i visited this site and it requires me to remove the older kexts like voodoops2 and appleps2 before installing these, however i cant do that, cuz i cant find where the kexts are. if i use the kext without removing these, no gesture works and the cursor is very slow. What should i do? Plz help, my ultimate purpose is to get the advanced touchpad gestures working.
