MacBook Air does not respond to cursor clicks

Solution 1:

First I would look if any of the running apps is doing that.

Press 3 keys together

alt + cmd + esc

In the new pop up window use the up or down arrow on your keybaord and when selected hit Enter key.

You can Force quit anything showing in there.

If that did not help to restore normal function use again the keyboard to Restart.

To reboot your Mac instantly, hit Control-Command-Power/Eject.

Alternatively if you hold the power button for 2 seconds a screen should show up asking you what you want to do next.

Solution 2:

I had the same problem a few minutes ago. I was undoing my action in iMovie when this happened. It started to overheat soon after.

To fix this I held the power button for five seconds to shut it down hard. It restarted and everything was alright after. I didn't lose the data on the iMovie file.
