Kernel panick upon startup blue screen

Hey everybody, new to the forum, hoping you all can help me out. I'm using a 15" macbook pro and every time I start it up, I get past the grey apple screen, but as soon as it gets to the blue screen and my mouse appears, I get a kernel panick. This happens every time it starts up. I can use boot camp and boot up in windows, but I am unable to use the OS X side of my hard drive. HELP!

Hi sig,
and thanks for the link.
I failed to mention earlier that when i try to start in safe mode, it does the same, first gray logo with spinning circle, and then blue screen.
On repeat, I have a MAC OS X installation disk, which allows me to use the utilities, but doesnt get verified at the end of the installation process.
is the backup and fresh install the only solution left since all listed on that page has already been used? thanks again.
Madi

  • Extremely Slow Startup, Blue Screen, and Poor Performance

    Hello,
    A couple of weeks ago my MBP 15" (late 2009 model) started performing really poorly. The colour wheel would spin for about 2 minutes if a launched any applications and everything was really slow. It also took about 10 minutes on the grey apple screen to startup and then another 10 or so on the blue screen before slowly revealiing my desktop.
    I took it into the genius bar and the said it might be a corrupt file on the HD. Backed up my HD, zeroed the drive and reinstalled OS. Still the same problems. Ran disk utility several times and got various errors pertaining to HD or RAM.
    Took it back into the Genius bar and they ran a long diagnostic on it, came back to me and said it is deifinatly the RAM. I replaced the ram, (2x2GB ddr3-1066 sodimm) and cleared PRam. Still the same startup and performance issues.
    Any ideas would be appreciated as this is stressing me out big time as I dont know what else it could be?

    Hmm... before this I think I would have restarted the computer in Safe Boot mode which deletes the dynamic-loader shared cache.
    Not sure if it is relevant at this point
    Safe Boot
    # it forces a directory check of the startup volume.
    # It loads only required kernel extensions (some of the items in /System/Library/Extensions).
    # In Mac OS X v10.3.9 or earlier, Safe Mode runs only Apple-installed startup items (such items may be installed either in /Library/StartupItems or in /System/Library/StartupItems; these are different than user-selected account login items).
    # It disables all fonts other than those in /System/Library/Fonts (Mac OS X v10.4 or later).
    # It moves to the Trash all font caches normally stored in /Library/Caches/com.apple.ATS/(uid)/ , where (uid) is a user ID number such as 501 (Mac OS X v10.4 or later).
    # It disables all startup items and login items (Mac OS X v10.4 or later).
    # Mac OS X v10.5.6 or later: A Safe Boot deletes the dynamic loader shared cache at (/var/db/dyld/). A cache with issues may cause a blue screen on startup, particularly after a Software Update. Restarting normally recreates this cache.

    Did you run the Apple Hardware Test. What is the S.M.A.R.T. status, could be that HD is failing?

  • Startup blue screen - but able to login!

    Please,
    Sometimes,during start up, the screen of my ibook become blue. I thought it was a hang, but I tried to just type "enter" and my "login password". After that, I had log in.
    Is it normal? To those who having experiencing the same problem (blue screen at startup), please, try to do the same procedure and answer if it worked?
    Best wishes,

