Parallels 11 IMac late 2013 OS Sierra 10.12.5 Win 10 Just recently - 1 - 2 mo ago - Mac screen goes black out of nowhere. I will be on the Mac, full screen with Win running also. Mac screen will go black - press F6 to go to Win (not in sleep mode) press F6 again back to Mac, screen OK for about an hour - hour & half, then it repeats. Mac is usually active - surfing, typing etc, screen just goes black. See if I can resolve this, then attack who has control of the mouse, cuz it's usually not me. Thanx Ski
