    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

    No Go. Lasted ~35 min.
    The 'Reset' is a simple cold boot.

    There is no error message - it's a black screen, like the Mac monitor went to sleep.
