Unusually long bootup followed by blue screen

So last night I decided to restart my MBP then when it came back to bootup, I got a gray screen with the broken file/folder icon. So I ran disk utility and repaired everything, one minor repair was made. Now when I try to bootup, the apple screen takes longer than usual and afterwards it gets stuck on a blue screen. Please help!

Try booting in single user mode.
For this, press and hold "apple + s" immediately after pressing the power button. It may give you the cause of error. Maybe with fsck, you can check your file system from command line.
Another way of seeing the cause of the error is to boot with "apple + v" pressed (verbose mode). You will see all the kernel messages, and all the outputs of init scripts.
After trying these, you can see what is causing boot problem.

Grey screen no apple followed by blue screen with vertical lines. Graphics and logic board replaced 6 months ago. What to do? I held down shift, it gets HOT HOT and makes noises. (for safety mode) followed by a blank grey screen and blue screen

grey screen no apple followed by blue screen with vertical lines. Graphics and logic board replaced <6 months ago. What to do? I held down shift, it gets HOT HOT and makes noises. (for safety mode) followed by a blank grey screen and blue screen. Then tried the other way (sorry, I think it's command alt delete? I don't remember) and it turned from grey (no apple symbol) to blue blank. Then third time, grey followed by blue with vertical lines, not blocky clear lines that you can see if you are close to it.
Thanks for any help!

You have to take the computer to the Apple store to have it checked out.

Dv6 Notebook "Black Screen" following "Windows Blue Screen" error message. Caps Lock blinking!

I have a HP DV6 notebook. I left my computer on overnight and the next morning I woke up to find a Windows Blue Screen error message. It said to restart my computer. I was in a rush so I just closed the lid. When I returned I opened the lid and the screen was black. I pressed the power button to restart it and I haven't been able to restart it since. I now have a power light, a black screen and the CAPS LOCK light is blinking twice then a pause! Please help!

Hi btgclark,
I understand that you are having an issue with turning on your notebook and the CAPS LOCK light blinks twice and then pauses. The following document 'Computer Does Not Start and the LEDs Blink or the Computer Beeps' will walk you through the steps that you need to follow. For your error code, it means that the BIOS has a corruption failure. This document will walk you through the necessary steps to get this resolved.
If for some reason this document does not resolve the issue please provide me with the model number to your notebook. I have included a document 'How Do I Find My Model Number or Product Number?'
Please let me know how this works out for you, thank you.

External display no longer working - stuck at blue screen

Hi everyone. I just don't know what in the bloody **** happened here.
Everything was working fine, I even had my macbook 13 upgraded to 10.5.6 and it always worked fine with my external DELL 2007WFP screen thru DVI cable and miniDVI adapter.
Suddenly when I got home today and plugged the miniDVI adapter, I saw the screen blinking forever at the blue screen that usually fades out to both screens with extended desktop turned on.
If I unplug the miniDVI adapter, everything gets back to normal on the macbook screen. I plug it again, I get the blinking blue screen.
Tried rebooting, unplugging everything else from the external screen, no luck.
If I boot the macbook with the external screen on and the macbook closed, then it is recognized fine and I can use it, but when I want to use both screens, it will blink again.
I need to use both screens as that's how I arranged my workspace.
Again, everything was working fine yesterday.
Thanks

Did you ever figure out what was doing this, and more importantly, did you get it fixed? I have the same thing happening to my macbook 13. It has worked fine in the past with external displays, both mini-DVI to DVI and mini-DVI to VGA, and many types of monitors/projectors. All of a sudden last week, i try to connect to my external monitor and I get the flashing blue - dark blue - light blue - repeat...
I tried the command-f1 trick to switch displays, and it sits there for a second, my desktop will flash onto the external monitor for a second, and then it'll give up and go back to the repeating blues.
I ran the hardware test, both the short and the long, to no avail.
I tried with the lid closed and an external mouse and keyboard. I tried this both from the startup and from when the laptop was already on.
Any ideas? Time to go to the genius bar?

Repeating mouse freeze followed by blue screen then back to normal

Hi guys, if anyone can help with this, I'd really appreciate it... it's really driving me nuts! Every few minutes, my mouse freezes, the screen then goes totally blue for a 10-20 secs. The screen then goes back to normal for a second or two then back to a transparent blue screen (showing my desktop etc. behind it) for another 10-20 secs then back to normal after maybe one or two more flashes of blue screen. It's got so bad that I can't use the computer any more.
It's a G4 (2x1.25Ghz) with mirrored doors running 10.3.9 with 1GB of RAM
Thanks,
David.

