Can't get gestures to work on Lenovo B50-80 touchpad

[SemoB 0]

Hi,

I've just installed macOS Catalina on my Broadwell Lenovo B50-80. I managed to get everything working except for gesture support for the touchpad. The touchpad itself works (clicks and moves with one finger) but when I go to Preferences, Trackpad, it is not recognised there and so I can't use any multi-touch gestures like scrolling, zooming etc.

I believe my touchpad is an ELAN (I had ELAN drivers in Windows). I've tried different Voodoo PS2 kexts but I haven't managed to get gestures to work at all.

I've tried to attach my RunMe output file and my Clover folder to this post for further information, but it says the files are too large, so here's a link instead.

Please any help is appreciated. Thank you.

Also I think my DSDT is OK but any help with DSDT/SSDT is appreciated.

Can you provide some guidance on this please? How do I determine the correct PS2 Kext for my trackpad? What process do I need to follow? Thanks.

Thanks for this. If I remove VoodooPS2Controller my keyboard stops working. How do I make sure this doesn't happen? 

EDIT: I went on and removed VoodooPS2Controller and used your attached kexts on its own, and now I have gesture support and my keyboard works just fine. Thank you very much, Maldon!

Update: so, while using this kext fixes the trackpad issue, it also broke my brightness controls, which previously worked with VoodooPS2Controller. What can I do to fix this @MaLd0n? Thanks.

@SemoB or @MaLd0n, Can you please share your EFI Folder? For me the installation is went good. But it is not booting up after clover boot loader installation.

 

But if i booted with the USB drive which i used to install mac, it is booting successfully

I'm not using that computer any more. Have you gone through the process of copying your EFI from your USB to your hard disk's EFI partition?
