My MacBook Pro will suddenly quit while I'm working on it and restarts itself.

I have a 2012 MacBook Pro running OSX 10.8.2 Mountain Lion with a 27-inch Apple Cinema Display connected to it that I use at work. I am an art director so I am constantly in Adobe Creative Suite 6. In the past month my MacBook Pro has suddenly quit on me while working and restarts itself TWICE. This time I was listening to a downloaded album on iTunes and the music started to skip right before the computer crashed and restarted itself. Has anyone ever experienced this before? It doesn't freeze up or anything like that, it will just unexpectedly go into Restart mode & the computer restarts. Everything is fine once it restarts but I am wondering if I should be concerned or if someone might know of a repair solution I could do on the computer. Should I run Disk Utilites to see if their is an issue? Would appreciate any comments and suggestions and feel free to ask may any question. THANKS!!

Triple-click anywhere in the line below to select it:
syslog -k Sender kernel -k Message CSeq "Previous Shutdown" | tail | open -f -a TextEdit
Copy the selected text to the Clipboard (command-C).
Launch the Terminal 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 Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Post the contents of that window, if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that.

  • My Macbook Pro will not charge. I have tried other charges and nothing. Can the MagSafe port go bad? Is that expensive to repair?

    My Macbook Pro will not charge. I have tried other charges and nothing. Can the MagSafe port go bad? Is that expensive to repair?

    The port can fail. Internal boards can fail. Batteries can fail. All with the result that no charging occurs. 
    You can try Resetting the System Management Controller and you can try Troubleshooting MagSafe adapters. 
    But usually you will have to take the mac in to a service place for testing.  It can get expensive, although occasionally it is not.

    I have read that new purchases of macbook pro will get free upgrade to LION OS. When and how do I go about this?

    http://www.apple.com/pr/library/2011/06/06lion.html
    The Mac OS X Lion Up-To-Date upgrade is available at no additional charge via the Mac App Store to all customers who purchased a qualifying new Mac system from Apple or an Apple Authorized Reseller on or after June 6, 2011. Users must request their Up-To-Date upgrade within 30 days of purchase of their Mac computer.

    I have the same camera and never had a problem connecting it to my PC. I just bought a MacBook Pro and now I cannot figure out how to get it to recognize the camera either. Sorry I cannot offer any suggestions, but wanted to get on this thread to see if anyone else can help. Good luck!

  • My macbook pro will not sleep while connected to a Thunderbolt Display.

    I am getting frustated on this issue after receving little assistance from apple support.  I can put the macbook pro to sleep and all indications are that is sleeping.  It;s hard to tell with a macbookpro retina because they don;t have the pulsiong light to show when in sleep mode like the non-retina models.  I can put the laptop in sleep mode and then return 8 hours later to find the laptop is warm to the touch and doesn't appera to have slept during this time.  I can follow exactly the same steps when "not" connected to the thunderbolt display and the macbook pro is cool to the touch and appears to have slept nicely. what is going on here?  I am using a bluetooth keyboard and trackpad and the issue is replicated when in clamshell mode and when the lid is open.

    I'm seeing similar behavior when I disconnect my TBD. My Retina MBP doesn't go to sleep. I get to work an hour later and it is very hot to the touch.
    I'm not seeing lots of people complaining, so I wonder if it's something weird I do. Do you have VMWare Fusion or XQuartz running when you try and sleep?

  • After updating to 10.10.3, now my Macbook Pro will not stay logged in. I log in after restarting, and it will stay logged in for 3-5 seconds then immediately log off and go back to the login screen. Any help?

    After updating to 10.10.3, now my Macbook Pro 15" (mid-2014) will not stay logged in. I log in after restarting, and it will stay logged in for 3-5 seconds then immediately log off and go back to the login screen. Any help?
    By the way, I also updated my Macbook Pro 17" (mid-2009) and it seems to be running fine, though I haven't tried to restart it and log in. I'm afraid I won't be able to get this one to work either if I do.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

    If you're sure you've installed the latest version of Flash, take each of the following steps that you haven't already tried. After each step, relaunch Safari and test. For a "missing plug-in" error, start with Step 5.
    1. If you're only having trouble with YouTube videos, sign in to your YouTube account and load this page. You may see a link with the text "Leave the HTML5 Trial." If so, click that link.
    2. If you're getting a "blocked plug-in" error, then from the menu bar select
     ▹ System Preferences… ▹ Flash Player ▹ Advanced
    and click Check Now. Quit and relaunch your browser.
    3. Triple-click anywhere in the line below on this page to select it:
    /Library/Internet Plug-Ins
    Right-click or control-click the highlighted text and select
    Services ▹ Open
    from the contextual menu.* A folder should open. Delete the following item, or anything with a similar name, if present:
              •          Flash Player (failing).plugin 
    You may be prompted for your login password.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combinationcommand-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
    4. Re-download and reinstall Flash. Download it from this page:
    Adobe - Install Adobe Flash Player
    Never download a Flash update from anywhere else.
    5. If you get a "missing plug-in" error, select
    Safari ▹ Preferences... ▹ Security
    from the Safari menu bar and check the box marked Enable plug-ins.
    6. Select
    Safari ▹ Preferences... ▹ Extensions
    from the Safari menu bar. If any extensions are installed, disable them.
    7. In the Safari preference window, select
    Privacy ▹ Remove All Website Data
    Close the window. Then select
     ▹ System Preferences… ▹ Flash Player ▹ Advanced
    and click Delete All. Close the preference pane.
    Hope thi helps

  • Macbook pro will not turn to almost have changed the motherboard and the power supply board

    Hello,
    A customer brought me to repair his macbook pro A1151, the computer flashed, I had to change the power board and the motherboard and the computer still does not turn.
    The customer used a power supply with wire was déterrioré there were overheating the power supply board has traces of burns and a component of the motherboard is broken.
    What may be another problem that prevents your computer from turning on?
    Thank you.

    Run an Apple Hardware Test:
    http://support.apple.com/kb/ht1509
    It may pick up some information that might give you a clue as to the unusual behavior.
    Note: An error free AHT is not always definitive.
    I still would go to an Apple store genius bar and have the MBP examined.  It will be done for FREE regardless of warranty status.
    Ciao.

  • New MacBook Pro Will Not Charge While in Use

    I'm not sure if this is an issue, however, I have been unable to find more information regarding this, so I thought I'd ask. While plugged in (MagSafe LED=Orange) the computer hovers around the same percentage of charge (i.e. +/-2%), even with very low to no use, and every once in a while says (Not Charging). However, when in sleep with the deck shut, it charges promptly as it should.
    I've occasionally seen it charge slightly while in use while using the plug without the extension portion, however I am unsure if this is related. I have tried resetting the SMC, restart, etc. So my question simply is, is this an issue, or is the computer specified not to charge while open?
    Thanks!

    As eww indicated, it may be a fault with the charger. The reason for my question was because you can use the 60 watt charger that comes with the 13" model on the 15" model (which comes with an 85 watt charger), but... it will only provide enough power to operate the 15" model while in use... it does not provide enough power to both operate the machine while charging it. It will only charge with the machine shut down. Your symptoms sounded very similar... but as you're using the correct charge, it may just be a bum charger. These types of things tend to fail early on if they're going to fail at all. With it only being a few weeks old, that would also seem to make it more likely to be a faulty charger. Apple tends to be very good with these things. If you have an Apple store nearby, set up a Genius appointment online. There's a good chance they'll just replace the charger for you. It's a good to bring it in though so they can check it out for you just in case the problem is with the charging circuitry in your Mac and not the charger.
