Blue screen at booting

Hi, newbie to Mac here, still trying to figure out my way around..
Yesterday I received my Macbook after the set up I downloaded some updates and firefox, stuffit, windows media player...
then I noticed after restart , after the grey screen with the apple logo I get a blue screen for about 10-12 seconds, then the laptop boots normally... is this normal to have this blue screen? I don't remember seen it the first time I turned on the laptop

Hi borderline-
That's how it looks on my Power Mac.
It is different than OSX 10.4 and a little disconcerting at first

I am getting frequent lock-ups and blue screens during boot up. The lock ups occur during normal use and I cannot click anything or force quit. The cursor shows something is loading, but never stops. I have to use power button. Ideas?

Blue screen on boot up

I am having issues with my 13.3" MBP, blue screen on boot up?, cannot figure out why? If I log in as another user(from my older macbook) it will boot but I cannot get to my newer files and docs. Any thoughts?, it appears to be a permission issue as if I boot up as a target disk using firewire, the files I want to access are still on my hard drive.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
*Note: If FileVault is enabled under Mac OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.
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.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

X200 with OCZ ssd blue screens when booting from docking station

The x200 blue screens when booting from the docking station. If I take the laptop out of the docking station to boot and then dock once booted the laptop is fine.
The issue started happening when you I upgraded the laptop form xp to windows 7 and installed an OCZ vertex 2 solid state drive.
I have tried updating the firmware on the ssd using this utility
http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-69806
The program showed that my ssd was running firmware version 1.29 and did not need to be updated.
I have also tried updating the x200 to the latest BIOS. Nothing seems to work.
Any ideas or suggestions are greatly appreciated.

HELP! iMac G5 hangs at blue screen, but boots in Safe Mode

Please can anyone guide me to recover my iMac G5 PowerMac 8,2 running OS X 10.4.11.
Problem; Mac hangs on start-up at blue screen after grey Apple screen. Mouse pointer eventually appears but that is all.
Actions taken so far without success:
1. Disconnected the printer and rebooted - no success.
2. Booted in Safe Mode - first time the screen was completely scrambled but with safe mode log on screen showing through.
2.1 Rebooted in Safe Mode OK This has not occurred again and I have entered Safe Mode twice more without problems. But worrying!
2.2 In Safe Mode I ran disk Utility and verified and repaired Permissions, mostly old EpsonPrinter files.
2.3 I also verified the Disk, which was reported OK.
2.4 I was able to save critical documents to USB............ Phew!
2.5 Reboot in Normal Mode - no success
3. Reset PRAM
3.1 Reboot in Normal Mode - no success
4. Reboot in Safe mode - works fine. NOTE: time and date appear to be correct and dont need resetting.
4.1 Run Disk Utility again and Verify Permissions - OK. Nothing needed fixing.
4.2 Run Disk Verify - Passed OK
4.3 Reboot in Normal Mode - no success. Hangs at blue screen with mouse pointer visible and working. Then pointer vanishes.
I would be most grateful for your help in moving this forward

Got to figure out which which of the things dropped when you boot in safe mode is causing the problem.

Qosimio G30-116 with blue screen on boot

I have a Qosmio dule boot Qosmio G30-116, booting in windows generates a blue screen of death, which is quickly cleared before I can read what is displayed.
Boot it in windows safe mode results in a long list of files being displayed the last one being Mup.sys
Booting the machine in Linux and running everything that I can think off does not generate an error.
Running the on board Toshiba dignostics from the BIOS does not generate an error.
Running the linux memory check does not generate an error.
Viewing the file system does not generate an error.
So I don't think I have a hardware problem, I think something is matter with windows
Does anybody have any idea how to stop my clearing the screen so I can actual find out what the problem is ?
There is a lot of valuable software on this machine, I have no desire to trash the entire disk to attempt to repair what seems to be a specfic windows problem.

