Repeated Authorization of DRM Video displays gray screen with no sound

I recently loaded the digital copy of Watchmen included with the Blu-Ray package. Every time I attempted to play it, iTunes authorization would be required and a message would indicate the system was already authorized. The movie would "play" with a gray screen and no sound, however the preview screen would show a still of the current scene. The movie could be loaded on my iPhone and plays normally. All my previous DRM purchases now display the same gray screen with no sound.
The problem was caused by /Library/Quicktime/QuickTimeComponents.component
In my case, this was an obsolete 7.2 version
I removed the file, rebooted, and the problem was solved.
Restoring the file, will make the problem return.
The problem could be reproduced on both a G5 and Intel Mac.
There are many posts about similar gray screen (or grey screen) issues, but there seems to be many different causes. A similar issue exists with a 3ivx component which is also stored in /Library/Quicktime/ -- so I systematically removed components until the problem was solved. Some components are also located in /System/Library/Quicktime/

What I had to do was trash my Quicktime application. 
Goggled "Quicktime"...Since my operating system was "Lepoard" 10.5.8 - I downloaded and install QuickTime 7.5.5 for Leopard and let the install do its trick...
Once the machine restarted I went back to Apple QuickTime support page and downloaded the update QuickTime 7.7 for Leopard - let the install do its trick and after the restart I opened my movie download file in Quicktime and "BLAM!!!" it worked...THANK YOU!
Funny Apple QuickTime folks didn't know how to solve this issue...its nothing new and they are to be in the "know". The ineptness...wasting over of two weeks of my time emailing back and forth, then waiting a day in between for a response is unforgiveable.
Again THANKS...

  • Video displays weird colors with normal sound

    I recently downloaded the newest version of quicktime (itunes said it was required) and also service pack 2 because that was required for the newest quicktime, but now when I play videos, they are playing (I can hear the sound), but the video is just a weird display of colors and shapes.

    Open the QuickTime Control Panel / Advanced tab and check the box for "Safe mode".
    Quit and relaunch QuickTime Player and try the files again.

  • My iMac won't boot, get a black screen with alarm sound, then gray screen with start up sound, then repeats

    this problem started last fall after upgrading to Mavericks. If I shut down my computer (or restart) I have problems getting it going again. This is getting progressively worse. I hadn't shut down in over a month, forgot about this issue and shut down (which I used to do daily), so now I can't get my computer to boot. When I hit the power button I hear it starting, then a loud alarm sounds, then a long pause then start up sound with a gray screen with a progress bar. Once the progress bar fills, the screen goes black again for a bit. This whole process will repeat until I get frustrated and force - shut down by holding the power button. I have tried reseting the pram, starting up in safe mode, starting up with the command - R, starting up with my original install disc... none of it works. I'm at a loss! I do have an external hard drive that I have been using for Time Machine, but it's not recent because the disc needs repairs and I hadn't gotten around to buying a new HD to back up to first. Has anyone else had this problem? I really can't afford a big repair/replacement bill.

    A long, steady, load tone followed by a progress bar can indicate it is trying to install a Firmware Update.  Any other Tones would be multiple beeps and show an error code.
    http://support.apple.com/kb/HT5860
    You can also see a progress bar similar to booting into Safe Mode. However, the firmware update bar is thinner vertically than the Safe Mode bar.
    http://support.apple.com/kb/ht1455
    Either way, I would say something is wrong and it would be better evaluated at an Apple Store as Kappy points out.

  • Can someone help me with my 27" iMac's Gray screen with 5 Pink Vertical Line Problem?

    Hi there,
    I'm new to the forums, but I have a serious problem with my nearly 4 year old iMac 27" model.
    I was using my iMac one evening and then suddenly everything displayed on the screen gets immediately pushed to the left of the computer screen. Then after a minute, my screen turns a solid gray, displaying no dock, no header bar, no options, and the keyboard and mouse suddenly disconnect.
    When I turned back on my computer, it seemed to boot up perfectly normal. The normal gray start-up screen displays:
    Then it displays the Apple logo and begins to spin the loading circle icon below it. But this time it adds 5 vertical pink lines down the screen from left to right. They stay in place the entire time:
    And then when the login screen finishes loading, instead of bringing up my Account and my Password text box, it displays just a solid gray screen with the same 5 pink vertical lines on it, as shown below:
    I've let it set for a half hour and nothing changes. During this time the keyboard and mouse seem to be disconnected, nothing seems to work with the screen or the computer itself. I hold the on/off button on the rear, turning it off and then on again. The same process happens with the boot up, the Apple logo appears, then the spinning loading icon below it, and then the vertical bars appear and the Apple logo and spinning icon disappear.
    Is this a problem with the screen that an external monitor hooked up to it might fix, or is it a graphics card problem? I didn't buy the extended warranty package for the computer and it's roughly 3 1/2 years old.
    Any idea what might cause this and how it could be fixed in the cheapest way possible?

