yes analyzing ioreg I have not observed carefully , but the problem is what you wrote. it is very probable that 2 identical PCs have different HW components and/or different ACPI so it is easy to deal with problems similar to yours. All is well, that ends well

Certainly there are aesthetically identical PCs, the problem is what is inside the body. Example you could have 2 identical PCs also as HW but the components could change. In my opinion you have 2 different Trackpads, you may need additional kexts https://github.com/blankmac/AlpsHID

ECEnable.kext it should activate the battery functions. I used the kext and deleted the ACPI patch. I repeat SSDT-Rehabman was destined for Clover until 2017\2018 then Opencore arrived but Rehabman withdrew and no longer updated his works. If you don't want to do big work in your EFI you can use Opencore Mod_NO ACPI .... This version is like Clover not forcing ACPI file upload on other OS. Try this EFI Ioreg if it ALWAYS boots. https://drive.google.com/drive/folders/17bYQYdxXE3NxSySodRrR_cqFj6EDW0HD?usp=share_link List of changes from the base EFI: Removed Battery EC parts , removed rename in config . Removed SBUS SSDT, do not use with VoodooRMI. The USBPort kext was based on SMBios 13.1 I adapted it to Ventura by editing the plist. SSDT should boot windows from opencore now. When I read ioreg I will try to improve further

https://drive.google.com/drive/folders/17bYQYdxXE3NxSySodRrR_cqFj6EDW0HD?usp=share_link Ioreg if start , I found a DSDT on the net and created suitable patches, if this EFI doesn't work I need a DSDT origin to be able to work on a specific DSDT. If so, update the Bios and pass a DSDT coming from your Bios

Post EFI and ioreg , SSDT is old made by Rehabman for Clover , efi needs to be fixed , SSDT and rename need to be adapted to Open core

https://ibb.co/CKrKrGP I went back to this problem , fixed it and now the graphics work . Just for acknowledgment, you can bypass the Bios problem with IGPU patches. I'm editing the post tonight and attaching everything, I'm interested in your opinion. EDIT: I found the patch on the net by a miracle

Test this EFI if start ioreg , If something doesn't work, we'll fix it later. If you install the YogaSMC panel you get added functionality for the FN keys and fan control. https://github.com/zhen-zen/YogaSMC/releases/tag/1.5.3 YogaSMC-App-Release.dmg Install this app

Post all EFI please

You need ioreg to help you

Test this File , update OC V 0.9.0 and Kext with OCAT . Ioreg if start. https://drive.google.com/drive/folders/1QziXZmvJOJetk2-lEQJCPN8VwIKjRLB-?usp=share_link

EFI OC 0.9.0 use OCAT to manage the Config.plist. https://drive.google.com/drive/folders/1Nliw3lj72TqhUx9I_Xe87aouJQJCxE5A?usp=share_link Try this EFI, Corrections: Fix SSDT PNLF Add Kext SDReader Fixed Kext USBPort not loading as it is done with SMBios Macbookpro 11.4 Removed Useless Kexts ECEnable is not needed on DELLs, it should still see the battery PciRoot(0x0)/Pci(0x3,0x0) is wrong contains strings for IGPU. Test in USB if start ioreg. I advise you to compare each section of the config because I changed various things.

I see you already have the SBUS device in Config.plist, this conflicts with SSDT-SBUS. In this case it is more correct to have SSDT-SBUS. Remove the SBUS patch device and leave SSDT. Let me know if that solves it.

When you test I need ioreg, I still have to fix the USB type C. What you are saying seems to me to be a NVRAM issue. Try clicking spacebar at Opencore GUI, then select resetnvram and test. Among other things also check that you have the latest Bios available if not update the Bios.

"Thunderbolt Boot Support" Disable. Open ioreg search for RP05 (here you find your TB3) See that in these 2 Ioregs you have the patch active. So SSDT-TB3 works, I just need to modify it. I leave the modified EFI to test. https://ibb.co/PYsrFJc EFI for Monterey. https://drive.google.com/drive/folders/1QjGKs9MDcRksvwlk-9QF-wu74D-C7-Df?usp=share_link Try this, ioreg if start, you need to save ioreg after connect type-c hub and TB3 dock. Thank you.

https://drive.google.com/drive/folders/1Ium8_7ikah-nNxOCJqsvBVe5lXyghibd Test this fot TB3 this USBport.Kext have Hs 03-06-08 ioreg if start

In this ioreg TB3 still does NOT work, in bios you have to set the correct options for TB3.

If you want to try this EFI I fixed some things, from ioreg I see there is to fix the TB3 if this EFI starts ioreg and then I fix the TB3. EFI OS ventura https://drive.google.com/drive/folders/1QjGKs9MDcRksvwlk-9QF-wu74D-C7-Df?usp=sharing Here in this repository is the example for patch TB3 , it works hotplug and sleep\wake. Obviously SSDT-TB3 must be adapted to the TB3 in use. https://github.com/Baio1977/Lenovo-ThinkPad-X1-Tablet-Gen3-Kabylake-r

Thanks for the replies and I have a few questions: Patch stolenmem solves the DVMT problem in theory, this determines whether the PC boots or not. So I think the problem is elsewhere as logic. Much more likely a connector issue, I think. I would like to extrapolate as much information as possible and try to understand the problem and actually determine NOT compatibility with Hackintosh. For a complete debug I add kext debug in the traditional efi and related botargs??? Here I extrapolate info on video connectors???? Thanks for the valuable info.

I bought this fantastic Tablet, I've been going crazy for a few days to have the video working on the integrated display (3000x2000). I leave everything in my possession attached and I hope someone can decipher the logs and understand the problem. I can only view the video on external screen via TB3 Dock. https://drive.google.com/drive/folders/1JjNKLTJrNsqpnTw9fECbo_dMTV4x1JUH?usp=share_link

USBs are not good, remove the kext for port mapping and redo it maybe from Hackintosh. XHC is seen as a HUB. https://ibb.co/ynZY4SR

Ioreg made by the 2 efi could reveal the mystery, it would show us the differences between the 2 EFIs.

Attach ioreg and let's see if the configuration is OK, other kexts may be needed to activate everything. BT, SD reader etc etc ......
