MacBook pro won't start after update

Help my MacBook pro was doing an update when it went to restart it never came back on and seems to be stuck somewhere between sleep and on there is no lights but a faint white light on the case open button.

OK, I ran the latest update and my computer would not restart no matter what I tried. So I restored from a backup and everything was fine. Now I just did the OS update again and the SAME thing happened. Only this is a different hard drive.
There is definitely something screwy with this latest OS update and, at the very least, my model of Macbook Pro.
Apple is wrong.
I lost a week's worth of data in the crash.

    I updated my MacBook pro last night, I went to start it up this morning and all it does is sit at the spinning wheel start up screen. Any advice/help to fix this?

    Did you do the Lion update or are you still on 10.6.8 Snow Leopard?

  • Macbook Pro won't startup after Update

    I guess everyone has been having problems around here. But I really have no clue what to do. I did not even know there was un update until I restarted. After I did it now my macbook pro won't start up. It makes that chime noise at the beginning and then it shows the apple and the spinning thing below it and I left it for 2 hours and came back and nothing had changed.
    It my computer broken? Did I do something wrong? Have I lost all my stuff? Please help!

    Yeah, I have had the exact same problem. it happen last friday. Also, i'm not sure if this is related or not but right before the update the computer for no reason in the middle of doing stuff it would tell me to force shut down by holding down the power button. not sure what to do. If i ship it out it will be about a 2 weeks before i get it back and if I take it in, they can't put it on the bench for about 5 days. its very frustrating and apple needs to figure something out for service.

  • MacBook Pro won't start after changing RAM cards; just beeps.

    MacBook Pro will not start after changing RAM cards.  It just beeps; then I force it to quit.

    The three things that come to mind immediately are that the RAM card isn't seated properly (you should hear or feel a click when it is seated), the RAM is bad or marginal for that Mac model, or you didn't get the correct RAM type.

  • MacBook Pro won't start after I completed my first backup using TimeMachine

    Hello,
    My MacBook Pro won't restart after I did my first TimeMachine backup.  I tried in SafeMode but no luck.  My MacBook Pro is a 2009 early version running Snow Leopard.  Please help.
    Thanks,
    Serey

    I have managed to get into my computer through the OS X install disk but now my wi fi hardware is gone. Ie no airport.
    When I try to re install the airport extreme wi fi base station software  it tells me it can't be installed as this version of Mac OS X (Lion) on is volume is not supported.
    Not even an Ethernet cable gets me on line. In system preferences when I do a network diagnostic all I get is the spinning disk. Again, any ideas how to get around this?
    Thanks

  • MacBook Pro won't start after changing access rights

    I did something very wrong. Unfortunately I changed the access rights of Macintosh HD for "everyone" to none.
    Result, my MacBook Pro won't start anymore.
    Already tried the installation disk, reset password for root and users. No result.
    Help program "check acces rigths". Didn't work either.
    How do I reset the access rights of Macintosh HD?

  • Help - Macbook Pro won't start after running update

    I just checked the FAQs here and ran several searches and have not found an answer to my problem. I sure hope someone here can help.
    Today I installed the big batch of updates Apple released recently (I think it was on July 31) on my 2.4 GHz Macbook Pro. When I turned it on, I was told there was one last update that required me to turn off the machine and then hold down the power button.
    I did, and the machine started to come on, but I guess I held the button down a little too long. Now the machine won't turn on. Everytime I press the button, I hear the same sound I always get when I turn on my machine, except that now the sound just goes on and on and on, and the MBP never actually boots up.
    I wish I could remember the exact name of the update. I think it might be the EFI Firmware Update 1.2 that's described at http://www.apple.com/support/downloads/macbookproefifirmwareupdate12.html. That scares me because the words "Important: Do not interrupt the update" suggest things can go badly if the update doesn't go right the first time.
    Any advice as to what I should do?

