I was cleaning my rMBP with a damp cloth with a little isopropyl alcohol in it and when i turned it on now i cant type anything! A few keys work 1 out of 10 times only and the caps lock key is contantly on, even when the macbook is off! What do i do? Isopropyl evaporates really fast, and it has been 15-20 min and it still not working, is this permanenent? I will wait more but has anyone ever had similar experiences in the past?