Hi,
I am sure its not a hardware problem. Its a pure windows related problem but its like one of these bluescreens which try to tell you that your memory is gone. :(
First of all, try to remember which software youve recently installed. Which drivers were updated and how many microsoft KBs were automatically installed.
I would really recommend you to google for "Mup.sys" and check the site "hardwareanalysis" which is the second entry when searching for that term.
This problem has many reasons and there are many different solutions..because the reasons are so different. So, if you want to keep your "valuable" programs and dont want to reinstall your system (what could be btw. the easiest way after backing up your "valuable" software) then check the forum Ive suggested and you will find hopefully the enlightment.

Blue screen when booting from USB drive in UEFI mode (2013.07)

SOLUTION for me was to update the firmware on my ASRock mb as thatu pdate changed the EFI software (by American Megatrends) version from 2.00 to 2.31. However, other users are still experiencing the blue screen.
SHORT VERSION
When I try to boot Arch Linux 2013.07 with an USB drive in UEFI mode (for installation), I get a blue screen (which is rather a literal description and not a hint towards the old Windows' one) with the message
Failed to install override security policy (14): Not found
LONG VERSION
I made an USB installation media (product: Intenso Rainbow) by following this advice on the wiki.
I used the july release of Arch for that. First of, after installing the image to the USB stick I found that I needed to correct the label in the archiso-x86_64.conf file to ARCH_201307 (or was it the label of the usb stick, can't remember right now). (Pretty sure it was the same problem with "Linux Live USB Creator" which I used 3-4 months ago...)
After doing that, I rebooted and selected the entry
UEFI Intenso Rainbow
from this list of entries:
SATA HDJ ... something (the hard drive where Win 7 64 bit is installed with all programs)
SATA something (hard drive which only contains data)
Windows Boot Manager
USB: Intenso Rainbow
UEFI: Intenso Rainbow
It went to a blue screen with a message in white text saying
Failed to install override security policy (14): Not found
Below that was an OK button which had a black rectangle over it.
After I experienced the bluescreen, I tried booting the
USB Intenso Rainbow
entry and the boot process then worked fine, I got to that Arch menu where I could choose
Boot Arch Linux (x86_64)
Boot Arch Linux (i686)
Boot existing OS
Run Memtest...
and so on...
But just to make sure, I then did the check for UEFI mode according to this and only saw a folder acpi and ... something else I can't really remember, but it definitely was not efi. Thing is, I needwant to boot into UEFI mode as I have Win 7 already installed in UEFI mode.
Some info about my motherboard: it's from ASRock and is called H67M. The BIOS is dated to 2011-10-26 and is version 1.7.
So far, I only found a mention of the problem here at superuser.com.

Ok then, so this thread has also become about the blank screen problem when booting (in this particular case, Arch 2013.06 since 2013.07 seems to be worse).
srs5694 wrote:Typically, you adjust kernel boot options using your boot manager or boot loader. In GRUB, you hit the "e" key to open an editor. In rEFInd, you hit F2 or Insert twice. I don't recall offhand what key does the job for gummiboot (which I'm pretty sure the Arch installer uses), but I'm certain it's got the feature.
You are right. Thanks. I realized I had the gummiboot config right in front of me all the time. It's the file 'archiso-x86_64.conf' in \loader\entries (on Windows).
An addendum: I think the USB: Intenso Rainbow boot option takes me into a GRUB menu. Hitting 'e' in this "big" and fully designed menu didn't do anything IIRC. Hitting 'Tab' did the trick to get into editing the boot command line.
Hitting 'e' worked in the gummiboot menu though.
So I tried booting with the following options (also by combining some of them)
nomodeset
acpi_backlight=vendor
radeon.modeset=0 (I have a Gigabyte 7870 card in this desktop machien)
i915.modeset=0
but it did not help.
To be rather safe than sorry: I should mention that there are two grey-ish bars visible on the top and bottom of the screen after I try to boot the first entry, Arch Linux archiso x86_64 UEFI USB. Always has been with those two older Arch version (2013.05+2013.06). I also found another thread where one user talks about using the VGA port of the monitor, which I am currently not, I am using the DVI one, so that's worth a try too. EDIT It did not help either. What I did was setting the primary graphics adapter in the UEFI north bridge configuration menu to 'onboard' which worked immediately when rebooting (I hit the button labeled "Source" on my monitor and it showed it is using the "Analog" mode), but the problem just stayed the same. Adding aforementioned boot options or a combination thereof did not change anything.
Thanks for the e-mail addresses, I sent one to James Bottomley.

