Q: Exposé Causing Sierra to Crash and Logout

Hi there,

 

I have noticed an issue with macOS Sierra running on a Mid 2015 15" MacBook Pro with Retina display. Sometimes when I press F3 to access Exposé and my multiple desktops the computer freezes and goes back to the login screen.

 

When I log back in, it is like I have started a new session and the apps I had open start back again but with their sessions wiped. This happens to me about 3 times in a working day, most of the times Exposé works fine. Very strange!

 

Is anyone else experiencing this issue at all?

MacBook Pro with Retina display, macOS Sierra (10.12)

    Hi there, stvwlkr!


    Thanks for reaching out to the  Apple Support Communities! It sounds like you are having issues with Mission Control. I know how important it is to be sure it is working properly. What you might want to try next is a specific restart. Check out this article to Try safe mode if your Mac doesn’t finish starting up. While this article speaks about the computer not starting up properly, it can also run repairs and stop startup items that can cause issues. 

     

    Another option you can try is in this article: How to test an issue in another user account on your Mac. This will allow you to check to see if the issue is user specific or system wide.


    Cheers!

    @stvwlkr - I am experiencing the EXACT same thing you are. Exactly as you described.

     

    It is frustrating to LOSE what you are in the middle of working on! Even though you have backed it up, it is still such a WASTE OF TIME to get everything back to where you were while you were so abruptly interrupted. It is disturbing because it happens randomly, making it difficult to pinpoint the cause. I hope they are able to get to the bottom of this and fix it soon because it is not just an inconvenience but totally derails productivity and headspace because of all the context switching your brain has to do (you go from being in the flow with your work to getting jarred out of it and then yanked into re-setting everything in order to continue on). Augh!

     

    I so regret upgrading to macOS Sierra because of this impact on my workflow... what major pain in the a$$.

    @sterling r - I accidentally clicked on Helpful but didn't meant to. What you proposed above did not resolve the issue. But thanks anyway for the input.

    @stvwlkr - P.S. By any chance are you using an external monitor as well? And if so, is it via DisplayLink? The reason I am asking is because I also noticed that after installing Sierra, my mouse pointer loses its smooth motion and skips when it is on my external monitor. And when I drag Finder windows from the main display to the external display, the windows black out and then slowly materialize into what hey should be. So I'm definitely experiencing graphic issues.

     

    I came across the following: http://support.displaylink.com/knowledgebase/articles/949426-known-issues-with-d isplaylink-on-macos-10-12-sier

     

    So I've uninstalled DisplayLink and am seeing if that will have any impact...

    Hi helipilotchick,

     

    Interestingly yes I do have multiple monitors. I am using a 27" Thunderbolt Display with an Asus USB monitor daisy-chained to the ports on the back of the Thunderbolt Display.

     

    I did originally think this was a display issue because as soon as I type my password to log back in, the screen flickers for a split second and the colours of my desktop wallpaper go inverted.

    Hi @stvwlkr - I have an Asus USB monitor as well. Here is the latest: I uninstalled DisplayLink and then later re-installed the most current version via their website. So far, this has only corrected the mouse skipping and my mouse is back to smooth motion on the external monitor, for which I am happy.

     

    However, the issue of the sudden logouts still occurs randomly when Exposé is used. Hopefully there will be a fix soon so that we can still use our external monitors without problems like this, which as I mentioned above is a pretty big deal considering how it impacts our workflow and productivity.