    That sounds like an interrupted firmware update. And Macs with interrupted firmware updates are very unhappy Macs!
    You will need to restore your firmware to it's original state, then reapply the update. For this, you'll need to create a Firmware Restoration CD.
    See this page:
    http://docs.info.apple.com/article.html?artnum=303469
    Here's one of the more important sections of the page: +"If your computer is already in this state, you'll need to download the software and create the CD on another Macintosh computer, or you can take your computer to an Apple Store or Apple Authorized Service Provider to restore your firmware. This CD can be created on both PowerPC- and Intel-based Macintosh computers."+
    You might be better off just taking it in to an Apple Store.
    Ps. When you get a chance, you might want to update OS information in your forum settings - I'm pretty sure you're not running 10.3.8 Panther on your MBP!

  • Macbook Pro won't sleep after updating to 10.4.11

    Hi,
    I just updated to 10.4.11 reluctantly from 10.4.9 as whenever I do update I always have issues...I basically just went to software update last week and updated to everything I could. I've just been reading the forums and noted that updating is not always that easy...
    Well basically my computer won't sleep if the lid is left open, this is IMMENSELY annoying since I often leave my desk to work on drawings, and I don't want energy being wasted like it is at the minute. Call me picky but I just want my computer to work.
    I've reseted the PRAM, (option, alt, p and r), closed all applications, etc, but no luck...
    Its a 2.2ghz MacBook pro, 2GB. Thank you in advance
    Neal

    The important thing for the future imho, is to always Repair Permissions before & after any update... seems to ward off most of these problems. Of course that is only good if the disk is Verified once in awhile.
    Using Disk Utility in Mac OS X 10.4.3 or later to verify or repair disks...
    http://docs.info.apple.com/article.html?artnum=302672
    About Disk Utility's Repair Disk Permissions feature...
    http://docs.info.apple.com/article.html?artnum=25751
    In fact I'd start with those 2 now, if that doesn't help you may need to reapply some updates by getting them directly from apple>downloads.

  • Macbook Pro won't start after upgrade to 10.5.2

    I just updated my Macbook Pro 1.Generation to 10.5.2 via software update. After a double boot, the apple logo and the loading wheel appeard as expected. After several minutes of loading, i had to login. After login, the leopard wallpaper appears and then nothing happens. I cannot do anything. It seems that the finder and the dock won't start up.
    I have several apps installed, which may cause this issue. For example DockDoctor.
    What can i do? Do i have to reinstall leopard and try again to install 10.5.2 via CombiPackage?
    Thanks for help

    Start by:
    Repairing the Hard Drive and Permissions
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) 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 installer. Now shutdown the computer for a couple of minutes and then restart normally.
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Then download the standalone updater and reinstall 10.5.2. If that doesn't solve your problem then you will have to do an Archive and Install.
    How to Perform an Archive and Install
    1. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
    2. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
    3. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
    4. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
    5. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

  • MacBook Pro won't start after ML installation

    I installed OX S Mountain Lion and I then put the pro to sleep.  Went about the night and about two hours later I came back to check out new features and so forth and after clicking with the mouse, the pro won't do anything.  Basically the MacBook Pro is shut down and I can't start it back up.  Any ideas?  I have never had a problem with this pro until I installed ML.

    Thanks for the update. Some others seem to have a very similar problem:
    https://discussions.apple.com/thread/4147462?start=0&tstart=0
    https://discussions.apple.com/thread/4159707?tstart=120
    Based on this, I'm not convinced it really is hardware that's to blame, as in all cases it's been shortly or immediately after Mountain Lion was installed.
    I had some success last night. I left the machine unplugged completely all day, then last night plugged in and did the SMC reset procedure. Whether I was doing it incorrectly before, or leaving it unplugged all day made the difference, I'm not certain. However, it successfully booted!
    I immediately disabled the sleep function, and closed most applications and left it running overnight. Unlike last time when the Genius managed to get it to boot (after it was left unplugged all night, I might add), it's still running fine today. If it's still running by the time I get home I will try re-enabling the sleep to see whether it makes the difference.
    The logs from when it froze up previously show nothing out of the ordinary as far as I can tell. The last item in the console related to a memory usage report of the TuneUp app, and daily.out finished five minutes before it froze at 3.25 in the morning.
    I'm hoping I can narrow it down to something in the system and then just work around it until there's an update. It's obviously not widespread, but it has affected some people. I'll post back if I find something significant.

