I know, I know..I shouldn't have updated it to Sierra until there are patches around but i did and I'm paying for it.
Since the update I see complete system freezes while working with FCPX at least once, twice a day. Not real pattern, sometimes while trimming, colour correction, text editing....I've seen this crash occurred with Lightroom once too. I must add that none of this happened before the update to Sierra so I dont think this is hardware problem?
what procedure should i follow? complete reinstall maybe?
