Mountain Lion keeps logging user out...

I have just installed Mountain Lion. In 30 minutes of using it, I have been logged out to the login screen roughly 12 times. All at completly random times. This is very vexing as this will make a completely unworkable environment.


Is anyone having the similar problem!? What could the issue be?

Mac Pro, Mac OS X (10.6.7)

I had the exact same thing. Right after applying the latest software update to enable Power Nap. I would log in, then it would restart all these previously opened apps. Once it finished opening everything, it would log out right away. I got like 1 minute each time before it would log out. I just rebooted the machine, instead of logging in again...that seems to have fixed it.

I would assume that something in that user account is not compatible with Mountain Lion which is causing it to crash. You can find out more in the logs by going to Applications/Utilities/Console

If you are unable to create a new user account because its crashing. Enable root user following that link above and see if its happening there

so if safe mode then that means that a 3rd party(most likely) is causing that crash. You can check it in the logs via the console in the utilities folder


but if it doesn't then that simply tells us that something is wrong with that user account. Creating a new user account would dive us deeper into finding what's the culprit. Whether its a user account issue or a system wide issue
