OSX 10.5.8- Stuck at blue screen during startup

After the Apple logo appears the screen goes to blue and stays there. I am also running BootCamp and can access Windows with out any problem, but I cannot get to the login screen for OSX. I have already reset my PRAM, reset my SMC, removed all ApplicationEnhancement files (I actually didn't have any), and started up in Target Mode from another computer and done a disc repair. I can access all files in Target mode without a problem. I have not archived and tried re-installing Leopard, I'd like to try and avoid this. I am also using a third party internal hard drive, but only for storage, this is not my startup disc. Does anyone know any way I can fix this?

Getting light blue screen during startup for 3-5 Seconds

I get a light blue screen during start up for about 3-5 seconds. It shows the spinning image for loading, once its done that goes away and then it goes light blue for couple seconds then back to the white page with the apple logo then brings me to the user login page. It also takes longer then usual to start up, load dock and the menu bar. I've read around and it seems people are saying its normal? but this just started happening.

Which model Macbook Pro do you have?
It also takes longer then usual to start up, load dock and the menu bar.
How large is your hard drive and how much hard drive space do you have left?
Go to your Account/Login Items and get rid of all you do not need.

IMac stuck on blue screen on startup

I recently purchased an iMac 21.5". It is running Mac OSX 10.6.2 (Snow leopard). When I turn it on it passes the screen with the gear and the apple logo, but gets stuck on the blue screen, with only the cursor showing.
I have already tried:
1. Booting into safe mode and deleting all startup items.
2. Resetting PRAM and NVRAM
3. Running Disk Utility and repairing the disk.
Anyone have any suggestions on hwo to fix it?

Try this:
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 by restarting the computer. After the chime press and hold down the COMMAND-S keys until you see white text on a black background. 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).

MacBook Pro w/Snow Leopard stuck on Blue Screen during Reboot

Hello:
I posted this on other forums without any responses, so hopefully, I can get some help here.
On Sunday, I emptied my cache on Safari and my computer stayed frozen for a few minutes. I decided to re-boot, but every time I do so, it goes from the gray Apple screen to a blue screen and stops right there. I don't get the spinning wheel, but rather the black arrow that I can move about the blue screen, but nothing else. Here's what I've tried with no success.
1. Re-booting via Safe Mode (Command-Shift). Instead of freezing on the blue screen, it asks for my password and after a few seconds it stops on the Snow Leopard Pink/Black Stars background. Same result, only the background is different
2. Resetting PRAM - No luck
3. Re-booting with the Snow Leopard DVD and using Disk Utility. I follow the necessary steps online. No luck
Any help with resolving the problem would be appreciated. Thanks!

As a point of reference, here is a sample of the errors that were discovered during repair disk.
Volume file Count
569070 instead of 569075
Volume Directory Count
175474 instead of 175469
During "Repair Disk Permissions" I get this message:
Warning SUID file "System/Library/Core...has been modified on will not be replaced

Can't get past the Blue Screen during startup

I decided to upgrade the 4/8/08 firmware on my aluminum bluetooth keyboard this afternoon using my mac mini. Shortly after the procedure started, something happened to the keyboard and it could not complete the install. I tried a second time, but again no luck. I then decided to replace the keyboard batteries and try again, but I was no longer able to connect the keyboard to the mini.
I decided to restart the computer and try the whole procedure again. But after the grey screen comes up with the Apple logo, the mini went to the blue screen with the spinning gear, then the mouse appeared in the upper left hand corner, then a little later the gear, then nothing, then the mouse, then the gear... I could never get past this blue screen.
I plugged in a wired keyboard and was able to startup 10.5 using the install DVD, which allowed me to check and repair the permissions and the disk. After a restart, still stuck on the blue screen.
I tried zapping the pram. Still couldn't get past the blue screen.
I was not able to start up in safe mode (is the timing critical for when to hold down the shift key?)
I started up in single user mode and attempted to move the preference files as described here:
http://docs.info.apple.com/article.html?artnum=106464#symp1
but got an error that I did not have the correct permissions. I assume that is because I was trying to save the preference1.old (and preference2.old, etc) files to the root part of my hard drive.
Any suggestions? Does it make sense that upgrading the firmware on a bluetooth keyboard could take down the whole computer???

Disconnect all peripherals from your computer.
Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
Restart your computer when done.
Repair permissions after you reach the desktop-http://support.apple.com/kb/HT2963 and restart your computer.

My mac pro only shows a blue screen during startup? how do i get out of this to the desktop?

Cannot access the desktop, only the Apple sign and pinwheel icon come on, after a couple minutes it goes to blue screen only. Have held shift during bootup to start in safemode, but this doesnt even allow you to choose safe mode. Please help.

Try holding option+Apple Command + s keys to get into single user mode. May be a little unnerving as it will get you to text based screen. Grab a pencil and paper and copy the commands that are listed also pay attention to the spaces.
/sbin/fsck -fy <return>
If the it says File System Modified hit the up arrow key it will repeat the line you typed. Hit return.
If it DOES NOT say modified then type in the second line.
/sbin/mount -uw /<return>
At the prompt type reboot<return>
Let us know if it helps.
Ciao,

X60 Blue Screening during Startup

Hi,
My X60 currently goes to the blue screen every time it gets into the Windows loading screen. I can't run safe mode, last known configuration, etc. without it blue screening either. I've run the built in Thinkpad diagnostic software and nothing fails. I've been told this may be a hard drive issue, but would appreciate any other advice.
Thanks

This just happened to me. Are you running Svc Pack 3? If so you'll have to restore to factory install - load up in safe mode to save your personal files then reimage.
Annoying, but went smoothly for me

