ThinkPad-P52-Hackintosh VS Gigabyte-Z490-Vision-G-Hackintosh-OpenCore

I don't have detailed instruction, but you can have a look at this link. Worked for my P52 Catalina

Hello, I've been messing around with this laptop (specs below) for a little less than a week now and I still can't even get to the install screen. The screen will either go black after gioscreenlockstate 3 or will freeze just after gioscreenlockstate 3, depending on which framebuffer I'm using. The last line in the opencore log is something like SmcReadValue Key Size 1 SmcReadValue Key Size 2. I'm getting so frustrated because I know people with this cpu have made it work before. I've tried adding the suggested bootflags for whatevergreen troubleshooting. I've tried using the 4k xeon EFI from here https://github.com/liuyishengalan/ThinkPad-P52-Hackintosh and it also just goes black or freezes after gioscreenlockstate. I've tried using my fresh EFI I recently created from the guide and changing the quirks he has that are different 1 by 1, as well as other parts of the config, restarting after each change. I've tried all the suggestions from the troubleshooting guide of dortania in the kernel section.

I also tried DevirtualiseMmio on and off. I've been keeping an eye on this build https://github.com/liuyishengalan/ThinkPad-P52-Hackintosh and I also tried tweaking my config to match some of the settings on his UHD Xeon config. I didn't change too much and after testing and failing i changed it back because I know his build is old and I don't want to muck up my config. I don't really know a good way to go about transferring what he learned during his build to my config on 0.6.8. It's hard to tell whats different because it's old, and different because it's neccessary.

- hackintosh (this must be running, according to this : https://github.com/liuyishengalan/ThinkPad-P52-Hackintosh)

I used this guide to get the I225-V adapter working on my Z490i Aorus Ultra: https://github.com/5T33Z0/Gigabyte-Z490-Vision-G-Hackintosh-OpenCore/blob/main/I225-V_FIX.md

What guide/tool followed: Mostly followed 5T33Z0's guide (https://github.com/5T33Z0/Gigabyte-Z490-Vision-G-Hackintosh-OpenCore) and partly Schmocklord's guide (https://github.com/SchmockLord/Hackintosh-Intel-i9-10900k-Gigabyte-Z490-Vision-D). Additionally, followed OpenCore 0.8.8. Dortania's guide. Using OCAT for editing the config-file.

Basically read the Open Core Guide and built and EFI Folder from scratch and checked some of the prebuilt EFIs on Github that used the _same_ hardware. I spend a full day assambling the parts and then installing MacOS Big Sur. I had some problems running the installer at first, but most of the issues were related to BIOS settings. I followed the guide of ST33Z0 and his settings worked perfectly (https://github.com/5T33Z0/Gigabyte-Z490-Vision-G-Hackintosh-OpenCore)
