Is the blue screen on start up normal

when I startup my macbook pro that I just got the screen goes gray with the apple logo then right before the screen where I put in my password it goes blue for about 8 seconds.When I shut down my computer the screen goes blue as well.I've never had a mac before so I don't know if the blue screen is normal or not.Should I contact apple support for help or is that a normal thing?

This often happens if the permissions, directory, or hard drive is damaged.  Is your data backed up?  Only then can we safely examine the drive.

  • Can't get past the blue screen with "starting Mac OS X"

    I am having problems with starting my iMac. It gets to the blue screen with "starting Mac OS X" but won't go beyond that point. I was able to get the disc drive open with the help of other posts, holding down the mouse while turning on the computer, but the drive won't stay closed with the install disc in it. I have even tried holding down the "c" key while restarting the computer and it wouldn't work. Any help would be greatly appreciated. So much info that I could really use. Also, please keep in mind that I am not too computer savy. Simple language please.
    Thanks

    If the steps I provided in my earlier post are not helping, then I see your options at this point as follows:
    1. Run the Apple Hardware Test (AHT) that came the affected computer. See my "Apple Hardware Test" FAQ for comprehensive advice on using the AHT in troubleshooting.
    2. Performing an Archive and Install. For important tips on this, see my "General advice on performing an Archive and Install" FAQ. Perform the steps therein in the specified order.
    3. Take the computer in for service. If there is an Apple Retail Store in your area, I'd recommend taking it there. You may wish to call ahead to make an appointment at the Genius Bar.
    Good luck!

  • Mac pro still hangs on the blue screen on start up.

    Hi.
    my mac pro still hangs for ages on the blue screen before the login page where i input my password appears.
    i've tried starting up in command-V and that didn't work.
    i thought snow leopard was meant to improve, it has just slowed my start up down greatly!
    could someone please advise on how to fix this?
    thanks
    Dan.

    Hi boom,
    Have you tried downloading and re-applying the latest Combo update?
    If not, go to the apple download page, find the Combo update (couple of hundred MB) and install it.
    This has fixed various issues in the past for numerous users... it might do the trick for you.
    After it's installed and rebooted, repair permissions and reboot again.
    Also check to see (using software update) if there are no firmware updates available for you.
    And, make sure the OS drive's root is clean, just the basic Applications, Library, System and Users folders, no other mess. If there are 'Previous System' folders from earlier Archive & Install situations you might want to remove those.
    Finally, if you upgraded from a PowerPC to Intel using the Migration Assistant the symptoms you are describing are very common, the migration assistant well... it ***** :/

  • IMac G5 running OS 10.4.11. Started playing with a bluetooth speaker (may or may not be related). Now I cannot get past the blue screen on startup. I can get into safe mode. Tried install disc for disc utility and reloaded OS. Still get blue screen.

    I have an older iMac G5 running OS 10.4.11. The other day I started playing with a bluetooth speaker (may or may not be related). Now I cannot get past the blue screen on startup.
    I can get into safe mode. But no regular startup.
    I tried disabling bluetooth, thinking that might be related. It didn't help.
    I even tried using the install disc to run disc utility. That didn't work so I reloaded the OS.
    But I still get hung on the blue screen when trying a normal startup.
    All help would be appreciated.

    Try resetting the PMU/SMU and PRAM/NVRAM. You'd need to identify the mode of resetting depending on the model of your G5 iMac. The Apple support sites that would help you for this are –

  • Stuck at Blue Screen on start up

    My MacBook Pro gets stuck on the blue screen at start up. Have tried all the obvious fixes but no joy.
    I put my mac in target mode and connected to another MacBook Pro
    Then selected my HDD as the start up disc, rebooted, and this worked fine, i was able to run my HDD and all software fine.
    I conclude this shows i have a hardware problem on my mac.
    Can anyone please give me a clue as to what it might be? or is it time for a visit to the apple store (and a remortgage on the house)?
    Many thanks Phil.

