Replace the touchpad kext voodooPS2Controller with this one

The fix was also offered in that thread from takiller if you read through the whole thread.

As for Wifi, your DW1506 is atheros based so it's no longer supported after Mojave. You'll need to replace IO80211family.kext from Mojave after installation.

See here for more info. There's an alternative on the last post to inject rather than replace.
