Jake.C Posted September 3, 2023 Share Posted September 3, 2023 (edited) Hi there, I've installed Mac Big Sur on my desktop PC. My graphics was recognized as Intel HD 4000 5MB so I fixed VRAM and it changed to 1536MB. Before I fix VRAM I had output simultaneously on both VGA and HDMI ports of my mainboard (both connected to one monitor). But after fixing VRAM, VGA output keeps on showing verbose and freezes just before Mac's loading screen and it continues only on HDMI output. I can see a distorted verbose screen on my VGA output when restarting too. (There's also another problem seemingly shown up after fixing VRAM. Copying files is super slow, and sometimes copying a ~12MB folder takes up tp 50 mins.) My Primary graphics is set to iGPU (64MB). I use Open Core 0.9.4. I've tested changing connectors to VGA using Hackin tool but no luck. As my monitor has 2 inputs (HDMI and VGA), I need to connect HDMI to my GTX 950 and VGA to intel GPU on my mainboard. What can I do to make my Mac continue using VGA?
