THANK YOU very much scope666! I got a deal with the Z490E Gaming and when I with your EFI all runs perfect except some USB (I have to map them). The only problem I had was when I tried to use the second monitor with the iGPU via HDMI the system crashed. Finally got a RX560 4 Gb and no more...

Hello. Sorry for the late reply: I am still in Sierra. I got a new desktop PC and come back to the forum to get info about install macOS. Even I didnt know about Opencore! After do that, I am going to try to update the laptop. Best regards.

Has anyone tried to activate FileVault? I did the other day on my desktop hackintosh... Only had to put the right drivers for the keyboard in order to can type the password. But here... It will be the same? Or something else? Thanks.

That is a good thing! I think I know how to fix about the wrong kexts. CPU PM I have to work on it... This weekend I will solve. Thank you!!

Yes, sure!! I think I'm not using it but... Just in case :) And if you think I should change something please tell :-) kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext VoodooPS2Trackpad.kext kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext...

Yes, I don't know the size :) Also I searched and couldn't find on Google. At first I used your patch trying to get graphic acceleration after a lot of attempts. But it didn't work because I didn't realise that CoreDisplayFixup.kext is needed for 4K displays. But now I'm not using it :)

All is working fine without using minStolenSize path or your alternative :) Unfortunately this BIOS is very basic and I did not dump it.

Thank RehabMan for your reply. I updated my profile with the resolution :) Luckily DVMT-prealloc looks large enough. And yes, my main mistake was with the 4K screen and not using CoreDisplayFixup.kext I edited the original post to create a sort of guide. Hope it helps someone :)

Hello! Updated: I was close to get crazy. I tried a lot of things (even some of them stupid). But I found this post #386 (thank you @thunderfroggum ) with a very similar hardware and used his kexts and config.plist After that I have full graphics, brightness, battery... I think the problem...

Thank you for your reply. Following the guide for 620 Graphics config.plis I got a Kernel Panic (attached screenshots). Also I attach CLOVER folder used in this attempt. Any ideas about what I am doing wrong?
