I'm using Niresh, Mavericks, upgraded to 10.9.3, on a Dell Inspiron 15R SE (7520). I simply can't get my touchpad to work. None of the kexts around there work, not even the "Elan kext" thing here, although my touchpad is supposed to be Elantech. The weird thing is, it worked in the installer. I tried to search the installation USB for the kext but I couldn't find it. Can someone please help with that?
