Middle row of keys on MacBook keyboard suddenly became unresponsive
The middle row of letters keys on my MacBook don’t respond at all—letters a-l and the modifier keys in that row. Does this indicate any particular reason/cause of the problem or a likely solution? The other keys work fine. A non-Apple external keyboard is working for now, but it’s cumbersome, so I would like to fix the built-in keyboard.
