Help - I just installed Mountain Lion and now my MacBook Pro crashes all the time

Hi everyone. I've recently installed Mountain Lion on my MacBook Pro and now it randomly crashes. I tried finding the pattern (maybe when I open a specific app, or go through a series of steps) but nothing, it just happens, and it feels random.
Here's the latest panic report I got:

Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:

Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. They should be more than willing to install a new logic board at no cost. I have no idea why this faulty GPU is making the headline here on the MacBook Pro forum so often now - could it be because Mountain Lion is just bringing the issue to a head more readily? I don't know - I only know that we're seeing more and more of these kernel panics of late.
Good luck,
Clinton

  • I was installing mountain lion and now my macbook pro won't start up

    I was installing Mountain Lion and i restarted my computer and now it won't boot up.

    Reinstalling Lion/Mountain Lion Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

  • While trying to instal Mountain Lion OS on my macbook pro, I got the error message that my HD was damaged and it reverted to my Lion OS. Why does this happen? I bought the OS online through the app store

    While trying to instal Mountain Lion OS on my macbook pro, I got the error message that my HD was damaged and it reverted to my Lion OS. Why does this happen? I bought the OS online through the app store.

    The Mountain Lion installer looks at your internal drive to make certain that it's error-free before continuing installation. You should have an application named "Install OS X Mountain Lion.app" in your Applications folder now so you shouldn't have to download it again. Do this...
    Boot to your Lion recovery partition by holding down both the Command and the R keys while booting. Open Disk Utility from the Recovery partition and select your hard drive (usually named "Macintosh HD" unless you've renamed it) and click on Verify Disk. If you come up with any errors, click on Repair Disk. At the end of the cycle you will get a message that the disk was successfully repaired or a message that the hard drive could not be repaired.
    If you're able to repair the disk, just reboot as normal and open the "Install OS X Mountain Lion.app" and the installation will proceed. If Disk Utility was unable to repair the disk, you need to get to your local Apple Store as soon as possible so that they can see if the disk is salvageable or beyond repair.
    Good luck,

    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.
    1. If you're getting a "blocked plug-in" error, triple-click the line below 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. If there is more than one item in the folder with the words "Flash Player" (not "flashplayer") in the name, open the respective Info windows, check the version numbers, and delete all except the latest. You may be prompted for your login password. If you get the same error after doing that, re-download and reinstall Flash. Download it from this page:
    Adobe - Install Adobe Flash Player
    Never download a Flash update from anywhere else.
    2. 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.
    3. Select
    Safari ▹ Preferences... ▹ Extensions

  • Just installed Mountain Lion Latest Version on MacBook Pro Mid 2010

    I want to make sure, that after i spend so much money on a high end mac book pro in December of 2010, that now i can't even use the feature of apple tv mirror because my lap top has to be early 2011 or later. Please confirm Apple Gurus so that i can be sure that im didn't do anything wrong. I have the latest Apple Tv but my MacBook Pro 17 was purchased in dec. 2010. which makes it a macbook pro mid 2010. If the case is i can't utilize the mirror for my desktop to show in apple tv, then why does it work with itunes and every other device? so weird, plus i need to make sure i've done all the troubleshooting possible so then i go ahead to the next step and buy the USB to HDMI Cable that way i can do it the old way since my mac book pro high end is now considered old. So dissapointed.

    Look at this link.  It indicates that a third party application will allow you to use it:

  • MacBook Pro crashes all the time since installing Yosemite

    My MacBook pro has become almost unusable since I installed Yosemite.  I have a mid-2010 model MacBook Pro.  It spontaneously shuts off and reboots itself very frequently-- so frequently I can't get anything done.  It doesn't seem to matter what I am doing or which applications I am running.  I ran TechTool Pro and it repaired some files and permissions.   However, it's still spontaneously shutting off and rebooting just like before.   I'm starting to wonder if my machine is on its way out.  Can anyone help?

    Thank you for responding!   I ran Etrecheck and here's the report:
    Problem description:
    MacBook Pro (mid-2010 version) spontaneously shuts down and reboots very frequently since installing Yosemite.

    I installed Mountain Lion and now Illustrator CS6 won't open. I get a -1712 message. Help?

    Moving this discussion to the Illustrator forum.  What have you tried so far to resolve your difficulties?  Have you tried removing and reinstalling Illustrator?  If so did you receive an error message during the install process? 

  • I have just installed Mountain Lion and received a message that "speech Synthesis Server.app could not be opened because it is damaged or incomplete", please advise me what to do now.

    I have just installed Mountain Lion and received a message "speech synthesis server.app could not be opened because it is damaged or incomplete", please can you advise me what to do next? Thanks

    Something went wrong with your upgrade.
    Back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.

  • I just downloaded mountain lion and now my google chrome and spotify wont open

    I just downloaded mountain lion and now my google chrome and spotify wont open.  Any help would be appreciated.

    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, or by corruption of certain system caches. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and  Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in 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, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • I've just installed mountain lion and my files are all out of their previous folders. Can I set them back or do I need to manually put them back in order??

    Hi Thomas,
    Thanks for the response.  So, after the computer did it's restart thing after installing I went into finder where I usually have everything come up including my Macintosh HD folder and all it's folders and files.. Anyway it was this that hadn't come up and all the files were listed under All My Files and out of all their folders.  I totally switched the computer off after posted the problem and now having switched it back on I see that it's all there and in it's proper files.
