[GUIDE] General Framebuffer Patching Guide (HDMI Black Screen Problem)

Can anyone confirm if the latest update fixes the no HDMI on the Maximus XI Hero Call of Duty Edition?
Not sure what you mean:
  • Latest update? You mean macOS 10.14.4?
  • No HDMI? Are you trying to activate the on-board HDMI port on your Maximum XI Hero?
  • Because you have RX 560, it may be best to configure your OS in headless mode where iGPU is active, but used for compute operations only such as H.264, HEVC, Quick Look, Preview, etc., but will not drive a display monitor.
 
Hi.
Wonderful guide @CaseySJ. Thanks!
My problem is my IGPU does not show properly in Hackintool. It's not recognised I believe
the build I'm working on is Gigabyte Z390 M Gaming/i7 8700k/high Sierra - I have both DVI and HDMI monitors the plan is to have a discrete card and one monitor attached to each. I'm first trying to get the IGPU to work and then the DPGU
Below are my files.
Any help would be great. have been working on this for 2 days, read a number of threads. idk what's wrong
thanks a lot

Hello @joanareis,

Please try the attached CLOVER folder that fixes the following issues:
  • Gigabyte Z390 motherboards work best with OsxAptioFix2Drv-free2000.efi in combination with slide=0 instead of AptioMemoryFix.efi and OsxAptioFix3Drv.efi. (Note: You had both of the latter memory fix drivers in your drivers64UEFI folder. Only 1 is allowed at a time.)
  • Blanked out IntelGFX and ig-platform-id from Clover Configurator --> Devices and -->Graphics. The iGPU is configured via WhateverGreen instead (Devices --> Properties).
  • Added a few more ACPI fixes.
  • Enabled "trust" checkbox in SMBIOS.
  • Modified Boot arguments.
These fixes should help with shutdown/restart as well.

Please check your BIOS settings as well:
  • IGFX --> Enabled
I noticed that you don't have a USB port limit patch in Kernel and Kext Patches. If you're running Mojave 10.14.4, you may add the 3 patches described here:
But the best long term solution is to create a custom USB SSDT by following the new user-friendly guide here:

Quick reply, I replaced the clover folder with the one you sent. didn't work, still 7MB vram and glitches
One of the last lines I see when booting is
"Graphics driver failed to load: could not register with framerbuffer driver"



btw BIOS settings IGFX is enabled
thank you

Ouch, that doesn't sound good. Are you running Mojave 10.14.4?
 
sorry high sierra. thought that was in my profiles
My Hackintosh experience began with Mojave so I'm hesitant to offer advice on High Sierra, but from previous posters in this thread, I believe we need to spoof device ID to Kaby Lake:
  • Platform ID = 0x59120000
  • Device ID = 0x5912
These changes have been made in the attached config.plist. Use at your own risk! :)
