my macbook pro's key have been playing up since this morning. i don't know if its hardware or software problem.
when i press any alphabet keys on the macbook it either mutes or un mutes the macbook. it is very random. sometimes pressing 'r' 'k' or 'c' mutes .
i have restarted my computer a few times but in vain.
just wondering if anyone has had same problem or has any solution.
