Trouble Updating 10.14.3 to 10.14.4

[TLM]

I've been trying to update Mojave 10.14.3 to 10.14.4, and OS X Install Prebooter hangs. I ran software update from system preferences, the update downloaded successfully, and the initial part of the install sequence seemed to go fine. Then on restart to complete the install, I tried to run the install pre-booter, and it hangs at roughly the line:

IOConsoleUsers: gIOScreenLockState 3, hs0, ...

When it gets here, the monitor almost immediately loses signal and goes black. Then I have to restart. The recovery drive does the same thing. The main drive still boots and works well.

Searching this site indicates that there is some sort of graphics problem, but I don't understand the differences between the main boot sequence and the install/recovery boot sequences well enough to troubleshoot. Photos and EFI attached.

Thanks!

• I have uploaded CLOVER file Tree and selected config.plist screen captures with some suggested changes annotated, hoping to fix the Graphics Freeze.
• Since Intel HD 630 in different 300 series MoBo need different Ig-p Id, I have left it blank in the image.
  • You may try 0x3E9B0007

This worked. Big help -- Thanks you!

Congrats
Glad to be of help.
Did you have to add the ig-platform-id : 0x3E9B0007?
Did you have to add any Fake ID for IntelGFX in config.plist_ Devices? If so what?

No fake ID for IntelGFX. I set the ig-platform-id to 0x3E9B0007, but I'm not sure if that was necessary. Recovery was booting without the ig-platform-id. Install was booting into the installer and restarting -- at this point I might have just needed to run install again.

macOSMojave 10.14.4 update may have 2-3 reboots through the installer file (depending up on the CPU, RAM and System Disk speed) and I have seen many times kextd stall 'AppleACPICPU' stalling the installation for a long time as if the screen is frozen, before it finally boots and reaches CBM screen ( with installer file disappearing) to boot the System disk to its Desktop. Once the system reaches Desktop after login, the system behaves normally.

After the second episode in one of my computers, I used to leave the system and return after 30-45 minutes to see the Login Screen! I have not investigated the cause of this strange behavior.
