Remove any existing "ApplePS2Controller, VoodooPS2Controller, AppleACPIPS2Nub, ApplePS2Keyboard and old Elan Touchpad" kexts if you have already installed from the HDD '/System/Library/Extensions ', '/Extra/Extensions', and '/System/Extensions/Library/myHack.kext/Contents/Plugins/' (if you used myHack USB installer for OSX).
If you use USB installer to boot (used to install OSX), then you have to remove the above kexts from USB '/Extra/Extensions'.
Install the Kexts (Recommended to use Kext utility for installing) inside the attached zip file using any kext installing methods (In clover, some systems may have problems with kext injection, so try to install them to System/Library/Extensions in that case).
