Q: Mac Os Sierra keep logging out  !!

Fixed.

Turn hardware acceleration off in Chrome's advanced settings.

So far noone has the fix to the issue yet do they

There is no universal fix at this point. The problem primarily involves crashing to the login screen when going to fullscreen for apps, or video (including in iTunes), or animating between Spaces. There appear to be variations as well so we don't all have exactly the same problem.

A variety of fixes have worked for some people, some permanently and some temporarily.

Installing a program called Little Snitch permanently, so far (several weeks of heavy use), resolved the problem for me, due to something Little Snitch did during installation (not the program itself), though I don't know what that was. Several others have reported success with this, but many others have reported no success. I have worked with Apple Support on this issue for weeks, sending them multiple logs, and they do seem to acknowledge that this is an issue. I was promised a "hot fix" a few weeks ago but haven't seen anything yet. Perhaps it will be fixed in 10.12.1.

For people who've had the problem exclusively with Chrome, turning off hardware acceleration in Advanced Preferences seems to be a fix. It was first posted on Reddit.

DuetDisplay has known conflicts with MacOS Sierra. If you have DuetDisplay, which lets you use your iPad as a separate display, you may want to look into this.

I've also seen fixes posted that are related to Razer products and other third-party hardware and drivers as well. The problem does not, however, appear to be limited to a particular Mac—iMac vs MacBook vs. MacBook Pro—or configuration.

One of the things to try is to create a "test" admin account. If the problem does not occur in the "test" account, that would be consistent with others who have this problem; some have suggested migrating all of your stuff to the new account. This can be done, and is probably a true fix, but is no fun.

10.12.1 cannot be that far away. You may want to try to hold out a bit longer.

For the record my forced logouts have never been connected with anything full screen or changing spaces.

It seems that there are many ways to hang up the GPU and any of them will result in the window manager crashing shortly thereafter.

I have the same issue, usually happening when I watch YouTube in full screen.

I noticed that the ssh-agent is not running any more after the forced logout but I don't know what that could mean.

Very annoying issue indeed.

I found that the ssh-agent is not running after I am logged out for some reason, do you think it is related with your plist intuition?

I have this similar problem. My iMac logs out spontaneously when on Safari reading. This happens occasionally and is very annoying. I have tried all the suggested steps with no result. Help.

Same problem with my Mac OS Sierra update. Was working perfectly until I updated to this iOS, and keeps logging me out whenever I watch full-screen videos or launch full screen applications.

Please fix this problem

Experiencing the same issue here as well.

Please help!
