MacPro doesn't start and stays on white screen with apple logo.

My mac pro does not start. It turns on because I hear the sound, Then the apple logo and progress bar appears. The progress bar does not load fully. I have done all the troubleshooting that is to be done including disk verification, disk repair, single user mode, set SMC and VPRAM. Nothing has helped. I have not backed up my files.

Hello ashmifromnolensville,
Welcome to the Apple Support Communities!
I understand that your Mac is only starting up to a grey screen with the Apple logo. I don’t want to have you complete troubleshooting steps that you have already completed, but for completeness sake, I would advise reading over the attached article and completing any suggested troubleshooting steps that you have not completed.

    i upgraded to yosemite last week, now my computer wont start. it stops at white screen with apple logo. what do i do?

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
    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 a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
    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 in OS X 10.9 or earlier, 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 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...

  • Computer doesn't boot, stuck in white screen with Apple logo

    I got a friend that has a MacBook 2.0GHz, Black. The computer had some sort of problem so he took out the HD and placed it into another computer (MacBook 2.2GHz, Black). For some reason whenever the computer boots, it gets stuck in the white screen with the gray Apple logo, and shows up a bar, as if it's loading some sort of firmware update. It never advances, and it doesn't go thru.
    If he takes the same HD and puts it into an enclosure, first it would take a while to mount in another computer, and afterwards it would give some errors, but now it doesn't even load.
    Before he had the issue with his original computer everything was working fine, and there was no update going on when the computer got broken. The problem that that computer has isn't related to the HD.

    If you have physically removed the drive and connected it to another computer and it "took a while to mount" then it sounds like the drive itself is failing. Hopefully he maintains backups.
    Boot the MacBook in "verbose" mode (press and hold down option+v while powering up)
    http://support.apple.com/kb/HT1492
    In this mode you will see all the boot messages scroll by instead of the typical white screen with Apple logo. You will likely be able to see messages indicating what the computer is trying to do -- for example messages indicating that having failures or retrying to read the hard drive.
    The access arms on hard drives have to be precisely located above the "tracks" on the disk in order to read data. As the drive ages & wears, the accuracy of the arms can become sloppy, causing the read/write head to no longer be precisely located over a track. This results in failure to read correctly. Most drives have a useful life of about 5 years -- after which the failure rate will go up substantially. Fortunately, replacement hard drives are cheap.

  • Imac wont boot - i get a white screen with apple logo, and it loads to about 10%, then screen goes black

    imac wont boot - i get a white screen with apple logo, and it loads to about 10%, then screen goes black

    Hey there mtriest,
    It sounds like you are unable to boot the iMac successfully as it keeps shutting down when you try to boot. I suggest the troubleshooting from the following article named:
    Mac OS X: Gray screen appears during startup
    http://support.apple.com/kb/ts2570
    Disconnect, test peripheral devices and network cables
    Note: "Peripheral devices" refers to external devices other than what came with your Mac, such as hard drives, printers, or hubs that you connect via a USB or FireWire cable.
    Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
    Disconnect all peripheral devices such as external hard drives or printers (leave only the display, a keyboard, and mouse connected).
    Disconnect any Ethernet cables.
    Start up your Mac.
    If you can start up this way, one or more of your peripheral devices (or installed software related to the device) is probably causing the gray screen issue. Connect one device, then restart your Mac to test for the issue. Repeat the process until you locate the device at issue. Make sure the device is powered if it needs to be to operate correctly. Check with the manufacturer of the device for support or possible software driver or firmware updates that may be available for the device. Try a different cable with the device if possible (such as a different USB or FireWire cable).
    Note: If you have multiple peripheral devices and the issue only occurs when they are all connected, but not when each device is the only peripheral connected, see the Additional Information section below.
    If you are using a desktop Mac with a third-party keyboard and/or mouse device, and the issue still occurs, try starting up with an Apple keyboard and mouse connected instead. Try starting with no keyboard and mouse connected, then connect them after start up. Also, try a different USB port on your Mac.
    If the gray screen issue persists with no devices connected, go to the next section (with the peripherals still disconnected).
    Perform a Safe BootSimply performing a Safe Boot may resolve this issue.
    Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
    Start your Mac, then immediately hold the Shift key. This performs a Safe Boot. Advanced tip: If you want to see the status of a Safe Boot as it progresses, you can hold Shift-Command-V during start up (instead of just Shift).
    Note: A Safe Boot takes longer than a typical start up because it includes a disk check and other operations.
    If your Mac starts up as expected, immediately try restarting.
    If the Safe Boot does not work, or the restart after a successful Safe Boot does not work, go to the next section.
    There is additional information in the article with further troubleshooting if needed.
    Thank you for using Apple Support Communities.
