    When I startup iMac retina 5K I always see a little glitch every time when startup iMac
    But everything work fine.

    Video glitch at 0.2 sec


    Is it hardware or OS glitch ?

    Should I Worry About This or Should I ignore the glitch ?

    Take it easy...

    It's not a hardware issue. We have a lot of members reporting the same thing. You could see some glitchs at shutdown too.

    It's scarry, but it's software related. In the next update it will be fixed. I'm running the Beta of Sierra and have no more glitchs.

    If everything else runs fine, I wouldn't worry.
    Could just be software, while the OS loads up.
