Question mark appears on stsrtup

Macbook Pro 13" Has worked perfectly 1.5 years. Froze last night, forced quit. This morning after powering on, a question mark appears on screen. What does this mean? Can I repair it? Thank you.

I believe the question mark means the computer cannot find a viable operating system. This could be because of some disk corruption.
So, if this happened to me, the first thing I would try is booting from the Mac OS X installation disk. From there you can run Disk Utility and verify/repair the disk. Run the repairs repeatedly until Disk Utility reports no errors and tells you "The disk appears to be ok." (or something like that).

  • My macbook fell and since then a white screen with question mark appears

    hey guys!
    i really need to know what to do, my macbook fell while it was on. it froze so i restarted it, but the white screen comes in with the apple begining sound and everything but the screen stays blank for about two minutes and then a folde with a question mark appears. i tried putting in the cd that came with it, samething happened but after a while the appe sign appears and the computer started off my installation disc, so i try re installing everything, but when i get to the screen that asks to select a destination, there is nothing available.
    i realize that the best thing to do is to go to an apple store and then sort everything out, but i am in haiti where the nearest apple store is in miami, i really need your help and i'm desparate cuz i cannot do anything without my laptop... please send me your help as soon as possible.
    thanks in advance

    Your hard disk has been damaged. At this point, it will need to be replaced with a new one. You'll need to call AppleCare and they'll have you mail it in for repairs. I'm not sure what the usual turnaround time for that is internationally, but in the United States it's about a week. I'd tack on a few extra days to get the laptop to and from Haiti.
    Either way, your computer will need to be repaired and the data that was on your hard disk will be lost. (Unless you take the machine to a 3rd party repair shop that specializes in recovering data from damaged hard disks.)

  • HT1379 A flashing question mark appears when I re/start my MacBook Air 2013. At first, I pressed Power & Option button and it recovered from Internet. Then, four options appeared but none of them are helpful. Could u please help me to solve it asap?

    Hello,
    A flashing question mark appears when I re/start my MacBook Air 2013. Then, I pressed POWER & OPTOIN buttons and internet options appeared for internet recovery. After internet recovery, the OS X utilities appears with four options (Restore from Time machine, Reinstall OS X, Get help online and Disk utility). But none of them seemed helpful. On the last option Disk utility, the icon created only with 33KB and other disk 1 Mac Os X Base system. On First Aid, the icon Repair disk is disabled. So I could not click on repair disk. Could you please suggest me how to solve this problem asap? Thank you so much for your help in advance!

    You can try the following:
    Install or Reinstall Lion/Mountain Lion from Scratch
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard 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.
    Erase the hard drive:
      1. Select Disk Utility from the main menu and click on the Continue button.
      2. After DU loads select your startup volume (usually Macintosh HD) from the
          left side list. Click on the Erase tab in the DU main window.
      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
            the Security button and set the Zero Data option to one-pass. Click on
          the Erase button and wait until the process has completed.
      4. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.

  • Had an Excel file in the dock. When I restarted  computer a question mark appeared in the dock. I can't find the file. Where can I find what was in the dock on my Time Capsule

    I had an Excel file icon in my Dock on the compter. When I restarted my computer a Question mark appeared where the file icon was located in the dock. I need to find that file. I can't locate it either on my computer or on the Time Capsule . Anyone have any thoughts where the actual file may be located?

    Sorry, you lost me.
    If the file is on your computer, then you will find it if you open Excel, click the File menu, and click Open Recent.
    If you deleted the file before Time Machine saved it, it is gone.
    If the file was on your computer long enough for Time Machine to save it, it will be in your Time Machine backups.
    Open up Time Machine, wait a few minutes for it to load, and click on All Files on the left side of the window.
    Then scan to select a purple bar over on the right hand side of the window to select a recent date when you know that the document was on your Mac.
    If the document was saved, then you will see it in there somewhere. Click on the file to highlight, then click Restore to bring it back to the present time.

  • Blue Question marks appear...

    Blue Question marks appear when websites like Facebook have pictures.  This began after Uverse was installed in my home.  It did not do this previously with ATT High Speed Internet.  Uverse claims this is a computer issue.  SOMEONE HELP!
    Yes my computer is updated.

    Hi..
    If you are using Safari, from your Safari menu bar click Safari > Preferences then select the Appearance tab.
    Make sure the box next to: Display images when the page opens   is selected.
    If that box was already selected, back to the menu bar click Safari > Empty Cache
    If that doesn't help, try Safari > Preferences > Privacy
    Click:  Remove All Website Data
    Quit then relaunch Safari to test.

  • IMAC won't start. Folder Icon With Question mark appears

    it will also not take the startup disc. I plop it in , hold 'C' ket to make a disc repair fut nothing happens, now screen is all grey.

    HI,
    A flashing question mark appears when you start your Mac
    If nothing at the link above helps, try booting while holding down the Option key. That will prompt the Startup Manager window.
    Since you can't boot from your install disk, Start up in Safe Mode

  • Mac does not start and a cartel with a question mark appears. what does it means?

    it's the second time it happens. I start Mac and a folder with a question mark appears, then I close and restart and Mac opens normally. What's going wrong? Thank you for any help

    Welcome to the Apple Support Communities
    The question mark appears when your Mac can't find a bootable volume to start from, and it may indicate that your hard drive is failing.
    Open Disk Utility, select Macintosh HD in the sidebar and verify the disk. If it finds a problem, you will have to repair the disk, starting your Mac from the Snow Leopard DVD

  • Question mark appearing in place of photo

    Question mark appearing in place of photo. Happened after upgrading to iPhoto '11.

    Question mark suggests a permissions issue. Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair Library permissions.

