asus z390e-gaming + 9700k + uhd630 - black screen on install

Hi All,

Video log at bottom

I've done a fair bit of research, but it seems like not many people have posted about this motherboard which makes resolving this issue a little complicated. Here's the problem: I'm trying to get to the install screen for mojave 10.14.5, but I am getting a black screen before getting to the actual installer. The USB drive seems to still be working, after the black screen (it's responsive to keyboard input I think). There's no clear kernel panic before that.

So far, all my changes have resulted in a similar log output and end result. I've tinkered with a hackintosh before and gotten a golden build, so hopefully I have all the useful information listed:

Parts. I apologize in advance but this build is for a friend, so the parts are different from those listed in my profile.
CPU: i7-9700K
GPU: None / UHD630 (iGPU)
Mobo: Asus z390-e gaming
SSD: HP EX900 M.2 250GB PCIe 3.0 x4

BIOS Settings (I played around with numerous combinations of these changes to no avail - exact same log):
Latest bios
VT-D: Disabled / Enabled
Intel (VMX) Virtualization Technology: Disabled / Enabled
Legacy USB Support: Disabled / Enabled
Above 4G Decoding: Disabled / Enabled
Primary Display: CPU Graphics
iGPU Multi-Monitor: Auto / Disabled
DVMT Pre-Allocated: 64M / 128M
RC6(Render Standby): Auto / Disabled
XHCI-Handoff: Enabled Disabled
WiFi Bluetooth: Disabled

What I've Tried:
Switching from Displayport to HDMI on Mobo (and checking cables are plugged)
Various BIOS Settings - see above
Booting with Safe Mode on Clover (different error, just freezes)
SMBIOS: iMac 18,1, iMac 18,3, Macmini 8,1
UEFI Drivers: Swapped AptioMemoryFix.efi for OSX
Using USB 2.0 slot

Would really appreciate some help, hopefully others stuck with this motherboard have gotten past this

Hi were you able to get this fixed? I have the same configuration as you, could you please upload your config and EFI?

Try using a clover folder from the guide linked to my build signature, just change the port limit patches.
There are two main SMBIOS used for Coffee Lake:

• iMac19,1 - For Mojave and newer
• iMac18,3 - For High Sierra and older

Thanks for the help Big W I was able to make it to the installer on my installation but I get stuck at 2 minutes remaining with the "Disk is not convertible to APFS" error. Even tried using another NVMe drive I had lying around, no luck.

Could it be changing my SMBIOS to iMac19,1 will fix this?

Here is my EFI folder:

If you are using Samsung 970 Pro nvme drives, you may need to update your firmware. If you have a bootable windows drive use Samsung Magician software to check and update as necessary.

Thanks for responding Big W, firmware is up to date as per Samsung Magician. Even tried a no-name brand NVMe drive with the same results. Do the kexts I have look good?
