firstly: thx for this great page!
Don't really know, if it is the right category, but here is my problem:
installed mackintosh zone yosemite on my dell vostro 1520, everything was fine. But when I tried to use the integrated touchpad, it blows my mind. it randomly skips around the display, never giving me the chance of clicking something. using an external mouse, i was able to install, but problem remains. so i tried rehab mans voodoops2 release (installed as in tut). repaired permissions, rebuild cache and restart. suddenly the integrated keyboard and trackpad did not work at all. so i plugged the extern one, wrote the old ps2controller.kext over via kexwizard, rebpair, rebuild, restart but the prob remains.
anybody has got an idea how to fix my skippy touchpad? would be great, if needn't to carry a mouse with me all the time.
