pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD 6600 XT

No, its an LG 38GL950. A beast of a screen. The black screen issue didnt happen on the first few boots when I got the monitor so I thought all was fine on the hackintosh side. Too late to return it now (~6months). Aside from this one issue its been great. like i said not a single problem on windows which is why i struggle to see how it could be hardware.

Kind of kills the creativity when i load into osx to work on some beats and have to reboot 5-10 times before i see a desktop. Don't get me wrong i like a good troubleshooting project, but like you said with the inconsistency of the problem it is proving hard to isolate what is really happening. All I've really accomplished so far has been to update my kexts (which stopped black screen from happening prior to the machine finishing booting), but the problem persists after boot - sometimes at login screen, other times a few seconds after logging in.

You can try with the GTX 1080 pulled and just use IGPU to see if it's the Nvidia drivers...

popped video card out and getting system crash during boot, tried inject intel and nvdriver=0 bootflag. crashing at about 70% booted each time. anything special i need to know to get the igpu running?

You are on High Sierra, right? I forgot when UHD630 support was added... Try using 59120003 to config.plist > Graphics > ig-platform-id and InjectIntel.

yes high sierra, is that something I can do in clover settings prior to boot? currently trying to do it on my usb recovery key + boot from that. would this string replace the 0x000000 in injectintel?

Yes, you should be able to do it from the Clover boot menu. I don't remember exactly which menu it is though...

Or, the following should work.

no worries the recovery usb is extremely slow but i got in and got it done. attempting to boot in a min here.
just curious in my default settings is it just InjectNvidia that should be selected? not nvidia single/generic/noEFI?

edit -
-when booting off the usb (using clover to apply the settings) i get an instant crash
-when booting from internal drive and manually applying those settings i get either an instant crash or a visual artifact and no ability to get in via remote desktop + system eventually reboots.

I think at the time I did the build your guide said that the onboard graphics didnt work. wouldnt that mean i would need a newer build of High Sierra to do this?

Don't inject Nvidia anything. Maybe that was your problem...

Try using EFI 4.3.2 from post #1.

Do you mean that might be the problem with my original config- the occasional black screen?
or do you mean that might be the problem with the igpu
^and wouldnt this be fixed by just changing the nvda_drv=1 to a 0 in the boot args (same result - instant crash on boot)

I meant, Injecting Nvidia may have been the cause for problems when you had your Nvidia card installed.

hmm so i popped the 1080ti back in and disabled InjectNvidiaGeneric (not sure why it was on) and it has helped all 3 things but not solved:
- occasional black screen on boot seems to happen much less (so far 3 times in about 18 reboots- a couple times it went dark then came back as if adjusting resolution)
- unplugging /replugging the monitor still causes the issue
- sleep / wake still an issue, switching output ports sometimes fixes when it happens, other times the system is 100% frozen on wake.
- "put display to sleep" function in energy saver seems to work now as opposed to causing the no signal issue.

Thank you for your help chef this is definitely an improvement. Do you still think it is hardware? im leaning towards some kind of an nvidia webdriver issue with support for this resolution maybe. (works fine on my 2013 macbook pro with Mojave. thinking i will test on upgraded 2010 el cap macpro next just to make sure its not an osx problem)
