Hello, my daughter pressed some keys on my mac book pro and it started talking/commenting everything i do, it says what page it is, it reads whatever is written on the page, whatever i type. I cannot get rid of it She did it before and restart solved the issue, but this time it didn't work. Can anybody advise how to switch it off? also if you know how to block the keyboard or some anti-baby trick to save the mac till she grows up i'd be greatful! thanks!