    What was found on Google:
    ... respawning too fast: disabled for 5 minutes
    What's happening
    You see a message on the console like: "Getty respawning too fast: disabled for 5 minutes". Instead of "Getty" it may display a label (such as: Id "S2") where S2 is the label for the line in /etc/inittab from where from where getty was called.
    When getty starts up, it tries to send a login message to the serial port. But if there is something seriously wrong, getty will be immediately killed. Since the /etc/inittab file line for getty says to "respawn", getty is started again, only to be killed again, etc. Thus getty respawns over and over. But the operating system intervenes and stops this nonsense (for 5 minutes). The following sections show possible causes and fixes.
    Getty line in /etc/inittab file incorrect
    Make sure the the line which calls getty in /etc/inittab is correct. A typo in "ttySx" (or "DTxxxx" for uugetty) or in "getty" may cause this problem.
    No modem control signal
    If the terminal doesn't send the PC a CD signal on one of the pins of the serial port, getty will be killed unless the "local" option has been used with getty. So a quick fix is to just use a "local" option (-L for agetty, "CLOCAL" in /etc/gettydefs for ps_getty).
    Another approach is to determine why CD is not being asserted. In many cases the cable to the terminal simply doesn't have a wire for the CD pin so you must use the "local" option. If there is a wire for the CD pin then there may not be any signal on it until the terminal is powered on. Note that the CD pin signal is sometimes supplied by the DTR pin of the terminal (or the PC) by using jumper wires inside the connector.
    No such serial device
    If the device (such as /dev/ttyS2) is bogus (doesn't physically exist or has been disabled), then getty will be killed. You may use "scanport" (Debian only ??) and/or "setserial" to probe for the device or try another ttyS. Perhaps the device has been disabled in the CMOS. See "Serial-HOWTO".
    No serial support
    Linux provides serial support either by selecting it when compiling the kernel or by loading the serial module: serial.o. This "respawning" error happens if serial support has neither been built into the kernel nor provided by a serial module. You many use the "lsmod" command to see if the serial module is loaded. To see if serial support is built into the kernel, check a kernel configuration file (in /boot, in the source tree, etc.)
    Key shorted
    Another possible cause of getty respawning too rapidly is if a keyboard key is shorted. This gives the same result as if the key was continuously held down. With auto-repeat enabled, this "types" thousands of characters to the login prompt. Look for a screen filled with all the same character (in some cases, with 2 or more different characters).
    You may want to try posting in the Unix Forum (if you haven't already done so).

  • Startup Blue Screen

    I have an external hard disk attached to my MacBook Pro, and I use it as my Time Machine backup. Recently, when I press the power button to start up my Mac, the process will stall at the dreaded "blue screen". This occurs after the grey Apple logo, but before the login screen.
    A bit of investigation revealed that if I unplug my external hard disk (by pulling its Firewire cable), the blue screen disappears immediately and I can proceed to login as normal.
    I've tried using Disk Utilities to verify/repair the external disk, as well as resetting PRAM parameter, to no avail. I've even used Disk Utilities to completely erase the external disk and reformat it as "Mac OS Extended (Journaled)", but the problem persists. The external hard disk is otherwise functioning as normal.
    Can someone please tell me how I can kill this annoying blue screen? Thanks in advance!

    Hi Cameron,
    I would suggest trying a Safe-Boot (Hold down shift after the chime), if that works, then it could possibly be an issue with startup items.
    If it reaches the blue screen, that means that it has loaded the EFI and the kexts etc. SO it doesn't really sound like anything to do with your HardDrive.
    Perhaps take a look at http://support.apple.com/kb/TS1411#symp1.
    Might help you out
    Good luck

  • G3 X4 startup blue screen responsive arrow Darwin login prompt

    I tried booting in 'safe mode,' but the screen goes black and the machine turns completely off. The trouble shooting page on apple.com only gives instructions for 3.9 or earlier.
    Where are the instructions for X.4 when 'safe mode' won't work?
    Starting up normal led to a 10 minute frozen blue screen (with responsive arrow) that ended with a 'Darwin/BSD' prompt for a login. What's up with that?
    Thank you very much if you have any sage advice!
    (this particular machine is a G4 with OSX 4.? [the latest OS])

    Hi, knowmoore.
    You wrote: "I tried booting in 'safe mode,' but the screen goes black and the machine turns completely off."That usually indicates that your startup disk is severely corrupted. See: "Mac OS X 10.4: Computer shuts down during Safe Boot."
    I suggest you begin troubleshooting using the Procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
    Good luck!

