IMac won't get passed grey start up screen following power cut?

Hi,
I was working on a Word document when we had a power cut yesterday afternoon. They then said it was OK, the power came back on and I stupidly believed them and turned the iMac back on.
Within second, just as it got the grey screen with the Apple sign and little grey wheel, the power went again. It has been back all night, so have tried to get it started this morning and although it starts with the little tune and goes to the grey screen with the Apple sign and little wheel, after an hour nothing more?
I powered down and tried again holding down the Shift key as I started, but it the same, little grey wheel nothing else?
Please can anyone help me, i have just started my own business and am lost with it
Many thanks in advance.
Lynne

HI Anamusic,
Many thanks for the link I will save it, but unfortunately I have a wireless keyboard and tracker pad, so I don't think the keyboard is active when I need to use it, I have tried but it seems to be exactly the same.
Thank you for your help anyway.
Do you know if this something they might be able to fix in the 'Genius Bar' or will I have to take it to a Mac repair place?
Sorry never had problems like this before and just don't know what to do.
Lynne

  • Computer won't get past grey start up screen after install

    Okay - I made a stupid mistake. I started the installation process - it was taking a very long time so I decided to quit and free up some more space before trying again. When I quit it wouldn't let me go back to my old version - I think I was on 10.3.9. So I installed 10.5 - and it said it installed successfully. I restarted and the computer won't get past the gray screen. I let it go for 30 minute the first time, 15 the second time, and about an hour the third time. Won't go any futher. Any ideas?
    Thanks,
    -Brad

    same thing happened to me (you need to read all the posts as someone will have had the exact problem as you).
    any way,
    1. re-installl 10.5 from your leopard disk. (put disk in restart holding c key down etc). do not install OS just yet.
    2. run disk utility (it does not hurt-click on options button)- repair both disk and permissions
    3. run 10.5 installer (archive)
    4. download 10.5.2 combo from apple (that is if you can easily find it!)
    5. run that install
    6 it will restart two or so times
    7. total time is 20 mins or so. most of that is in repairs form #2.

  • 17 MacBook Pro is not booting up. Won't get passed grey screen with Apple wheel spinning below.

    17 MacBook Pro is not booting up. Won't get passed grey screen with Apple wheel spinning below.

    You may be having a hardware problem that you cannot resolve on your own. Nevertheless...
    ...hold down the command and R keys whilst booting to try to get to your Recovery partition. If you can, use Disk Utility to try to Verify your boot drive (usually named "Macintosh HD" unless you've renamed it). If the verification fails, try to repair your hard drive. If everything appears to be OK, restart.
    If you can't get into your Recovery partition, your problem is likely hardware related. If so, keep your appointment and see what the Apple techs have to say.

  • I am experiencing some major problems with my MacBook Pro. I have had some issues with it turning on/off at random times, but today, when starting, I get the grey start-up screen and a recovery bar. After filling in approx 1/4 of the way, the machine dies

    I am experiencing some major problems with my MacBook Pro. I have had some issues with it turning on/off at random times, but today, when starting, I get the grey start-up screen and a recovery bar. After filling in approx 1/4 of the way, the machine dies. After starting it in recovery mode, it will not allow me to download OS X Mavericks- it says the disk is locked. Any ideas? I do not have a back-up and do not want to erase everything before I have explored my options. Help?

    try forcing internet recover, hold 3 keys - command, option, r - you should see a spinning globe
    most people will tell you to do both pram and smc resets (google) and if you still have issues, either clean install (easy) or troubleshoot (hard)

  • My Macbook won't get past the start up screen

    Hey everyone
    I have a Macbook that's about 3 years old. I did an software update yesterday and since doing it the computer won't get past the start up screen. There's just the Apple logo and the rolling ball thing. It's been stuck there for around 30mins and nothing changes. I'm not really sure what has happened but I was wondering if there is any way I can fix it.
    Thanks for your time.
    Bevan

    Hey Lyssa
    I don't have a back up but I'm not to worried about that as it's my traveling computer and I only use it for the web and some word processing.
    I don't have the disks with me right now as I'm away from home. I'm not sure what I had updated, I think there was a lot because I hadn't don't it in a long time.
    If I can start it in safe mode what should I do?
    Thanks.

