Powerbook hanging on "Blue Screen of ????"

Ok, I've got a 12" Powerbook here that no longer boots up. It hangs on the blue screen right after the gray apple and before the login screen. I tried a complete re-install (Tiger) several times, each time using different security options like zeroing out the data on the drive, etc.. I've reset PRAM, NVRAM, tried different hard drives, booted off external drives, you name it, I've probably tried it, and it always does the same thing... it just hangs on the blue screen. The weird thing is I can boot into safe mode just fine. There are no start-up items or log-in items to delete under the user, I even tried creating a new admin user, then deleted the original, nothing worked. I am truly stuck, I've worked with Macs for years, this is the first time I have come across this particular problem, any suggestions would be appreciated!

Have you run the Apple hardware test, or either of the TechTools tests? Find your original OS X disks, which will say in small print on the first one's label 'AHT Version x.x'. Insert it and reboot holding the option key down. Choose the Apple hardware test, click the arrow to the right and follow directions. Choose the extended test when prompted. Does that give any error messages?

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.

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.

MacBook Pro hanging with blue screen and spinner after installing Software Update

Hi I was wondering if someone could help me with this current issue. Just a few hours ago I finished reinstalling Mac OS X Snow Leopard in my MacBook Pro. I performed a clean installation as part of a yearly spring cleaning that I do on all my systems to keep them optimized. So there was I downloading some software updates which included the combo update of OSX 10.6.8 and others. The updates finished downloading and the system logged out to install the updates, when the updates finished installing my MacBook proceeded by logging out into a blue screen and show a gray spinner similar to the one seen when you start your Mac. Here's the problem after 2 hours the system is showing the spinner and the blue screen, I think that my computer has just hanged in the reboot process.
I was wondering what should I do? Do a force restart? Or leave it overnight?
Also, where can I find any information on what error is causing this issue?
I appreciate your responses and help.
By the way, I installed Mac OS X from a USB stick that has the original image of the disk installer that came bundled with my computer.

Force a shutdown. Do not restart yet, but first do the following:
Repair the Hard Drive
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, 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.
Next, boot into Safe Mode then restart normally.
Hi Kappy,
Checked the hard drive after forcing a shutdown and booting from my Snow Leopard Installer USB Key and the status of the HDD says "Verified". I ran the repair and the volume was repaired successfully. Clicked on "Verify Disk" and it says "Macintosh HD appears to be OK". So I ran a second repair and again no errors were reported.
As suggested I booted back again in Safe Mode and restarted normally. All software appears to have been installed successfully. But I don't understand why my computer hanged and showed the spinner after installing the updates in the blue screen that appears just before rebooting. I am aware that the system shows that spinner after a OS update but the longest it lasts is 30 seconds at the most in my previous cases.

MacBook Pro keeps hanging at blue screen when starting up. How do I get around this?

My Macbook has been working just fine for a while, but recently today, it just started crashing on me a lot. This is NOT a kernel panic, but the screen suddenly goes blue and hangs. Then I am forced to restart it.
When I restart it normally, it stops going on the gray screen. I try Safe Mode, but it then suddenly goes to said blue screen again.
I can't even get back onto my computer. How do I solve this issue?

Bump. Really need help on this.

IMac G5 ALS hanging at blue screen

Hi -- I've read variations on this problem, so hopefully I can provide enough information to get a solid thread started.
On startup, my iMac G5 hangs at the blue screen. I've run the install discs, repaired permissions, checked the drive, all successful. Also tried the AppleCare CD, Techtool said all systems passed inspection.
I can boot in safe mode, no problems there.
I tried archive and install, but after restart had the same trouble.
I tried booting in single-user mode to see what the log revealed, and the system seems to hang at the following:
airport link active
in6is_addrmulticast = 0
flags = 0 fails
can't assign requested address
wide area service discovery disabled to avoid crashing defective DNS relays 192.68.1.1
workaround Bonjour unknown error = 0
I notice that some of the wifi networks in my apartment complex are recognized in single-user mode just before the system hangs, which is odd.
I've tried applejack to repair the cache and preferences, but no progress.
Next step appears to be wiping the drive and reinstalling the OS, but thought I'd check here first. Thanks!

I altered the TCP/IP settings, but still no luck, so I proceeded with a full erase and install of 10.4. Much to my dismay, the system still refused to boot after the installation was complete.
At this point I'd run across some threads discussing the capacitor cap failures of the iMac G5's, so on that hunch I popped the back off to take a look.
One of the capacitors is indeed leaking out of the top, so I'm taking the unit in to the Apple store today to receive what will mostly likely be a death certificate. This unit is a refurb and the extended repair program ended in Dec. 2008, so I'm thinking my options are limited.
I'll post back with the Apple store response just in case anyone might find it useful in the future.

