My computer has been spontaneously restarting itself.  This last time I wasn't even at the keyboard, I was across the room.  I don't know what to make of it, completely baffled.  I'd love some help on this, and if it could come in layman's terms I'd love it even more.

Hi ...
Try Troubleshooting the MagSafe adapter
If the Mac freezes, it may be a preference setting.
Check System Preferences > Energy Saver
See if Restart automatically if the computer freezes is selected. If it is, deselect that box.

  • I have an ipad3 which has been spontaneously restarting and is not connecting well to either mobile service or wireless networks.

    I have an ipad3 which has been spontaneously restarting and is not connecting well to either mobile service or wireless networks. It has become unusable. Is there  a software update to fix this issue?
    I have tried removing and reinserting the sim card - I am not even being asked to put in the sim pin to unlock the sim
    I have reset the network settings and reconnected to my wireless network. I can get onto the wireless network but the ipad does not connect to my carrier even though my mobile phone (same carrier) has great service.
    It seems to me that due to the connecton issue the ipad then restarts itself so I cant even use it for the local apps that do not require any connection to run because every few minutes the unit reboots.
    heading to an istore tomorrow to have it looked at but wondered if there is a software upate or setting I can change myself to fix this isse.
    not happy after the cost of the unit and ony had a few days use before the issues started!

    Thanks Alan,
    in the end it was replaced at the Apple iStore, they restored factory settings and it was still playing up for them too. Weird but the replacement is working perfectly!!

  • My computer has been seen at Genius bar 6 times for freezing up, reloaded all original settings and even went to the apple shop where they replaced the battery and logic board. Still freezes after I try to reload iTunes stuff and app stuff from apple

    my computer has been seen at Genius bar 6 times for freezing up, reloaded all original settings, all of their diagnostics, and they even sent it to the apple shop where they replaced the battery and logic board. Still freezes after I try to reload iTunes stuff and app stuff from apple, especially iPhoto which is seems to refuse to load and then begins freezing up all over again. Anyone else have this problem. Other than this, I have had absolutely no problems with this computer. Now, it's a file of junk.

    Hi Ronald ...
    Have you checked lately to see how much free space there is on the disk? Especially since iPhoto freezes at launch ...
    Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage
    Make sure there's at least 15% free disk space.
    And make sure the OS X software is up to date.
    Click the Apple  top left in your screen.
    From the drop down menu click:   Software Update
    If you have anti virus software installed or are using third party Mac cleaning utiliites, that may be part and parcel of the your problems.

    If you see this symbol in the status bar, it means that TTY is on.  Choose Settings > Phone to turn TTY on or off.

  • Word with Friends keep freezing. so i re-install it for it to update, several times.  This last time it didnt install but my ipad2 shows it was.  How do I resolve this issues.  Thanks for any suggestions.

    Only when i go to a different browser (like IE) after i clear it , then all that shows up is the pages i visited in IE , that is what bugs me , why is IE browsing history sowing up in Firefox ??
    Basically , i can clear the history in Firefox , and then for a example , go to Craigslist , using IE7 (launching it from a complete different Icon , in other words at that time i never open Firefox) , then after closing out , or even leaving open as it does not seem to matter , i go into Firefox , and hit History , and there is every place i visited in IE7 , on my History in Firefox

  • My iphone 5 has been accidentally put in washing machine iv dried it out but the screen has water behind the glass i don't know what to do replace the screen or buy new phone help

    my iphone 5 has been put in washing machine by accident and i have dried it out it works but there is water behind screen pleasehelp dont know what to do i can repair would it be best to buy new screen
    HELP!!!!

    It is likely that the device has unrepairable harm done to it having it washed in the washing machine. However, one thing that could be tried would be to have the device placed in a glad bag full of un-cooked rice and leave it there for 72 hours to see if this will absorb residual moisture showing up on the display glass. It could be assumed that if there is that much moisture showing it's unlikely attempting to draw out moisture will be sucessful.
    Good luck.

  • My computer has been freezing and then emitting a consistent beeping until I shut off the power. It has been getting really hot and the fan gets really loud. This has been going on for months. What's going on?

