Thanks for your help! I'm retiring my 1st hackintosh & took a gamble on a i5-9600k w/ Gigabyte z370hd3
Preliminary install seems good.
Created 8GB bootusb with unibeast 9. Set XHCI to enabled in bios (didn't bother with CSM,VT-d, & etc). Install took a couple of reboots & left 2 additional partitions - recovery, preboot, filevault. Maybe install did not complete. I'll try booting into preboot later. Installed clover, applealc (looks like lilu is installed as pre-req), & def imac 17,1 with multibeast. Finally installed whatevergreen with kextbeast & boot with your config.plist. Looks like igpu is recognized with 1.5GB of vram & sound is coming out of monitor. Yay.
Will generate serial number & stuff before plugging it online. Thanks again.
