Q: macOS Sierra crashes to lock screen when playing videos on fullscreen

Hi All,

 

Soon after I installed macOS Sierra on my MacBook Pro (Retina, 13-inch, Late 2012) I noticed that my laptop crashes to the lock screen immediately while I am watching videos on fullscreen especially YouTube and Facebook Videos via Google Chrome. I've reinstalled the os multiple times but the problem still persists. Is there any solution to resolve this?

MacBook Pro with Retina display, macOS Sierra (10.12), null

    First, check to see if you can create a test account, to determine if it just occurs with your account or throughout the system. If it just occurs with your account (test account works normally), you probably have the same problem as the rest of us. I've been working on this for a couple of weeks with Apple Support and posted about this on another thread you posted to. I hope to hear something from Apple, based on logs I sent them after we had tried numerous other fixes, this week. If so, I will post it.

    I'm having the exact same issue. When I log back in everything loads up and Chrome goes to full screen. It happens on pretty much any site I've used with videos.

    If the problem is limited to Chrome, some have reported, originally on Reddit, that turning off hardware acceleration in the Advanced Settings (within Chrome) solves the problem. If you are having a more general problem with fullscreen or space changing causing a crash to the login screen, I've posted a possible, somewhat workaround-ish, fix here:

     

    Mac Os Sierra keep logging out !!

     

    It has worked for several people. I'm posting mostly on that thread even though there are several other threads, like this one, that appear to be focused on the same, or a similar, issue.
