MacBook Pro Presents a Grey Screen & Restarts Over and Over

I just got my new 2.7Ghz i7 last tuesday and even after the first time I turned it on and completed updates, restarted, and I was just running safari and itunes, randomly a grey screen came up saying that I needed to restart the computer. I thought it was a one time deal, but then it happened on thursday. Now, today I was working on assignment on pages, with safari running as well, and then the same screen came up and I lost everything. And then it did it 2 more times within the span of 10 minutes, those times not even having anything running. It's been fine for the rest of today, other than having to restart my assignment since I hadn't saved it yet, but the things is I had my previous macbook pro 13" that I purchased in october 2010 and that never happened once. Now, I've had this one for a week and it's happened 7 times. What do you recommend? If I bought it online, can I bring it to a store to exchange it.

Hi clifton, and welcome to apple DIscussions.
I would bring it to an Apple Store asap and if it's not something simple, I'd ask for an exchange.

  • MacBook Pro has a grey screen with circle and slash and will not start up or start into safe mode.

    MacBook Pro has started to get a grey screen with circle and slash and will not start up or start into safe mode.  This happened once previously, however, it allowed a safe mode reboot and then worked for a week or so.  While utilzing the machine, it started with the spinning beach ball for about 5 minutes, went into a shut down mode and then rebooted and came back up with the grey screen with a circle and slash after a few minutes.  For the past three days it has been stuck and will not allow it to boot into safe mode.  Any idea or suggestions?

    Try starting the MBP with the OPTION key down.  If you see two HDD icons, select the recovery Icon.  From the 4 option menu, select Disk Utility.  Select Disk Utility>First Aid and run Verify and Repair. 
    If you cannot get into the recovery partition, make an appointment at an Apple store genius bar.
    Ciao.

  • My MacBook Pro shows a grey screen  at start-up how do I fix this problem?

    My MacBook Pro shows a grey screen when I try to login and won't go onto my homepage. Why has this happened and how do I fix 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.

  • Macbook Pro 2008. My screen stayed black and is unresponsive.

    Macbook Pro 2008. My screen stayed black and is unresponsive and sleep light is on. I shut down and then restarted and nothing happened on screen but sleep light came on and is solid.

    It could possibly be the video card, or the logic  board.  You could try a smc reset if you have not done s yet.   smc reset:
    http://support.apple.com/kb/HT3964
    I had an issue similar to this, and there was a bad logic board, hard drive and video card.
    You might want to bring it in to the Apple store, they do the diagnostic for free and give you a repair price.
    They offer a flat repair rate, which they fix what ever is wrong as long it was due to liquid damage.
    The repair cost me about 1/3rd the price of a new machine and the machine has been fine ever since.
    It's worth getting it checked out.

  • My Macbook Pro got the grey screen of death (kernel panic) and now it won't even turn on

    Hey.
    Well my macbook pro just got the grey screen of death and upon doing some research I unerstan that it's a kernel panic. However my issue is that my laptop won't reboot, at all. Whenever I try to press the power buttons, the external buttons will light up and the you can hear it running (barely, very low) but nothing else happens. My screen doesnt turn on and no noise comes from the computer to indicate it turning on. However if I hold the power button again it'll act as if shutting down (the noise). I've tried to look online but I havent seen any soluctions for my specific issue.
    Also note: I recently got it sent in for repairs and it was sent to apple, I was told they replaced both fans and the motherboard, however I'm not sure if that would affect it.
    Anyways, my mac is the world to me and I would hate to have to lose it, anyone have any solutions?

  • Macbook Pro stuck on grey screen with Apple logo

    Macbook Pro was purchased in mid-late 2009 and is running on OS X 10.6. Today is suddenly stopped responding and so I turned it off. When I turned it back on it opend to the grey screen with the Apple logo and the loading icon and that is where it stayed. I have been searching for the answer on different forums but have yet to find a solution. My hard drive is appearing in the Disk Utility but not in the box when I try to reinstall OS X. Any suggestions on what to do?

  • My 2014 MacBook Pro stuck on grey screen since trying to update software over an hour ago

    My 2012 MacBook Pro has been stuck on the grey screen for more than hour since I tried updating the software.

    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.

  • My macbook pro has the grey screen of death.... i have tried a few things to get it re started.... it is not backed up and i really dont want to loose everything on it :(

    MacBook pro has grey screen of death, it all began when I tried to install something new last night like my laptop asked and when it went to restart, it went grey....
    tried start up in safe mode and nvram/pram
    on safe mode it said ' the volume macintosh hd could not be repaired '
    My MacBook has not been backed up and it would be heart breaking if I lost everything from it...
    can anybody help?!!!

