Hi all, I had a little bit of an issue upgrading to Monterey from Big Sur. Hardware: Asus Prime Z490-A, i5 10600K, Radeon RX 560 4GB, SSD NVME Samsung 970 EVO 1TB, OpenCore 0.78, SMBIOS iMac20,1. I had a couple of issues I was able to fix: 1 - Firstly I had to set Secure Boot Motel to Default...

Hello!
I have GA-Z390 M-Gaming with intel i5-9600k and external native Wi-Fi+BT. Graphics is Intel UHD630.
I've tried so many times to install correct bootloader, but no success with internal graphics.

About last install.
I have installed OS X Catalina 10.5.7. MultiBeast install Clover and "Core Graphics Fixup AKA WhateverGreen".

After this I've opened Hackingtool 3.8.7 - patch - System Configs - Gigabyte - Z390M Gaming [CFL].
Patch - Spoof Video Device ID: 0xe398: Intel UHD Graphics 630. (it's my device ID from intel site)
Options enabled in this menu: DP->HDMI, Use Intel HDMI, HDMI Infinite Loop Fix, Enable HDMI 20 (4k), GfxYTile Fix.
LSPCON only an "Auto Detect"

Generate Patch, export -> bootloader config.plist.
Last config booting ok, but with black screen. "No input" on display.
What should I do? Please help.

Current EFI and screenshot from connectors settings by default is attached.

P.S. is it good idea to install Catalina or should I install Big Sur? With which bootloader? I need stable system with most of Apple features as I have iPad, iPhone, Apple Watch and old MacBook Air.

Make sure you update to a BIOS version that allows you to disable CFG Lock and disable it as per post #1.

Add your own Serial, Board Serial, and UUID to the config.plist in the EFI below.

It doesn't work System error.
BIOS is latest from Gigabyte site, version F9. It is with CFG Lock and today I have disabled it - no changes. My EFI boots also with black screen (no input), your EFI throws an error. Serial, Board Serial, and UUID i've got from my last EFI - is it ok?
I've double checked BIOS settings like in 1st post - nothing helped.

UPD: That EFI worked! Thanks to pastychef!

Enable VT-x and VT-d. Disable serial port.

In config.plist, disable your video card or physically pull it.

Connect monitor to motherboard video out. Set initial display to IGPU.