Macbook will not boot. Locked hard drive. Blue screen when booting

Hi, my little brother decided he wanted a few files off of my mac book, so he went to settings>sharing>file sharing and added my only hard drive to the list and tried removing everyone but his name and password thinking it would only effect people trying to log into my hard drive, not actually me on my computer alone trying to boot mac osx from it.
He came crying to me telling me he paniced because he saw a locked icon on my hard drive and couldn't do anything, so tried to restart the macbook and now i just get a blue screen and nothing happens when i try booting it.
Right now i'm thinking i gotta archive and reinstall from booting the osx disk, but i'm affraid it'll just apply the same settings again and keep me locked out. I need files off of my hard drive since i'm in school and have several assignments that i have not backed up at all.
Any help would be greatly appreciated

after searching the forums deeper i found the solution. it's now working. you may delete this thread.

HELP! Can't get past the blue screen when booting up...

Hi,
Please can anyone help. I've searched the web and found possible causes of the fault but not a solution....
I upgraded my hardrive, used SuperDuper! to clone my drive, make it bootable etc then transferred the new drive to my Macbook Pro.
Now, every time a boot it up with my account set to auto login, it freezes on the blue screen. It doesn't go any further.
I've entered in Safemode, added a second 'Admin' account and set the login preferences to show the login window. Which allows me to log in as the second account holder. This works in normal mode, and then once logged in, i can switch accounts to my normal account.
This is the only way i can use my account.
I've looked at the fonts and used 'Font Doctor' to fix them. I can't seem to be able to fix my preferences (com.apple.programename.com), Onyx doesn't seem to fix it and i've no way of finding out if a preference file is causing this myself.
I've also done an OSX reinstall then software update. No good!
I've tried so many things as advised by various people online but it's clear to me that it's a) Account issue, b)Startup issue once logged in.
Please can anyone advise? I'm assuming that it's only related to my account, and that it's to do with the startup of the account...
I have OS X 10.6.8 on a macbook pro unibodied (1st gen, Aug 2008).

Thanks. However, i found a lot of errors so i chose not to act on what i didn't know.
This is how i managed to work it:
Activate ROOT user
Login as ROOT
Update to latest OSX 10.6 (was just released)
Restarted
Logged in as main user... worked fine. Not sure what i did but it worked.
I had tried all other methods but non worked...

What do I do if I get a blue screen following boot up?

I have a MacBook air pre - Yosemite OS. When I boot it up I get the apple badge and the loading circle and then it switches to a blue screen with the cursor in the top left. I have tried booting and holding D for the hardware test but I get no errors on both long and short tests? Can anyone help?

Yes sorry. It has OS X 10.6 I think. I last back up the data about 4 months ago.
The spec is as follows:
Apple MacBook A1342 13.3" Laptop (Intel Core 2 Duo 2.26Ghz, 250GB Hard Drive, 4096Mb RAM

Hanging on blue screen during boot (but Safe Mode OK)

Strange stuff with my iMac G5 -- machine boots normally, gets through Apple icon and spinning spiral, then hangs on blue screen and stays there. Mouse cursor moves but that's it.
Safe boot works normally, all safe-mode functions good. But need network, other services back.
History: Spent most of past week downloading huge, multi-gig file. It eventually downloaded successfully, but during process my wife put computer to sleep a couple of nights without halting download.
Didn't have adverse effect first time, but it froze Finder second and third times, necessitating reboots. Also killed wireless connections for all PCs in network those two times iMac needed reboot, had to reboot gateway as well.
Morning after download finished (Friday), iMac failed to wake up from sleep, wouldn't boot normally, had to go into Safe mode.
Additional RAM was recently installed, but has worked well. Safe mode shows full two gigs in use.
Solutions I've tried, without success:
-- Trashing network preferences in both user and system
-- Re-installing Finder and NetworkInterface apps using Pacifist
-- Removing recently installed extensions in System (extensions put back after that failed to resolve issue)
-- Removing recently installed Startup items (again, put back after that failed to resolve issue)
Clearly it's got something to do with the network interface, but I've tried everything I know how to do. Any ideas? I'm out of them.
Thanks in advance.

