After quite a few tries I was able to get High Sierra running on an old i5 3570k/Asus P8Z77-V LK Z77 combo. Excited by the prospect of an easier install on more modern hardware, I ordered a new(er) combo of the i7 7700k, GA Z270X-UG, 16GB of Corsair Vengeance LPX 16GB.
After wrestling with Unibeast/Multibeast, I decided to go as vanilla as possible by following this guide: https://hackintosher.com/guides/hackintosh-high-sierra-10-13-4-update-guide/
I got mostly everything working with the exception of HDMI audio. If the machine goes to sleep the display turns to "colored snow" but I can get the display back if I unplug and replug the HDMI cable.
I have one serious quirk that is really messing with the stability of the build though. Every once in awhile (after 10 minutes, or 3 hours) the machine just flat out reboots. It doesn't lock up, act funny or do anything to indicate anything is wrong. There's zero warning. I think it might have something to do with the external graphics card because I have to go into the Clover and disable nVidia to get it to boot past the login screen. If I don't the machine boots to login and then instantly reboots after entering my password and pressing enter. I've tried a few things including building Lilu and other related kexts from source. The reboot also happened once while I was on the Mac OS native graphics driver. It also happens consistently when running GeekBench's OpenCL Compute tests.
I'm starting to think it might be the PSU. It's an older Corsair 650 which should be enough but might flipping out with its new found electrical load. Before I shell out for a new one does anyone have any suggestions?
