MBP logs itself out after about an hour

Two month old MBP 15" logs itself out after about one hour, although all energy settings are set to "never." I note someone else had the same problem (posted 12 Sep) but it does not seem to have been answered. This happens whether on battery or charger.

Go to HD>Library>Preferences>SystemConfiguration - find the file - com.apple.PowerManagement.plist - delete it to the trash and open your System Prefs>Hardware>Energy Saver and put your preferred settings in.
I had a problem where it would only stay at 'never'. By deleting and then resetting your settings a new prefs file will be created. See if that works.

  • ITunes logging itself out

    Im getting so tired of iTunes logging itself out of iCloud or Match.   The only way I can get to my songs or content is to go to the iTunes Store, Click account and log in. I then have to restart iTunes and about 5 seconds later, it logs in. After about an hour it logs itself back out again. REALLY getting old..
    Any ideas?
    11.1.3
    Maveric10.9.1

    Open the Security pane of System Preferences and check whether the computer is set to automatically log out after a period of inactivity.

  • My MBP recently started logging itself out.  I narrowed the problem to the external monitor which is connected with a Thunderbolt adapter. When I disconnected it, the problem went away.

    My early 2011 MBP laptop (OS Yosemite 10.2.2) recently started logging itself out.  I narrowed the problem to the external monitor which is connected with a Thunderbolt adapter. I installed Thunderbolt firmware update 1.2, that did not correct the problem. When I disconnect the external monitor, the problem went away. Is there something I can do to be able to use the external monitor again?

  • Audio drops out for about 2 seconds after about 2 hours

    Hey folks....I've been renting HD movies, and I've noticed a bit of a pattern. Three times now, at some point just after about two hours the audio drops out for about two seconds. It's not exactly the same time - on one movie it was at 2:02:26 and another it was at 2:04:18. It's only two seconds, so it's really of no consequence. Just now it was during the closing credits (the music). Before, it was that scene in Batman where the two ferries are stalled on the river.
    Of course, I would rewind to make sure. I use the optical out.
    Anyone else notice this?

    Do a hard reset. Hold the power and home buttons simultaneously until the Apple logo appears.

  • After upgrading to 10.8.3 my Apple USB keyboard stops working after about 3 hours

    Mac Pro 3,1
    OS X 10.8.3 Server
    32GB RAM
    Apple USB Keyboard works fine after reboot (typing on it now), stops responding after about 3 hours.
    I see nothing in Console that looks like the culprit. Here is everything around the last time it happened - between 11:28 and 11:30 they keyboard just stopped working. Unplugging and re-plugging doesn't bring it back. Changing USB ports doesn't bring it back. Rebooting is the only thing that seems to work. Bluetooth keyboard works before and after.

    Hey Doug,
    Thanks for your post, and welcome to the Apple Support Communities.
    I understand that your keyboard backlight is not working upon startup, the following may resolve your issue:
    Intel-based Macs: Resetting the System Management Controller (SMC)
    http://support.apple.com/kb/HT3964
    After performing normal troubleshooting, these symptoms may indicate that an SMC reset may be necessary:
    Lights
    The keyboard backlight appears to behave incorrectly (on Mac computers that have this feature).
    You may also want to reset your computer's PRAM:
    OS X Mountain Lion: Reset your computer’s PRAM

    Note: Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.
    Thanks,

  • I was transferring data from my old iMac to my new iMac via Time Machine. After about 4 hours, the electrical power fluctuated and turned off my wi-fi. Now most of my necessary programs are useless. How do I erase and start over?

    Hello there, LynnS.
    The following Knowledge Base article and it's referenced link should get you started with the Erase and Install of Mavericks:

  • Mozilla firefox start page keeps logging itself on after I close all internet windows I come back and there it is. Why??? Make it stop.

    mozilla firefox start page keeps logging itself on after I close all internet windows I come back and there it is. Why??? Make it stop.

    I've got the exact same issue! I'm pretty sure it just started today too. It's so bizarre because we've all been using Firefox 26.0 for at least a month, right? How could the ''about:home'' page all of a sudden cause this issue?
    I've been able to replicate this issue on a virtual machine running Windows XP SP3, so clearly it has nothing to do with Windows 7.