    I know you already mentioned that you "Tried all the obvious fixes" but this is the first thing that came to mind when I read your problem.
    Hold down the power button until your Macintosh shuts off.
    Then hold down the power button until the white light on the front of your Macintosh starts flashing rapidly.
    Then release the button and see if your device boots up normally.
    I had this very same problem happen to me a few weeks ago and I was able to solve it by doing those few steps.
    Hope this helps!

  • On start up sometimes I get a blue screen and start up hang there

    On start up I sometimes get a blue screen and it hangs there the only way to get out of this is to turn the iMac off at the back then when you turn it back on the desk top appears without going through the startup screens. Even had the blue screen when starting in safe mode.

    Then run Apple Hardware Test in Extended Mode, it's possible you have a hardware issue. If you still can't locate the issue the next step is taking the machine in for a professional diagnosis at your local Apple Store or AASP.

  • I have a PB G4 that won't start. It shows the gray apple screen, shows the blue screen, and then the screen goes black, and "sleep" light pulses.

    I have a PB G4 that won't start. It shows the gray apple screen, shows the blue screen, and then goes black. The sleep light pulses. From there, I can't turn it off normally. I have tried restarting the PMU. And I have tried unplugging the ac adaptor and removing the battery. From there I have plugged only the ac adaptor in, and it will begin to start but do the same thing once it shows the blue screen.
    I tried only using the battery (without plugging in the ac adaptor) and the same thing happens. I tried starting the computer while holding down CTRL, Option, P, and R, waiting to hear the start up chimes 3 times, and then holding Shift as it starts up. But I still get the black screen once I see the blue one, and the computer's sleep light pulses.
    I need something very important from this computer. And was able to start it last night. I did not shut down the computer, and was going to take it to a friends to use his printer today. The computer was in sleep mode in the morning.
    Thanks for any help!
    Gina

    What your describing could be a logic board or memory issue. 
    You did or did not hear 3 startup chimes?  If you hear 3 chimes when you start it, that would indicate a memory problem.  Try reseating the memory to see if that makes a difference. If you have 2 RAM cards, try one then the other in each slot. If you have 1 RAM card, move it to the other slot. Powerbooks can develop one bad slot.
    You may need to pull the hard drive out of the Powerbook, put it into an external case, then read it from another mac.

  • IMac makes a loud beep on start up, won't load past the blue screen and the black ticking dial appears every few seconds in centre of screen.

    Urgent help!
    Out of the blue my mac lost the mouse cursor even though it had connection so I rebooted only for the mac to make a loud beep on start up then get stuck at the blue loading screen. It won't load past the blue screen. I've tried to reboot holding down the shift key but no change. I've also shut down, unplugged the main for 15 seconds, re plug and wait 5 seconds before starting up again but no change. Does anyone have any suggestions?
    PS: I'm not too sure which systems I am running without being able to check in about this mac. I bought my imac in January or February 2011 if that helps.

    The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
    If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
    1 beep = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
    5 beeps = processor is not usable

  • Can't Start Up: staying in the blue screen for 8 hours...

    HELP!!!!
    My powerbook G4 can't start up
    All goes well during StartUp untill it gets to a Blue Screen
    then it stays there
    its been 8 hours so far...
    ( i can see the mouse pointer )
    This is my 3rd try -- but every time it just stuck in the blue screen stage
    Please help.

    First, I'd review the troubleshooting procedures on this page:
    http://www.apple.com/support/powerbook/
    Other things to try: remove the main battery and let the PB sit with the A/C adaptor connected for several hours. This will make sure the backup battery has some charge assuming it's not completely dead.
    Then try starting the computer with the SHIFT key depressed ("Safe mode"). This does some directory repair. If you get a desktop via a safe boot, do not try to use the computer just yet. Do a normal restart, then see if it is usable.
    If you have your system disks or the disks you used to install Tiger, dee if the computer will boot from them by holding the "C" key during boot.
    How full is you hard drive? You need a minimum of 15 percent free space for the OS to work with any efficiency.
    Because there are several variants of the 17" G4 PowerBook, it would be helpful to people here if you would add the processor speed to your equipment line. Showing how much RAM you have is also useful. That way you can get help faster because people don't have to ask first.

