Trackpad not working on Lenovo B570

1 post in this topic

Recommended Posts

I installed Mac Os Lion on my lenovo b570 using a guide at http://www.insanelymac.com/forum/index.php?showtopic=269586&view=getnewpost


I used the retail version because iatkos l1 didnt really work for me. Right after the installation my trackpad was working fine. After I installed the dsdt provided by the guide the trackpad is not working and in the system preferences it says trackpad not found. I reinstalled mac os lion multiple tries trying to find the answer but i couldn't. I don't know why my trackpad doesn't work. I also tried reinstalling the voodoops2 controller and apple nub kext but that didnt help either.


The only way to navigate is by using a usb mouse.

can anyone help me?
