I think you got me wrong. I am not trying to install Mojave. I already install and everything working. When I change my primary GPU to IGPU on Bios with these ig-platform-id, I cant boot.
Just ran across this post:
You may need WhateverGreen 1.2.8 to fix kernel panic with Kaby Lake and 10.14.4.

Thanks Casey! I finished my build by your excellent and thorough giude.

One question, I have LaCie Thunderbolt 2 thru AppleTB2 to TB3 adapter pluged in, but the disk is shown as Internal. Any clue how to make it external?
We went through a period of externalizing our internals (apologies to gory horror movies) and didn’t quite reach a conclusion as to whether it matters. Are you able to eject / hot-swap any of the drives in the LaCie enclosure? Does the system sleep and wake properly (or it displays a string of “disk not ejected” warnings)?

If you search this thread for “internal enclosure Thunderbolt” you may find those posts.

Thanks, I'm looking forward to it.
Please test the attached file by copying it to the CLOVER/ACPI/patched folder in the EFI partition of your Mojave SSD and rebooting.

Thanks but I have i9900K I think this is CoffeeLake right? And I am already using the latest version of WEG.

Anyway I used these settings and I can boot without any problem with IGPU but I choose these settings and set to primary GPU;

398481


398482


398483


398485


But when I tried these settings I am getting kernel panic. I must learn how to set up the headless mode.

Everything working here now with 10.14.4!

For h.264 encoding, I ended up using shikigva=60 boot flag as other users here. Just tested a live streaming to Vimeo, 10k video bitrate over ethernet >>> flawless with plenty of headroom on my i9-9900k to run other things during broadcasting.

Only thing I noticed, my Geekbench Metal Score got a little worse (it was around 143k and now is 138k). Adobe Media Encoder got some more seconds to render same content I used to test.

Anyways, thanks Casey and everyone here sharing experiences :)

In one of your previous posts you attempted to use Kaby Lake platform ID and device ID, hence my reply.

Anyway I used these settings and I can boot without any problem with IGPU but I choose these settings and set to primary GPU;

In order to set headless mode:
  • BIOS --> IGFX --> Enabled.
  • BIOS --> Initial Display Output --> PCIe Slot <N>.
  • Platform ID 0x3E980003 for 10.14.4.
  • Device-id (do not specify) for 10.14.4. Just delete "device-id" parameter.
  • Delete all of the framebuffer-con* parameters. The IGPU will not display video, so no video connectors should be specified.
  • Sysdef = Macmini8,1 or iMac18,3

hi CaseySJ,
i am doing the installation and can't erase the target Mojave disk. in disk utility there is 2 disk showing up:
my usb (with Install macOS mojave as partition) and an other "apple disk image media". when i try to erase the install mac os, it say "couldnt unmount disk". if i try to unmount it first, it refure to unmount.
The other disk isnt available to be erased.
What should i do?

Do not erase the "Install MacOS" disk because that is your USB install disk.

What disks are listed under Internal on the left side of Disk Utility?

Do not erase any disks under External.

not erasing external make sense, got it.
In internal are listed all my hard drives (2 HDD, 2 SSD, 1 nvme) and nothing else. i displayed "show all devices"

Hi @CaseySJ , so if I update to 10.14.4 do I need to change the platform ID or will it work straightforward with the previous build? (iMacPro 1,1)
