Thank you!
Tested this Clover folder and it seems to be working well as I have the exact same specs as him. Only thing is that sleep still doesn't work - it wakes up with only a black screen. Does it work for you?

Thank you.
I had SSDT-PNLF in my Clover folder already but was missing your AppleBacklightFixup.kext to accompany it. Downloaded and installed the latest release from your BitBucket (replaced SSDT-PNLF in patched clover patched folder and put AppleBacklightFixup.kext in clover Others kext folder).

Unfortunately after restarting I get A KP on boot. Attached is a picture (zip because I don't know if uploading the pics directly would compress it)

"Problem Reporting" files are incomplete.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

Okay, had the same issue and this is how I fixed it
-Delete WhateverGreen.kext if you have it installed, since you're on Mojave, UHD630 should work natively, as they work on mine.
-Put EmuVariableUefi-64.efi in drivers64UEFI (this I dunno how, actually fixes sleep for me, when I remove it, I can't wake the system up!).

Hey thanks man for this, but it didn't help me
Could you attach your Clover by any chance?

Sorry for the of-topic , but is UHD620 supported native on Mojave , too ?

What is the device-id?
There are a couple of different "versions" of "UHD 620".

 

[DimitrisG]

Not sure. How to find that ? My laptop is a Dell 5570 with an Intel i5-8250u (coffeelake).

Look in ioreg, under IGPU, device-id (assuming you're not spoofing), in 'compatible' which is generally not spoofed.
Or look in your Clover bootlog (look for 'GetDevices'... notice list of PCIe devices and their identifiers).

Please note that your CPU is not Coffeelake. It is Kabylake-R. Refer to Intel specifications:

Using your config_HD615_620_630_640_650.plist

 

[RehabMan]

Using your config_HD615_620_630_640_650.plist

Your device-id is 0x5917.
Note no native support in Mojave:

NUC6i7KYK:~ rehabman$ grep 0x5917 -R /System/Library/Extensions/
NUC6i7KYK:~ rehabman$

(no output indicates pattern not found)

Hence fake device-id 0x5916:

NUC6i7KYK:origin rehabman$ grep 0x5916 -R /System/Library/Extensions/
