    Click here and follow the instructions. If the computer originally shipped with Mac OS X 10.6.8 or earlier, when you reach step 5, insert its original disk, restart with the C key held down, use the Disk Utility to erase the internal drive, and install a fresh OS.

    There is no installed OS or you have a dead hard drive. Start by booting from the original installer disc that came with the computer or an installer disc that has a later version than the original such as a Snow Leopard DVD. Then you can do this:
    Reinstall OS X 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. (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.

  • In trying to reinstall OSX to our Mac Mini, the computer accepts, reads and then rejects the disc, nothing but blue on the screen.  What should I do next?

    Our 2009 Mac Mini became quite sluggish and then just wouldn't function.  I tried reloading the OS with the original disc from Apple, but the computer rejected the disc and the screen was all blue.  Next, I shut down the machine, inserted the disc, turned it on, the screen is a faint gray in color, Apple logo in the middle, the disc came out.  What should I next try? 

    Apple logo in the middle,
    The Apple logo is not contained in your Mac's ROM. Seeing it indicates that your Mac found a bootable device, and loaded the initial blocks from that device. I expect you booted from the damaged hard drive.
    Use the Option key held down at Startup to get clarity over exactly what drives can be seen, and what your Mac thinks they contain. Wait for it to draw an icon for every potentially-bootable Volume. Deliberately select the device you want to use as the Boot Drive.
    You must have a wired keyboard plugged directly into the chassis to use snag keys at Startup. A wireless keyboard that is already paired can be used, but the exact timing is more difficult.

  • I have an ipod touch 2nd generation that needs the screen fixed because the left side quit working any Idea on a price

    The left side of my screen quit working any idea what the price on a replacement costs?

    Apple will exchange your iPod for a refurbished one for this price. They do not fix yours.

  • My iPhone has a black screen I started to charge it yesterday and it wouldn't charge and I tried to charge it over night. But it is still black I've tried to reboot and still nothing  HELP!

    I tried to charge my iPhone yesterday and notice that it wasn't charging. And I plugged it in when I got home and when I woke up it still had a black screen. I have tried to reboot. And it still does want to come up.

    Yea, unfortunately the cost is quite a bit. Maybe cheaper to check your upgrade eligibility through your carrier or try craigslist?
    Just be careful on the craigslist, people will try to sell you ones that are locked to someones apple id already.

  • My Late 2013 iMac with Yosemite 10.10.2 randomly shuts down and displays a grey screen with a flashing question mark folder. According to Disk Utility, my drive is OK. What should I do?

    I've had this problem for a while and I thought it went away. I've looked at all of the other discussions and tried what they suggest, nothing. I preferably don't want to erase everything on here. Is there a way to fix it without having to do that? I also noticed that other people have the screen when they first boot their computer. Mine are in the middle of a college essay or browsing online. I would really like to fix this issue. I haven't even had my iMac for a year yet. Any suggestions?

    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

    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.

  • IMac with flashing Question-Mark Folder

    I've read all of the help on the flashing Question-Mark Folder.  Nothing has helped.  In fact, Disk Utility only finds 'Disk 0' with the base OS X operating system.  All of the disk utility buttons are grayed out and at the top on the left of is 'Media' (not disk drive - not formatted?).  When I try to recover from the internet and re-install OSX Maverick, it can't find a disk to install on.  Does anyone know what happened and can this be fixed?

  • White screen with flashing question mark

  • Flashing question mark folder, 3 times this week on my imac : (

    My intel based 3.06 GHz imac this week is showing a flashing question mark folder. A friend says is that the hard drive is toast but well twice it was solved quickly. First time on monday I did commandoption+pr to reset NVRAM and it worked. Second time yesterday i pressed option during startup and i selected my mac os x volume. But well today nothing works : (
    This flashing question mark is constantly showing up. any ideas how to force my imac to select the hard drive mac os x as the startup disk?
    this doesnt work:
    1. pressing option to select startup disk as i did yesterday.
    2. when trying to boot from mac os x install disc pressing c during startup the imac ejects the dvd.
    3. trying to start up in safe boot mode (pressing shift), verbose mode or single user mode all fails, just the flashing annoying question mark folder again.
    I was reading that i could use ubuntu live-cd to transfer my data from ubuntu to an external hard drive. I downloaded, burned and then it does shows the ubuntu cd to install ubuntu (the mac os x install disc is ejected but the ubuntu cd works), but i really dont want to install ubuntu X_X I just want my imac back without installing any linux stuff.
    I can do target mode with my other macs but the imac hd doesn't show up in the other macs, any way to force the HD to show via target mode in the other macs?
    Any ideas? I guess my disk is failing and thats why i have been receiving these question mark folders 3 times this week.
    Message was edited by: AppleSensei

    if someone has the same issue, i just want to notice i solved it using ubuntu -linux- and transferring the files to an external hard drive from ubuntu, reinstalling mac os x again. When i did target mode with another mac the hard drive didnt appear in finder, but with ubuntu all worked great, i saw my files and then problem solved, i saved my data ; )
    I did found annoying using ubuntu to solve this issue with my mac, but well i learnt something new, linux can also be useful when you don't want your data to be deleted as customer support told me they were going to do if i sent my mac.

  • G4 17' won't boot, flashing question mark folder with complications

    I'm editing a final cut pro project, due to air on friday at noon and during conversion in compressor to dvd format, final cut quits then the computer freezes up. On a hard restart I get the flashing question mark folder.... i know what that means
    I was able to boot up after a couple of tries from the os 10.4 (tiger) cd and the hard drive shows up but disk utility can't make the repair. This is the error i get:
    booted with the tiger os cd and got to the disk utility. the hard drive does show up with some generic-y looking name. I try to repair the disk and get this error (in red):
    Invalid node structure
    Volume check failed.
    Error: The underlying task reported failure on exit
    then it says:
    1 volume could not be repaired because of an error
    g4 powerbook 17" Mac OS X (10.4.9)
    so then i get the bright idea that i will change the startup disk to network drive and try to start from another drive on the network. it tries to find it then goes back to the flashing question mark. I've restarted holding the c key down with the tiger cd back in there and it is spinning but it never reads it.
    any ideas? I REALLY need to salvage this film if possible.
    thanks!!!!!
    donna
    Has anyone seen this before? What is my next step--short of erasing the drive. i really need to get this project off.
    thanks in advance for any and all help!!!!!
    g4 powerbook 17"   Mac OS X (10.4.9)  

    i'd try disk warrior except that i cant get it to boot from ANY cd right now EXCEPT apple hardware test. and i have NO idea what to do with that.
    I've tried booting in option mode and all i get is the little restart button and the forward arrow button but NO drive options
    it won't pick up my other laptop in target mode
    i've even put in Norton Utilites 8.x and it won't boot up from that either.
    i've zapped the pram--nothing
    know of any other boot tricks or shortcuts?

  • I dropped my iphone 3gs and the screen has gone blank now showing a white screen with no icons can anyone advise me how to fix it?

    I dropped my iphone 3gs and the screen has gone blank now showing a white screen with no icons can anyone advise me how to fix it?

    Tim is correct.
    But, first step with 3GS white screen and most iPhone problems is Reset, hold both home and power buttons until iPhone begins to restart itself, usually about 10 seconds of holding both buttons. If still white screen.
    Next step would be Restore the iPhone Firmware with iTunes on your computer. If still white screen.
    Next step would be to follow Tim's advice, if you had not already.
