Everything's working perfectly for me, thanks Rehabman. I've got nvme drive - it was very slow on initial startup but after a couple of reboots no issues.
There are some warning messages popping up before the Clover menu. I presume they are not cause for concern? I have no idea what they mean!

Those are just logs from apfs.efi as it starts.

Seems, I found an interesting thing - did High Sierra dropped a support for the SATA controller integrated into Skull Canyon's PCH?
Look on two screenshots - one is Sierra and High Sierra. NUC6i7KYK is loaded with two SATA SSDs. One sees that, another doesn't
If I replace one with NVMe Intel 600p, then High Sierra sees it.

As per guide, SATA-100-series-unsupported.kext takes care of the missing SATA controller support for both Sierra and High Sierra.

I have no SATA devices in my NUC6i7KYK now (both are PCIe AHCI or NVMe), so I disabled the SATA controller in BIOS. But when I had it enabled, I noticed that the wrong SATA kext was loading. The generic SATA driver works for some, but not others (on laptops usually SATA-100-series-unsupported.kext is required). I think you'll find SATA working if you use SATA-100-series-unsupported.kext.

In the post-install scenario (eg. with SSDT-NUC6-SC.aml), the difference is handled in ACPI instead of with the SATA-100-series-unsupported.kext. Refer to SSDT-SATA.dsl if you're curious.

Overview

The purpose of this guide is to provide a step-by-step guide to install High Sierra (or Sierra or El Capitan) on the Intel NUC6 series NUC mini computers. My NUC6 is the NUC6i5SYK, although I expect the guide will work on other similar models (any NUC6)..
Hi Rehabman, I have updated 10.13 smoothly following your guide. But when I shut down or restart the os, there will show a sharp green screen before it become black. I have checked the Lilu.kext and IntelGraphicsFixup.kext is the latest edition.

Another problem is as you mentioned, there is a preboot option in clover start menu.

Regards

Peng

Yup. I see the same green screen sometimes. It does not seem to cause a problem.

I see the green screen all the time, when restarting and shutting down. Also those apfs.efi message appearing when booting my NUC.

Since it's not a cause for concern then i will ignore it.

Can I safely remove the Lilu and IntelGraphicsFixup and any other kexts from my /L/E directory? I'm not really sure what they're for

Just a quick question.

Does sleep works? The reason I am asking is that I am running Windows 10 Pro insider preview/macOS Sierra/macOS HS in a single m.2 Samsung 850 250GB Evo SSD.

When I am in the Windows OS and put my NUC to sleep, I observed the screen is garbled so I will do a shutdown by pressing the start button. Wonder if it could be an hardware or software issue.
