Hey guys.. I have been looking through the forum but I couldn't find an answer. I have a 2010 11'' Macbook Air. Since today morning I am not able to type on my keyboard anymore and also when I click on the trackpad, it always uses the second click for some reason. I tried many things, but no success. Before I could still click on 'Guest' when I was about to log in and for some reason it would bring me to my usual account without even entering my password. However after some stupid settings changing, I can now only type in the username and password and I am stuck here now, as I can't type on the MBA.. I really need to use my laptop again and I would very much appreciate your help in this one.. Thanks guys!!
