Mac Os Sierra keep logging out !!

It started happening with Sierra. I wish Apple would chime in because going on a fishing expedition of creating a new user account and transferring all data to it is a large undertaking, for no resolution. If it is a User based issue Apple should be able to tell us what needs be corrected under the covers of hidden files.

It happens when I use a 3-finger swipe upwards to display all the Desktop Space icons across each of my 3 screens. Everything is good so far. Next I move my mouse up to the icons, and at that moment, BING, I am logged out. At that point each of the physical screens has a "home" Desktop Space, the Space that is most to the left. Each of the home spaces then holds ALL the Apps. There is NO logical order. Screen 1's home space may contain apps that had been in a space on screen 3. The only solution is to slowly drag each app back to its appropriate Space, to get working again. There seems to be no problem doing that.

Then I get back to working. In time I want to move a Space that contains debug information nearer to a Space that contains code in an IDE. I do the 3-Finger swipe again and BING, all is lost once again.

Apple really needs to get into this and sort it out.

I have no idea how to fix this issue but transferring data was what worked for me. I also tried contacting support but they redirected me to a more like advanced support then they said they were contacting like engineers to let them know about this issue and they said that they would give me a call but they never did so I left matters into my own hands and transferred the data.

facing the same problem!

Zapping the PRAM fixed it for me:

Reboot holding Command + Option + P + R until your Mac chimes twice.

Hopefully this works for everyone!

Same problem here, it often happens while I am browsing with Safari, especially when watching videos. I think it has something to do with the memory usage.

I'm having the same problem, but on Mac OS El Capitan (i run this because of music production, and sierra isn't fully compatible with some of the stuff I use.)

Is there a cause of this effect/fix?

my "reduce motion" wasn't on...so i guess that's not a fix for me.😟

After few hours after disabling gfxCardStatus 2.3 https://gfx.io ( GPU conntroll app ) no incidents registered.

It looks like this was the case for me, I hope.

And just as I predicted, even waiting 24 hours wasn’t enough. Just back from it logging me out. It definitely lasted longer without this running, but the problem is still there. Sigh...

A Support Group! Yes i love this, so has this issue been fixed? or are we all still thinking about a new login screen design.

Hi James,

Could you give us a guide to replicate the problem on our machines?
