After several days of attempts here, I finally got it to work! The last straw was trying, as someone else already suggested in the thread, ENABLING CSM IN MY BIOS!
I'll run for a few more days and then do a full write-up on my setup and steps taken, but this are the steps I took, in order:
- Had initially installed
10.13.1;
- Had everything working there until the
Supplemental Update installed itself without my consent. After that, black screen;
- Tried updating to 10.13.2, setup constantly failed;
- Re-downloaded the High Sierra setup on my other Mac (had to remove the file and request a download again);
- Re-built the pendrive with Unibeast 8.1 and the new, updated High Sierra setup;
- Did the installation procedure with that pendrive,
"over" my previous 10.13.1 installation;
- Success, 10.13.2 (17C88) was installed with no hassle, but the black screen issue persisted;
- Booted without the NvidiaWeb flag, the web drivers
automatically offered to update to the latest compatible version;
- After installation,
still black screen;
- Tried literally every fix in this thread: cleared my
nvram.plist on EFI, updated
Lilu and the
NvidiaGraphicsFixup kexts, had them both on /Library/Extensions, /System/Library/Extensions and /EFI/CLOVER/kexts/Other, patched the Apple graphics kext using AGPDFix (1.3), played a bunch with system definitions;
- Settled with
iMac17,1 (installed via MultiBeast), still wasn't working
- Decided last-ditch effort to enable
CSM (UEFI Only) on my motherboard; once rebooted, the BIOS/bootloader display moved from my primary HDMI video to my secondary DVI video, then worked!
- Success!
My setup:
- ASUS ROG STRIX B250F Gaming (it was hell to get audio working here!)
- i7-7700K
- EVGA GTX 1060 6GB
- 16GB DDR4 2400mhz
- Samsung EVO 960 250GB NVME M.2 (the only reason I didn't give up and went back to Sierra early on)
I've attached my EFI folder, and here are the files in my /L/E folder:

Wish you all the best of luck
