For no apparent reason my key B got unresponsive. Model A1502 with scissors keyboard. Already tryed removing key with mechanism and blowing everything with air but haven't got any results.
What to do?May it be software problem?May reinstalling macOS solve it?Or shall i just go to service and replace the keyboard?
MacBook Pro
Does an external keyboard work properly? If so, then the built-in keyboard has a hardware failure.
