Late-2009 Macbook Pro 10.9.2 Random Shut Down

My Macbook has started intermittently shutting down while in use anywhere from 10 min. to 4hrs  after startup. I took it to the Genius bar where they advised me to unistall Chrome and remove several Launch Daemons. After removing those, my computer ran well for 3 days after which it began shutting down again. Today it began to shut down (screen off, indicator light off), resist restart (would not power back on for over 15 mins), and then switch back on without going through the normal startup procedures. AHT said that everything was in working order and I have already reset the SMC. Currently I can't keep my computer on for more than a couple minutes at a time so I will post my kernel panic log ASAP.

  • Went from Mountain Lion to Yosemite on 2009 MacBook Pro.  Safari now randomly shuts down; Word doesn't work properly; iPhoto will not upload pics from iPhone; EVERYTHING is horribly slow.  How to I go back to Mountain Lion?

    Is there a way to go back to Mountain Lion after updating to Yosemite?  Yosemite has caused nothing but problems in multiple programs.  Mountain Lion ran fine.  Not sure why I even updated.  I am NOT a computer guru so instructions I have read for the many Yosemite fixes blow my mind.  Should I be taking my MacBook Pro to the Genius Bar at the nearest Apple Store (2 hours away)?  I have been a Mac user and lover for many years and am SO frustrated and disappointed in all of it right now.  Please advise on what a non-tech frustrated Mac user can do.

    Technically, you can downgrade if you have the following:
    Your computer must be elligible to run Mountain Lion. If your computer came with Mavericks or Yosemite out of the box, you can forget it.
    You need an already existing Mountain Lion installer file. If you still have that somewhere, for example in your Applications folder, or anywhere else, it's usable- note that it needs to be originally downloaded with your own Apple ID and password. If you made a Mountain Lion USB installer or DVD back then that would work too. If your Time Machine back-ups go back to the days of Mountain Lion or Lion you could check your Applications folder from inside Time Machine and restore it to your computer.
    To not have data loss you need a Time Machine back-up that goes back to when you were still running Mountain Lion. Please note that this will revert your data to exactly the date that you choose. If you installed Mavericks 2 months ago, you will loose 2 months worth of data.

  • My Macbook Pro (early 2011, 15") randomly shuts down after being turned on from sleep mode?

    -So over the past week, I find that my macbook pro will randomly shut down within 1 minute of being turned on from sleep mode. Within the first few days of this, I figured out that it will only happen if I move my mac around before its completely into sleep mode. BUT now it shuts down regardless or preparation before sleep mode and everytime I turn my computer back on, I log in, and then have restore my chrome window tabs and stuff. What is going on??
    -Do I need to replace my drive??
    *PLEASE help me, thanks!
    P.S. - I am runnng OS X Mountain Lion 10.8.5

    austine38,
    if you boot into Safe mode, and then immediately restart into normal mode, log in, and put it to sleep, does it still exhibit the same random shutdowns afterwards?

  • I own a late 2009 Macbook Pro, and it keeps freezing after OSX Lion installation.

    I own a late 2009 Macbook Pro, and it keeps freezing after OSX Lion installation.  I will post my computer's 'specs' below.  I installed Lion, from Snow Leopard, through the App store.  The first week, it worked like a dream, and was loving my brand new computer, or so it seemed.  I then began to run into problems, and I can't confirm this 100%, but I believe it was after I updated from 10.7.1, to 10.7.2. 
    The freezes are sporatic at best, and cannot be narrowed down to one app.  I googled the issue about two weeks ago, and found a fix involving a temporary log-in, verifying the disk, restarting the computer holding CMD+R, and repairing the disk from there.  That fixed the problem.  For about three or four days.  From there I brought my laptop to Best Buy, where I purchased the computer (start the groans, my dad wanted the accidental damage, and he was paying, there was no argument).  My warranty there was still good, but all they were offering was to check my hard-drive, and possibly ship it out.  That would not be good for me, as I am a High School student, who works online. 
    So I then decided to go to the Apple store, see what they said.  They said a bunch of people had this problem, it would cost a lot to fix, as I would need a new Logic Board.  This did not make any sense to me, as I knew it was Lion's fault, so why would they not make the L-2009MBP Logic Board compatible, and why are only a few people having this problem, well a lot more than a few, but I mean not everyone. 
    So I asked a friend about it, and we decided to run a back up, and erase the computer, and re-install Lion.  Figuring maybe my data was corrupted during install.  This helped for a day or two, and happened again.  So this time, we backed up only files (music, pics, documents, etc.,) and did a fresh install.  I got my computer back last night.  Now, I am not saying that didn't help.  Previously I would have frozen about 18 times well writing this, but I have not frozen once (hopefully I didn't just jinx myself).  I have gone from about one freeze every 10-15 minutes (sometimes worse), to about one every 1-3 hours.  Which, let's be honest is still a lot. 
    So, before I just decide to go and revert to Snow Leopard on my merry way, I ask, do any of you have any other ideas?  Or guarenteed fixes?  I know a guarentee is a hard thing to ask for, but I am desperate, my teachers are getting angry with me for not sending work, and I know this would help a lot of people.  Thank you to those who read through my whole spiel, and thank you to those who will help me!
    [Ps, while I am somewhat of a noob, I know my way around a computer, so any help, or knowledge you could bestow upon me is awesome.  Especially DIY fixes.  (if your only advice is, don't buy a mac at Best Buy, don't bother commenting)]
    Macbook Pro