  • Question Mark appears in finder

    When open to finder and going through any folder a gray question mark appears between the gear looking icon and the search bar. When the question mark is clicked a window pops up stating "The item can not be found" however all my files and everything are all there however. No matter what is selected the question mark still appears

    Hi,
    you must have had a shortcut in the Toolbar, and the link has been broken - you can safely remove it without harming your system.
    To do this, right-click (ctrl-click) on the Finder Toolbar, and choose "Customise Toolbar" You can then drag the "Question Mark" out, with your mouse, and it should disappear in a puff of smoke.

  • After reformatting drive - folder with question mark appear

    I am using an iMac 2010
    I was planning to reformat it and install the OS Maverick from my drive but after formatting (which delete all the files from it's hard drive) after restarting a blinking question mark appears
    I have a wireless keyboard and mouse and I am trying to boot it with a CD of OS X 10.6.4
    nothing is happening when i press option c , command R ,etc
    what should i do?

    Hi,
    - Try booting with the Option key and select the Install CD in view: Startup Manager: How to select a startup volume
    - If the Option key does not respond with Starup Manager, try with a wired keyboard.
    See how you go

  • I keep getting an intermittent error on web pages where a blue box with a question mark appears instead of pictures.  For example Facebook and Zappos would load normally on one visit, but if I visit other websites and return I get the blue box.

    I keep getting an intermittent error on web pages where a blue box with a question mark appears instead of pictures.  For example Facebook and Zappos would load normally on one visit, but if I visit other websites and return I get the blue box instead of pictures. If I restart the problem will go away temporarly. However, normally returnes in time.

    HI,
    From the Safari Menu Bar click Safari/Preferences then select the Appearance tab. Tick the box next to: Display images when the page opens.
    If that box is already ticked, from the Safari Menu Bar, click Safari / Empty Cache. When you are done with that...
    From the Safari Menu Bar, click Safari / Reset Safari. Select the top 5 buttons and click Reset. Relaunch Safari. If you still have problems loading images, go here for trouble shooting 3rd party plugins or input managers which might be causing the problem. Safari: Add-ons may cause Safari to unexpectedly quit or have performance issues
    Web pages now include a small icon or 'favicon' which is visible in the address bar and next to bookmarks. These icons take up disk space and slow Safari down. It is possible to erase the icons from your computer and start fresh. *To delete Safari's icon cache using the Finder, open your user folder, navigate to ~/Library/Safari/ and move this file "webpageIcons.db to the Trash.*
    Make sure Safari is not running in Rosetta. Right or control click the Safari icon in your Applications folder then click Get Info. In the Get Info window click the black disclosure triangle so it faces down. Where you see Open using Rosetta... make sure that is NOT selected.
    If you still have problems, go to the Safari Menu Bar, click Safari/Preferences. Make note of all the preferences under each tab. Quit Safari. Now go to ~/Library/Preferences and move this file com.apple.safari.plist to the Desktop. Relaunch Safari. If it's a successful launch, then that .plist file needs to be moved to the Trash.

  • Audio and video files dont play on wiki only a qicktime icon with a question mark appears

    I have many users on my server who upload podcasts, but the problem is that the audio file they upload doesnt always play. Only a quicktime icon with a question mark appears. What is also very strange is when you refresh the page usually the file will play and it will work on a Mac but then sometimes not on a PC, and the files always play without a problem on iPads and iPhones.
    The icon looks something like this. PLEASE HELP!

        The same thing happened to me last night, except for with video.  Playing videos used to work fine on all operating systems.  Now it will work on Windows and iPhone/iPad but only some videos work on my Macs.  After searching for hours here is what I found:
    1. Go to Safari preferences, Security Tab and uncheck "Enable Plug-ins".  When I tried to play video after doing this the Quicktime question mark went away but the video didn't play, it just turned into background color and I can't even right click on it.
    2. Run Safari in 32-bit mode.  Locate the Safari file in your Applications folder.  Right click it and click Get Info.  Check the "Run in 32-bit Mode" box.  Restart safari.  This did nothing for me.
    3. Try a different web browser.  I tried Safari, Chrome, Firefox and Opera.  They all do the same thing.
    4. As for codecs, I updated then reinstalled Flash, DivX and Flip4Mac.  Still doesn't work on Macs.
    I know it's not a problem with the server because it works on Windows and mobile devices.  Another weird thing is certain .mp4 videos work fine but some won't.  I re-uploaded them and made sure the video worked on the server and the file is fine.  All regular websites work fine: Youtube, Apple, etc.
    My only guess, since this suddenly happened on all my Macs, is that there was some update that caused this.  All help is appreciated.

    NEW TO APPLE MY IMAC SHUTS DOWN THEN A QUESTION MARK APPEARS THEN IT RESTARTS HAPPENED A FEW TIMES ANY IDEAS IT DOES SEND A REPORT TO APPLE THANKS

    Question (?) Mark, Blinking Folder, or Gray Screen at Startup
    These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
    A flashing question mark appears when you start your Mac
    Mac OS X- Gray screen appears during startup
    In most cases the problems may be caused by one or more of these:
    a. Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
    b. Boot drive's directory has been corrupted - Repair with Disk Utility.
    c. Critical system files are damaged or deleted - Reinstall OS X.
    d. The disk drive is physically non-functional - Replace the hard drive.
    Note that the information I have provided is what Apple recommends, If other users suggest different solutions than found here, then be sure what they recommend does not impact on your warranty, if any, or ability to get continuing Apple service.
    Please don't start removing drives or changing cables unless you know what you are doing and have exhausted other non-invasive alternatives outlined here. If you perform any work yourself that is unapproved by Apple, then you will void any warranty you may have and lose all further Apple Support.
    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.
    The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.
    Reinstall Snow Leopard Without Erasing The drive
    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.

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 Mac OS X 10.6.8 Update Combo v1.1.
