Need help disabling nVidia on Haswell/Intel 4600HD

[RehabMan]

If I may add my part to this conversation.

I have been having the same problems as Dragster27, I'm using a Dell Inspiron 7537 Intel HD4400 (with Optimus GPU disabled through SSDT). My display is also "garbled" when I try to boot macOS 10.13 + with Intel injected. Strangely enough, this does not occur when I close the lid and connect through an external monitor using HDMI. Here is where it gets weird.

I'm using a 34inch (2560 x 1080) external monitor, and on Sierra that was the default resolution when booted with the external monitor. However, on 10.13 + the external display uses my native screen's resolution: 1920 x 1080 (16:9). And I cannot change the format to match the 21:9 profile.

I have experienced this earlier in the beta builds of macOS 10.13. I'm using the FakePCIID kexts with patched DSDT and SSDT. So, Dragster27 I'm with you on this one.

Hi there RehabMan!

yes, it works! I tried it this morning and I was able to install High Sierra GM! I just had to disable IntelGFX injection in Clover to get the installer to look OK, otherwise I was getting a garbled screen. Awesome, thank you very, very much. You're the man!

BTW, I just have a problem though. When the installed MacOS High Sierra boots I get a garbled screen in the laptop, external HDMI display works fine so I have to either lower the resolution or close the computer lid and open it again for the screen in the laptop to show fine... any ideas?

Attached is my final (working) configuration.

Thank you!

How did u made it work can you provide a brief instruction.

Apologies. I've attached my Clover configuration to this message. I forgot to mention yesterday,
that when I close the lid my screen turns about 90% normal. But it still flickers, and I have these
so called "dots" on some bitmap images.
