Cease macOS from freezing throughout sleep/wake on a Catalina Hackintosh

This information ought to resolve Catalina from freezing when a hackintosh is waked from sleep when operating off the Intel iGPU (built-in graphics). The mouse will freeze a pair seconds after being waked up and  there could also be a sudden restart with a kernel panic message saying there was an issue with Intel HDMI audio while you boot again in.

I seen this kernel panic solely occurs when these circumstances exist:

• Utilizing AppleALC.kext with Clover (AppleALC is not being examined on Clover because the developer moved his help to OpenCore inflicting this difficulty)
• Solely occurs when Intel graphics is enabled.
• When the show monitor doesn’t have an HDMI audio output (This kernel panic occurred to me on a monitor that didn’t have audio system, however after I plug in my different monitor that did have HDMI audio with inbuilt audio system the kernel panic goes away)

To get round this difficulty we disable HDMI audio with a HDEF patch. If you’re utilizing the EFI information within the primary Catalina information this patch has already been included.

1. Obtain gfxutil
2. Open downloaded folder and Proper-click open  gfxutil
3. An inventory will populate discover PCI0.HDEF and replica its PciRoot system path
   

   In my case the system path I would like to repeat is PciRoot(0x0)/Pci(0x1f,0x3) as its on the identical line as PCI0.HDEF =

4. Open config.plist situated in your EFI folder with Clover Configurator
5. Choose Gadgets column in Clover Configurator
6. Choose the drop down menu and choose No or kind it within the field is within the high proper nook of the Gadgets web page
7. Choose the Properties tab close to the underside of the Gadgets web page
8. Click on the “+” signal below the Gadgets* desk
9. Paste the system path you copied from gfxutil
10. Choose the System path thats been added to the desk and add:
11. Click on the “+” signal below the Properties desk to the best
    

    Properties Key*	Properties Worth	Worth Sort
    No-hda-gfx	AAAAAAAA AA	DATA
    alc-layout-id	1	NUMBER

    

12. Restart to use modifications and see if sleep works after.

I’m my testing this difficulty solely occurs when utilizing AppleALC on a monitor with out audio system over built-in graphics. Different methods to avoid this difficulty could be:

• Switching your EFI to OpenCore or by utilizing a distinct audio answer than AppleALC.kext.
• Switching to a monitor with audio system inbuilt so the panic doesn’t happen.
