Update about trackpad.
So trackpad gestures and scrolling work when using ApplePS2Smarttouchpad kext from
https://drive.google.com/drive/folders/1dMEQja8X3pfXTrmqImQ8L2M1zjp1RDhC
It kinda works well, gestures are also supported (4 finger gestures to open and close stuff , vertical and horizontal scrolling too)
the main problems with this kext is
1) Mouse acceleration is bad. and no sensitivity control in sight, in fact there is no trackpad settings at all, it won't ask you to connect a trackpad but it will be blank
2) This kext breaks 2 things in our keyboard that are fine in voodoops2controller , it breaks brightness control in f2/f3 and caps lock is weird, it is not dependent on the indicator light, it takes 3 presses to switch from uppercase / lowercase
I think maybe voodoops2keyboard extension + appleps2touchpad combo might do us fine. audio wise I fixed it using voodooHDA. however note that the gains need to be modified, it is not as loud as it should. nothing that can't be fixed.
everything else on the build is doing fine, even stuff like palm rejection is working. bluetooth works with BluetoothDevBroadcomInjector
p.s : again all of this was done on Mojave and not high seira as the post initially was about
