I really hope you guys can help me with this one :)


I tried to get my sound working so I removed my applehda.kext (no backup) and replaced with new one which I got from some attachment. Yeah, I'm a newbie I guess. So when I rebooted, my usb mouse or keyboard doesn't work. In booting process there is a yellow text which indicates something about com.parallels.kext USB extension can't be loaded or something. So I can't use any USB devices I think. So that's a problem. How I could replace some kexts so I would get my machine working again?


All help is appreciated!


BTW I use JaSOS if it helps at all.
