I don’t know if I am being hacked Basically I wanted to open my MacBook Air and when I started writing in my password all letters were in all caps. Therefor, I plugged in my keyboard and it worked on the email Registration but not on my password. I am wondering if someone might have hacked my password and if so what I could technically do to stop him. This is a very urgent problem as I need this laptop for my school work, thank you for anyone answering.
2-3 hours before this happened a small ball fell onto my keyboard
What you have described are not the symptoms of a hack. It sounds like something is broken on your keyboard, and something was dropped something on it. You will need to get the keyboard physically repaired.