  • My iMac won't get passed white screen, My iMac won't get passed white screen

    Hi I was updating my iMac with mac os lion and it was installing the update when there was a power shortage and the iMac turned off. Now when I turn it on it won't get passed the white screen with the Apple logo and the turning thing, what should I do?
    The update I was doing was the Mac OS X Update Combined version 10.7.3

    I'll assume you have backups of your data. Boot from your recovery partition (command-R at startup) and reinstall the Mac OS. You don't need to erase the boot volume. 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.

  • G5 Quad won't get passed grey screen and spinning icon

    Hi,
    I can't seem to get my G5 past the grey start up screen. I hear the drive making a similar noise over and over again. I tried booting from CD and works but disk utility doesn't work on it. I slaved it to my laptop and it shows up but then I get an error of failure and then it's de-highlighted.
    Any suggestions is appreciated

    Hi, sounds like the HD is dying.
    I tried booting from CD and works but disk utility doesn't work on it.
    Meaning the HD doesn't show up there, or what?
    I slaved it to my laptop and it shows up but then I get an error of failure and then it's de-highlighted.
    Do you know what the error said exactly?

  • Please help, g5 won't go past grey "start-up" screen

    Apologies if there is a better forum for this question:
    G5 doesn't get past the light grey start-up screen now, and after a while the fans begin to slowly ramp up in speed until they reach maximum. Problems began when in Itunes the machine locked up totally, mouse wouldn't work nor keyboard. I have unplugged power cord and waited various amounts of time, reset the PRAM, and replace the system clock battery.
    Not sure what to do next, Apple Service?
    Thanks in advance!
    Larry

    Problem solved! Luckily this one didn't require a visit to a service center. Here's what worked.
    At power on, launched open firmware (command option o and f)
    ejected disc tray with "eject disc", put in OS X.
    at this point I actually had to re-power up the computer because I then typed "mac-boot" and of course got the same problem.
    On power up, held down C, joy of joys machine booted from disc!
    Opened disk utility and checked my boot volume for errors, tested okay.
    Checked the logs and found unusual "bootsrap....unkown error code".
    figured, well i've gone this far, repaired disc permissions as well, found quite a few permission errors (had been a while since I last repaired).
    Closed disk utility and restarted from boot volume.
    TA-DA!
    At some point, I reset the PMU with a button push on the inside of the machine, which didn't apparently do anything, bacause the machine didn't boot after i did that.
    I also had replaced the system clock battery, which of course didn't fix the problem, but owing to the fact that I had experience several clock type errors previously, I most certainly needed to replace it anyway. Thanks to all who responded, especially Dale for pointing me in the direction of Mac 101 and open firmware.

  • I installed Apple Displays Software 2.1.1, now mac won't get pass grey screen.

    I installed Apple Displays Software 2.1.1 from the disk thinking I was updating my Cinema Display M8149.  After the update I get the grey screen with the scrolling symbol under the apple.  Can anyone help with uninstalling the update?  I don't have time machine activated on my machine and I tried all the resets and that didn't work.

    Ref: Apple Studio Display: Computer starts to Gray Screen after installing Apple Display Software.
    Symptoms
    Do not install Apple Display Software if Mac OS X is already installed on your computer.
    Doing so may cause the computer to start up to a gray screen. 
    Resolution
    Follow these steps if you installed the Apple Display Software included with your display, and are experiencing the symptom described above:
    Start up the computer from your Mac OS X Install CD.
    Reinstall Mac OS X.
    Do not install the Apple Displays Software version 2.1.1 for Mac OS X.
    Verify that the computer starts up correctly ("boots to desktop").
    If the symptom continues, contact Apple.

  • HELP!!! On start up won't get passed grey apple and progress indicator!

