MacBook not booting up, stuck on blue screen

I just got my MacBook and a friend of mine who is quite experienced with Macs had it for the weekend just to look at and play with... I got it back and it isn't booting up. The grey Apple screen comes up, the little spinning line-circle shows up, then it goes to the blue screen that usually comes before the "Starting up Mac OS X" screen, but it stays blue and the fan spins up and no progress is made and the process cant be broken without force shutting down the computer. If it is necessary to erase the hard drive and reinstall Tiger, I can do that, as my data is backed up... but what would I do?

Try a PRAM reset...

and/or an SMC reset...

Failing this, start up from your Install DVD and run Disc Utility to repair/verify the permissions and the drive itself.

  • MacBook won't start, stuck on blue screen

    My MacBook is stuck on blue screen... forever....
    MacBook info:
    13.3in, 2.0GHz Intel Core2 Duo, 120GB HD, 2X1GB RAM with Leopard
    MacBook was running great until last night...  My screen got frozen while browsing, and force quit did not work.  So I used power button to turned it off.  After that, my MacBook won't boot up anymore...  gray screen for about 3min, apple icon screen for 15min, then stuck on blue screen.
    I think I've tried everything in here..
    http://support.apple.com/kb/TS2570
    The only command that I was able to use was "Reset the NVRAM / PRAM", but no change there...
    I tried install DVD (came with the MacBook), but I cannot boot with DVD with C button and now the install DVD is stuck....
    Is there any way to fix this?  My warranty expired already, and I am trying to do everything before taking this to the store...
    Thank you.

    Thanks Eric.
    I have tried that before, but I gave an another try.  I held the option button longer this time, until I saw the apple icon.  Then cd (DVD?) image came on, so I clicked on it.  But after apple icon went away (10 min?), my macbook is again stuck on blue screen.  I only saw cd image, and did not see any other drives...  Is that a bad sign?
    Thanks,

  • Macbook Pro won't boot. Stuck on blue screen?

    Boy does my Mac have problems, ok here we go!
    Originally, the display on my mac was distorted during operation and when trying to boot up, including in safe mode. Now the distortion is gone (except in safe mode), but when booting up, my Mac either gets stuck on the blue screen or, if it successfully boots up, can't handle anything more than safari without freezing up completely. I have a partition on my hard drive with Windows installed and tried booting up from that, but no luck. I've also gone in as a single user and changed the drive permissions (that worked once, but hasn't since then). I've done a hardware test and that didn't turn anything up. I can't think of anything else to try. Any ideas? I'm stumped.
    Boring details:
    Macbook Pro approx. 3 years old.
    4GB 1600MHz memory
    Approx 100GB free on hard drive
    OS X 10.6.8

    I did that when using singe-user startup. That worked at first but not anymore. I would reinstall the OS, but I'm out of the country and without a disc.

  • Operative system not booting (spinning wheel on blue screen forever)

    Hello,
    I've replaced the standard hard drive of my (late 2009) MBP with a Seagate Momentus XT 750, this is an hybrid ssd hard drive.
    Lately I've seen that the system started to slow down and spotlight started to rebuild its index.
    After the indexing I've decided to reboot  and I've got stuck with a spinning wheel on a blue screen at system startup time.
    I've changed the hard disk and replaced it with the original one that still has the original installation and it works!
    The weird thing is that if I connect the Seagate Momentus to an usb port using an adapter it also works! I can read all its files with no problem, so I tough the problem might be some damaged block in the part of the disk containing the operative system.
    I've launched the Disk Utily app and I've tried to repair the disk and the permissions several times but it still doesn't boot the system.
    Any idea?

  • IMac will not boot. Stuck at white screen after chime.

    I am starting a new thread this because it seems that other people with this problem are able to get their Macs working with some sort of keyboard combination on boot. I am not. Nothing is working. My computer is currently a 27 inch brick... Actually a lamp, since it is frozen on a really nice white screen.....
    Installed Yosemite on my 27" iMac (early 2010, i7) when Yosemite came out a couple weeks ago. Everything was working fine but it wouldn't read my external drive, so I did a reboot. After the reboot, it freezes on the white screen after the chime. No keyboard combinations work to get it to do anything....also, if I hit the power button it shuts off immediately.
    Nothing is working to get it moving. And yes, I am using a usb keyboard, not the Bluetooth, to try to hit any of the keyboard combinations posted in various discussions.
    My AppleCare is expired, so I'm going to be very upset if I have to go pay to have Apple fix their problematic software. Any help you guys can give will be greatly appreciated.
    Thank you,

    See if you can boot into the Safe Mode using your normal account.  Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear and again when you log in. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don’t do them all at once.

