<< Solved >> Catalina easy update and sound fix

[dsener]

I have used someone else's config.plist and is working now. Job now is to figure out what that difference was that made the sound work.

Many thanks for your help

Please report back when you figure it out. It might help someone else in the future! Glad you got it worked out!

Hello, all
Updated 2 machines from Mojave like real Mac (i3-5010/i5-5250, HD5500/HD6000)

2. Delete Voodoo from /Library/Extensions

I can't find /Library/Extensions. How do I unhide it?

It's not hidden. This is how to get to it:
Finder -> Go -> Go to Folder - then type in /Library/Extensions just what is in bold.

Apologies... what was I thinking...

you may need to access your EFI drive. Use CloverConfigurator to mount it

/L/E is not on the EFI drive.

Hello, all
Updated 2 machines from Mojave like real Mac (i3-5010/i5-5250, HD5500/HD6000)

1. Update Clover to Clover UEFI Boot Mode v2.4k r4961
info.plist from working Mojave - no changes
2. Download and install update from AppStore
3. All works fine except sound
Steps to fix sound (works on both machines):
1. Turn off sound hacks in Clover
2. Delete Voodoo from /Library/Extensions
3. Download latest AppleALC.kext and Lilu.kext and put them into /Library/Extensions
4. Search vanila AppleHDA.kext (I found from Mojave) if there is no such file and put into /Library/Extensions
5. The new files unable to work even after the kext rebuild because of the permissions, fix it

sudo chmod -R 755 /Library/Extensions
sudo chown -R root:wheel /Library/Extensions

6. kext cache rebuild

sudo kextcache -i /

Good luck )

Sorry,
but what does this mean?
'turning off sound hacks in Clover'??

I followed these steps and now I’m getting this on boot...

How did you get out of panic during the boot?

Does this work for HDMI sound also? Mine quit working on the update to Catalina.

Worked for me for both HDMI and normal Line Out.
