Hello,
My Macbook Air 2013 internal keyboard and trackpad are getting disabled once macOS is loaded.
They're not detected as a USB device in System Report - Hardware.
However both are working fine when I enter boot menu holding option button, or when booting linux os from USB.
So it seems it's a software issue rather than hardware. Any suggestions?
Regards,
Michal