There are so many things that there is no clear symptom or cause as to why the system is partially hung.
I would familiarize myself with the system, buy a book (or two) starting with "Mac OS X: The Missing Manual"
http://www.apple.com/macosx/resources/
About This Mac... more -> System Profile
will display memory condition, log files (system, panic, etc)
Depends on how much memory, what you are doing, whether you have a driver issue, or maybe a corrupt preference, font, directory.
Unlikely it was a parity error, but if it was a kernel panic, it would not leave it up to your imagination, it would be in clear black and white.
You could run your Apple Hardware Test; Disk Warrior (or just Apple's if you haven't yet bought DW).
Backup and boot from another drive to run repairs.
I would be more concerned over lack of a UPS and a power issue/outage or 'brownout.'

Freezes, kernal panics, long startup, hanging on blue screen...

sometimes on black screen, freezing when desktop appears, freezing when
using Safari and Mail, text edit and have not had a chance to see what it does in other programs.
This had been a growing problem from the first kernal panic I had about month ago after a complete reinstall in December. Also the fans run loud.
After reading more about kernal panics, i'm beginning to think this is a hardware problem and I should replace by RAM with what was built for this
G5. I cleaned it out yesterday. it was pretty dusty because it sits on the floor. Would a professional cleaning be in order?
I think I'm asking: what software approaches should I take and what physical approaches should I take to isolate the problem the soonest. Can someone send me a list off Apple's site and I'll start to go through them before I have to, yuck, reinstall all over again?
Thanks guys.
If this helps:

HP 6525 Photosmart Blue screen with On/Off icon and "B8564450" message

Found my HP6525 in the following state:
- Blue screen, with an On/Off icon and various error messages
- Cannot turn printer off; press On/Off switch and HP logo appears and then an new or same Blue Screen appears with the same or different error message all starting with the letter "B"
- Removing power cord from printer, and reattaching results in same scenario
- cannot really turn printer OFF, just multiple instances of the Blue Screen on display
- Cannot do anything else since there are no other controls other than the touch-screen.
- Printer was set up for Wireless/Bluetooth operation with the two computers having wireless access being a
- Windows 7 Laptop
- Apple iPad
Both worked flawlessly before this???
What happened??
-Unfortunately, this is the FIRST occurrance of this level of issue with a long line of HP inkjets?????
How can I reload firmware?
- connecting via USB cable, and doing setup or something different?

Hello,
This seems like a hardware issue, I would suggest calling HP @8004746836 and see what options they have to replace or repair the printer.

Has anyone else experienced blue screens and continuous reboots on 5S

I picked up my silver 5S 32 GB at the Verizon store Friday morning. Throughout the morning I noticed that I would hit the home button and it would be powered down. I loaded the .1 patch assuming maybe it was a glitch. I went through the rest of the day with a couple more home button/powered down situations. When I got I home, I plugged it in to iTunes to recover a backup and following the restore it went into blue screen reboot cycle. I performed the soft reset and restored the backup 3 times with the same results. The soft reset was the only means to stop the reboot cycle. I then tried 3 times doing a restore from the cloud with the exact same results. Finally I did a from scratch install thinking my backups were bad. It would stay up awhile but then eventually go into the blue screen and reboot. Sometimes the cycle wouldn't occur in that it would boot up to Home screen following the blue screen. I took the phone to the Apple store the next day, they looked it over, witnessed the blue screen and confirmed there was an issue. I then went to the Verizon store and swapped it for a Space Grey 32GB. I experienced the exact same cycle with the grey so I called Apple. I have spent 3+ hours working through this with a very helpful agent. Turns out a have 2 bad ones in a row! The way I can almost instantly get it to go to blue screen is clicking the Photos icon. Now I am waiting on a second replacement at the Apple store. We have done the soft reset, the hard reset, and the phone restore so we know now that the backup had nothing to do with it as I can do a restore and still have it blue screen after clicking Photos. Anyone seeing anything like this?

Searching for others who might have the same problem increases your chance of finding a solution. Common sense in troubleshooting devices dictates you look for others who might have the same problem in hopes someone already has a solution. Your comment is irrelevant and leads one to think you are spoiling for an argument. Why???