    I have the same problem since yesterday evening.
    My google research found this:
    iMac (27-inch): AMD Radeon 6970M Video Card Replacement Program - Apple Support
    Maybe this is our problem. My iMac fits into this category.

  • Power Mac G5 (OS X 10.4 I believe) won't start-up, goes to gray screen with ? in a folder.... ideas??

    I moved a bunch of music from my external hard drive to my Mac's hard drive, I practically filled up the hard drive on the Mac. Then my Firefox crashed so I shut the computer down. When I try to restart It stops at a gray screen with a folder in the middle. The folder alternates between having a "?" in it and the "Finder" picture.
    I read this link http://support.apple.com/kb/ts1440 but it doesn't help. I can't select a drive or anything because I'm just stuck at this gray screen. Is there a way to boot this up in "safe mode" or something so I can do something to it? I am worried that some of the music I moved from my external hard drive had a virus or something and it killed my computer.
    I got this Mac 2nd hand so I don't have a manual or any startup disks or anything..... What do I do????

    Yikes, no startup Disc!
    You don't want to have less the 10-20 GBG free space on your boot drive, OSX will be slow and/or start trashing files/data due to corruption.
    Reboot, Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when complete.
    If that doesn't work...
    Tough without the Tiger Disk problems, but try fsck...
    To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
    1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup.
    Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
    2. At the command-line prompt, type /sbin/fsck -fy
    (SPACE between fsck AND -fy important)
    3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
    The volume (name_of_volume) appears to be OK
    If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
    ***** FILE SYSTEM WAS MODIFIED *****
    Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
    4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.

  • I am not able to use my Mac while FileVault is encrypting. Is it frozen on a gray screen with the apple logo. Is it actually encrypting?

    I have an early 2008 MacBook and running iOS Lion. I just turned on FileVault and restarted my computer as instructed. It told me before hand that I would still be able to use my Mac while the files were being encrypted. However, when I logged in on the secure gray login screen, I was only directed to a plain gray screen with the apple logo in the center. There are no time turners or anything moving. Is my Mac encrypting or is it frozen in some sort of way? If it is encrypting, how long does it usually take? and if it is frozen, how do I unfreeze it?

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
    a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
    b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
    c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.  
    Step 10
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 11
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 12
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 13
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • My MacBook Air can't get past the gray screen with the apple logo. What's the fix?

    My MacBook Air can't get past the gray screen with the Apple logo, so I can't login. Does anyone know the fix for this?

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else.

    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
    a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
    How to back up and restore your files
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    How to use and troubleshoot FireWire target disk mode
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Before reconnecting an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
    Step 3
    Boot in safe mode.* The instructions provided by Apple are as follows:
    Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    When you see the gray Apple logo, release the shift key.
    If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    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.
    *Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
    When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
    If you can boot and log in now, reboot as usual (i.e., not in safe mode.) If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 4
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 5
    Launch Disk Utility in Recovery mode (see above for instructions.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it produces. Look for the line "Permissions repaired successfully" at the end of the output. Then reboot as usual.
    Step 6
    Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
    Step 7
    Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
    Step 8
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

  • My Imac is showing gray screen with red line when booting and restarts again

    My Imac is showing gray screen with red line when booting and restart again, I can load it in windows 7 safe mode with red lines across the display, pls help

    The graphic card is damaged. You can't do anything more than taking your computer to an Apple Store or reseller and getting your graphic card replaced.
    Sometimes, when the graphic card is damaged, operating systems can't start. That's caused because the drivers that make the graphic card work detect an error, telling the operating system that the graphic card is unusable, so the operating system can't start and it restarts. However, you can start in safe mode because operating systems use a basic driver in this startup mode

Every time I wake it up after the screen goes black or when I open the lid after I've been gone for a while, a gray screen with thin vertical colored lines appears (the lines are in different positions every time). I can hear sound when I press the volume buttons and I can eject CDs. Usually it fixes when I close it and re-open it. When I'm working with multiple monitors, it is nearly impossible to get out of- I have to unplug the Mini Display Adapter and THEN re-open it.
    All I have seen on the internet is to update your OS but mine is completely updated. Maybe the screen is going out? I've reset the PRAM and SMC with no luck.
    Any help would be appreciated, Kolton

    My March 2011 MBP did the same thing.
    After spending about an hour online with Apple Care without success, I did a reinstall of the Lion OS. It fixed the problem.  I was concerned that I would lose data or settings, but the reinstall was seemless and everything was the way it was before the reinstall except that the "black screen on wake" problem was fixed.
    I started the reinstall before I went to bed and it was waiting for me the next morning.
    Here is a link to the page on how to do the reinstall:

  • Mac Pro + 10.6.8 - gray screen with a forbidden sign & "still waiting for root device"

    Hi everyone,
    I've a Mac Pro Early 2008 Dual Xeon which runs 10.6.8  version of OS X (Snow Leopard)
    After a recent reboot the system won't come up, it just hangs displaying a gray screen with a forbidden sign instead and the gray spinner spinning forever...
    I have tried: http://support.apple.com/kb/TS2570
    1) Disconnect, test peripheral devices and network cables ---> nothing
    2) Perform a Safe Boot ---> I got this screen
    3) Reset the NVRAM / PRAM ---> Nothing
    4) Start from your Mac OS X Install disc; use Disk Utility
    I have tried to boot from both installed SuperDrive holding the C key, but nothing! The Mac doesn't start from CD (very strange!!!) 
    5) Check your cables and power source
    They are OK, but nothing!
    6) Remove third-party RAM and internal hardware
    No third-party RAM is installed...
    7) Perform an Archive and Install installation of Mac OS X or
    Perform an Erase and Install installation of Mac OS X as a last resort
    I can't boot from installation disc....
    Any other idea?