  • I book wont start up past the blue screen

    I have a similar problem. Not sure you're on here (since the post is really old) but did you manage to work it out? How?
    My thread:
    https://discussions.apple.com/message/19007548#19007548
    My Imac froze earlier today as I was dragging an image from safari into indesig and when it froze the weirdest pattern overlaid the screen. It looked just like the opacity pattern from photoshop with grey and white squares. I turned the computer off using the power button and unplugged everything.
    Now when I try to start it these weird lines appear on my start up screen (see link)...
    http://meijerladdaruppgrejer.wordpress.com/2012/07/24/oops/
    as you can see the apple and the wheel appears as normal...
    ... then it moves to a normal looking white screen (perhaps a bit greener than usual) and around 30 seconds later freezes at the blue screen.
    I've tried the cmd + alt + p + r several times but it won't help.
    If i press alt during start up I can see and choose my hard drive but just end up at the blue screen again.
    Can I try starting it up in safe mode or something?

  • Blue screen on start up.  The wheel spin and the blue screen gets brighter for a second, then the blue screen dims and it repeats with the wheel.

    When I start up my imac, I get a blue screen.  The wheel spin and the screen gets brighter for a second, then the blue screen dims and it repeats with the wheel.

    Are you referring to the startup screen which is normally gray with the dark gray Apple logo or are you referring the login screen which is typically blue? If it's the latter you might give this a try:
    Clearing Caches to Fix Login Problem
    You will need to type some Unix commands. If you are not comfortable with this, I don't know of anything other than a re-install. But if you are careful, you should be OK. I recommend you print this out in a largish mono-spaced font so you don't miss any spaces (or add extra ones). Note that case is important.
    Be careful. Some of these commands are dangerous, since you are going to be root.
    Start up in Single-user Mode. When this has finished you will see a prompt ending in '#', although there may be other messages. Enter the following commands after the prompt:
    /sbin/fsck -fy
    Press RETURN. Wait a few seconds for 8-10 lines of output. If the last line says repairs were carried out, repeat this command until you get a message 'The volume <yourdiskname> appears to be OK'. Then continue with:
    /sbin/mount -uw /
    cd /Library/Preferences
    rm com.apple.loginwindow.plist
    rm com.apple.windowserver.plist
    cd /Library/Caches
    rm -r *
    cd /System/Library
    cd /System/Library/Caches
    rm -r *
    reboot
    Press RETURN after each command.
    This should now take you to a proper login screen after the normal boot sequence. You should then Repair Permissions by using Disk Utility (in your /Applications/Utilities folder).
    If it's the former then reinstall OS X. For Snow Leopard:
    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

  • I have a MacBook Pro, it recently started freezing upon startup. It would get to a blue screen and just sit there. I've tried booting in safemode to run disk repair and still doesnt help. If I do manage to get past the blue screen, it still freezes

    My mac keeps freezing upon startup. It will get to the blue screen and promptly freeze. If I manage to get past the blue screen, and open up youtube on google chrome, it will freeze before it loads youtube. I've tried safeboot and disk repair, nothing seems to work. I even tried to factory reset it but it wont connect to my internet when I reboot with power + option.. any ideas?

    This can be used to boot the machine and delelte enough files to get it to boot normally.
    .Create a data recovery/undelete external boot drive
    Read about storage drive so you can store your extra stuff.

  • Upon start up I get a start up disk full message and to delete files, now I only get a a blue screen on start up. How to I get past the blue screen and how do I delete files?

    Upon start up I get a "start up disk full message, delete files". Now on startup I only get a blue screen. How do I get past the blue screen and how do I delete files.

    That;s really not enough free space... you can use a tools such as OmniDiskSweeper to find out where your large files reside and begin pruning (or copying to an external if they're files that you want to keep).
    One thing is certain - if you're going to continue your current usage you're certainly going to need to install a larger boot drive.
