I've tried practically everything to solve this. After Mac install and the stuff you do after it, the only things I'm really missing are the trackpad "tap" (when a tap on the trackpad acts as a click) and Wifi. I'm going to go buy a USB wifi stick to easily solove my Wifi problem. But I still have no solution for the Trackpad!! I have no options for it under System preferences, even after getting "Keyboard.prefPane" from iAtkos v5i and iAtkos v4i (at least a couple hours of time wasted)!!!! Please, it is driving me crazy! Please somebody just help me. I have the trackpad working fine but the tap click. It didn't work after system update, but after installing the correct kext it worked fine. I even installed the kext twice to see if it would solve anything! Cheers ~Derek
