After successfully installing the Catalina and Opencore bootloaders, I encountered a problem that some applications would crash after waking up,
Such as Chrome and Tencent QQ, these applications will become unresponsive and only be quited by force, even the system could not power off normally.
However, none of these problems occurred before sleep.
In addition, all of these issues occur when SMBIOS is iMac and iGPU is enabled in the BIOS, but not when SMBIOS is iMac Pro or iGPU is disabled in the BIOS.
I am thinking that the problem may be iGPU related and I cannot fix it.
please help me.
I have attached my EFI and IOReg files
Asus Z170i Pro gaming
Radeon RX580 8GB

I have upgraded from Mojave to Catalina 10.15.1. It went almost flawlessly. The only issue is the computer not waking up from sleep. Just a grey screen. Hard reset is required. Of course I have been searching the Internet but to no avail.
The sleep-awake cycle did work on Mojave.
I have noted that it is now impossible to boot in save mode. Trying to do so produces the message: " error loading kernel (0xe)" .
Since I use Clover I have tried the bootflags -f en UseCache=no (in addition to -v en -x) . I wonder if the last one is a Clover bootflag?
Here are my specs:
Motherboard Gigabyte GA H77 D3H rev 2.0
MacOS Catalina Version 10.15.1 (Build 19B88)
Kernel Darwin 19.0.0 x86_64
RAM 4.00 GB
Model Identifier iMac14,2
CPU Intel(R) Core(TM) i3-3225 CPU @ 3.30GHz
Intel Generation Ivy Bridge
Any help is of course much appreciated!