  • Macbook doesnt startup, gets stuck at blue screen after langauges deleted

    Hi,
    Got a mackbook pro running Snow Leapard. I was trying to clean up some space by deleting some language files using monolingual. It started deleting english so i cancelled, and when i restarted it has the grey screen with the apple logo then goes to blue with nothing..
    Checking on the net it seems to be the font files. I dont want to just 'reinstall the os'. Surely i can replace the system fonts.
    How can i do so?

  • IBook G4, stuck at blue screen

    Apple ibook G4. OSX 10.4.2
    1.5 GB RAM, 512 on board, 1GB Apple RAM.
    1) Blue screen at login.
    2) Will boot into safe mode and works stable.
    In safe mode, I was able to backup all items cared about.
    After peeling back many layers of testing, including and archive and restore, I arrived at erase and install. So now I have a clean OS. No drive errors, No OS9 install.
    Booted once to login screen.
    Now, boots only to blue screen before login with mouse.
    Safe mode works.
    This configuration was my last 10.4 config:
    Ibook G4 OSX 10.4.2 1.5 GB RAM, 512 on board, 1GB Apple RAM.
    • Fresh from disk install of 10.4.2
    • No Disk errors. Fsck = OK Disk Util from CD no errors, No permission errors.
    • AHT = OK no errors.
    • Will not boot to login, get blue screen and mouse.
    • Will boot to safe mode.
    • Creating second user and setting 2nd user autologin, or ask for login does not fix problem.
    • Neither user password users high ASCII characters.
    • Verbose mode rolls through, stops at same blue screen.
    • Single user mode
    o Time/date is off by one hour.
    o Directory service loads, sees Ethernet link (or fails if disconnected), sees wireless, fails to load initCardWithStoredPrefs (no profile has been configured), AFH is supported. Ntpudate[73]: no servers can be used, exiting System stops and hangs here. Restart boot hangs at starting printing services.
    I currently have this config:
    iBook G4 OSX 10.5.8 1.5GB RAM, 512 on board, 1GB Apple RAM has been removed and reinstalled for testing.
    • Fresh from disk install of 10.5.2 retail copy.
    • No Disk errors. Fsck = OK Disk Util from CD no errors, No permission errors.
    • Will not boot to login, get blue screen and mouse.
    • Will not boot to login, gets stuck at starfield background, no dock
    • Will boot to safe mode and works great and stable.
    So problem is ?hardware?? Where do I go next? I am out of ideas.

    Hi kleach,
    Have you tried using Smart Utility to check your Hard Drive? If not, I would give that a go:
    If your Hard Drive is failing it will let you know. Smart Utility looks at the mechanics of your Hard Drive differently than Disk Utility examines the directory structures. You can download a free trial version.
    http://www.volitans-software.com/smart_utility.php
    After you run the short test, try using the long test and examine the report.
    Good Luck,
    Randy

  • Hi, Hi, Hi  I have the old MacBook Pro. Upgraded to Mountain Lion which completely wrecked the system. So downgraded to Snow Leopard. The updated the combo update. Now stuck on blue screen at start-up. Need help. Greatly appreciated. Thank you.

    Hi,
    I have the old MacBook Pro. Upgraded to Mountain Lion which completely wrecked the system. So downgraded to Snow Leopard.
    Then updated the combo update. Now stuck on blue screen at start-up.
    Need help. Greatly appreciated. Thank you.

    Downgrade Lion/Mountain Lion to Snow Leopard
      1. Boot from your Snow Leopard Installer Disc. After the installer
          loads select your language and click on the Continue
          button. When the menu bar appears select Disk Utility from the
          Utilities menu.
      2. After DU loads select your hard drive (this is the entry with the
          mfgr.'s ID and size) from the left side list. Note the SMART status
          of the drive in DU's status area.  If it does not say "Verified" then
          the drive is failing or has failed and will need replacing.  SMART
          info will not be reported  on external drives. Otherwise, click on
          the Partition tab in the DU main window.
      3. Under the Volume Scheme heading set the number of partitions
          from the drop down menu to one. Set the format type to Mac OS
          Extended (Journaled.) Click on the Options button, set the
          partition scheme to GUID then click on the OK button. Click on
          the Partition button and wait until the process has completed.
      4. Quit DU and return to the installer. Install Snow Leopard.
    This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner.
    If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions.  If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

