  • I have a MacBook Pro 2008 with 17 inch screen. Experiencing a lock up when turning on power to boot up. While booting up it goes to gray screen with Apple logo and disc spinning icon running and doesn't go to my desktop. Any solutions to the problem?

    I have an early 2009 17 inch MacBook Pro that just went on the fritz. When turning on the power it will go into boot up mode to the gray screen with the apple logo, then the disc icon will be running and will continue running, not allowing to proceed to my desk top screen. It's pretty much locked up at this point where I have to do a forced shut down by holding down the power button. I've tried everything that I know of such as taking battery out and pressing power button for 5 seconds and then reinstalling battery. I've cleaned inside of computer with compressed air duster in can as well as other key commands for resets. I've read that this is a common problem with the earlier MacBook Pros. Is this a problem that I can fix or does it have to be taken in for service? Any solutions to the problem would be greatly appreciated. Thanks!

    This could be a software/state problem or a hardware problem.  Here are steps to resolve the former.

    Sorry to hear of your problem, but any hardware in a computer can fail - that includes the hard drive, the logic board, etc, etc. Fortunately, it usually doesn't happen that soon; however, I've read of hard drives failing within 6 months.
    So, since you did not purchase the extended Applecare Protection Plan (3 years coverage), you will need to make a decision to repair or sell it as is. I would always purchase 3 year coverage for an all in one or a laptop because repairs are expensive and at least I'd be covered for 3 years.
    We can't speculate on whether there should be a recall or not; these forums are for user to user assistance with technical problems. In your case, there is nothing we can help with since you've already gotten a diagnosis.

  • Grey screen and "incorrect number of thread records"

    I think I am in trouble. My eMac will not boot and gets stuck on the great screen with the Apple logo and the spinning windmill. I have followed the instructions in the Apple help article up to but not including "archive and install". I tried the advanced secure boot and the messages I got over and over were "HFSSWAPHFSPlusBTIternalmode: catalog record #30 keylength=34 expected=144 node=15278 File ID=4 volume= Macintosh HD device=/dev/disk 0s 10"

    Snow Leopard is a Mac OS X version. You say that it's the version you have in your Mac (10.6.8). Do a back up of your files, format the hard drive (using Disk Utility) and reinstall again

    The internal drive is malfunctioning. What backups do you have?

    Reinstall OS X:
    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard 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 Utilities menu. 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.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro 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.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

    The qualifying product is the older version that you owned before you purchased the upgrade to version.  It is what qualifies you to use the less expensive upgrade version.  So you need to select the older version and provide its serial number to prove that you qualify for using the upgrade.

    On my mac I have both Quicktime X and Quicktime 7 pro. Both applications seem to be crashing quite often lately. This happens when playing all files types. I notice it more with .flv file. It usually happens when i grab the time slider bar and try to move it. The apps will freeze and I have to "force quit" to get them to close. Sometimes putting the computer to sleep and waking it up helps. Is there a way to remedy this?

  • My macbook 13' (older version) starts only to white screen with apple logo tried to rebooot by pressing shift at the opening but it didn't finish starting before stopping please help anybody please

    is anbody there how does this work never done it before my macbook won't start past white screen with apple logo any ideas ?

    Are you using a 10.6 Snow Leopard Install DVD? If yes, you can erase and install following these directions: http://support.apple.com/kb/HT3910
    You'll know whether or not it is a hard drive issue when you get to step 8 under "Part One: Erasing the hard drive". If you do not see your hard drive in the list on the left side of the Disk Utility window then you know the Mac isn't seeing it—could be a loose cable, but more likely hard drive failure.
    If you can see it on the left, click on it and look at the bottom of the Disk Utility window. If you see something like "S.M.A.R.T status: failing" that is definitely a hard drive issue. Otherwise, you can just follow the directions for an erase and install!
    Might be worth fixing depending how much a repair would cost. Genius Bar could at least diagnose it for you and give a repair estimate. I'd look at what a new or refurbished one with your same specs would cost though to see if the price differential is worth it...