    Be prepared for a broken heart...
    It's obvious that you need a new drive - when you purchase one you should also purchase a USB enclosure for your old drive and connect that drive to your machine to see if you can rescue any data from it. You may have to purchase a utility such as Data Rescue 3 or DiskWarrior (each $100) to facilitate restoring some of your data.
    And start a couple of backup schemes... when you can't afford to lose data, a couple of backup schemes can help.

  • Macbook Pro boots to grey screen but won't start up. How do I fix it?

    Today I set my Macbook Pro on the couch but it slipped of and landed on its side (closed) on wood floor.  Nothing broke, it all seems pretty normal.  I pushed the power button to turn it on, but it only loaded to the grey screen with the apple and the spinning circle.  I left it sitting there loading for several minutes, but nothing happened.  I tried force shut down several times and restarted it.  It still did the exact same thing.  How do I fix it?

  • MacBook Pro 4.1 - Grey screen

    I use my MacBook Pro for work, it was passed down from the director who got a new one last year.
    Grey screen appeared about 2 weeks ago midway through working on it, telling me to switch off and restart. This kept appearing at the startup page (where the apple and loading wheel appear), eventually after holding shift at startup and giving it a reboot it started working again.
    I gave it to our works IT team who did a system check and said there was nothing wrong with it but to install some anti virus which i did, Avast and also used MacKeeper to scan my machine, which found 3 errors but then you need to pay for them to go further, which i did not do.
    On Sunday it took an hour for my computer to load up after trying about 20 times to hold shift at startup it eventually booted in safe mode, i got all the files off my desktop and saved to usb.
    Today, Tuesday, my computer is not loading at all for the past 2 hours. I have pressed shift, command and V and it starts up and gives all the behind the screens info (Im not technically minded) and it stops at...
    com.avast.AvastFileShield: Disabling Debug Mode.
    I have got a backup and had timemachine setup but i do not have the original discs.
    Is there any way i can use my time machine as i can not get on to the desktop to do this?
    Any other ideas will be greatly appreciated.
    I'm not sure what operating system it is either.
    Mac OS X and i only think its 4.1 as this is what appeared in the jargon when i have tried opening it with shirt, command and v. It is also no longer under warranty.
    HELP!

    I think that OGLETHORPE is writing about a replacement set of DVD's that would have come with your computer. About $20 last time I checked. You could boot from the installation disc (maybe) and restore your MBP to it's original state (which you may just have to do - good thing that you have backups).
    When you get your replacement disc(s) just boot from the installation disc, use Disk Utility to erase your drive (format as "Mac OS Extended (Journaled)" with a single GUID partition, and then use your Time Machine backup to restore your system as it was before you installed avast and MacKeeper.
    Call 1-800-MYAPPLE to order the disc(s). As OGLETHORPE says, you'll need your serial number as the disc(s) are machine-specific.
    Good luck,

  • Macbook pro stuck on grey screen and making buzzing noise

    hi,
    Lately my mac has been playing up (1 year old), ever now and then it would make a funny buzzing noise, coming from the left side..  and i noticed it was running slower than usual. Im Running Mountain Lion and have 566GB of disk space left... after using it for about 5 minutes the buzzing noise would start and it would become unresposive with the spiral beach ball.  So i would have to hard restart it.  Now ever time i turn it on it gets to a grey screen and doesnt load further. eventually the sound starts again!! i have tried starting it in safe mode and verifying my disk in utilities where everything "seems to be ok" !!    someone please help!!!  

    Ethan997,
    define “an average disk”.
    Your question regarding fault is akin to asking “is it my fault or the car maker’s fault that my spark plugs no longer work?” — disks, like spark plugs, don’t last forever, and fault doesn’t come into it. Similarly, the fact that your disk (or spark plugs) worked yesterday and doesn’t work today is not a sudden “breakage” — by their nature, they have a finite, variable amount of time in which they do work. This is why (in the case of disks) making regular backups is important; when the disk stops working, you’ll have an easy way to recover from such a situation.
    That being said, if your MacBook Pro is still under warranty, you should be able to get a replacement disk from Apple. And even if it isn’t, you could  still try reformatting your current disk, to see if you can squeeze some more use out of it — but if the reformatted volume keeps needing to be repaired (and you have the patience to deal with recovering from the same situation again and again), that’s a sure sign that a new disk would be your best option.