  • Macbook pro model A1278 wont boot osx stuck at grey screen

    I have had my mbp for about 3 years now and has worked great.  Just today i got home from work and when i opened the macbook which was already running I was in OSX but it was frozen with colored wheel spinning.  I had never experiened this before but I didnt think too much of it and held down the power button to reset it.  Now i am stuck at the grey screen with the Apple Logo and spinning wheel and cant get back into OSX at all.  So i started googling (on another computer obviously) and tried:
    1.  boot in safe mode.  Didnt work, still stuck at grey screen
    2.  boot in safe mode with "commd-shift-v" to see info.  stuck in "dos" looking screen. see pic at bottom.
    3.  tried resetting VRAM w/ "commd-opt-p-r".  did not work, still stuck at grey screen.
    4.  got original OSX install DVD.  Was able to boot to disc and make it to disk utilities.  went to repair and got error "unable to unmount disk"
    5.  ran "repair permissions" and completed that.  ran "verify disk" and got green "disk ok" message.  then re-ran repair and got same "unable to unmount disk"
    so know i am worried.  my main concern is the 80 GB of music I have on this computer (and dont currently have backed-up {que back-up lectures}) and my pictures.  Does it sound possible to recover music and pics based on this little bit of info?  Im willing to take it to the Apple store and pay the price if it sounds like I can recover it.  I am pretty computer savy but am reluctanct to just start trying anything that could lose my music/pics.  I cant try just deleteing and restoring OSX to factory settings and losing all that music/pics.
    so...what is best approach to access and back up these files myself?  I do have another macbook with a firewire connection but am not familiar with that process.  I will get a external HD immediatly (now ofcourse)...can I backup my files from disc utility?
    Thanks for any help.

  • My G4 Apple PowerBook will not boot further than pale blue/grey screen displaying "flashing file symbol / flashing ?"

    My G4 Apple PowerBook will not boot further than pale blue/grey screen displaying "flashing file symbol / flashing ?"
    Last previous action:  Used Firewire cable and "Target Mode" to copy files from G4 eMac to the PowerBook.
    I worked from the eMac to the PowerBook, making the PowerBook the "Target".      Files seemed to transfer OK.     Won't boot from InstallDisc.  Holding down T on startup results in Target mode screen.   I have a G4 iMac and a G4 eMac.    Can I use either of these with Firewire cable to boot-up my PowerBook ?
    I'm new to using this Communities & Forums Help.   Can someone please help me to get going again ! !     Thanks for your time.  Graflood

    Hello,
    It sounds to me like the PowerBook is stuck in target disk mode.
    It's expecting the iMac/eMac to be there when booting. Seeming it's not attached, it will show a flashing folder.
    If your PowerBook internal drive is bootable, then simply hold down the option key when booting and select it's internal hard drive. That should boot your PowerBook into Mac OS X.

  • 10.6.8 update stuck on blue screen... 4 hours and counting

    Upon selecting automatic software update my system seems stuck on blue screen with spinning grey gear.  How long should I tolerate this (going on 4 hours now) before attempting to do something?
    I can access the hard drive of this computer from others on my local network and am able to copy files from it.  I'm wondering if I should try to grab all that is valuable to me before anything worse happens.
    Advise?

    If your data is not backed up copy any important documents you can from your Mac's startup drive.
    Once you are done copying your data, use the power switch to turn off your Mac and disconnect everything except a wired keyboard/mouse and monitor. Start up in safe mode by holding the shift key down right after you hear the startup chime. Keep holding down the shift key until you see the Apple Logo and spinning gear.
    Mac OS X: Starting up in Safe Mode Mac
    OS X: What is Safe Boot, Safe Mode?
    Safe mode will do some maintenance routines and checks/repairs the disk if needed so it will take quite a lot longer than normal to boot. Once your Mac boots restart normally. It will take a little longer than normal to boot but not as long as booting in safe mode.
    If things don't work as expected install the Mac OS X 10.6.8 Update Combo

  • 10.5.3 won't install... stuck in blue screen loop

    I chose to install it from software update. It told me to restart. I did.
    I got hung up on a blue screen loop.
    But no error messages or anything.
    I had to hard reset.
    Then started up fine- but system profiler shows I'm still 10.5.2.
    And software update still shows the update as "downloaded".
    If I click "install" it immediately asks me to reboot, and sticks in the blue screen loop again.
    I have done this three times now.
    If I choose restart from the apple menu- same thing.
    So I decided to shut down- can't shut down. Get stuck in the looping blue screen.
    So it seems like something is gumming up the shut down process. I've heard of startup items making things freeze- can the same thing happen when shutting down?
    Not sure what the issue is.
    The other people posting problems seem to be getting error messages, etc.
    I am going to try to repair permissions, and if that doesn't work maybe I'll try the standalone installer- but why is this happening? this is like a 2 week old MBA with next-to-no third party stuff installed on it... what could be corrupted already?
    fortunately I have backups if worse comes to worse...
    Any other tips/thoughts?
    Thanks!