    OMG! Someone please help me. Last night, for the first time, my imail froze on me and i was not able to send any emails. After that, the imail crashed and continued to crash after i restarted it. Then this morning the same thing occurred. But this time, the whole computer froze and only the rainbow progress wheel kept was present and it did not let me do anything else. I was not able to open files, click on anything, so the held the power button and turned it off. Now, on startup the computer remains on the grey screen where the grey apple is and there is a progress wheel there that continues to go around. It has been like that since. I tried to turn it on using the safe mode but it won't let me.
    Please help!!!! This computer is less than 2 years old and it is almost finals week and all my files are on here.

    So I followed your instructions, and I got it to boot up using the DVD installation disk. But there was no menu for me to pick the Disc Utility from and I continued on with the installation process to "Select Destination" now it is stuck there and says "Some volues are unavailable until the installer has finished processing" the grey progress wheel keeps going around and it has remained like this for 10 minutes.
    What should I do now? Please help me!

  • 2011 iMac won't get passed loadingscreen

    Hi, i got some trouble with my iMac, i've bought it somewhere in 2011. Now since a month or 2 it won't start up right.
    It's gets on the white screen with the grey apple icon and the loading icon/gif stuck in it for hours. i've tried to boot up from:
    Installation disc
    Safemode
    Verbosemode
    i've used the utility disk to find out if it's a hardware problem and it says everything works normal.
    The installation disc it starts to run than turns down starts to run turns down ... that a few times before ejecting and than it goes back
    to the white loading screen that goes on for hours
    Even in safemode it's stuck in the loading screen.
    I've checked nearly ever topic related to this but didn't really find an answer so can anyone tell me what i can try ?

    it's the original install disc and utility disc for that iMac, yes. that came along in the box.
    I don't know the nummer ( the disc is at my iMac 200km away, i'm staying at my parents house for a week )

  • Mac book pro won't go past grey start up screen

    Went to turn on my Mac book pro 2011 or 2012 and it went to the grey loading screen with an apple, spinning gear and a loading bar. Once the loading bar completes my Mac book just turns off.  It just keeps doing this, I tried to do a safe boot, but once it was done that it turned off and continues to do this circle of grey screen loading than turning off. Please help!

    Hi ANaomi,
    If you are having issues with your MacBook Pro not booting past a grey screen, and/or shutting down during the boot process, you may find the troubleshooting steps outlined in the following articles helpful:

  • Won't boot past grey start up screen.

    All of a sudden my Itunes quit and wouldn't reopen so I thought a restart would be the fix. It turned back on but then got stuck on the grey loading screen. I tried all the hold down button combos and nothing worked. I am out of warranty and am a poor college student. Any advice? Please help.

    Welcome to the Apple discussions.
    You'll need the original OS X discs that came with your system. Insert the first one, and boot holding the C key down, which will boot from the OS X disc. From the menu bar, choose disk utility and repair permissions and repair disk. Any messages on repair disk? If it concludes successfully, reboot. Working now?
    If not, you should run the Apple hardware test. Insert the OS X disc that has 'AHT Version x.x' in small print on the label. Reboot holding the option key down, choose Apple hardware test, click the arrow pointing to the right, and follow directions. If prompted, choose the extended test. Does this give you any messages? Note, if you have either of the TechTool programs, they can do the same testing.
    Post back the results and we can help further from there.

  • Imac won't get past start up screen

    My iMac can't get past the start up screen (white screen with apple logo). How can I get past this?

    The following support article is somewhat outdated. Where it refers to booting from an installation disc, you should boot into Recovery (if running OS X 10.7 or later) by holding down the key combination command-R at the chime. If your startup volume is encrypted with FileVault, you’ll have to unlock it in Disk Utility before you can do anything with it.
    Mac OS X: Gray screen appears during startup

  • My computer won't load pass the grey start up screen

        MacBook pro won't load pass the grey start up screen?

    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
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 3
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 4
    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 5
    Boot in safe mode. Note: If FileVault is enabled on some models, 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 corrupt 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 6
    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 7
    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 8
    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 9
    This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 10
    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. If you can't get to an Apple Store, go to another authorized service provider.
