Hi All

I'm trying to make things real fot ASUS AIO PRO 240IC
I'm able to install using Intel inject but get no more 31 Mb VRAM at all

Would you please guys be so kind to help to get it real.

I can't find _INI for _SB.PCI0.PEG0.PEGP
Just _ON and _OFF

So what should I do to disable dGPU
Is it should be just as easy as add

Method(_INI) { _OFF() }

to SSDT-8-OptTabl.dsl ?

Is it worth in terms of getting more VRAM at the end?
Now I'm stuck on IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, in case Intel injecting using pseudo id is off

I'm following with this great manual ( thnx a lot, sir ) https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

Thnx

Thanks @RehabMan for the great guide and support.
I wanted to point to a nice and simple method in the OpenCore guide, that seems to be the way to go now:


By adding the property as described there, I successfully blocked my Nvidia GPU which made sleep work on my laptop.

Hi.
@vgerris, is this guide for AMD based mbp 2011 17'' as well? I see the OpenCore has many limitations but I am not sure. What is your machine you used this on?
Does anybody knows what does this mean? This is in the guide. How do I disable it?
CSM must be off in the BIOS for the spoofing to work correctly, especially on AMD CPU based systems.
