The display turns off for 60 to 100 sec. then the OS shows up normally on seqouia and sonoma

Mac OS Sonoma runs normally but after apple logo the display turns off for 60 to 100 sec. then the OS shows up normally

• Sometimes it stays black and never boots
• some times it loads normally without any issues very fast after the apple logo without display off

Any idea who to fix this

Questions:

1. Do you have the AMD IGPU enabled in your bios?
2. Are you using the RX570 for all graphics processing in Windows and macOS?
3. Which graphics kext are you using in macOS, WhateverGreen or NootedRed?
4. Which cable(s) are you using to connect your Hack to the Display(s)?
5. Are you using any adapters or adapter cables to connect the display(s)?

Thanks for your help

1- yes igpu Disabled in bios (but I tried it after booting it worked as a second screen however I disabled it from bios)
2- I am not using Windows - Hakentosh only but yes I am using it as the main Gpu
3- I am using booth kexts (whatever green and nootedred)
4- I am using Display port I tried HDMI the same result
5- I am using DP Direct without adapters

There's your answer. They conflict with each other. As you've got the iGPU disabled you don't need NootedRed so remove the kext and remove the entry from your config leaving only Whatevergreen and it should work.

I disabled the kext nootedred and its entry but the same problem and 1 more problem appeared the display turn off after 1 minute the pc running but no display

Latest kexts? The RX570 shouldn't need any boot args so remove agdpmod= if you've got it.

Hello Shaneee

• The problem of the display turning off after the system runs was from the PSU. I have changed it to Fresh new 650-watt GAYGABYTE
• When i removed nooted.red, there is progress, no boot failures for now
• When I removed apgmod=pikera Display port wasn't working I framebuffered the GPU using orico it worked
• Now the Hardware encoding is working wasn't working before. Booting is much better, but I still have a black screen with backlight on after verbose and after this black screen, the Apple logo appears again and loads the desktop normally

I've attached my config files

Post a copy of the WHOLE EFI folder, so we can see exactly what you are using.

The config.plist doesn't tell us the whole story when it comes to an OC setup.

Here is the EFI File
I have to mention that after framebuffering, Isleep is not working

I will have a look at the EFI tomorrow.

Hello Guys,
Thanks to your help, I discovered that the PC was configured to manage the iGPU only
As I installed the RX570 after a few months from installing the hackentosh , the GPU wasn't detected correctly

I have installed a fresh installation with fresh EFI creation, it's now working fine
