[Guide] Lenovo Z50-70/Z40-70/G50-70/G40-70 using Clover UEFI

Hi
My audio disappear after using mic after sleep (using AppleALC)
I've my CodecDump from Linux and I want to know how did you convert the PinConfigs from CodecDump to add them to AppleALC.
Thx

You have PinConfigs.kext in AppleALC source - in folder Resources

You can delete all others in list and just keep your codec

Also you need to delete all codecs in PinConfigs.kext list - and make your own.

Open CodecDump from Linux - select all - copy - import from Clipboard

and then save into PinConfigs.kext - For HDMI - and Audio card
separately (in same PinConfigs.kext )

HDA Hardware Config Resource should look like this.You need to chose LayoutID - i kept the original 28

            </array>

after that you go to to build AppleALC

config.plist for Clover or OC

You will see the same PinConfig configuration in Hackintool - if it works properly

Thanks a lot.
That's really helped

I did it. G50-70 OpenCore Full....First I want to thank everyone here.

I especially want to thank @the-braveknight - without him I would not succeed in this, also RehabMan, @Feartech and acidanthera with his guidance from here

After all this has been studied and learned, Clover looks like an easy pie. No kidding.

What works:

Special function keys working, trakpad gestures(all listed in MacOS) , HDMI video/audio digital out works, speakers working, Headphones working, WiFi, Bluetooth, USB2/USB3, built-in mic and camera, power managment, battery status, graphics including OpenCL, Ethernet, Mac App Store Working.

A guide would be nice, with a proper guide I'd be able to make the post-install scripts work with OC

I have extra BIOS menu unlocked - and I changed ASPM to L0s for PCI Express Root Port 4

How do you unlock extra BIOS menu?

Thank you

nope, you can only use intel integrated gpu

I will certainly do as soon as this corona madness passes ...

Sorry...just a little question....this GUIDE of yours is not useful to perform a fresh install of Catalina on my Lenovo?

 

[syndacate]

Ok...I tried to follow this guide....I can not even obtain the boot from USB key. Only a black screen. I installed on the USB key all the efi packages and kext as requested but I had no luck. Somebody can help me please?
