[initial success] Skull Canyon NUC

You're not using SSDT-IGPU. Clover does not read SSDT-IGPU.dsl (and it wouldn't work anyway). ACPI files must be compiled as AML.

Use 'make install' and report back.

Also, please provide only EFI/Clover (as requested in "Problem Reporting"), not entire EFI folder.

Ooops, alright, I'll see if I can make that happen.

Hmm, scrambled graphics > black screen.
About this Mac now says Intel Iris Graphics P580 1536 MB.
Should I do all the things mentioned in problem reporting again now?

Doesn't make sense... will need to see "Problem Reporting" files.

SSDT-IGPU injects 'model' = "Intel Iris Pro Graphics 580"

How do you get About this Mac result if you have a black screen?

Should I do all the things mentioned in problem reporting again now?

Always.

Always.

That was after rebooting with USB installer attached

Not useful.

Let's go back to without SSDT-IGPU.aml. Set config.plist/Graphics/Inject/Intel=true and experiment with different ig-platform-id values. Reply with ioreg for each successful test.

I will need to verify your reporting of the results are accurate...

I would like to see the same with 0x193b0005 (if it works). It seems to me that 0x193b0005 does not work.

Note: You can still gather ioreg in the failed/black screen case if you enable ScreenSharing and connect via VNC from another computer on the LAN.

I think I'll change SSDT-IGPU.dsl to 0x19160000 for now, until we have better data. DONE. Please test...

0x193b0005 worked again
