I have Fujitsu LIFEBOOK AH532 Notebook which has Sandy Bridge 2nd gen i3 2348M processor ,
with GT 620M, HD 3000 gpus ,i have managed to install mac catalina using opencore by following the guide for ivy-bridge bridge as given at:
i can see my GPU HD 3000 there in mac info with 4mb vram only and HDMI is not working nor inbuilt audio is working
i have tried injecting different AppleALC Layout code: (ie :22,55,180,66)
but none of them is working for my my motherboard usages Audio codec Realtek ALC269 VC2 HD ,
for my GPU i have tried using legacy video patch but no change in 4mb vram
