Mac stuck after start, grey display

after a safari session my mac hung up and does not start again. after the start there is the grey display with the apple sign - so far so good. after that, when usually the display changes to the desktop background the display is bright grey and nothing else happens!!!!!  tried several key-combinations on start as "c" "v" "s" etc. (note i only have a blutouth keyboard) and a start from snow leopard-DVD - nothing!
any suggestions?

    Right after starting up display goes blank and shuts down?
    Any ideas I can't get it started. Thought I would ask for help before making a genius appt.

    Thanks that was very helpful info. I was able to boot into the recovery disk partition and run some basic HD tests and it found no issues.  Then I booted into the hardware test and it found no issues. After these tests it still failed to boot into Mavericks. I'm guessing its a software issue and I can not find the original computer disk. I have a time machine backup from 2 months ago and I could use the disk utility on the recovery sector to launch it but I want to wait and see if I can boot from a software DVD first. If I can repair the current OS that is my best option.
    Thanks.

  • Need help with mac stuck in start up

    I was only able to boot in safe mode. I reinstalled os x 10.4 and it rebooted fine. On doing all the updates on the 3rd reboot it is stuck in a blue screen recycle after the mac os x start up screen. Windows starts okay. The extra problem I have is the internal d drive does not work and I use an external dvd drive. Would appreciate any help. I have flashed the pram. I think it might be related to the last updates.

    What happens if you run fsck?
    Run fsck.
    1. Reboot/Startup holding your Command-S key down.
    2. At the command line type the following and hit 'Return.'
    /sbin/fsck -fy
    3. If it finds a problem and repairs it, immediately run fsck again until the drive checks OK.
    4. After it has check/repaired your disk, type 'reboot' and hit 'Return' again.

  • Mac stuck on the grey apple screen startup? Follow these steps to re-boot....

    So today I had a little scare with my Macbook. It was stuck on the grey apple startup screen with the loading icon. Switching it on and off did nothing and neither did waiting. I did a lot of browsing to try and find a solution but all the forums ended in 'looks like thats the end of my mac' or 'I think i've lost everything' or 're-install Os' blah blah etc. I DID NOT WANT TO LOSE ANYTHING!!! and I'm guessing neither do you! Ok so enough talking, in the end I found a solution which worked perfectly for me and I did not lose anything!!!!!:
    Step 1
    If the Mac is on switch it off.
    Once it is off, switch it on again but this time as soon as you press the power button to switch it on, hold down the Apple cmd key + S.
    Hold this down untill the 'safe boot' screen appears.
    A black screen with white writing should now come up.
    Step 2
    Once the screen has loaded, at the bottom type:
    /sbin/mount -uw /
    [press enter]
    then type:
    chmod 775 /
    [press enter]
    then type:
    exit
    this re-boots the mac. As soon as you have done this the mac should load up again as normal!! Voila!!!  
    Hope it helps!

    Someone suggested this to be risky. worked for me but DON'T DO IT WITHOUT RESEARCHING FIRST and if in doubt CALL APPLE!!!!!

    Mac OS X: Gray screen appears during startup

  • Mac won't start grey screen appearing

    My power mac g5 that is running leopard wont boot up.
    Everytime I try to start it, shows a grey screen telling me to restart the computer (appearing in english, french, spanish, and chineese i think). I accidentaly deleted a folder on the root menu of the HDD entitled "usr". How can i fix this.

    I tried this but it didn't work. I think it is my keyboard because even when I turn the computer on the green led on the caps lock button doesn't light up. I even tried a regular USB keyboard and I had the same result.
    I guess I will have to find my leopard CD.
    Is it possible to just restore system settings from the leopard cd so that I don't lose all my data?

  • I-Mac stuck in start up

    Please help. English major, Apple newbie.
    My imac (intel, G-4), gets as far as the white screen with the Apple and countdown clock, but never actually starts up.
    It's a family computer. I was in one user account w/ admin privileges, had just downloaded most recent updates (itunes and something else). Had been loading a disc in Itunes at same time. When download was complete needed to restart but another user had stuff open, so tried to log out user to close down other person's work in order to restart safely and imac screen went skyblue and stayed that way.
    So, I turned off the power, waited, turned on power..came right on, but never fully restarted..got only as far as white screen.
    So tried both suggestions for powering problems from manual, restart holding option key. Got the hardware icon as manual suggested, clicked on it. nothing. double-clicked on it, got the white screen.
    Turned off power, disconnected power cord. REconnected, and tried again. Same thing.
    So then tried powering on with apple, option, p & r held down, got the second reset music, but then....hello again white screen.
    I've been staring at the white screen in dismay for twenty minutes now.
    Anything else I can do? (Besides visit the rude Genius at the Memphis store?)

    Welcome to the Apple Discussions!
    Unfortunately, your actions may have seriously messed up your Mac. From your description you appear to have done a hard shut down while the Mac was updating the Mac Operating System.
    I suggest restarting from the Restore DVD that came with the Mac to see if the damage can be repaired. Start your Mac and immediately slip in the DVD and press and hold the "C" key. When you get to the Installer select your language. Then from the Utilities menu select Disk Utility. In DU select your startup volume in the list in the left hand pane and press the Repair Disk button in the right hand First Aid pane. Hopefully DU can repair the startup volume. If not you may need to reinstall the Operating System, Mac OS X.
    If you need to reinstall Mac OS X, try to do an Archive & Install to preserve the User Accounts and everyone's data. If you cannot do an A&I, all data would be lost and the hard drive would need to be erased and then install Mac OS X.
    You can see from this experience that updating/upgrading the Operating System, if done haphazardly, can result in grief. You should always close all other user accounts on the Mac before doing a Software Update. It is best to not do other operations simultaneously with the Software Update, like surfing the net or ripping CDs. Stop all other operations and let the Mac's resources be devoted to the update/upgrade.
    Lastly, your Mac is not a G4 or a G5, Apple no longer makes those models. You have an iMac Core 2 Duo.

