ok maybe we should try an old rehabman acpi wake trick.

Add this SSDT and in the config ACPI->Patch

Same behavior as before. Doesn't wake up.
 
you did both renames, _WAK to ZWAK and _PTS to ZPTS?
 
Also you can try this version of WEG, (you may need to downgrade to LILU 1.5) , I compiled it adding modForceWakeWorkaround.enabled = true; for Skylake iGPU.

Yes, forgot to expand for the print screen.

It crashes mid boot with LILU 1.6, 1.5.9 and 1.5.

Meanwhile I decided to post here https://github.com/acidanthera/bugtracker/issues/2044 about everything we tried and someone is speaking about hibernation mode 25 but I'm unsure on how that should be applied.

Thank you.

I got that part, it crashed when I tried to put it to sleep. Restarted to a RTC error.
 
Try with the WEG kext above, and lilu 1.5, and remove the extra boot flags, also remove the PTS-WAK stuff above.
Reverting back to as clean as possible and only this one patch on WEG.
Use lilu debug version and try to get a full boot log (even if it crashes)

Same thing.

Any other specifics logs you need? Thank you.
 
Only other idea that comes to mind is to go back to regular WEG and try faking device-id for Kabylake. Skylake and KB are very similar though so the wake issue may still be there.

So keep the same info you have under AAPL,ig-platform-id
but add a new entry under it for "device-id"

KBL:
  • 0x5912
  • 0x5916
  • 0x591B
  • 0x591C
  • 0x591E
  • 0x5926
  • 0x5927
  • 0x5923
I'll hunt for skylake mac mini acpi tables to see if there's any clues in acpi, but I believe the issue is with the skylake driver itself, and without help from the dortania team, knowing what to patch where is beyond my skills.

Okay I was reading the beginning of the log and it says " "[IGPU] Failed to wake the ME: reload=0, retries=50\n" @IGGuC.cpp:1695" > not sure if ME means Intel Management Engine but I went into the bios and enabled it. Restarted the machine and time the screen turned off mid boot but I was able to SSH. It didn't crash!

Tried to sleep/wake with caffeinete and plugging the display again - no luck,.
