At the outset I would like to thank Mikorist for his brilliant effort with OC. I only wish I had seen this post earlier!

I have a stock G50-70 with Atheros AR9565. Had challenges in getting the trackpad and wifi to work earlier.

With Mikorist's EFI, I am able to get Catalina 10.15.6 working with all features except trackpad, WiFi (AR9565) and Audio jack auto sensing.

#1 I had to use ApplePS2SmartTouchPad.kext to get the ELAN trackpad working as VoodooPS2Controller.kext (ELAN specific) didnt work properly.
Query: Am I missing something?

#2 Was able to get WiFi (AR9565) working by using corecapture.kext, CoreCaptureResponder.kext and updating IO80211Family.kext in S/L/E.
Query: Are 'BrcmBluetoothInjector.kext', BrcmFirmwareData.kext, and BrcmPatchRAM3.kext required for Atheros WiFi?

#3 Using the VoodooHDA.kext, the jack auto sensing doesnt work. Have to manually select output as 'Headphone' after plugging the headphone. It used to work using AppleALC in Mojave using Clover with the usual configuration.
Query: Anyone else facing this issue? Is there anything else to be configured?

Thank you

Edit1: #1 Resolved after changing ApplePS2SmartTouchPad.kext back to latest ELAN VoodooPS2Controller (v2.1.5)

#3 Resolved after replacing VoodooHDA.kext with AppleALC.kext.

No, those kext are for broadcom (brcm) wifi chipsets

Thank you!

Have you been able to get Trackpad/mouse working in the OpenCore (v0.6.0) GUI?

I upgraded to OC 0.6.1 and opencanopy.
Catalina 10.15.6 works almost flawlessly.( no audio jack auto sensing)
Actually working on SSDTs fix to allow windows boot using OC, Linux boots fine adding an Entry in Misc -> Entries

Audio jack auto sensing worked for me after using AppleALC (both 3 and 28 work but don't know which one to choose) instead of VoodooHDA.kext .

HDMI audio output works (unlike VoodooHDA) but no volume control for HDMI.

Although slightly higher audio level and mic gain would have helped.

I vaguely remember that I was able to boot into Windows using OC without any additional configuration!

I have mic issues when using AppleALC.
OC injects SSDTs when booting windows and this causes issues.
With my EFI I was able to boot Big Sur installer. Anyone updated yet?

Anyone have Z50-70 OpenCore instructions / kext / driver list worked up yet? Any example stock config.plists on GitHub yet? Would be nice to see a solid EFI GitHub release made with config info. Been running OpenCore on other systems with tremendous success and overall quality of life improvement so far...
