Hello dear community !
After many attemps of resolving my problem I can't figure out the cause, so hopefully you'll save my life ! I’ve just completed a direct upgrade from High Sierra to Catalina. I tweaked the best I could my EFI partition to the new macOS version following plenty of guides, and added the required Kexts according to my build:
Build
Mobo: Asus ROG STRIX Z390-E
CPU: Intel i9-9900k
RAM: 4x8 Go DDR4 3200 MHz Corsair Vengeance RGB
dGPU: Nvidia GTX 1080 8Go
Display: Acer Predator Z35 35’‘ 200 Hz
BIOS Settings
-Advanced/System Agent (SA) Configuration:
Vt-d Disabled
-Advanced/System Agent (SA) Configuration/Graphics Configuration:
Primary Display -> PCIE
iGPU Multi-Monitor Enabled
DVMT Pre-Allocated 256M
RC6(Render Standby) Auto
If I plug DP cable to iGPU and set BIOS option Primary Display to “CPU Graphics”, I can’t boot to mac. Indeed, at the end of the progression bar, the display suddenly turns off and the computer reboots.
As I have a dual boot (macOS Catalina + Windows 10 on separate SSDs), and my GPU is no longer supported, I’d like to get a headless iGPU configuration. I would like my monitor to be plugged to the dGPU using DP but iGPU must be working when booting macOS. I’m pretty close to that, everything is booting fine except I don’t have hardware acceleration and my monitor can’t be configured to change resolution or increase the refresh rate in settings.
What’s odd, is when checking « About this mac » informations in « graphics » section is written « Display 16 Mb » as if iGPU wasn’t recognized (Screenshot 1).
But i guess it is because in the system report i can see under « PCI » section the iGPU « Intel UHD Graphics 630 (Desktop 9 Series) », and in IORegistryExplorer as well (Screenshot 2).
Could somebody please help me to get HW acceleration with UHD 630 and 144Hz option for the display with headless configuration ? Please find my EFI folder attached and if you have a question or a suggestion of tweaking please let me know
Thank you in advance !
