even thought I have screesavers off, idle timers and energy savers off my iMac logs itself off around every 12 minutes.

 

even when clean my Mac is running or I'm listening to itunes music after about 12 minutes the iMac logs off and shutsdown.

 

I have this problem since november 2012.

 

I am current with my patches.

 

PLease assist with a sollution. No articles with apple support give a good sollution.


iMac, OS X Mountain Lion (10.8.3)

    Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.

    If the problem is still there, try booting into the Safe Mode.  Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart. For each disable/delete, you will need to restart if you don't do them all at once.
