Hi. I just started experimenting with a High Sierra boot on 960 EVO NVMe formatted as HFS. The boot time is very slow, 5 mins maybe more. Boot seems to take a normal amount of time with the Unibeast USB plugged.
[UPDATE]
For those with slow boot issues or generally anyone who wants to do a clean, stable High Sierra installation on similar builds, here is a mini-guide based on my build and the experience I had so far:
Turns out High Sierra isn't that stable on my system after all. As I tested it for a few days I experienced freezes where only the mouse cursor was moving for a few seconds until eventually graphics on screen started going crazy, flickering and flashing, parts of the UI going black....a mess!
I wasn't performing any graphic-intense tasks just browsing, but I still suspect this to be a graphics issue so will test again once I get a discrete GPU in the system but also wait for a couple of updates on High Sierra before switching to it as my main boot. For now going back to a stable Sierra boot.

- If you installed High Sierra on APFS I would suggest to move to HFS as a first step, as it's more stable. You can do that by using two hard drives to clone the APFS installation to a freshly formatted drive, SSD or HDD, either will keep whatever structure you format them after the cloned High Sierra installation is copied over therefore opting out of Apple's APFS. Ideally the installation should be cloned vanilla, soon after the first boot if possible, while still on USB drive "life support". You may have to manually install Clover bootloader to the destinatiion drive.
- Start fresh with config.plist but also kexts to identify the absolute essential ones and keep them all in System/Library/Extensions. Make one change at a time as it makes it easier to identify what goes wrong when it does.
- Fake SMC plugins will break your build. I learned the hard way so I had to use another boot drive to remove them from S/L/E.
- For Kabylake users, no more spoofing as a Skylake due to native support on High Sierra, so a lot of the 'Fake' kexts for CPU, GPU etc are not needed except of course the FakeSMC kext
- As of the time of writing I would avoid using MultiBeast until the one specific to High Sierra is released.
- Native Power Management fix by @RehabMan should always be high up on your list of fixes on a fresh installation.
- Injecting Intel and adding boot flag -disablegfxfirmware in Clover Configurator along with IntelGraphicsFixup.kext in S/L/E should do the trick for using on-board Intel HD 630 graphics on similar builds to mine.
- Even though my ethernet worked natively it stopped when I fixed HD 630 (A bit like whacking a mole ) Intel Mausi kext in S/L/E not only restored it but shows up 'en0' and picked up as built-in which means, with the right SMBIOS setup in Clover Configurator, App Store works unlike on my Sierra setup.