    Graphics:  NVIDIA GeForce 9400M 256 MB

    Once it is downloaded you need to restart the computer if it does not restart automatically. When it next starts up you should note a progress bar appearing below the Apple logo. When done the computer will restart once more. The new firmware should now be installed.

  • My MacBook Pro Core Duo from 2006 shuts down randomly requiring frequent reboots to the point I had to abandon doing any project or anything on this MacBook Pro. Same thing occurs with the iMac dual core from 2007. MacBook battery replaced.

    My MacBook Pro Core Duo from 2006 shuts down randomly requiring frequent reboots to the point I had to abandon doing any project or anything on this MacBook Pro. Same thing occurs with the iMac dual core from 2007. MacBook battery replaced. Is it internal battery for both, new logic board required, bad hard drive, or bad RAM?
    Help.

    Run an Apple Hardware Test using the original installation disk that has the AHT instructions on it.
    Try SMC and PRAM resets:
    http://support.apple.com/kb/ht3964
    http://support.apple.com/kb/ht1379
    It is possible that you may need a new PRAM battery.

  • MacBook Pro sometimes stays on after shut-down and drains the battery.

    Sometimes my MacBook Pro stays on after I shut it down and it drains the battery until it dies. I return home to find it the clocks and everything have to be reset.  It appears to be shut-down after I select that command, but on occasion it will remain on in a semi-on state and i need to force quit it w/ the power button.  It usually shuts down ok, but this happens every once in a while and I have to continually double-check that it's off before leaving it.  Otherwise, I will come back and the battery will be very warm and the machine is running, but not really on.  Any ideas?

    Problem solved by my own. But do not how :) magsafe again working and the laptop tooo

  • Late 2009 Macbook Pro reading selective discs

    Hi there,
    I own a late 2009 Unibody Macbook Pro. Running snow leopard.
    I've been having issues with my disc drive for the longest time now but now it's just becoming irritating and am looking for a solution or I may need to get my MBP combodrive serviced.
    I'll place a DVD movie into the combodrive, it spins, spins real fast then stops and sits idle, Spins again for a few seconds and sits idle. RInse and Repeat for about 5 minutes.
    Then I get a popup message stating that I inserted a blank DVD, which is clearly not the case.
    Now this is the fourth disc out of the boxed set the first 3 discs worked fine. Now its just this one that is having the issues.
    I've tried cleaning the lens, SMB reset, everything.
    Anything else anyone can suggest?

  • Late 2009 Macbook Pro won't turn on

    Last Friday, my half charged Macbook Pro randomly turned off and was unresponsive.  No sleep/power indicator light, no start up chime, nothing.  The only thing that works is the battery indicator light. I have tried a PRAM reset, SMC reset, everything suggested on this website and in the manual. I'm wondering what I'm looking at replacing here, and what the cost could be.

    I think a visit to an Apple Store or a Service Provider may be the best choice, if only for the diagnosis. There's a high probability that repairs will be costly so you'll want to make sure to hit the problem dead on instead of splurging money all over.

  • 256SDD or 1TB HD on late 2009 macbook pro?

