Hi guys,

Got this macbook air with very strange problem.


Trackpad and keyboard only working if you but with OPTION. While you are on boot device selection all is working fine. Once you select what u want boot it stops working.

First i tought it was software issue. But bootin from usb, from other hard drive got exactly same problem.

Anyone faced that kind of issue?



P.S.solved. it was trackpad. Still cant understan how it works in boot menu and not working in OS.

Before loading OSX drivers, trackpad/keyboard work on USB mode.
Once entered into OSX, SPI mode is activated.
In case if file vault is activated, trackpad/keyboard still work on welcome/password screen...
