Hi there,
Followed this Topic to get things going with my Optiplex 3050 i3 7100 BIOS 1.7.9
After reading this topic i could eliminate Lilu,kext, IntelGraphicsFixup.kext and IntelGraphicsDVMTFixup.kext from my Clover config.
I had one last issue while using 10.13.4, it was terrible screenflicker, after changing SMBIOS to 18,1 it was fixed.
Thank you for helping me out.