    I just had my macbook pro checked out and all of it's systems restarted to solve its beeping and freezing problem. However, it is still shutting itself down when I close the lid and becoming very hot.  When I open the lid again the screen is black and I have to continually hold down the power button in order to turn it back on. Does anyone know why this is happening?

  • Firefox repeatedly has no bookmarks, no history and will not let me add bookmarks. I have fixed this several times (deleting some sqlite file), but the problem recurs. It's enough to make me give up on firefox. Using iMac with OSX.

    This problem happens upon upgrades, but may have happened between upgrades as well (happened so much I've generally given up on using bookmarks or history with firefox).
    Thanks!

    When you don't have enough storage to perform an operation, then you don't have enough storage.  have you got the 16GB iphone?

  • YOUR APPLE COMPUTER HAS BEEN BLOCKED

    Recently, there is a Mac system alert says that "your apple computer has been blocked". It appears every times when i use websites. Indeed, some strange ads websites show up suddenly while i am using websites. What's more, the websites always break down since the alert appears. What can i do?

    You may have installed a variant of the "VSearch" ad-injection malware. Follow Apple Support's instructions to remove it.
    If you have trouble following those instructions, see below.
    Malware is always changing to get around the defenses against it. This procedure works as of now, as far as I know. It may not work in the future. Anyone finding this comment a few days or more after it was posted should look for a more recent discussion, or start a new one.
    The VSearch malware tries to hide itself by varying the names of the files it installs. To remove it, you must first identify the naming pattern.
    Triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination  command-C:
    /Library/LaunchDaemons
    In the Finder, select
              Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
    A folder named "LaunchDaemons" may open. Look inside it for two files with names of the form
              com.something.daemon.plist
    and
               com.something.helper.plist
    Here something is a variable string of characters, which can be different in each case. So far it has always been a string of letters without punctuation, such as "cloud," "dot," "highway," "submarine," or "trusteddownloads." Sometimes it's a meaningless string such as "e8dec5ae7fc75c28" rather than a word. Sometimes the string is "apple," and then you must be especially careful not to delete the wrong files, because many built-in OS X files have similar names.
    If you find these files, leave the LaunchDaemons folder open, and open the following folder in the same way:
    /Library/LaunchAgents
    In this folder, there may be a file named
              com.something.agent.plist
    where the string something is the same as before.
    If you feel confident that you've identified the above files, back up all data, then drag just those three files—nothing else—to the Trash. You may be prompted for your administrator login password. Close the Finder windows and restart the computer.
    Don't delete the "LaunchAgents" or "LaunchDaemons" folder or anything else inside either one.
    The malware is now permanently inactivated, as long as you never reinstall it. You can stop here if you like, or you can remove two remaining components for the sake of completeness.
    Open this folder:
    /Library/Application Support
    If it has a subfolder named just
               something
    where something is the same string you saw before, drag that subfolder to the Trash and close the window.
    Don't delete the "Application Support" folder or anything else inside it.
    Finally, in this folder:
    /System/Library/Frameworks
    there may an item named exactly
                v.framework
    It's actually a folder, though it has a different icon than usual. This item always has the above name; it doesn't vary. Drag it to the Trash and close the window.
    Don't delete the "Frameworks" folder or anything else inside it.
    If you didn't find the files or you're not sure about the identification, post what you found.
    If in doubt, or if you have no backups, change nothing at all.
    The trouble may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
    This trojan is often found on illegal websites that traffic in pirated content such as movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
    In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere  should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
    Then, still in System Preferences, open the App Store or Software Update pane and check the box marked
              Install system data files and security updates (OS X 10.10 or later)
    or
              Download updates automatically (OS X 10.9 or earlier)
    if it's not already checked.

  • My address bar has https with a lock on it.... don't know what I did? to put this on...need help

    I was changing things on my computer and I am not a real wiz at this stuff.  My safari when I open it now shows https with a lock on it.  I need help on removing this and also my google is missing from the address bar.  Anyone know what I have done?

    Safari 6
    URL address bar and Google search bar are combined into one bar now.
    Apple calls it Smart Search Field.
    There is no more a separate Google search bar.
    https with lock icon means that information entered in the bar is encrypted for the purpose of security.

    Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
    I suggest that you try to repair the phone software using PC Companion..
    Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
    How to backup?
    If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.
