Q: macOS Sierra - auto restart when watching youtube videos on full screen

After the upgrade, from El Capitan to macOS Sierra, whenever I try to watch youtube videos or any online videos on full screen, the computer just automatically restarts itself, why?? Anybody with a similar problem?

MacBook Pro, macOS Sierra (10.12)

    I have the same problem. Goes straight to the login screen and after I log in, all the apps restart.

    Just downloaded macOS Sierra and I'm experiencing the same issue when trying full creen on youtube or any other window, including Chrome, Browser just crashes, logs me out and resets all open apps.

    Apple, why can't you do something work since the beginning before rolling out such a buggy software!!!!!

    I'm having this issue as well, when I go fullscreen in Chrome for YouTube or Netflix.

     

    Question for you and the others on this thread: Are you using any window management apps like Optimal Layout, to position windows? I am. Wondering if it's that.

    I don't have none of that, so I guess that should not be the problem. Does it happen immediately or can you also watch for maybe 10 seconds after the restart happens? I'm still struggling not to use fullscreen but it just happens when I'm not thinking. Hope it gets fixed soon, glad I'm not the only one with this problem.

    No I'm not using any window management apps either, and it also doesn't happen immediately for me as well. The video is able to play for a few minutes and then all of sudden it restarts without any warning.

    I could get a few minutes as well. Restart happened after maybe 2 or 3 minutes.

     

    In my case, I'm pretty sure it was Optimal Layout. I've quit that and haven't had the issue. Looks like there are a lot of different apps that are causing this behavior in Sierra. (From the ShiftIt github issues page it looks like perhaps Sierra changed things wrt fullscreen apps.)

     

    @vibaza, Try going through your apps and quitting everything (including things that don't show up in the dock or even the menubar; check the startup items as well), then try fullscreen video and re-add apps until it tanks. That's what I'll be doing if I'm wrong what's causing it for me.

    Have an update. I have since re-downloaded macOS Sierra and reinstalled it on my MBA. The whole process as you know its not what you might normally do as its a hassle and time consuming; but I've been testing it for the past 2 days and so far the problem has not showed up again. Im able to watch full screen video on any format and expand any window to full screen without a problem. Still I will wait for the MacOs Sierra update 10.12.1 which I understand its in beta right now. perhaps the update might solve the glitch permanently.

    Hey guys,

     

    I had this same problem too. I'm using chrome so I tried turning off "hardware acceleration" under the advanced settings. It did the trick. Let me know if it worked for you!

    I tried, and it seems to work! Thank you for the tip. I'm going to inform if it still happens after using fullscreen more.

    I agree with themancan. I have the same issue, but not when I am using Chrome (I don't use it). Last time it happened I was sending an email with Thunderbird. Firefox and Excel were running: Firefox was opened on a standard html page and Excel on a simple file.
