[Solved] High Sierra Gives a Black Screen with White Apple Logo

[astrobruin]

P.S. For reference, here's a list of my kexts. We have similar builds, so it may be helpful. However, I have a non-native graphics card (which is a pain) so it's possible you don't need some of these:

/Volumes/EFI/EFI/CLOVER/kexts/10.14/
NVWebDriverLibValFix.kext *
Shiki.kext

/Volumes/EFI/EFI/CLOVER/kexts/Other/
AppleIntelE1000e.kext **
BrcmFirmwareData.kext
BrcmPatchRAM2.kext
FakeSMC.kext **
Lilu.kext
realtekALC.kext **

* you may not need this
** added by Multibeast

Links to some of the non-Multibeast kexts I use. Again, I don't know which of these you may or may not need, but if you had them in your original El Capitan build, you may want to try them out.

Lilu 1.2.3

I also installed this to my S/L/E directory. If you install it, do not manually copy but place it on your desktop and use kext Wizard or similar to install it. Otherwise you can break your build!

NVWebDriverLibValFix.kext (don't know if you need this)

Shiki 2.2.7

BRCMFirmwareDate.kext 2.2.10
BRCMPatchRAM2.kext 2.2.10

High Sierra also requires a new apfs.efi file, but I believe that's probably in your USB's EFI directory. But just for good measure:

✓ 3. Copy apfs.efi to /EFI/CLOVER/drivers64UEFI/
