Give this a try, replace the Config.plist and kexts folder Audio layout-id is set to 11 If still no audio, try these different one alcid=13, 22, 28, 44, 66, or 99. Reboot after each change Archive.zip

Post a copy of the EFI and IOReg file using IORegistryExplorer.app v2.1

try setting NVRam at OC picker, hit the spacebar to see the option

there's a tread about it here. if you have the same specs, give it a try with the attached files

here you go, just change the serial, MLB, ROM and UUID. I've never use OC Configurator but from just trying it out, I noticed it upgrade the config file to OC 0.8.3. So if your OC files is still O.7.9, you will encounter error. So either update the rest of your files to OC 0.8.3 or whatever version OC it shows when you launch OC Configurator, or just use OC configurator to generate the serial, MLB, ROM and copy them to your Config file manually. Personally I use Plistedit Pro. You can use Xcode or maybe ProperTree as well. config.plist.zip

Yes

there's 3 areas that you need to change System Serial number, MLB & ROM You can use Hackintool.app as well to generated for the model you're emulating

did you make sure it has unique serial #, etc..

look at the device properties and smbios of this Clover config for an Optiplex 9010 AIO with HD4000 Maybe it might work for you too config9010.plist.zip

That's why you should post your full system specs and EFI folder as requested.

start with posting your full system specs And attach your EFI folder for review

attach entire EFI folder what wireless device does it have?

Attach the OC files you're using

Please post your fix, might be helpful to others with the same model
