I have a problem, my Mac is so sluggish. when I press on any button,, in most times voiceover is so late to speak.
when I leave it open for 3 or 4 minutes, it doesn't work for seconds until in responds.
even when I press cmd+ f5 to turn on/off voiceover, I have to press it many times until it works.
it's also remarkable that many applications go busy more than before.
is it a bug with Mac OS Sierra? or do I have a problem which has to be solved.
please help me out.