The Airport card is not removable in this model -- 2nd rev G5 iMac, with automatic light sensor.
But -- I think I've found what's wrong. Unfortunately there's no easy fix ...
It's most likely the bad-capacitor issue that plagued the 1st rev of G5 iMacs. (This particular machine was a refurb bought direct from Apple in the fall of 2005, so it's possible bad caps were put on during the refurbishing.)
I first heard about the problem a couple of days ago but figured a hardware diagnostic test would catch it. More online research reveals that the hardware test doesn't.
When I popped the case this morning to yank the new RAM, there were definitely a few capacitors that had domed tops. Nothing spilling out anywhere, which was what I was looking for, but I've since found out that even contained bulging is a sign of failure. The capacitors should be instead perfectly flat-topped.
So ... I'm gonna call Apple tomorrow morning and see how much it would cost to replace the mobo. There have been reports in forums that Apple sometimes offers to do it for free, even in cases occurring within the few months.
See this link for examples of Apple picking up the tab for complete mobo replacement: http://www.macosxhints.com/article.php?story=20090314071508354
If that offer isn't made, I will look into having the capacitors replaced. This is at the edge of my own technical abilities so I will first ask my techie friends if they can do it for $100 or so, plus parts ... and if not I'm gonna try to do it myself.
This guy shows you how and sells inexpensive parts to do it with: http://jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php
There is also a guy out in Missouri who replaces bad capacitors on motherboards for a living: http://www.badcaps.net/ Looks as if he'll charge between $80-120 including shipping and parts. So I may go that route.
In any case it turns out Apple did know about this issue back in 2005 and even instituted a program to fix iMacs that had problems stemming from it for free. (Dell Optiplex machines also had the same problem, which was traced back to a few Taiwanese manufacturers.)
Unfortunately there was no recall (Apple would never have lived that down) nor was the issue highly publicized. You had to wait until your own machine acted up, and then the free-repair program expired at the end of 2008.
I myself never knew about it until a few days ago, and I usually keep up on this stuff -- which is something I will make very clear when I'm on the phone with Apple tomorrow.

Blue screen - after booting into Darwin/BSD

Hi,
after I had the problem of my iMac G5 only booting into Darwin/BSD (which I posted here: http://discussions.apple.com/thread.jspa?threadID=1093517&tstart=0), I followed the instructions for recreating the user accounts, as described here: http://discussions.apple.com/thread.jspa?threadID=320663&start=0&tstart=0
Now I'm able to get to the blue screen, and the system doesn't exit into Darwin/BSD any longer. However, the Setup Assistant doesn't start either.
I only see an empty blue screen (I guess it's the GUI base screen) and the menu bar. The menu bar only has to items: one menu 'loginwindow', which doesn't have any entries. And the Apple-logo menu, which has the following menu entries:
- About This Mac
- Software Update...
- Mac OS X Software...
- System Preferences...
- Dock >
- Location >
- Force Quit...
- Sleep
- Restart...
- Shot Down...
- Log Out System Administrator...
The 'Restart...' entry doesn't work. I can, however, launch the System Preferences window.
Tail command of /var/log/System.log shows:
configd[41]: WirelessConfigure: 88001003

Any recommendations on what to do next?

2. shut down windows and re boot in OSX

Rthdaud.sys blue screens in boot camp

Hi all, have been playing around in boot camp (gaming for the most part) and twice now have, after a few hours of perfectly fine system running, been presented with a blue screen naming rthdaud.sys as the cause. As this is the realtek audio high-def driver, I assume it's part of the boot camp driver package and should be okay.
What would be the first thing to try? Should I reinstall the apple boot camp driver for this? Perhaps get the driver (updated version?) from realtek's website directly? Thanks in advance for any help.

Apple today introduced Boot Camp, new public-beta software for Mac OS X that lets users of Intel Macs boot directly into Microsoft Windows XP. While the move may contradict previous statements by Apple, the company said they still have no intention of fully supporting Windows on the Mac.
