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

[Mikorist]

Maybe my config only works on other Z50-70s?

I have no idea.. Because the RehabMan guide for the laptop with the HD4400 shows a different configuration.

I managed to get rid of all graphical glitches I had on my z50-70 by changing the AAPL,ig-platform-id to 0c00160a in Mikorist's config. Seems fine to me ATM, I'll test around some more.

Hi StStefan, i have a z50-70 laptop, i7-4510u, hd4400, clover and whatevergreen latest versions.
In 10.15.4, if I connect hdmi cable my laptop go to kernel panic during boot, if i power on laptop without hdmi cable works. In 10.15.3 it works even if I connect hdmi cable. Can you help me?

Go to BIOS - put full UEFI mode there from Legacy mode

download my EFI OC 0.5.8

good luck

p.s.
Monitor will work over HDMI when you see the apple logo before logging

All work great with this EFI folder except the TrackPad which is not working at all. Do you have any solution for that?

I've reuploaded EFI.zip again.
Download again. Delete NVRAM - in the beginning.

Give some pictures of laptop

Trackpad is working great again! I’m currently using Mojave as the in-built Wifi is working with it.

I still have graphical glitches with this last EFI
With both Discrete or UMA only in bios

Edit:
using

<key>AAPL,ig-platform-id</key>
<data>DAAWCg==</data>

as @StStefan suggested
solved any issue and allowed me to up VRAM to 2048 too

Hi Mikorist, I have tried your EFI config, no kernel panic during boot but laptop display glitches.
Thank you anyway

enable cms/legacy in bios

enable cms/legacy in bios

Hi Feartech, if I enable cms/legacy in bios with hdmi cable connected laptop goes to kernel panic during boot.
If I enable UEFI mode in bios with hdmi cable connected laptop works but internal display glitches.
Thank you.