  • Macbook pro wont start. grey screen then shuts off

    I have been having some problems with my macbook when my battery would die and i would plug it in and try to turn it back on it would take forever to start back up. Sometimes i woudl have to unplug, take out the battery then put them back in and zap the pram and it would start. Then today it just started taking forever to restart so i shut it down and tried to restart now it starts goes to the grey screen and the little thing starts spinning and then about 5 sedc later it shuts itself down.
    PLEASE HELP

    If the Apple Hardware test does not bring up any problems with the hardware, I would advise doing an archive and install before you zero out the drive and erase all of the data on it.
    Some things to keep in mind:
    If your computer shuts down while booted to the install disk (either the AHT or the installer) you're looking at a hardware problem.
    If you need to erase and install or send it in for repair of a hardware problem, you will need to back up any data you do not want to lose before doing so. If you are unable to do backups, an apple store or authorized service provider can do data retrieval for you. Bear in mind this is an optional service and you would be charged a fee for data retrieval.

  • MacBook Pro boots to grey screen

    I have a non-booting MacBook Pro that will POST (Apple chime) and boot to a grey screen.
    I consider myself a pretty advanced troubleshooter but this one stumps me. Here is a summary of most of what I have tried so far, not necessarily in this order:
    Reset NVRAM
    Reset PMU
    Attempted to boot to DVD Command + C
    Attempted to boot to Target-mode Command + T
    Attempted to selected startup disc manually Command + Option
    Attempted to boot to SUM Command + S
    Attempted to re-image firmware using CD
    Attempted to boot diagnostic CD Command + D
    NONE of these work. I have fixed many Macs in my day and have not encountered an issue like this!

    I've been through both a logic board failure and a hard drive failure on my iBook, and neither had these symptoms. Since the article I referred to had to do with having no video, my guess would be that it is the logic board but I don't really know. It doesn't really sound like hard drive failure to me, or at least it's nothing like the way mine failed.
    Since the article wants you to reset the PMU in an older Mac, and I suppose the SMC in a newer Mac, I wonder if actually it is the SMC which has gone bad. The SMC is an integrated circuit after all, and if it were to go bad and not be able to be reset, then that might explain what's going on here.
    But I'm just speculating. It will be interesting to see what Apple has to say. Please let us know.
    Good luck!

  • Macbook Pro Late 2011 Grey screen

    Hi pals,
    I have a Macbook Pro Late 2011 since 2012. I've upgraded it to Yosemite, thing that I've to do from scratch because it worked very slow, but that's not the deal here.
    The other day I started it, and it simply didn't do it. I've tried everything, like Unique user mode, safe mode, starting from dvd, reseting PMU-PRAM-NVRAM, changing hard disk, changing RAM,... everything I've found in the internet.
    Only one thing worked once, and I say once, because it only worked once... I switch the HD and I used an USB to install Yosemite from scratch. It worked but when I reseted it, it never came alive again... That time, I used Disk Utility on Yosemite to format the original hard disk (700GB 7200rpm), and I recovered my personal data.
    Now, when I try to start it from USB to install or from HD it never works. It shows the progress bar till 1/3 and then the screen becomes grey, the CPU heats and the fans start to spin like crazy. Sometimes it turns off, sometimes it doesn't and I have to do it.
    Any help will be welcome, thank you .

    The colored lines  seem like it's a hardware graphics problem, likely brought on by the EFI firmware update that's been going around lately that exposed problems your hardware had you didn't know about.
    Your  going to have to bring this problem to Apple, I hope you have AppleCare because it's looking like a replacement logicboard and they are not cheap.
    You can try exhausting the remedies in my User Tip, but those mostly deal with issues from the gray screen onwards, the colored lines represent a firmware issue and Apple doesn't release the newest versions online for self reinstall until they have proven themselves.
    If your worried about sensitive data, you can order a tool kit from OtherWorld Computing, open the machine and remove the hard drive and use a SATA to USB connector to another Mac to remove data and scrub free space in Disk Utility.

  • My macbook pro 2011 shows grey screen with apple logo and want start

    i was just using my macbook pro and it freezed for a while not responding and i turned it off by pressing the power button. afterwards, i turn it on and it shows a grey screen with apple logo but want start pls somebody help me because am having "my life" on the machine

    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 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 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 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.
    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.* 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, 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
    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
    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.
