Problem with HD 4600

Iura2204 · Feb 15, 2025

Hi guys.
I need your help.
So, I had an idea to install MAC OS Monterey on All-in-One PCS MSI AP200
I upgraded it a bit, installed I3 4360 processor, increased RAM to 16 GB, and have plan install wifi + bt card BCM94352Z.
I created EFI folder using OpenCore Siimplify (added files for Legacy boot) and everything seems to be fine, but I can't start HD 4600 graphics.
Please tell me what to do? What am I missing?
A screenshot of my problem and EFI folder are attached

Ensure you have set DVMT as 64MB in BIOS and remove framebuffer-stolenmem entry from the IGPU device properties. In addition, also remove -igfxvesa from boot args.

Boot argument removed.
I can't set DVMT as 64 MB in BIOS. There is no such function

In that case, set the framebuffer-stolenmem as 00003001

Unfortunately it doesn't help.
When deleting -igfxvesa, a black screen where the apple should be

You need to patch the framebuffer then. Also, you'll need to add SSDT-PNLF for the brightness.
