Hi, 

I don't have a surface book 2. I have the surface book 3 i7 version with Nvidia chip and so the EFI's will be different. These EFIs are built for surface book 3 such as the ice lake professor and so you'd have to edit a few things in them to get a good match. 

Your best bet would be to use one of the EFIs from Olarilla. Find the EFI built for your processor. Edit the EFI, remove the Boot Args it  has and use <string>-igfxvesa -igfxblr -igfxcdc -igfxdvmt</string>"

And then once installed and you've booted MacOS change the boot arg from -igfxvesa to -wegnoegpu. 

But as for the graphics... I believe you are saying that only the intel graphics chip is working which is correct for Mac's. You will never get the Nvidia chip working as Nvidia have stopped supporting them a few years back. 

Sorry 

Hello!

There is not that much diference between EFI folder in surface devices from what i have seen. The real problem begin when you start to add "little thing" or try to make things work.

I fixed the problem with the applekeystore thing by just removing the boot args of the verbose mode. 

 

The problem that i have now is that CPU is always running at +40%. Using "top" in the terminal shows that kernnel task is running at 200%. I have tried many things, opened a new threat. Uploaded everything there.

Hi,

So I've just glanced at your EFI. 
Did you use? Gathering files | OpenCore Install Guide (dortania.github.io)  ?? Check out this guide if not and follow it as best you can.

I think you have the wrong SSDT's for your processor. Your processor being Coffee Lake, I think. I noticed one missing SSDT which is the SSDT-Awac. Add this to the ACPI folder and config file. But if still running at 40percent then remove SSDT's and download correct ones from that website for your processor.

Also you're not running the BigSurface kext??? 
GitHub - Xiashangning/BigSurface: A proposition for a fully intergrated kext for all Surface Pro hardwares

This is a must. Follow the guide as there a few tweaks to get yours working correctly.

I managed to install successfully Ventura onto my SB3. But the VRAM has only 26 MB. Can anyone help me?

Hello, nice to meet you. I will listen. We also hackintoshed the Surface Book. 　 Although the built-in speaker cannot be used, there are compatible Kext etc. Thank you.

Hi guys

Can test? EFI Test.zip

-Delete old EFI folder and paste new. Don't use merge files
-Don't use Drag and Drop into EFI partition. Use Copy/Paste instead
-Reset NVRAM one time - with OpenCore use entry "Reset Nvram" / with Clover use F11 key on boot screen
