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

[Mikorist]

This is ridiculous

FIX for audio (G50-70):

Update AppleALC.kext
Remove "change HDAS to HDEF, B0D3 to HDAU" from acpi patches
Add "alcid=3" (21 or 28) to the boot arguments for layout-id injection
Set Inject to "No" under Audio section
Reboot and success!

Make sure there is no _DSM to XDSM patch in your config.plist in ACPI section.

Use layoutID 28 for best result..

    <key>Boot</key>
    <dict>
        <key>Arguments</key>
        <string>dart=0 alcid=28 brcmfx-country=#a</string>

Also

        <key>Audio</key>
        <dict>
            <key>Inject</key>
            <string>No</string>
        </dict>

and

    <key>SystemParameters</key>
    <dict>
        <key>InjectKexts</key>
        <true/>
        <key>InjectSystemID</key>
        <true/>
    </dict>
</dict>
</plist>

Also when someone tries OpenCore - see that it didn't happen that the boot args ended up in NVRAM ... If so, delete it from there - because if it's wrong there (like dart=0 alcid=11 shikigva=32) you never have sound working - Clover will eject it even after reinstallation.

Another solution is resetting NVRAM with Clover F11

How is your progress with OC?

How is your progress with OC?

When the boot starts - goes in the loop - ACM endlessly tries to register Biometrics and ends with tx_flush: 1028.... and here it stands

maybe @Feartech knows what the solution is?

possible finger print reader? maybe turn that off in the bios if possible

or do you have some software called Docker?

As far as I know my G50-70 doesn't have a finger print reader. There is no such setup in BIOS either. I don't have a Docker. Strange ...

not sure, maybe a network card issue? or lan kext needs an update? (grasping at straws here!)

try booting with your working usb installer and see of kexts needs an update?

Maybe someone can fix it. I don't know right now. Going back to Clover ...

Now it remains for me to do the same through OpenCore.........

Okay, so I just reinstalled my Hackintosh with your EFI folder and it works fine expect the trackpad. It is recognised in the Settings menu with gestures animations but actually the trackpad is not working at all. I had to put ApplePS2Controller.kext to get it working but in this case nothing shown in the Trackpad menu.

You need file in ACPI folder - SSDT-G50.aml - the battery and trackpad won't work without it.
No extra ApplePS2Controller needed.