Macbook won't boot up blue screen, volume check failed

Yesterday, my friend's Macbook wouldn't boot up properly. First it came up in terminal mode with the following message displayed:
disk0s2: 0xe0030005 (UNDEFINED)
Today did a re-start. Could not get into Safe Mode. White apple logo screen ran for 3 minutes with progress indicator (circle of sticks) followed by blue screen with progress indicator for 7 minutes, followed by blank blue screen.
Started up in single user mode and ran fsck
Results were:
fsck -f
**/dev/rdisk0s2
** Checking HFS Plus Volume.
** Checking Extents Overflow file.
** Checking Catalog file.
disk0s2: 0xe0030005 (UNDEFINED)
Invalid node structure
(4, 34)
**Volume check failed.
localhost:/root#
This Macbook was purchase approximately 60 days ago. Is there a simple fix to this before going back to Apple?
Thanks,
Joe

Hello Joe.
Although similar to running fsck, boot from the Tiger install disc #1 that shipped with this MacBook and run Disk First Air repair on the hard drive.
If there is a hard drive directory problem that cannot be successfully repaired after running DFA repair several times, the directory problem is substantial and the options are using a more substantial disk repair utility such as Disk Warrior (not sure if DW has been updated for a Mac with an Intel processor or not) but if so, there is no guarantee but DW has been known to work miracles or reformat the hard drive HFS+ (or extended) with Journaling enabled and then reinstall OS X and all included software.
You can call AppleCare but they will have you or your friend run DFA repair and do the same. Unless there is hard drive damage that is covered under warranty, there isn't much else AppleCare can do and hopefully your friend has/maintains a backup since this is a good example for why maintaining a backup is so important.

G35 Qosmio Upgraded / Blue screened & No recovery Options - No help from Toshiba $$$

I am working on a system for a customer. It comes to me with big headaches. System came with Media edition bust customer used an upgrade to Vista Disc and used it for a while before he corrupted both drives to the point where he can no longer use it without blue screening. He brought it to be wiped out and factory reinstalled. Here is what I did:
1: Put the raid drivers for xp on a USB floppy, loaded the system formatted the drive (s) and proceeded to load installation disc. system gets to about 8% file name is cyycoins.chm and it stops saying it cannot copy file. If you skip it, the problem persists with other files.
2: I put in another CD-Rom as well as other original Media edition discs, same scenario.
3: Downloaded a bios flash via floppy and pushed that through, tried to reinstall but with same problem in same file locations.
4: Tried to use customers recovery discs but it gets to a point and says WRONG MACHINE and goes no further.
What does the phone support tell me, he says oh, this is a problem that I cannot furnish to you via telephone or any other support you will have to bring it in to a support site,. well as indicated I am a repair store, I dont like to give up my work or feel as though it would be good for business to tell the customer sorry you have to go somewhere else that will obviously charge a whole lot more then me or even lie to him but what else can I do. Not to forget to mention that the closest place is over 40 miles away. Maybe if Toshiba was not so stringent who is eligible for that status quot then maybe there would be closer options. I personally am owner / operator and dont have time to go to their specific schools for this crap I know enough to repair microchips on motherboards for pete sake.
I have not attempted to pull the CMOS battery to reset the board, not sure if that would work anyway. I also have not tried a full version of vista, customer stated that he did not want it anymore because of the issues he was having with the system while it was installed so he wasnt going to go that route.
Listen any support is appreciated, unfortunitly with this system it is not so cut & dry. Also anyone know what code I can use to change the Raid Array, I am sure that would help too. Thanks

You can google cyycoins.chm and find many people having problems with it. Some it seem are due to a custom Windows disc.
I would recomend the recovery disc, as it will do it all and put all drivers in place. It is simple and complete. Much less work. You mention he has that disc but you get the wrong machine error message. If the disc is the correct one for that model, then the DMI needs to be written for that model. For some models there is a program on Toshibas website to do it. If there isn't for this model (Which I don't think G35's are covered) then you need to take it to a Toshiba Authorized Service Provider to do it. Since it is just software that they need to run, maybe they won't charge much. But I have no idea about that.

Blue screen following effort to fix Darwin/BSD screen

Our iMac began having issues yesterday and when rebooted it went to a screen that said Darwin/BSD. I followed previous post information (http://discussions.apple.com/thread.jspa?threadID=320663&start=0&tstart=0) to try and work through the problem. I got to the point where it said that my disk appeared OK and followed the other instructions until it said to type reboot. Now when it reboots it looks like it is going to get to the log in screen however it gets to a blue screen and is stuck. From time to time it will lighten quickly with the little timer circle and then quickly back to the blue screen. ANY HELP??? I am frustrated at this point.

Hi Willeford, and a warm welcome to the forums!
"Try Disk Utility
1. Insert the Tiger Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot , (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
(If perchance you cant Find your Install Disk, at least do the Safe Boot part above).
The usual reason why updates fail or mess things up, or things don't load/run, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates again, or even do an A&I if you have enough free disk space.