  • MacBook Stuck in Startup Blue Screen, HDD is Spinning

    Well, I fear the worst has occurred to my mid 07 Macbook.
    When I boot up the machine, it stays stuck in the blue screen start up, not able to find any startup disc. I gave a listen to the HDD and it is spinning when I try starting up. So this would mean a system failure, however I have had the motherboard replaced twice this year. Is the motherboard/system most liekly the issue?

  • 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?

  • HELP! OS X won't boot - Blue Screen at startup... No mouse, nothing...

    I have a PowerMac G4 MDD running OSX 10.4.8 (or 9)... About a month ago, it suffered a kernel panic, and upon restarting, it wouldn't load OS X. Now whenever I start the computer, it displays the white screen with the Apple logo and the spinning gear, then it switches to a solid blue screen and stays there. There is no mouse on the screen and the keyboard is unresponsive.
    The computer will boot in safe mode. I have tried removing login items in the account preferences and third party items from the StartupItems folders. But still, I get the blue screen.
    I've tried resetting the PRAM. I booted from the install disc and repaired the startup disk. It said no repairs were necessary. I've repaired permissions on the disk as well. I also booted from the Hardware Test disc, but still, nothing.
    Yesterday I did an Archive and Install from my Tiger install disc, hoping that this would fix things, but it didn't. As a last resort, I'm considering wiping the hard drive and doing a fresh install of OS X.
    Does anyone have any advice? Has this happened to you too? Does this sound like a hardware or software problem?
    PowerMac G4 MDD   Mac OS X (10.4.8)  

    Do you have a firewire external drive, or other bootable backup? Try booting from another drive & see if the problem persists. Run Disk Warrior while booted from its CD, or from an alternate drive. I don't think it will help, though, because Archive & Install should create a new directory. If the problem persists when booting from an alternate system, you most likely have a hardware problem. You could install a fresh copy of OS X on your alternate drive to make sure (but not if it's your only backup!).

  • 'Famous' blue screen at startup AND safe mode boot failure

    Dear all,
    Two days ago, after installing the new Java update/airport update and restarting, I encountered a 'blue screen' on startup after getting past the mac symbol and swirling cog. I cannot say whether the updates were the cause (doubtful) of if my cheap USB mouse that was still plugged it caused it or whether i have the dreaded 'bad sectors.' The cause aside, here is what i've tried to fix the issue:
    1) Disk Utility - Verification (OK'd) and Repairs (fine)
    2) Disk Utility - Verification of Permissions (a few needed to be done) All repaired
    -blue screen-
    -Restart after period-
    3) Rebooting in safe mode, removing startup items from the login items settings menu
    4) Removing startup items from System/Library/StartupItems folders
    5) Remove airport extensions (recent - date modified in list view)
    (NB - safe mode i could say my desktop perfectl in original form and all files!)
    -Restart-
    -no longer able to start in safe mode-
    -blue screen remains-
    6)Single User mode -
    resetting preference files (loginwindow.plist and windowserver.plist)
    Finally system profiler from Tiger DVD states:
    *Permissions repaired
    *Dependency errors: com.apple.iokit.IOUSBFamily & com.apple.kernel.iokit no valid version found
    *Integrity: kext has no receipt
    I backed up most my data from the LAST crash, but recent music/1000 photos and others have been backed up altho i've been meaning to! Help!
    I'M PANICKING now can no longer get in SAFE MODE!!
    Please help Mac911!!!!

    G3 iBook 800mhz   Mac OS X (10.4.6)  

    Update:
    So, I managed to do ALL that you said, EXCEPT, the reboot and work fine business.
    I created the admin account which works fine. So now I can see three user accounts (looks like there as already an admin type one).
    The one I created works fine, only, I can only access/see the login screen through a safe boot, (otherwise blue screens...) . I can get into the admin account fine, but when restarting and logging in as my original user account it won't boot. Something is very wrong in MY user account. I think at this point my data there is still retrievable somehow for a backup, clean start. but i haven't reached that point yet.
    Anyone have any clues what migt have caused the error in my user login?
    One of the things I tried (too hastily now i admit) first was to remove the recently added updates from the extensions folder. has this exacerbated the problem? Can i put them back without logging in as me??
    remember from my first post system profiler says software/extensions integrity 'kext has no receipt' and dependency errors: 'com.apple.iokit.IOUSBFamily and com.apple.kernel.iokit; no valid version found' - whereas in my newly created admin account it appears AOK.
    is this the source?
    any ideas anyone?
    sorry lots of queries here but i am ever hopeful.....
    All yours,