    Alexroet wrote:

    You could try, it's been known to sort system issues because it's fuller than the incremental "delta" update, so it should overwrite any files that are damaged or missing.
    Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
    But if you can't boot into Safe Mode something is amiss*. Since, you are able to use your system (not stuck on blue screen, try this first:
    Go to System Preferences >> Accounts >> Login Items and remove them. Boot normally and test. If not go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving ~(yourHome)/Library/Fonts to your desktop and restarting.
    *EDIT: You do have to hold the shift key for Safe Boot until you see the spinning gear, just in case you didn't do that.

  • GE60 0NC-622UK laptop is stuck on Blue Screen can't login! please help..

    Had this laptop for just one month, before it's all good. Windows 8 64bit.
    In last two days, the mouse and touchpad became dysfunctional occasionally, able to move the pointer but just could't click on anything regardless of left or right, e.g. choose or open new. It would be working after logoff/relogin and reboot, but same problem still came up randomly.
    Last night, I did the same thing to reboot the laptop after had the pointer dysfunction, but then it displayed a blue screen before the login with a error called 'System Thread Exception Not Handled', and then just stayed on this page would't reboot automatically (waited for 30 mins), so it left me no choice to shut it down by pressing power on/off button manually, afterwards with couple of times rebooting, it just kept going into this same blue screen and could't get into the system...Sometimes it would automatically start diagnosing before blue screen, ask me to restore or repair, but none of them fixed the problem, repeatedly stuck on blue screen every time...
    And I don't have any windows 8 dvd, delivered box only has one for drivers and manual book.. so boot from dvd is not possible..
    p.s. sorry about my english if caused confusion
    thanks..

    Try starting Windows 8 in Safe Mode, its kinda difficult in Windows 8 to do you have to be very precise when doing it, right as the system boots you need to start spamming F8 sometimes you have to do Shift+F8.
    You may want to disable fast boot in the BIOS so you have some time to get ready to hit the buttons, once you get the boot menu up try Start Up Repair first and see if it fixes anything then try booting, if noting then try safe mode and un-do anything you have done to the system recently.
    Let me know how this goes.
    Really appreciated your help!
    I get into troubleshooting page by pressing F3 when laptop was booting up, and changed start up with Safe mode which works..I've done many things in Safe mode, like updated drivers, run anti-virus program, deleted recent installed software, and then somehow the blue screen error was gone after reboot...It seems one of them must be the cause for that problem.
    Anyway, my laptop is working properly now, thanks a lot, if error happens again in future i might still need some help

  • Stuck at blue screen

    It will load up after restart, passing the grey apple logo. When it looks like it's about to finish loading up Mac OSX it gets stuck at blue screen. Tried using Diskwarrior on it but it gets stuck in repair.

    First thing to do in this situation is load the MacOS install disk, and reboot the system holding the C key down when you hear the chime until MacOS shows it is loading. This will not on;y show whether the system is basically sound and capable of booting, but also then give you the opportunity to run Disk Utility (in the Utilities menu of the installer) to check the hard drive for errors, and if any are found, attempt to repair them.
    You'll need a wired USB keyboard (almost any will do, but NOT the Apple aluminium model) to boot to the installer.
    When Disk Utility had finished the Repair Disk task, it if shows no faults, then you have a MacOS problem and likely need to perform an archive and install to set up a new copy of MacOS while preserving your files and applications. If Disk Utility shows errors it cannot repair, particularly reporting 'error on exit', it generally means the drive has suffered a problem. In those situations DiskWarrior is sometimes successful at recovery, though often a reformat is needed. In a small proportion of cases this problem is indicative of hardware failure - usually the hard drive itself, in which case a reformat would generally be expected to fail.
    Be aware of course that reformatting the drive will wipe any and all data, so should not be done unless and until you have secured essential data.