    Hello,
    my mac had to be repaired due to water damage and it turns out that the hd is not functioning anymore. The repair company (RC) has given me some options for replacing the hd but I am not much of a techie so I would really appreciate some help.
    My mac has the following specs Macbook Pro 15 inch, 2.53GHz mid 2009. Ram is 4GB. The RC offered to replace the hd and place a 1TB hd. They also advised me to upgrade Ram to 8GB. Alternatively they offered to place a 256GB SSD.
    I use my mac for very light stuff, surfing the web mostly, some Word and Pp. I do download quite a bit. I used to game as well (WoW) but haven't in years. Can't say I never will again though. I don't have the money to buy a new Macbook as of yet, and I was happy with how my Mac performed before it died. Could be a bit faster maybe but overall, it was fine for me.
    Would love to hear your advice,
    Eva

    It will cost more than the HD. The HD is €250 and the SSD is €330. That's an all-in price. I don't really back up my Macbook, other than that my important files are automatically saved in a Dropbox folder. So everything has to be on the Mac, I don't want to carry around an external harddrive in case I opt for the SSD.
    Is an SSD really that much faster than a regular HD? I have been reading up on them and get a lot of info on users that rely heavily on their macs for Photoshop and the like. But I don't use my Mac for that and I rarely shut it down. Would an SSD then still provide me with signifant benefits to justify the extra cost?

  • Can I exchange my late 2009 macbook pro for the new 2010 one?

    Ya, just what the subject asks... I really like to keep up with technology, and I bought my macbook pro like 1-1/2 to 2 months ago...

    There aren't really any quad-core options that have reasonable power requirements at this time. The current machines that do use the mobile i7 quad core processors are all pretty hefty desktop replacement machines and typically get just a few hours of runtime on battery.
    One of the advantages of the i5 and i7 (dual core) over the previous Core 2 processors is that they use Hyperthreading. So, the OS actually "sees" 4 cores and each of those four cores can be utilized as if it were an actual core.

  • Macbook Pro running very slowly, randomly shutting off and overheating. No idea what the problem is! Please help!

    I got macbook pro about a year and a half ago and up until now it has been running fine.
    However, in the last few days, it has been started to run tediously slowly!
    It wont allow me to open applications and i have to force quit out of any applications I finally manage to have because they freeze or stop responding.
    On Google Chrome, pages become unresponsive every few minutes.
    Even writing this post took more than 20 minutes as the laptop kept freezing and the webpage became unresponsive.
    It also randomly shuts off and when it restarts, a message comes up saying my Macbook was restarted because of an error.
    I haven't downloaded or updated anything that I know of recently that would have caused this.
    Ive been reading through some of the fourms on this and I thought it'd be helpfull to post some of the information you may need to help me solve this problem!
    Id be very gratefull if any of you could help! Thanks!

Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load 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, or if a firmware password is set, or if the startup volume is a Fusion Drive or 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 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, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • MacBook Pro goes grey screen, then shuts down randomly

    My MacBook Pro (just purchased 3 months ago, not retina) shuts down unexpectedly. The screen goes grey, then it just shuts down after a few minutes. Anyone else have this problem? Any ideas how to fix?

    You need to reset the SMC on your Macbook.
    * Shutdown your MacBook Pro
    * Connect the power adapter to your Mac
    * On the MacBook's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
    * Release all keys and the power button at the same time
    * Boot your Mac as usual

  • MacBook Pro (10.7.3) not shutting down after updating to latest iTunes

    This is a bit of a strange one, and after searching high and low, I haven't seen any other references to it, so...here goes:
    I'm working on a MacBook Pro (13-inch, Mid 2010) running OS X 10.7.3, and the complaint is this: the system will not shut down or eject a connected iPod (classic) or smartphone (Verizon Android phone) after updating to the latest version of iTunes.
    I've been troubleshooting this for several days now, and I've tried the following:
    1. Created a new admin account and tested from there. No change.
    2. Created a backup image of the hard drive, erased & reinstalled 10.7, created temp admin account - issue resolved, but iTunes library unable to open because it was modified by a newer version of iTunes.
    3. Ran software update to bring system current (as of 20 April 2012)
    4. Issue reappears after software update.
    5. Reinstalled 10.7.3 from Recovery partition.
    6. Again, issue resolved, but unable to open iTunes library modified by newer version.
    7. Update iTunes, issue returns.
    I actually did several variations of the erase & install routine, as well as several admin accounts, but the basic gyst of it is that after updating iTunes, the system hangs at the spinning gear on shutdown every single time.
    The version of iTunes that is reinstalled with Lion is 10.5.1. I don't know which version between that and 10.6.1 is causing the problem.
    Not sure where to go from here, so I figured I'd throw it out to the community.
    Thanks.

    Well, after throwing my hands up in the air, I returned the MacBook Pro and iPod classic to their owner because I'd held onto them for over a week trying to troubleshoot the issue with no success.
    Two days later, she contacted me and told me her iPod was the culprit -- it had some bad sectors on the hard drive. I had thought to check that, but she had data on the iPod that wasn't backed up anywhere, so I back-burnered that until later.
    Glad to see I'm not going insane, though. ;^)