Won't boot, hangs on blue screen

i was doing a software update of a bunch of things and the system ended up hanging for a very long time so i did a hard restart. when i turned it back on it went on very slowly, and got hung up at a blue screen.
i did another hard restart and it came on (slowly) but when the desktop loaded it only loaded the dock, and kept having an error dialog box pop up that said that 'Spotlight' was not loading, i could try again, ignore, etc.
i am now running the disk utility from the start up disk to check the hard drive. its possible this is getting hung up as well.
originally i came to here to see if there was a way to reinstall spotlight from the install disk. but with the disk verify getting hung up i'm a little worried. any thoughts?

You interrupted an installation in progress. This is bad news. You should always give it all the time it needs. Unless you have a Time Machine backup or a clone on an external drive, you might have to reinstall from the DVD. (And if you don't have either, it's time to consider getting some kind of backup. I would never do a major update without knowing I can revert to the backup if necessary.) In !0.6 this should preserve your settings and apps. When you are finished, install the 10.6.4 Combo Update.
http://support.apple.com/kb/DL1048?viewlocale=en_US
But before you do that, you might see if you can get it to boot in Safe Mode by holding down the shift key at startup. This will take much longer than a usual booup; it's doing some checking and repairing, so give it time. If you are able to boot in Safe Mode, repair Permissions from Disk Utility in Applications > Utilities.
And it sounds like the system might have been choking on too many updates. I generally only use Software Update to see what's available. Then, if I want to do an update, I find the standalone at apple downloads and, if I'm doing several updates, I only install them one by one.

Macbook pro hangs on blue screen at startup

I've been having intermittent problems with my Macbook Pro starting up, but this is the first time it's completely failed to start up: I get the startup sound, the grey screen with apple logo, and then it just hangs on a blue screen, with a grey startup dial, and nothing happens. It was working fine up until this evening; it's confusing to say this, but it seems to have moods where startup is an issue. But I have taken it in several times for this very problem: the first time, they replaced my hard drive, the second I was told to reinstall OS X, and then add software back one program at a time. All I had on this machine was Adobe Creative Suite 4, nothing which would cause any issues. I don't even have any fonts on this machine!
Desperate to know what might be the problem; I've tried a few of the basic troubleshooting work arounds and none of them are working. Does anyone know what the issue could be?
Help!

If you get a external USB or Firewire drive, you can hold c and boot off the installer disk #1 that comes with your computer, the second screen in is a Utilities Menu and Disk Utility.
Select the EXTERNAL DRIVE and Erase, format HFS+ Journaled GUID partition.
When that's completed quit Disk Utility and your back in the OS X installer, install OS X on the EXTERNAL DRIVE.
When that's complete quit and reboot hold down the OPTION KEY and select the External drive to boot from.
Now GRAB THOSE FILES!!!
After that you can do what you want to the boot drive, if you can't fix it, you can always install OS X again (without formatting) and it should leave your programs and files alone. But if something goes wrong you have a copy on the external drive.
You can choose to Disk Utility format and reinstall everything, OS X, programs and files as well.
If for some reason you can't access your internal drive, either booted from the install disk in Disk Utility or via the external drive, it's possible your hard drive died.

Computer hangs on "blue" screen, not making it to desktop

Hello,
I don't know if this is a recent issue due to OS 10.5.3 or 10.5.4 but recently I've been experiencing hangs when starting up. I get to a "blue" screen. Sometimes I'm just stuck there, other times it goes to the desktop. I'm running 10.5.4 on a Dual 1.0Ghz MDD G4. Anyone else experience this? Any solutions?
Oh, I've repaired disk permissions and reset PRAM also. Same issues exist.
Thanks in advance!

Hanging on blue screen just before desktop launch

Hello,
I am a bone head and in System Preferences>Accounts I deleted/changed a few things and also changed permissions to the main hard drive (command-i), because I have two computers and I was trying to network the two computers over my airport, and I was trying to grant more than just access the drobpox to both computers.
Well My Tower I just finished reformatting, and reinstalling everything because it was hanging on the blue screen. Well my laptop is doing the same thing now. How can I avoid a reformt/reinstall scenerio at this point?

