OS X 10.8.3 fails to reboot - gray screen

After the 10.8.3 update I am unable to boot mac pro.
I get stuck on a gray screen after hearing the starting chime sound.
Nothing further happens.
My boot volume is a software RAID.
I tried:
-start up manager (option key)
-save mode (shift key)
-recovery mode (command R)
-verbose mode (command V)
-reset of NVRAM
I also had just tried to install a 10.6. system on an older mac via fire wire traget mode.
For this I tried to start my mac pro from the 10.6. disc, which did not work.
How can I reset to boot my mac pro from the internal software raid drives with 10.8.3 installed.
I also have a proper time machine back up, but would like to avoid an entire rebuild.
Would be very happy about any input!

Glad you got your Mac fixed. But I hope you realize that an update can always go awry; corrupted download, stray voltage spike in your AC power, even a bug in the Installer of the Update. That's why it's never a good idea to update anything that affects your business for at least a week or even two AFTER the update comes out.
And this applies not just to the OS Update, it may be even more important with an update to one of the apps you need for your business! 8-| There's hardly ever a valid reason to make an Update while working on a clients task. Certainly no reason to make an Update during the work week. That's what Week Ends are for! LOL!
Basic rule for the OS Update, for me, anyway, is to NEVER use the Software Update version. I ALWAYS go to the Apple site and download the Combo Updater. It's often much larger, but it's never failed me. Maybe just that fewer people are hitting that server! Who knows? Who cares?
Second basic rule, WAIT a few weeks to see if there are problems associated with any update. What's the advantage of being the first one on the block with a problem?!
Third basic rule, try the download a second time. Bits/electrons are very slippery! Some have been known to fall out of the Internet "tubes!"

    Every time a query is sent to the MP, it receives 0x80072ee2 which translates to "The operation timed out". This has nothing to do with your MP or DP though so reinstalling them won't make any difference.
    This error is indicative of network issues -- basically, the "client" is not getting a response back in a timely manner (and probably not at all). Assuming the MP is healthy though, then only other piece of the puzzle is the network.
    You can try setting the SMSTSAssignmentsDownloadRetry and SMSTSAssignmentsDownloadInterval task sequence variables in the boot image to increase the client's tolerance for latency or other weirdness in the network. This has worked for many.
    If that doesn't work, you'll have to break out a sniffer and watch the traffic to see what's going on at a network level.

  • PC fails to reboot and shows blank screen after automatic windows updates including SP

    Pavilion- a1130n"  WINXP ProfessionalC fails to reboot and shows blank screen  after automatic install ing windows updates including SP 3

    I would love to say that a refresh worked for me however it did not.It takes about 30 Minutes total I was able to trace part of the issue to a Registry Key that was tagging the processor. Because my BIOS manages its own temp gauge and windows is trying to
    build on in I had to turn the BIOS one off as well as for some reason I get better funtionality with Visualization off.
    I am still dealing with a lag but I was able to get ride of the freeze that made the computer completely useless.

  • Compaq CQ56 Laptop/Will not reboot/black screen

    Hi...I am new to this forum...I have a Compaq CQ56 laptop....just recently while updating my spyware and installing my updates, when the system reboots the screen remains black....I launch the system repair...it takes  me to the system restore window...did the system restore and the computer rebooted just fine....however everytime I need to install an update and reboot...I run into the same issue each time.  Ran the Hard disk and Memory diagnostic test and that passed without any issue.  I did notice a loud noise which I assume was coming from the fan....not sure.  
    Update for Windows 7 for x64-based Systems (KB2762895) failed at the install.  Is there another fix outside of having to take in for repair?
    Thank you for your time

    Hello Nana53
    Do you only run into the problem when you try to install just the Windows 7 update (KB2762895) or does it happen when trying to update any application? You said the screen is black, so how did you perform the system repair? Are you referring to the black screen as the screen goes black while windows is trying to load and you do see the BIOS and boot options?
    Searching the internet I have found mixed feelings and problems with users installing the Windows update. It seems to be meant to improve compatibility of programs, however, some applications aren't liking the changes.
    http://goo.gl/ZNBsQ
    In your case it isn't working. You can hide it from view so that you don't need to update it. This should prevent the problem from reoccurring. Hide Windows 7 Updates that you do not Ever Want to Install

  • MacBook keeps rebooting, grey screen and unable to get a log in screen

    Have no idea what has happened! Looking through mail yesterday, nothing else. When I went to log in last night it started rebooting and then shut itself off. Every time I try to turn it back it on it has grey screen, apple icon and begins to reboot itself and then simply turns itself off again. Cannot even get to log in screen. Any advice on how to get my log in screen back and stop this process?

  • MBP has gray screen on start up, won't reboot

    I bought a used MBP (early 2011) with OS X 10.6.8. It's been running just fine, but last night moving files the screen suddenly went black. I rebooted and it will come up to a gray screen and then sit there. The fans start revving up and it gets really really hot. Of course I haven't done a backup recently, so I need the information on the computer. I am hesitant to return it (under warranty) for fear of not recovering my data. Help!

  • Will not reboot gray screan

    I boot up no sound apple shows wheel turns disappears nothing happens.
    Boot it up with my mac book pro on a fire wire comes up fine makes sound on bootup

    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. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.   
    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 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.”
    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. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    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.
    If you've booted from 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. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    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.
    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, empty the Trash, and then open the Finder Info window on your boot 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 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 Step 1.) 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 may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
    Step 6
    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.
    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
    A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
    Step 9
    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.

  • Bought IMAC sept2012 after updates gray screen shows up with logo at start up. Please help! I don't know the system as I just start using it and the package did not come with CD to reinstall system. I tried to reboot holding shift but it does not work.

    Please help.

I tried to reboot holding the shift key without success. The package did not come with a CD so I can not reinstall the previous system.

HELP PLEASE, how can I get the previous system so I can reinstall it? I do not mind loosing data but I need to work on it. PLEASE HELP! Thanks!

    Try booting into the Recovery HD which is on the HD. Restart holding down Command+r and at the screen with four choices select Disk Utility>Macintosh HD and click on 'repair disk'. If any changes are made click on repair disk again until you get a clear pass. Restart as normal from the Apple menu.

  • I installed an software Update on my MacBook Pro and after that my laptop wont reboot passed the gray screen?

    After installing a software update on my Macbook Pro, it would not reboot passed the gray screen and then would shut down.

    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. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.   
    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 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.”
    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. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    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.
    If you've booted from 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. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    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.
    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, empty the Trash, and then open the Finder Info window on your boot 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 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 Step 1.) 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 may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
    Step 6
    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.
    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 Time Machine or other backup.
    Step 8
    This step applies only to a Mac Pro tower, not to any other model. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
    Step 9
    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.

  • Virtual box xrandr - failed to change the screen configuration

    I am using Arch as guest in the Virtual Box
    xrandr -q says 36000x36000 is the maximum mode.
    I want my screen to be of maximum mode 36000x36000 which will is needed in my project.
    IN my xorg.conf I have added the mode 36000x36000 but when I try
    xrandr -q it shows 36000x36000
    but when I try xrandr -s 36000x36000 it says
    failed to change the screen configuration

    do you have enough video memory allocated to the virtualbox?  i'm guessing it would take a lot of video ram to produce such a high resolution.
