Successfully installed Mojave 10.14.6. Graphics looks ok and obtained native Full HD resolution, no glitches. Problem is that I need OpenGL and since IGPU didn't allocate VRAM (only 7MB) OpenGL doesn't work. Tested with GLViewer. I cannot change RAM settings in BIOS and tried Framebuffer patching. Experimented will all possibilities I found on Internet. It allways shows Intel HD 4400 7MB. Only Apple Software OpenGL renderer available.

I tried with device-id:0x0412 -> this one destroys screen completely (unreadable).