You can't. When you do bonehead things, you pay the price putting things back the way they were. Bootable backups/clones on separate HDs would mitigate redoing things from scratch. Sorry, I can't offer more help.

After update installs, hangs at blue screen

I just installed the latest update. The download completed, the update installed and then it rebooted.
On reboot, I get the chime, the Apple shows, the wheel whirls, it changes to the blue screen and then hangs there. I have left it in that condition for an 30 with no progress. I rebooted several times with the exact same results.
Any ideas?

I have the same problem on my MacPro but discovered a work around.
This works for me.
Powerdown then powerup with your finger on the eject button on the keyboard. My tray come out, then it will boot! Don't remove your finger until you have the User login list. I can then log in as usual and everything works! But if I do a Permissions repair I always have some more errors! Hardware test is fine. Everything OK until update.
Hope it works for you!

PowerBook Stuck at Blue Screen?

Hi there, I have a old Powerbook G4 15" thats having the common blue screen with cursor on startup error. Since then, Ive wipe OSX off and has been using Linux on this powerbook for some time and it works fine and i always though the blue screen issue is just a normal software issue. Recently, i decided to reformat it back to OSX 10.5, the installation went on smoothly and it completed without any issues. After rebooting, it stucks a the "blue screen with cursor" again. Heres what ive tried and some facts.
- Reseted PRAM
- Reseted PMU
- Reformatted the HDD
- Boot in Normal Mode and it stucks at blue screen v cursor
- Verbose Mode shows no signs of errors and it continues to blue screen n sits there.
- Boot in Safe Mode and it works
- Works perfectly fine with Linux
- HDD tested OK
- RAM tested OK
- Ran Disk Utility to check for permission errors.
- Tried removing Airport card.
- DVD drive removed (after installation)
- Was able to boot from 10.5 Installation DVD
- Can't do AHT (Apple Hardware Test) as i do not have the original DVDs
- Warranty is obviously over.
Does anyone has any suggestions for me? Thanks!!

15-inch PowerBook G4s with 1.5 and 1.67Ghz processors had a serious logic board fault that caused one RAM slot to fail. Use "About this Mac" to see if all the RAM installed is recognized, or remove one RAM module at a time and see it the computer runs properly on the other module.

Radeon 9800 pro 256mb hanging on blue screen

I'm deep in the waters of frustration right now, and am hoping someone here might have the answer.
About 3 months ago I was looking for a video card for me to run motion. I saw the 9800 mac special edition with 128mb video ram had rave reviews. At that time ATI was not making them. So I turned to eBay...
I purchased a card that was advertised as a Mac 9800 pro special editing 128mb. I later found out it was a flashed pc card. The ebay seller told me the card worked fine on all his mac's that he tested it on.
The problem I was having was the machine boots up, I see the grey screen with the Apple logo and spinning wheel. I see the blue screen where normally I see the login progress bar loading the OS. But with this card I only see the blue screen. I hear the hard drive churning, so I am assuming it is still loading the OS, but I cannot see anything. I can reboot in safe mode and the video card works fine.
Well... I assumed it was the fault of the card and that it was flashed. I returned the card to the ebay seller, who sent me another one, same results with that one. I returned the card to the seller and he refunded my money.
I put the money toward the just released Radeon 9800 Pro Mac Edition 256mb card. I just got it a couple days ago and am experiencing the same problems. I have tried everything... everything I know and still can't get the card to work? Here is a list of what I have done:
With the flashed card:
1. Shut off computer and unplugged it. Removed OEM video card and installed ATI 9800 card. Plugged the power supply cable for the card into the computer power supply cable and hard drive.
Problem Occurs: When starting up, the grey screen comes up with the Apple on it, then the screen turns blue, where I typically would see the progress bar of the system loaded up before the user login screen. I only see a blue screen at this point but can hear the hard drive working for about a min.
2. Restarted the computer in safe mode.
3. Logged in as Admin user and opened the ATI preference pane to verify it sees the card.
When the ATI preference pane was loaded the following error message occured:
A startup problem has occured.
Cannot connect to ATI TVOut Kernal Extension. Some features are not available.
Clicked OK and the ATI preference pane appears.
4. Close the preference pane and reinstalled ATI Displays 4.5.6. Restarted computer.
Problem Occurs
5. Restarted computer holding down AppleOption+PR to clear PRAM. Cleared the PRAM 4 times in a row, by allowing the chime to happen 4 times.
Problem Occurs
6. Shut computer down. Disconnected the DVI plug for the cinema display and connected a VGA CRT monitor. Started computer.
Problem Occurs
7. Shut computer down, disconnected the VGA CRT monitor. Reconnected DVI plug and restarted computer.
Problem Occurs
8. Started the computer in safe mode. Logged into admin account. Opened the ATI Preference pane.
When the ATI preference pane was loaded the following error message occured:
A startup problem has occured.
Cannot connect to ATI TVOut Kernal Extension. Some features are not available.
Closed preference pane.
Went to ATI site and downloaded:
aug2005-radeo-universal-rom-update.dmg
Ran the updater.
Restarted computer.
Problem Occurs.
9. Restarted the computer in safe mode. Changed the login preference pannel to automatically log into the administrator account. Restarted computer, waited for the blue screen, then walked away for about 2 hours with the computer on blue screen, hoping the system was loading or doing something.
Problem Occurs.
10. Put in the TechTools Pro CD, hoping to run some tests on the video card from the cd. When booting from the CD OS...
Problem Occurs.
11. Enabled Root user. Logged in as root and installed ATI Displays 4.5.6 from there. Restarted computer.
Problem Occurs.
12. Shut down computer and installed old video card.
13. On an internal hard drive in the computer. Wiped the drive and formatted it. Installed 10.4.1 on the drive. booted up into the drive, installed ATI drivers, shut down computer, installed 9800 pro video card, booted up.
Problem Occurs.
With the new 9800 for Mac ATI card with 256mb:
With original card, install drivers, repairpermissions, shut down, install new card
Set to restart in single user, give 5 min to see if ATI monitor startup item in user starteputems loads
Hooked VGA & DVIt in together, both showed blue screen
Reset NVRAM via open firmware
Reset cuda button
Take battery out, wait at least 10 min, re-install new battery, press cuda button
Reinstall ATI update 4.5.6
Reset nvram from open firmware
In ATI control panel, selected 'Force Single Display Operation'
Change display scaling to 50%
Download latest Mac OS update from apple & reinstall
Help?

