Was still working on getting the system up and running, didn't cross my mind to move the kexts over. Also completely overlooked the SSDT-PNLF not being an aml file. Both issues fixed and the issue still remains. No control over screen brightness and a black screen upon first boot for the first few minutes and then the backlight turns on.

Updated problem reporting files attached.

As per guide, ForceKextsToLoad is only for pre-install. After install, it should be removed.

Make sure you rebuild caches and reboot.

Other problems:
- you're using the wrong Clover. The Clover you're using has a serious ACPI patching bug. Use latest RehabMan Clover as linked from the guide.
- CsmVideoDxe not recommended. Remove.
- EmuVaraibleUefi not recommended. Remove.

Also, read post #1 regarding EDID patching that may be necessary.

When everything is working correctly with your kernel cache and patching, the ApplePanels under PNLF->AppleIntelPanelA should change to ApplePanel with just the F19Txxx entry.

Kexts were installed to L/E and kext cache rebuilt in my last post, but I rebuilt cache again anyways for this time around. Updated Clover to your latest version, patched the EDID and removed CsmVideoDxe & EmuVaraibleUefi.

The good news is, I have brightness control now and the keys on my keyboard are mapped properly and work. So that's a step in the right direction!

But I still have a black screen with no backlight at all at first boot for about 3 or so minutes. I attached an updated problem reporting file for this one as well.

It is not a unique problem for you... others have the same issue.
No known solution at this time.

All of you with that specific problem should participate in a thread that is specifically for sharing information on that exact topic. I don't know that anyone has created such a focused thread yet. Perhaps you should do so.

There are also those with UHD, following the same guides here, that DO NOT have that problem. You might compare notes with those folks.

Beta branch merged into master yesterday (for both). Use master.

Have used this but my screen takes 2min to boot up but the external screen, w/ nvidia, boots up straight way.