  • Windows 8.1 automatically logs me out after one minute

    I downloaded and installed Windows 8.1 Pro a few days ago from TechNet. I'm logged in only with my Microsoft account (not a Domain account).
    For some reason, it logs me out automatically after one minute and takes me back to the login screen where I have to click and enter my password in. I checked all of the Power settings and the Screen Saver is off.
    Also, I've wanted to disable the login screen entirely since I live alone.  I've seen many articles about being able to disable it by unchecking the box in the netplwiz app, but the option doesn't even exist.
    Thanks in advance!

    Hi,
    May be you can try to boot into safe mode for test, or create a new account.
    In addition, netplwiz is a command to open Manage User Accounts. I doubt whether you had use it correctly.
    Press WIN+R, then type netplwiz , press
    Enter.

    I booted into Safe Mode (after figuring out the new method) and it logged me out after one minute.  I logged back in, created a new user, rebooted in normal mode, logged in as new user, was logged out after one minute.  Double-checked Advanced
    Power settings again -- nothing indicating this should be happening.

  • Why does I-Tunes log me out after 15min of play?

    I've got 2 profiles set up on the mac, and when the non admin profile is logged in, when i-tunes is running, after 15mins of playback, the profile logs itself out...
    i've checked and the mac has been set to never go to sleep, the screen saver is not due to come on at all and the display has been told never to go to sleep.
    any suggestions?

    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    In the Console window, look under the heading DIAGNOSTIC AND USAGE INFORMATION on the left for crash or panic reports. If you don't see that heading, select
    View ▹ Show Log List
    from the menu bar.
    A crash report has a name that begins with the name of the crashed process and ends in ".crash". It may be under either of the two subcategories, "System" and "User." A panic report has a name that begins with "Kernel" and ends in ".panic".
    Select the most recent of each and post the entire contents — the text, please, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
    Please don’t post any other kind of diagnostic report, such as a hang log — they're very long and not helpful.

  • My OS X Server log itself out automatically

    I’m having an issue with my server: OS X Server 10.4 on my Mac Pro.
    It will log itself out automatically, has done it twice today and the same the other day....
    What could that be?

    Did Applejack cleaning last night... but today the server keeps restarting itself on its own. Has done it twice this morning already and now this pm is shutting down every half hour.
    So the computer came up with a must shut down message and when I restarted, this is the error report that came up.
    PS... have a REV35 disc backup plugged with a firewire cable... is it the source of all thoses prbs ?

  • I tried to update twice and after about 1 hour in step 1 "preparing" it stops and says didn't update. No error messages.

    I've tried to update AppleTV twice. After about 1 hour in step 1 "preparing for update" it stops and says didn't update. Everything works fine except itis not updated. Any tips on what to do?

    Just what do you not understand?
    Did you try:
    Try to restore from another known-good computer and network.
    Error 3014
    This error occurs when iTunes can't reach gs.apple.com in a timely fashion. Follow the steps below to contact the iOS software update server gs.apple.com.

    Install the latest version of iTunes.
    Check security software and ensure that communication to gs.apple.com is allowed. Follow these stepsfor assistance with security software.
    Check the hosts file. The restore will fail if there is an active entry to redirect gs.apple.com. Follow theadvanced iTunes Store troubleshooting steps to edit the hosts file or revert to a default hosts file. See "Blocked by configuration: (Mac OS X/Windows) > Rebuild network information."
    Try to restore from another known-good computer and network.

  • HT204406 some of the songs i have downloaded from iclouds cut out after about 50 seconds? Has anyone else had this problem?

    Some of the songs I have downloaded from iclouds cut out after about 50 seconds when i play them? Has anyone else had this problem and if so did you manage to fix it.
    Thanks

    I've had this happen several times... I suspect the download was interrupted for some unreported reason so it only has a partial file or has a corrupt byte in the file it failed to catch.
    Just delete the local copy and re-download from the cloud and they play fine.