  • Mac stuck at start up screen

    Mac notebook comes on as normal but stops at load screen. What should I do next. I have tried turning it off and restarting.

    Unplug everything except power. Certain peripherals cause this. Return it!

  • Mac Pro display remains black after start up.

    My 2008 Mac Pro display remains black after start up.  It is plugged in properly and the light comes on, but the screen stays black.  It first started doing this about a week ago, but after a manual restart or two, it would start up properly with the display working.  Today the display has remained black every time I've tried to start up.  Any suggestions for troubleshooting would be greatly appreciated! Thanks!  

    Safe Mode uses a very simple way of talking to the screen -- it does not even load the screen driver, and it uses a very common low resolution.
    If it does not work that way, it simply does not work. You need a replacement graphics card.

    RhysWills1,
    which model MacBook Pro do you have, and which version of OS X is installed on it?

  • Mac stuck at grey screen after rebooting to install windows 7

    My mac refuses to start installing Windows 7 from a disc after I finish going through the "Install Windows 7" option of Bootcamp assistant. I have not got any special devices plugged in during the reboot, just a screen. What do I do with the Drivers on the flashdrive? Please someone help me.

    Which specific model of iMac do you have? If the installer refused to install, then there must be a reason, such as lack of hard disk space, RAM, etc.
    Did you eject the DVD, or is it still in the optical drive? If it's still in the drive, you should try booting from it by turning on the iMac and holding down the 'C' key until you see the spinning radian and see if it will boot from the DVD.
    Post back with more info and results.

  • My 2009 iMac gets stuck on the grey Apple logo when booting up.  It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple log

    My late 2009 27" iMac gets stuck on the grey Apple logo when booting up.  It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple logo again.  This could possibly be an HD failure, but then why does Safe Mode still work and the USB install not work?  Any ideas?

    1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
    Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
    2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
    There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
    Here's a summary of what you need to do, if you choose to proceed:
    ☞ Copy a line of text in this window to the Clipboard.
    ☞ Paste into the window of another application.
    ☞ Wait for the test to run. It usually takes a few minutes.
    ☞ Paste the results, which will have been copied automatically, back into a reply on this page.
    The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
    4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
    5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
    6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    7. Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
    8. If you see an error message in the Terminal window such as "syntax error," enter
    exec bash
    and press return. Then paste the script again.
    9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
    If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
    10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
    [Process completed]
    to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
    11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
    At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
    If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
    12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
    Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

  • Mac Pro gets stuck on the grey screen and won't finish booting

    I have a Mac Pro 1, 1 recently (successfully) upgraded to snow leopard that gets stuck on the grey screen with the spinning rainbow cursor (after the apple logo and brief blue screen) and won't finish booting up. This happened after my computer froze up and I had to force quit.  I checked out the forums and I tried all the all the suggestions (like disconnecting peripherals) and appropriate disk utilities, saw no errors with the HD reported, and had no trouble doing a safe boot  (everything works o.k. there) or starting up from the software disk to perform the repairs.  I did notice that during the repair permissions command, it gets stuck in the last few minutes, the CD starts to chug along, and everything freezes and I have to force quit.  This happens every time I try it.  I eventually backed everything up, erased the HD and reinstalled the OS, reset PRAM and NVRAM, but I'm still getting the grey screen on restart.  Tech tool deluxe reports a "fail" on the video RAM, but everything else seems to check out.  Could it be a graphics card issue?   I did notice some funky visual glitches occurring prior to the breakdown.  Any other ideas?

    I wouldn't trust Apple Disk Utility to do a hard drive repair, but I would go with TechTool Pro 5/6 if you have that instead of Disk Warrior from Alsoft.
    Clone the drive, though you should have some bootable backup clones already; repair the clone; then boot and work from that drive. Always have a working copy of the system.
    And off load all your data to other drives.

  • After updating the software Mac won't Start!!! Plz help.

    Hi last week I brought MacBook Pro 17" Lion 10.7.3, 2.4 ghz Intel core i7, 4gb Ram.
    I updated its software before going for work in countryside. But now when I restart it stops on grey screen with apple logo after the blue screen.
    I can mov the cursor but I login window doesn't comes up...
    I didn't brought my Back up Drive to boot with....
    I went through the discussions on my iphone and have tried doing all this ..
    1. Went into safe mode and into disk utility and have verified disk and repaired disk.
       Have also done verifying and repairing disk permissions. It goes all good but still when I restart it gets
       Stuck on that grey screen with no login space.
    2. Have also tried going into single user mode and tried doing those steps about Fsck
    But only first time it says file modified and after that I tried it again and everytime it says disk is ok.
    And then restarted it but again gets stuck.
    3. Have also tried going into terminal in utilities and putting the commands that Kappy has tried to explain to someone through sudo chow.
    And restart it but then also gets stuck on grey screen.
    4. I tried locating /System/Library for editing the start up items but can't find that.
    I will go back to main city in 2 weeks. Till then I can only start in safe mode. Any suggestion plz.

    Restart and hold down the command-r keys so the Mac boots to the Lion Recovery disk. Select Disk Utility and then run Repair Disk.
