[FIX] Corrupt color depth in High Sierra/Mojave

[AnArgentineanGuy]

Funny enough, Mojave still seems to think that my GPU is Kaby Lake.

It's exactly the same for me, Mojave still informs HD620 as the graphics, even thought I'm "spoofing" it as Skylake's HD520.

Apparently this issue affects real Macs too? I saw someone posting about the very same issue on his MacBook Pro 2018...

Same for me too, but HD620 functions will not work anymore, like hevc hardware encoding.

Hi Dex! Thanks for the guide. I've been trying to get your solution to work on my Lenovo G510's HD4600. Can you spot anything I'm doing wrong? Wrote up what I tried here: https://www.tonymacx86.com/threads/lenovo-g510-mojave-need-help-with-two-final-issues.283047/

Thanks!

EDIT: Nevermind. Fixed it — issue was unrelated to this guide.

Could someone parse this for me? This is my EDID. Putting it in does nothing. I have color banding and it's driving me bananas! I assume that something in here needs to be changed.
