Hello, I have a Dell latitude D630 with 4gb ram @667 mhz, a T9300 @ 2.50 ghz, an 80gb hdd and I have the model with a Nivida quadro GPU. Currently this computer can boot High Serria at full resolution with functional sound, WiFi, track pad, keyboard, battery monitor, and microphone. But I can’t get the blue track point in the center of the keyboard to work. Also none of the USB ports work properly. I’ve tried several USB injector kext files but none of them worked. I’ve also tried injecting USB through my info.plist file but that causes the computer to crash during boot. Does anyone have a working USB injector kext and a PS/2 kext for the center track point? Thanks for the help!