  • Macbook pro won't boot after update to 10.6.8

    Hi everyone,
    Yesterday I bought an used macbook pro (15 inch early 2008). When looking at it, it was in good shape and the previous owner just did a fresh install of snow leopard. I took it home and whas happy with it. In the first two hours of using it, everything was fine. After installing the update to 10.6.8 my macbook needed to be shut down.. After shutting down it started up again but the screen stayed black. I had no idea why. So I rebooted it by pressing the power button. The same problem remained, it seemed to start up (I could hear the harddrive and fan) but it didn't boot into Mac Os. After a couple of attempts, it now shutsdown immediatly after pressing the powerbutton (3 seconds after). No chime or nothing.
    At first I thought this would only be a software problem, because the problem started immediatly after updating. So I put in my snow leopard dvd to boot into that, but I can't even get it to boot into the install dvd. Because it shuts down immediatly after pressing the power button. Then I started suspecting an hardware failure, which would be a very big coincidence to show up immediatly after booting up. These are the things I have tried so far, to no avail:
    - Plugging of the power cord and removing the battery, then pressing and holding the powerbutton for at least 5 sec
    - Holding the option, command, P and R keys during boot.
    - Replacing the memory
    - Replacing the hard drive
    - Unplugging the super drive
    - Starting up holding the d key
    At a certain point I was hoping that It would be an harddrive or memory problem. I replaced both with examples I know for sure they are working. But still the same problem; macbook shuts down  almostimmedialty after pressing the power button.
    There is no warrany anymore, and technical support would cost me 49 euros per incident.. to probably hear that the macbook is beyond repair. I feel i have just thrown away 300 euro's for an nightmare experience. Does anybody now anything to try, i'm really desperate here

    After installing the update to 10.6.8
    What update was that?
    So I put in my snow leopard dvd to boot into that, but I can't even get it to boot into the install dvd.
    Did the previous owner also give you the discs that originally came with the computer?  Those are what you need to troubleshoot with.  You also need disc 1 to run the Apple Hardware Test.
    There is no warrany anymore, and technical support would cost me 49 euros per incident..
    Apple Store and AASP diagnostic testings are free.  Suggest that you take full advantage of it.  This way you can find out exactly what is wrong with your computer.  Post back here with the diagnosis and someone will post DIY repair sites.

  • Macbook Pro won't start after Mountain Lion download.

    Downloaded Mountain Lion for my 2007-08 Macbook Pro. Internet was painfully slow (60kb/sec, usually 15 mgb/sec). After not using it a week while vacationing, I started it up, and it was working fine until it randomly shut down and brought up an error screen (hence the reason it shut down) and asked if I wanted to boot normally. I powered it down; now it won't start at all. Power button doesn't work, demounting the battery for a minute and remounting doesn't work, nothing works. I have a genius bar appointment soon, but am wondering if anyone has some advice.

    Close problem - I believe the problem is RAM is storing your last data, and not releasing it, so you cannot boot it. Trying removing RAM fully, then starting.

  • 2009 Macbook pro won't start after 10.6.3 upgrade

    Updated my macbook pro this morning when I received the software update notice, received an error message that the process encountered an error, upon restart the macbook pro hangs on the grey screen with the apple in the middle, then turns off. Won't restart in safe mode, but will restart in single user mode (not that I know what to do there). I also started from the snow leopard disk and went to disk utility, tried to repair permissions, but received an error message there as well. I even tried re-installing snow leopard from the disk but received the message " installation of the contents of this disk can't be changed". Help!!!!

    Loaded up the snow leopard disk, used disk utility to erase and reformat the HD, re-installed SL, then installed the combo update, all is fine again. Worst upgrade experience I have ever had to deal with....