The combo update for Intel-based Macs...
http://www.apple.com/support/downloads/macosx10411comboupdateintel.html
Repair Permissions before & after re-install, then reboot again each time.
If all the above fails, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...
http://docs.info.apple.com/article.html?artnum=107120
Just be sure to select Preserve Users & Settings.
I only use Software Update to see what is needed, then get them for real via...

That way I can wait a week or so, check the forums for potential problems, and get Permissions & such in order before installing.

Light Blue Screen followed by nothing

Hi there,
I'm wondering if anyone can help me solve a problem i'm having with MacOSX 10.3 and a iBook G4 which I recently purchased.
The iBook G4 boots the Apple Hardware Test cd fine and I'm able to test the hardware which all passes (Logic Board, Memory, Mass storage etc), however on some occassions when I try to boot the install disc's which came with the unit it will begin to boot it and then stops with a light blue screen (which is seen as the background for the MacOSX install). Sometimes I do have success and it will load the setup as it should but other times its just as I describe it. There is no cursor or spinning colored disc on the screen either when it happens. It just a blank light blue screen which doesn't do anything.
Is this a logic board fault or a HDD fault?

Hi cornelius and ali brown,
Thankyou for your replies. I'll have a look at those articles and see how it goes.
In response to your question Ali, that was my post. I just felt this type of question was probably more relavent in here.
As you may know I was able to get the installation going after running in verbose mode however the install only required the first disc of 3 - 4 (can't quite remember). I did also select "Archive and Install" which saves the current installation for future access. (someone suggested it on this forum or another one)
After the first CD was done, it asked to restart the machine. I clicked restart and it booted fine (no longer get the kernal dump on bootup) however it doesn't continue after that. I simply see the Apple logo plus the spinning gear which then goes to a light blue screen and stays there. It is similar to when I tried booting from the install disc.
It does the same thing in verbose mode and I can't see anything from the startup process which might be causing the problem.
I then left it for a few days whilst I did a bit of research into the problem. Then the other day I booted the iBook and it began to continue with the installation. It asked for disc's 2 and 3. After finishing disc 3, the installation was complete and it began to show the welcome video which then turned into a cube which froze about 45 degrees into its turn and wouldn't respond. The sound was also repeating (just your common lockup).
I powered the unit down and attempted to do a clean install but it began to do the same thing as before (boots install disc and loads a light blue screen). Verbose mode does the same thing at that point so I was unable to perform a clean install.
Hope there is enough info provided to help better determine what is causing the problem.
I'm using Panther 10.3, Tiger is not installed (I didn't correctly list the details for the iBook - apologies for that).
I can boot the Apple Hardware Test cd fine which works as it should. I have no problems with that. However, whenever I try to boot from the HDD it just does what I described above. I see the Apple logo with the spinning grey gear which then goes to a light blue screen and not much more happens. It also does the same with the Panther install disc's. However, it works on some occasions.
The disc's are the ones which came with the unit so I can only assume that they are original system install disc (grey in color).

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:

MacBook Air spends long time in blue screen

When my MacBook Air boots from the internal hard disk, it spends 30 s hanging on the blue screen. This seem excessive. When I boot it from an external hard disk, it spends 1-2s on the blue screen. In itself it doesn't bother me, but I worry it's a symptom of some bigger problem.
Background: my hard disk broke, Apple installed a new hard disk, and I reinstalled from a TM backup using migration assistant. Everything works fine, I checked the new hard disk using disk util. Only the long blue screen pause seems out of sorts. Could some junk have come over when I used migration assistant? How could I identify it?

Hi
This is usually caused by a StartUp Item, Launch Daemon or Launch Agent. Try a Safe Boot, to see if it makes a difference. If so, then have a look in the following folders:
/Library/LaunchAgents/
/Library/LaunchDaemons/
/Library/StartupItems

Very long blue screen with spinning sprocket at shut down

When I shut down my Mac Mini, after everything closes properly I get a blue screen with a spinning sprocket for a very long time. I end up having to power down and restart. It happens most of the time, interupted with an occasional proper shut down.
Any ideas on what this means?
Thanks for your time.
Kevin

Check Console in Utilities for messages from around the time of the shutdown. Check system.log expecially, but look around at some of the other logs as well. Also, try booting in Verbose Mode, CMD-V at startup. This will scroll text of the bootup sequence before it goes to the regular screen, but the next time you shutdown, it might scroll text of the shutdown sequence and give a clue as to what's going on there. Be ready with a camera or notepad to write down what you see.
