Hello Zeltragh,

It's possible your bios is not well configured.
If you want to try my bios settings. Import the CCTK files attached to this message with the dell command configure tool on Windows. I hope it's the last time you use windows on your computer ;-)

I also attach my bios configuration report if you don't have windows on your computer.

Tell me if it works or not

Hi, @zeltragh
Also you can try:
-use another one USB port, if you machine(motherboard) has third party USB controller - use it
-boot without USBInjectAll.kext
-boot without usb fix in clover
-of course you flash drive is working and properly configured for install macOS
-use npci=0x3000 instead npci=0x2000


Hi, @Sylvain83
Are you still on High Sierra?
Please report here any news or changes if occurred...

Hello Yapan4,

I'm still on High Sierra. I wait for webdriver update to put mojave with no hope.

My computer work fine. The only things wrong is some glitch effect on white pages.

There are some positive signals from nvidia, I also expect.

Another one negative's on this apple-native chipset -- FakeCPUID and kernel patches for CPUPM.
We've been looking for a long time to avoid this - no results! You can join.

Hi !
Thank you for your help ^^

Unfortunately the issue remains.

I tried also to update the bios but nothing better.