  • IMac G5 – Won't startup except in Safe Mode (10.5.5). Otherwise Blue Screen

    I’ve had my iMac (pre-iSight) for about 3 years now and up until recently never had any major problems with it, despite using it for about 12 hours per day, every day.. A couple of minor problems however had developed, but several months ago and didn’t seem to affect the system:
    (1) Software update stopped working (had to download & install updates manually) &
    (2) Couldn’t verify or repair permissions (even pre 10.5.5. Even when I tried to repair them from another startup disk, the message I got was ‘no package receipts’ – although I could see that they were there in the “receipts” library folder)
    A couple of days ago I decided to try and fix the problems by erasing my startup disk (after backing up all my data of course) and re-installing 10.5 from the installation DVD and then bringing the system up to date. At the time I did this I hadn’t upgraded or installed any new software for several weeks.
    For about one day after that it worked fine. The only ‘alarming’ thing that I noticed during that day was that whilst playing a movie the CPU temperature rose to about 89 C. (I use Temperature Monitor). I read somewhere that the CPU temperature should not exceed 85 for this model and that if it did the system would either shutdown or go to sleep, so I was surprised to see it go as high as 89 (assuming that the right temperature was being reported) before it went to sleep. However, even after that it, it started up correctly a couple of times.
    Since then it will only boot in Safe mode, and when it does it carries on working indefinitely without any problems. The only thing that I lose in safe mode which seems odd – in addition to all the things that I know I should lose – is Audio. The preferences panel says: no input, output devices attached (ie not even the ones built-in).
    If I try a normal start up, the system will go through the grey screen, apple logo, spinning ‘cog’ etc and then almost always go to a blue screen where it stays put. There is a black cursor in the top left corner which, when I try to move it, duplicates itself so that I end up with 2 cursors – one which moves and one which stays in the top left corner.
    On very rare occasions (about 1 time in 20) during a normal startup the system will get past the blue screen and to my desktop (in fact this happened several times consecutively before I got to the point where I could only startup in Safe Mode). However, moving the cursor into the menu bar or into the dock would result in the whole screen freezing – the cursor would move, but nothing else would happen). Also I would see that several pixels were ‘missing’ from the desktop. The desktop is normally solid green, but I would see 3 or 4 red and black pixels.
    I’ve studied all the forum topics that even remotely resemble my problem and tried just about everything I can think of including:
    1. Resetting SMU & PRAM (repetitively)
    2. Running the Apple Hardware Test – All tests passed
    3. Replacing the PRAM battery
    4. Check that the fans are working (I can hear them and when I take the back off, both fans spin)
    5. Erased the disk again, installed the OS from the installation DVD, so that there is no third party software on the system. (and then tried a normal boot both with the original 10.5.1 and 10.5.5 after applying the combo update).
    6. I have several external disks with several copies of the OS on various partitions, including a 10.4.11, but trying to boot from any of those ends with the same result. I can only boot in safe mode, other wise I get a blue screen (or very rarely it will squeak through to the desktop & then immediately freeze).
    Always the same result – safe boot only.
    From reading through the various topics, I get the feeling that my problem may be related to the graphics card, but if that is the case I don’t understand why the system will always boot in safe mode and then run without any problems all day. It even allows me to play movies: very jerky (and no sound), both when I move the QT window and the images themselves, but it still plays.
    Any thoughts on what the problem might be (other than fatal) would be greatly appreciated. Or an explanation why, if it is the graphics card, the system will continue working after safe boot.
    I’ve copied out the system details from Profiler that I think are relevant below.

