my MacBook Air keyboard not working
I bought a Macbook Air (13 inch) today. In first 6-7 hours it worked perfect, I transferred things from my old laptop,, instal some apps and even write a doc. no problems. After a notification, I upgraded the IOS. When I opened it up and entered my password, but when I logged in and tried to actually write the password the keyboard did not react.
I tried restarting the laptop, but it wouldn't help. if I try to write I need to press 5-10 times on a key, sometimes it works from the first time. If I want to write 'orange' my keyboard type for eg. 're' or 'one'.
besides that, the laptop works good. What should I do?
Help is much appreciated.
MacBook Air 13", macOS 10.15
