All of sudden, my MacBook Air isn't responding to keyboard commands--restart, shutdown, force quit applications all don't work. When I try to start an app, nothing happens or a window flashes on the screen that says the app I'm trying to access interrupted restart. That window flashes by so quickly I had to keep trying so that I could read the window contents. There were choices there, but the window disappears too quickly to do anything. Any ideas what happened and what to do?
