Hello, i’m having an issue with my dad’s 2013 13” MacBook Air. He just opened it up as usual and found a black screen with some notifications on the side. I forced shut it down using the power button, then powered it back on and was able to get the login screen, but the keyboard and trackpad were unresponsive. So I tried it again and am getting the same results after shutting it down. I tried a PRAM reset as it seemed to be reccomended for a similar issue; but this has not changed anything from what I can see. As I said the power button works, but the keyboard and mouse (via trackpad) are not working on the login screen. What’s going on here? Just looking for some help please, thanks, Jer.
