could be many things. Did you check logs ? verbose shutdown ? Is power management ok ? sleep works ? any disk/graphics/audio controller spitting errors ? If using NVRAM, reset ?

Hey ! thanks for your answer. I had seen a post previously, mentionning AALC 1.2.8, but thought it didn't fit with BigSur; so, anyway I tried your file, but I lost all In/OUts on my ALC887/888B... (both on BigSur and catalina) I'm using id 99, only id to get spdif out working here. I should...

Hi guys ! How fast do your BigSur rigs boot compared to older macos ? Here, I have 14 sec for Elcapitan (old enoch chameleon + manual SLE kext patches) 22 sec for Catalina and about 40 for BigSur... (same disk, same Opencore Config, latest releases) Suspecting troubles with appleALC searching...

Hey Antonios, did you manage to patch through opencore ? I'm on OC/BigSur, everything fine but slow boot time (about 40 sec, compared to 22 sec for Catalina and 14 sec for ElCapitan on the same hardware) Suspecting ALC/HDMI ports, I tried to patch AppleHDAController for my HD4600 HDMI audio out...

Thanks. Yes I tried this, but had to pass the "defaults write" commands to actually disable Metal and fall back on openGL. (even with nvidiagraphicsfixup > 1.2.4) sudo defaults write /Library/Preferences/com.apple.CoreDisplay useMetal -boolean no sudo defaults write...

no true progress so far : I'm on a HD4600 + gtx560 setup (HD4600 hdmi working fine.) 10.13.4 brought a slight improvement for me (before it, windowserver was crashing) now I get black desktop, with proper dimensions and layout and mouse pointer, on nvidia ports ; I found someone on a french...

Hi ! I have been struggling with High Sierra and fermi cards (GTX550Ti + GTX 560) I can't get them to work with a HD4600. IGPU works, but nvidia GFXs just display a mouse pointer over a black background... But everything is fine with capitan and sierra.(triple gpu, triple monitor) Another user...

Hi, did you solve that issue ? I have similar problems, this is my first attempt on HighSierra (13,3) and the same desktop config was working fine with ElCapitan and Sierra : triple graphics multiple monitors. HD4600 is set as primary in BIOS (only way to have it working simultaneously with the...

I wake this 6 months old topic, because I have an almost fully working Intel HD Graphics in ElCapitan. At least QE & CI are working. I had graphic glitches in Dock background and windows titles, apparently due to my MBP9.2 SmBios (which I want to keep for Power Management reasons) It's on an...

Hi I know I'm a few weeks late on that topic, but I also have a GTX560 non ti. I configured AGPM properly, and it is working with only one display connected. As soon as the second port is used to plug a second display, the board is working at full speed (AGPM still working, changing states in...

Anything plugged into the usb3 port will freeze the laptop as long as you have "usb legacy" set to enabled in bios. Obviously, you need this legacyUsb option so that you're able to boot from your 10.8.2 installer. The way I did it was to use a simple usb2 hub, and plug both my mouse and the...

Hi, that's weird you don't have neither keyboard nor mouse. keyboard's ps2, and mouse is usb, right ? is trackpad working ? Try another external keyboard, be sure to use it on a usb2 port. try to boot without -x, but with -v, and see where is hangs, if it hangs. try to desactivate xhci (won't...

AH ! if it's like in my bios, you have to go to the 4th menu : "security" And look for something like "lock devices", there should submenus for different devices.

:wtf: ? Nothing related to audio ?? "onboard audio device" for instance...

If it stops on hda, deactivate hda in bios, until you have osx installed and the proper voodoo or hda kext for your soundchip. O.
