10.12.4 Bad Graphics Glitches (Intel HD 4600 | NVIDIA GeForce 940 M)

[Zemus77]

Hello,

I have an MSI GP60-2QE gaming laptop that I was able to install macOS Sierra 10.12.2 on. I am currently multi-booting Windows 10, macOS Sierra 10.12.4, and Ubuntu LTS 16.04 from the same hard drive.

I had most things somewhat working (audio would sometimes work, Intel HD 4600 was recognized but only using 7mb, etc..) and was in the process of trying to tweak everything/find what kexts would turn this into something more usable.

I decided to update to 10.12.4 and was unable to boot at first, but upgraded to Clover UEFI r4049 and have managed to be able to boot into macOS again. Unfortunately, I now have a really bad graphics glitch that causes everything to be very distorted, repeated, and just messed up overall. I can barely make out anything on the screen.

At first I thought my actual hardware was failing, but everything is fine on Windows and Ubuntu. I've added screenshots to help explain what's going on.

Has anyone had a similar experience or have any advice of what I could look into to resolve this issue? Also, please let me know if there is anything else I can provide that would help in finding a solution. Any help would be greatly appreciated.

Thanks

Enable legacy boot/CSM in BIOS.

Wow that was an easy fix, thank you so much. I thought it was a much more complex issue. What exactly did that do? I'm assuming that you posted this somewhere else on the forum and I just missed it somehow.

Legacy/CSM causes BIOS to initialize the graphics hardware differently...
and it seems to be more compatible with what macOS/OS X expects.

It is in the guide...

BIOS settings
...
Note: If you get a "garbled" screen when booting the installer in UEFI mode, enable legacy boot and/or CSM in BIOS (but still boot UEFI). Enabling legacy boot/CSM generally tends to clear that problem.

After update to 10.12.4, my intel hd had showed to 1536 Mb but the accelleration still off. I already change the bios startup both into legacy > UEFI first and legacy > legacy. Did I miss something?