    Guessing that your hard drive has left the building or your OS X system has. I would start by replacing OS X, if you can:
    Clean Install of Snow Leopard
         1. Boot the computer using the Snow Leopard Installer Disc.  Insert the disc into the
             optical drive and restart the computer.  After the chime press and hold down the
             "C" key.  Release the key when you see a small spinning gear appear below the
             dark gray Apple logo.
         2. 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 the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, set the format type to Mac
             OS Extended (Journaled, if supported), then click on the Partition button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.

  • Dreaded Gray screen with Folder and Question Mark (EFI Boot poofs away)

    Hey--
    I've had trouble with my Imac that I purchasd in 2005 for a year and a half or so.  I had a gray screen about a year and a half ago, went on vacation for a week, came back and it booted just fine.  Another time it went down, I did a safe boot and it came back.  I've tried Command-Option P+R before with some success.  I had a boot camp partitioned windows xp drive on there also (I don't know if this matters, but wanted to mention that).  I've also tried putting the installation disk in there with no luck (thinking it would find the software on it)
    I put it away because I moved and dragged it out of storage to see if a miracle might have occured since the last time I tried 5 months ago.  Well, same thing--gray screen with a flashing folder with question mark.  I read in the discussions to hold the option key down to select a book device.  I tried this and got an EFI Boot icon with a mouse pointer, but when I go to select it it "poofs" away (literally, the icon POOFS away) before I can select it with the mouse pointer icon. 
    Has anyone seen anything like this or have any suggestions?  I guess I'm at my wits end and am ready to haul it down to the Apple store to get the prognosis (I'm sure it will not be good--probably shot hard drive or something).  I'm hoping this can be salvaged without much cost.
    Thanks so much for any advice or input you might have.
    Chris

    How to Perform an Archive and Install
    An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
    1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
    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, Leopard or Snow 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 restart normally.
    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. 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.
    3. 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.
    4. 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.
    5. 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.
    6. 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.
    If yours is an Intel model, then I recommend getting Snow Leopard to upgrade OS X, but I would recommend first erasing the drive before installing Snow Leopard.
    Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
    You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
    Upgrading to Snow Leopard
    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
         Snow Leopard General Requirements
           1. Mac computer with an Intel processor
           2. 1GB of memory
           3. 5GB of available disk space
           4. DVD drive for installation
           5. Some features require a compatible Internet service provider;
               fees may apply.
           6. Some features require Apple’s iCloud services; fees and
               terms apply.
    Upgrading to Lion
    If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
    You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax.  It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
         Lion System Requirements
           1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
               or Xeon processor
           2. 2GB of memory
           3. OS X v10.6.6 or later (v10.6.8 recommended)
           4. 7GB of available space
           5. Some features require an Apple ID; terms apply.
    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion - System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
             3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
             4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
             5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
             6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
             7. Xserve (Early 2009) - Model Identifier 3,1 or later
    To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
         Are my applications compatible?

  • My MacBook Pro stated that it needed to be updated. I clicked yes to restart the computer and update but when it restarted it stays on the gray screen with the apple logo and then pops up, stating "unable to find driver for this platform." What do I do?

    Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with networks that require any kind of authentication other than a WPA or WPA2 Personal password.
    When the Mac OS X Utilities screen appears, follow the prompts to reinstall the Mac OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac didn’t ship with Lion, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
    Don't install the Thunderbolt update -- it's defective.

  • Can't get past gray screen with progress indicator... Help

    I can't turn on my Macbook. It starts but won't go past the gray screen with the progress indicator (spinning circle).
    I have tried:
    1. turning off, removing battery, holding start for 5+ seconds, replacing battery and then turning on.
    2. Holding command + option + R + P while staring up, waited for 3+ chimes.
    3. holding Shift down while starting up
    none of these things are working.
    I've been on hold with apple service/support for almost an hour now.
    I have an assignment on the computer that is due by midnight.
    HELP!
    I'm not very computer savvy and this is my first mac.
    Any ideas folks??
    Thanks.

    You've done all the standard procedures. If you have any peripherals attached, disconnect them.
    This describes resetting the PMU:
    http://docs.info.apple.com/article.html?artnum=303319
    Did you have the AC disconnected when you did it? I don't have any other ideas.
    These are the startup key options:

    Edit: If you have the install disc stuck in it anyway, can you get the hardware test to work? (Reboot while pressing the D key.)
