Q: Mac Os Sierra keep logging out  !!

Same here.

I installed Little Snitch (Free Trial version). After install was finished (restart and initial buch of windows/settings), I uninstalled it.

Haven't had any log-outs since. Hope this keeps it fixed.

To download Little Snitch:

I'm downloading Little Snitch now and will report back my results.

In addition to the other symptoms previously described, is anyone also have issues with "Preview", especially with manipulating PDFs?  Prior to the Sierra download, I could do menial tasks like combining multiple PDFs into one, filling in forms fields, etc. without too much trouble - and something mind you I refuse to pay Adobe hundreds of $ to be able to do for a full version of Acrobat.  Since Sierra, Preview has been acting very strangely, locking up after any PDF manipulation and requiring a restart of the program, only to find the action that I wanted to accomplish actually was done but I couldn't see it prior to close and restart/reopening.  I have no idea if these are separate issues from the main logging out issue or not, but thought I'd share and ask.

For those who don't want to go through the hassle of Little Snitch installation/de-installation (though I kind of like having it, so I kept it), this is a response I received from the developer. It's a terminal command to update the boot-cache. I used this on my laptop yesterday (it didn't have the problem but I figured, "What the heck?") and it didn't appear to cause any problems. I'm still focusing on the permissions issue because macOS Sierra removed the ability to repair permissions, and I've fixed a lot of problems in the past by repairing permissions.

If someone is adventurous and wants to try this, it could be all that is needed to fix the Spaces/Fullscreen problem. Note: It takes a number of seconds (20?) and all sorts of text will fill your Terminal window; do not freak out!

I would restart after running it before trying to go to Fullscreen.

If anyone with the Spaces/Fullscreen problem tries this, please report it back here. If it works, I will report it back to Apple Support; it may help them fix the problem at the system level.

Here is the response. You can simply cut and paste the sudo touch command, but you will have to put in your Password at the next prompt to get it to run:

thank you for your request.

 

I would assume fixing the permissions for the /Library/ folders does not interfere with your issue, but since Little Snitch updates the boot-cache in order to install its own kernel-extension, it might be the effect that some corrupt system kernel extensions are updated coindicentally.

 

You can trigger a manual boot-cache update via the following Terminal command:

 

  sudo touch /Library/Extensions/ && sudo kextcache -v 6 -update-volume /

 

this probably reveals some errors in case.

 

On the other side, if this is an issue of kernel extensions it is a bit odd that it only happens on certain user accounts. This would of course more lead to the assumption that some preferences at ~/Library/Preferences/ are to blame, but the Little Snitch installation does not alter any other plist files in there of course.

 

Hope this helps at least a little.

 

Best regards,

If you're asking me, the answer is: Sure. I already have a case open with Apple Support and Apple Engineering. You can refer them to me.

I tried Little Snitch and it still happened, but I turned off Rapport (trusteer) and the problem went away. Turned it back on and it recurred. Rapport was installed by one of my online banks, but I think I can do without it. Any, thanks to all, especially Dhalgren.

Hmmm, seems the Little Snitch thing doesn't solve the issue.

I started getting the issue again. I tried a re-install and uninstall of Little Snitch, but no joy.

I also tried the suggested:

sudo touch /Library/Extensions/ && sudo kextcache -v 6 -update-volume /

But I actually got a log out right at the moment the script was done running!

So I guess it's back to square one for me.

Again, I do not have the issue when not using an external monitor. So the solution for me is simply to work of the laptop screen instead.

I have, reluctantly, and after trying many solutions that worked for others but not for me (including Snitch), decided to just set up a new user and migrate everything from old to new. If you use Time Machine that should be a lot easier for you (http://danfrakes.com/2015/01/04/how-to-duplicate-an-os-x-user-account/); I don't, so I've been restoring from Mozy and reestablishing preferences, but it hasn't been as bad as I thought because of KeyChain and iCloud importing much of the most critical things like saved passwords, etc. I am mostly up and running now, and no issue with desktop spaces, full screen apps, etc. Once all done, will remove my old glitchy user. Just be sure that if you do this you make the new user an admin! Yeah, it was a huge time-suck. But it is DONE.

So did your solution fully work? Considering taking the time to do it, if you are getting a solid result.

I am having this issue too it's driving me insane. Going to try the chrome hardware fix.

EDIT: This workaround works for now but we need a real fix.

The new user I set up works great: none of the issues I and others have described in this thread. Works exactly as it should. It has taken me (is still taking) a lot of time to restore files from Mozy, and some preferences have to be re-established of course (like trackpad behavior, email signatures, etc.), but yes: setting up a new user and migrating from old user does work. And a lot of things I expected I'd have to re-do from scratch or migrate manually I didn't, like keychain, safari credit card info, contacts, etc—anything tied to your apple ID that iCloud stores.

Well... total failure for me. I installed Little Snitch this AM. Upon reboot, my MBP wouldn't recognize the Intel HD graphics driver. I tried resetting NVRAM and SMC to no avail. On the phone with entry level and senior tech at Apple support for over an hour to no avail. They said to nuke it all and start over with El Capitan.

Suck.

hi sadly i installed LS and yet i proceed to have the problem and i uninstalled and now i don't know what to do. i hope apple gets an update soon. very disappointed of the update.

i just did the command and now i will restart. i will try full screen and report back here.
