hi there, 
i installed everything just how you told me to, 
i rebooted after updating permissions with kext utility, i tried out the touchpad but my cursor was doing weird stuff. 
when i touch or move the touchpad the cursor went up and down, it also pressed all kinds of buttons when i was only touching the trackpad. 
does somebody have an idea on how to solve this ? 
Sorry for my bad english, i'm dutch  
  
Greets !
