[Guide] Intel Framebuffer patching using WhateverGreen

Yes it would. Wondering why you didn't pick the 16,2 SMBIOS which is the closest match to your CPU. It used the Iris Pro 6200 graphics.

Thanks again for the quick response! I originally tried using 16,2 but in instantly kernel panics (something with USB, right at the beginning of the boot process), 14,4 boots but GPU is still stuck@300 :/ I'll see if I can find out what's causing the USB issue, maybe 16,2 would fix it.
[edit] fixed the USB issue (XHCI was badly set in BIOS), 16,2 booted but GPU is the same slow

Hello to all

I got this Mac mini clone (HP ProDesk 400 G3 mini) to work perfectly on all fronts only thing that I can't seem to get working is the secondary DP port.

So these are the specs:

i3-7100T
Intel HD 630
8GB ram
(using iMac18,1 on Opencore)


I tried following Tonys threads for a similar computer, and few others but nothing seems to work. Tried this on Catalina and Big Sur, and all the same result. The main DP works flawlessly and the secondary is black.


Tried to patch the frame buffer, and specify buses and connectors and nothing works, is maybe spoofing my iGPU a solution, if so what do you recommend .

can someone please try and help me.

Try disabling AGDC with boot argument igfxagdc=0 or device property disable-agdc.

My head hurts from all the hours I have spent trying to get my uhd 630 working on big sur 11.2 with opencore 0.6.6. Can anybody help me out? My motherboard is the Asus Maximus XI Code.

You might get a better response if you took the time to:

• Describe what settings you tried already
• Posted your config.plist with serial numbers removed
• Mentioned what exactly you want to do with the UHD 630 (is it to enable HDMI output or just to put UHD 630 in headless compute mode)

If the UHD 620 is properly activated in macOS and the only issue is the screen resolution being locked to a maximum of 1024x768, then please try SwitchResX from here. There is a free trial period.

To determine if UHD 620 is activated, simply run IORegistryExplorer, scroll the device tree on left side to IGPU@2 and check if the first child node is AppleIntelFramebuffer.

Hi guys! Great community here, I want to send a big thank you to everyone involved!

I recently installed Big Sur and I have an issue with my secondary display - everything works fine if I connect it after a few minutes after I login to macOS, but I cannot boot the system with both displays connected - if I do this, both of my screens start flickering.

I read some of the posts I found here, but I'm not completely sure about what I need to modify in my config.plist - something related to connectors for sure.

I have 2 DELL monitors, main one is connected via hdmi, second one via DVI. I am attaching a few screenshots from IORegistryExplorer, Hackintool and my EFI zip. Thanks in advance!

Hi guys!

Help!! I am able to sucessfully boot into Mac OS Big Sur (Kaby Lake)but whenever the system starts and boots the apple logo after completing the bar (below apple logo) it enters into no signal mode(use hdmi cable) for which I have to turn off monitor and turn it back on by which lets me enter to password screen of Hackintosh. SMBIOS 18,1 is what i am using if i use SMBIOS 18,3 this problem does not arise but the colour scheme goes out of control and shows blue as orange and all blue color items get displayed as orange.

So in short I have to turn my monitor off and turn it back again whenever I boot or reboot.

did you try MacMini 8,1 symbios ?

Sorry to ask a counter question but will it be fine to use MacMini 8,1 SMBIOS as its CPU is Coffee Lake where as I am using Kaby Lake??