    I had a very similar problem with my 20" iMac G5 ALS running 10.4.11. It began with random freezing inside the OS and intermittent slow booting, but quickly progressed (over a matter of days) to hanging at the blue screen before the logon window, just as you described.
    I too, found that booting in Safe Mode was successful. I ruled out the airport card by manually installing that kernel extension in Safe Mode. A check of the logs pointed to "ATY" which I've since found out is a reference to the ATI drivers, which brought me to this post.
    At least on my system--and I have tested this on Tiger (10.4 and 10.4.11) and Leopard (10.5 and 10.5.6), the only .kext that needs to be removed / renamed is ATIRadeon9700.kext. My preferred method of doing this is to drop to the terminal and type:
    sudo mv /System/Library/Extensions/ATIRadeon.kext /System/Library/Extensions/ATIRadeon.kext.disabled
    This preserves the relevant permissions and ownership, which you'd otherwise have to reset manually if you copy the file elsewhere and then delete the original in the Finder, and then want to restore it to its original condition, BTW:
    sudo chmod -R 755 /System/Library/Extensions/ATIRadeon.kext
    sudo chown -R 0:0 /System/Library/Extensions/ATIRadeon.kext
    Any OS X update will replenish the file, so you should be at the ready to reboot into Safe Mode the first time and rename the file again.
    The downside to all this is that the video acceleration doesn't work, so graphics operations are slow and jerky, but at least everything else seems to be okay, in my case anyway.
    Popping open the case did indeed reveal four bulging capacitors. I bit the bullet and purchased some replacements, part number 647-UHN0J182MPD from Mouser:
    http://mouser.com/Search/ProductDetail.aspx?qs=pjJ%252bhmlZec6zHXGt6EoiHw%3d%3d
    Although I wasn't looking forward to desoldering my logic board, I wasn't real hopeful that I'd have success getting the local Apple shop to replace it under warranty either. I did find some helpful information on performing the fix yourself:
    http://jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php
    And I do want to be able to sell this thing for at least a little cash to help offset the cost of a new quad-core iMac, whenever they're released.
    Fortunately, for me, the service tech at the Genius Bar at the local Apple store agreed to fix it under the power and video extended warranty, even though it was slightly outside of the warranty period, due to the fact that I had brought it in about a year ago and had the power supply replaced under the same warranty.
    I almost didn't bother to bring the machine in because it's a real nasty day here today, and I figured they'd just tell me "That'll be $800 to fix it," and I'd end up doing surgery on the logic board anyway in addition to carrying the thing up and down the steps to my condo. Boy am I glad I did, though. Apple customer service rocks.

  • Blue screen and "startup disc is full" error

    My iPad2 is frozen with an "unaable to download app.....' error and after unsuccessfully trying to turn it off, I attached it to my MacBook Pro to try to sync it.  Nothing happened so i restarted my Macbook Pro.  Upon start up, the MP screen went blue and the error message "Your Startup disk is full" appeared. I hit OK & was left with a blue screen. 
    After disconnecting the ipad2 from the MP and restarting the Mp, same issue appeared.  Turned MP off and started in single user mode (Cmd-S).  Typed 'reboot'. came back up again with blue screen. 
    Tried single user mode again & typed 'fsck -fy'. System ran a checking routine and came back with "**The volume MacIntosh HD appears to be OK".  Entered 'shutdown -r now' to same results - blue screen , start up full -
    Now what?
    Looks like I'm running Mac OS X, 10.6.8

    I understand CS4 does like to use a lot of space for scratch space when making complicated image changes. Verify you are able to control how much scratch space it uses in such functions. If you aren't, maybe it is indicative of needing a separate partition or hard drive to store CS4 temporary drive. When you have a separate partition or hard drive, you can erase the drive, and avoid fragmentation of files larger than 20 MB. Normally Mac OS X doesn't suffer fragmentation, except with large files as explained here*:
