My Macbook Air just shows the lit screen with nothing on it. The mouse does not respond. Nor does the screen change. How can I reset to get the Air working again. 2012 model with the latest software updates.
My Macbook Air is totally unresposive once it is turned on. It has 256 GB of flash memory. No mouse cursor; the keyboard has no effect. Running the battery down and then plugging in does not fix this. What can I do to get the Air back?