  • My Mavericks Partition Will Not Boot due to "Incorrect Number of Thread Records", But Windows 7 On Same Drive Does

    I got up from my chair at the office to make myself coffee and came back to find my computer powered down. "That's weird," I said,  "I don't remember turning the computer off." I pressed the power button and the loading bar appeared below he apple symbol (as it should do on a bad shutdown) but alas, when the bar got to the end, there was a loading ring, and the computer immediately shut down.
    I then held down the alt key and was able to boot up in my Bootcamp Windows 7 partition (on the same hard drive) but I am unable to do a few things with my OS X Mavericks partition
    First off I have the entire partition backed up, as I was able to access all of the files and the drive using my windows partition (drive appeared in "my computer" I was able to copy paste everything just fine). Secondly when I boot in the Recovery HD, the "Macintosh HD" partition appears unmounted, I can't erase it because disk utility says that the disk could not be opened. When I try to verify it, it says that the drive needs to be repaired, but when I repair it, disk utility tells me "Error: Disk utility can't repair this disk...disk, and restore your backed-up files."
    tldr; I cannot erase the disk, I cannot repair the disk using disk utility in the Recovery HD, but I can see the disk in windows running on the same drive... so at least I have that going for me.
    I tried starting up in verbose mode and it failed after 3 tries, I attempted to use the method described here http://african-heart.blogspot.com/2010/07/fixing-invalid-node-structure-in-mac.h tml?m=1 . I have run the method 6 times and nothing has worked. Ideally I'd like to wipe the "Macintosh HD" partition and start again, but I cannot seem to do that through disk utility
    are there any methods for fixing the partition/wiping the partition that I am missing?

    The same thing is happening to me. I had just click on a form submit button and suddenly the video went dizzy for an very little instant, almost couldn't see it, the screen went black and a message warning the system crash appeared. After that, the system rebooted with a progress bar under the spinning circle and it turns my Mac off when it is fulfilled.
    Trying the native Apple hardware test right now to see if it can identify any problem.
    I'll post any news here in at most one hour, after the test finishes.

  • How do i get my limited internal storage of my macBook Air to use iCloud for photos library now on external drive -- I want to take my photos with me on my macBook Air?

    My primary computer is a macBook Air (late 2011). I have two external hard drive attached when I have it on my desk at home. I want to take it with me sometimes and not have to also lug a 3 TB external drive also. How do I get it set up similar to my music library with iTunes Match. The library is on the internal drive, but the media itself is on the external drive.
    How do I get the same kind of result as seeing my library on my iOS devices?

    I have already turned on iCloud Photo Library and it works just fine for my iPhone. BUT, what I want is for it work on my main machine, the macBook Air. I do NOT have an iMac or other to store the "system" Photos library. I do Not have room on my internal drive for the macBook Air ("system" library is located on an external drive). I don't want to have to lug that 3 TB drive with me. It also will not let me move the library file. The library file is close to 40 Gbytes and I have less than 20 left on my internal drive (and I don't dare let it get much smaller than this)....
    Any ideas as to how to do this?
    For my iTunes library, I ran into a similar issue, but I simply started a new library and dragged the files (on my external drive) into iTunes. This told iTunes where they were without copying them to the internal drive.
    I would think something similar should work with Photos, but I don't know how to do it.

  • When i open my computer I get the white screen with apple symbol and there are vertical lines all over the screen with green pixels and after a few minutes the screen gets grey and I get message to restart my computer what happens

    3 years ago I bought an IMac Desktop that I am using for a lot of things but the most important for dvd montage in Imovies and Idvd.
    Now today when I opened my computer I get as usual the white screen with the Apple symbol but there were all over the screen vertical lines with green pixels and after a while the screen gets grey and I get message to restart my computer using the power button or the restart button and when I do so each time the same is happening somebody can tell me what is happening and what caused this. This computer is my work and now I have no income anymore.
    On the Apple support site they are asking to enter the serial number and when I do so I get message it is wrong but it is the only one I have and I buy this computer in Cairo Egypt. I am living in Hurghada in Egypt for the moment. When I call the technical support of the shop where I buy it they are telling me that it is the hard disk or ram and that I probably lost everything on it and they are asking a big amount to repair.
    Can somebody advise me on this matter. Thanks in advance

    You can find the serial number either in About this Mc in the Menu bar under the , or it should be on a sticker under the foot of the machine.
    If you have the install discs, try booting from them, holding down the c key and then using Disk Utility to check the drive. 
    You can also boot into Safe mode
    To start up into Safe Mode (to "Safe Boot"), do this:
       1. Be sure the computer is shut down.
       2. Press the power button.
       3. Immediately after you hear the startup tone, press and hold the Shift key.
          Tip: The Shift key should be held as soon as possible after the startup tone but not before.
       4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
    During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
    During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
    Please post back with results,
    To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.