IBook G4 Freezes at Blue Screen During Startup.

iBook G4 933 MHz
Mac OS X 10.4. Tiger
640MB RAM
40GB internal ATA hard drive
Computer boots but then quickly locks up.
If I immediately restart, then the iBook hangs at the blue screen before the Mac OS X progress screen appears.
If I remove the battery and unplug the power cord then allow the computer to sit for at least 30 minutes, able to fully boot, but then the machine quickly freezes up.
I assume the problem is heat related?
I have so far:
- Totally disassembled/reassembled
- Reset PRAM
- Reset NVRAM
- Reset PMU
- Unable to do target disk mode
- iBook freezes same way when booting to Mac OS X install DVD
Able to boot to shell command line mode no problem.
FSCK reports no issues with the HDD.
Sometimes during startup a fan turns on briefly, but not every attempt to boot.
Yes-- I know about the 'solder' issues with iBook G4 logic boards, but I do not think the above is related. The VGA works fine.
Thanks for any assistance that can be rendered.

After a month, I have been notified by Superior Reball that the logic board has been repaired. I promptly made payment of $35 and the board was shipped back to me on June 17 via USPS Priority Mail Delivery Confirmation. I have received the tracking number and anticipate receiving the package by June 20.
In my situation, well worth the wait for only $35.
Even though I chose to totally disassemble the iBook, Superior will do the disassemble/reassemble for $75.
I would not have done it by shipping the entire iBook, though. With the higher shipping cost, insurance, having to send out the hard drive with no back up, the higher repair cost, etc.-- in the end a prohibitive expense. I could probably buy a used iBook G4 for no more than $200, to put things in perspective.
In summary, Superior Reball had a great price, good enough communication (they answer the phone, but not e-mail) and it looks like fast return shipping. It took a lot longer than the ad states, so I am applying the old 'price, speed, quality-- choose any two' rule here.

IMac Freezes on blue screen during startup after installing itunes 9.2

I let iTunes update to 9.2 today on my 27" iMac quad and when it restarted itself it froze on startup at the blue screen. The blue screen switches between two different shades but never exits that loop. I CAN boot in safe mode (which is what i'm doing right now).
Thus far i've tried:
- reinstalling itunes
- resetting my pram
- uninstalling itunes
- removing itunes startup app
I still cannot boot normally. Help!

You might try booting from your install CD and running disk repair in Disk Utility.

Lenovo 3000 N200 - Blue Screen during Startup

I have a 3000 N200 laptop running Windows XP which has begun showing a blue screen error then restarting during startup.
When turned on, it shows the Lenovo logo page then a page saying Windows did not start successfully last time. When I choose to start Windows in both normal and safe modes, the XP startup screen comes up then a blue screen flashes up for 1/2 a second then it restarts. I disabled restart due to system failure and read the error code, details are below:
UNMOUNTABLE_BOOT_VOLUME
Technical Information:
*** STOP: 0x000000ED
(0x86F5F030, 0xC0000006, 0x00000000, 0x00000000)
Choosing to start with command prompt loads files up to...system32\drivers\mup.sys, then freezes and restarts.
I have tried to enter the rescue and recovery using the LenovoCare button and F11, but this begins to load then freezes on the first screen.
I rang Lenovo and they sent recovery discs but these have not worked, bringing up the Rescue and Recovery first screen with the Boot CD and freezing as with the LenovoCare/F11 buttons.
I will be ringing Lenovo again tomorrow but any advice in the meantime would be much appreciated.

Grey, red, green, blue screen during startup

Hi,
today my macbook 13" unibody was working well. Then I put it in sleep mode and after it woke up I got grey, red, green, blue, vertical stripes, horizontal stripes screen. I tried to reboot my macbook and always the red, green, blue loop. I tried a cmdoption+pr boot with no results. I then tried to remove the battery and push the start button for 5 sec. but no results again.
I've tried to boot with the C button and the installation disk but I got always the red green blue loop.
What else can I do to solve the problem?

We are experiencing the same issue on a Macbook A1278 13.3" Aluminum Notebook. Has anyone found a solution to this issue? Thank you.

Stuck on Grey Screen During Startup

I updated to Yosemite on Saturday and everything has been working fine, I have been able to shut down and startup as normal until today.
Last night I forced my Early 2011 MacBook Pro to shut down and today it will no longer get to the login screen.
I hear the chime, the Apple appears with the Yosemite status bar underneath, it takes a long time to get about halfway then both the Apple and status bar disappear leaving just a blank grey screen.
- I can get into Single User mode, using "fsck -fy" it reports that everything is OK.
- I can't get into Safe Mode.
- I have reset PRAM
- I have NOT reset SMC (is it worth a try?)
- I have a bootable Yosemite USB, holding option I can select that but instead of presenting the Utilities window it just brings up the Apple and status bar then grey screen. For some reason my WiFi network isn't in the list either. Also, the image of my hard drive that appears has a custom icon that I haven't used for at least 5 years, very odd indeed.
I'm at a loss, any help would be greatly appreciated.
NOTE
My left fan is faulty, I have ordered a new one online. I have been using SMCFanControl to monitor it, if the computer has been feeling hot I have been increasing the RPM for a minute to cool it just to be safe until the new fan arrives. Last night I increased the RPM and SMCFanControl became unresponsive which is why I forced the computer to shut down because I couldn't reduce the fan speed back to normal.

I am able to get into Internet Recovery Mode but eventually the globe disappears and it's right back to the Apple and status bar then grey screen again.
When holding Option only my hard drive shows, there is no recovery drive option.

Please closely follow Apple's advice in Gray screen appears during startup. There are a number of steps to take, be methodical and follow the directions closely.

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.