I get dizzy just thinking about it.
I have tried installed a brand new OS, 3 different times on a different Hard Drive, still the card doesn't work.
I had one person suggest that it may be the card is not communicating with the OS Window Drawing module? (excuse my ignorance of what that is really called. I just know there is some program, possibly in the kernel, that is responsible for drawing out the OS windows.)
How can we rule out that it is a bad AGP slot?
•The slot works fine with my 9000.
•It works in safe mode with the 9800.
•I have installed a brand new OS, three different times, still doesn't work.
•I have used Apple Hardware test to test my hardware, the AGP slot didn't report any problems.
I am assuming that the AGP slot is working. Although I worry about it a bit, because by now I have swapped cards in it about 50 times in my troubleshooting.
Here is a link to a complete list of everything I have tried:

OSX Server Hangs on Blue screen at startup

We have an Xserve Running 10.5.8. We have been having strange issues for some weeks with client's logging in and their desktops being missing. Last Friday I noticed that the backup was not running correctly and I had a student who had lost her work mysteriously too. I decided to restart the server to see what would happen. On restart I cannot log in to the server either remotely or locally because after the white apple with spinner screen the machine goes to a blue screen with no login window. Services are up and running, I can view and use Server Admin and Workgroup Manager, and I can ssh into the server. I have trawled the internet in search of answers but all to no avail. There are some errors in the log but I am not familiar enough with these things to know which are significant to this problem. To further complicate matters the OSX server disk is nowhere to be found, hasn't been seen since well before I arrived on campus. I have ordered Snow Leopard for this machine but would like to get to the bottom of the issues.
I have booted into safe mode from ssh but this has made no change to the situation. I am relatively new to comand line management of macs so please don't assume I know how to use it like an old pro. I am learning rapidly.
Thanks
Lincoln

Well I never did come up with a solution to this problem. In the end the Snow Leopard discs turned up and an upgrade fixed the problem.

Macbook hangs on blue screen with menu icons, won't start

I am having an issue with my MacBook (2010), which won't fully start up anymore. It gets past the initial grey loading screen and starts loading a few of the menu bar icons in the upper right corner. Then it stops with only a few of those icons loaded, a blue screen, and no desktop icons.
The MacBook is running 10.6 (if I remember correctly, it's 10.6.8, but I'm not 100% sure).
Things I've tried already:
- Safe boot (doesn't work, no indication that it recognizes me trying to start it in safe mode)
- Resetting the PRAM
- Leaving it on for a long time to see if it will eventually start
I lost the OS disc a while ago, so unfortunately I can't boot from that. Any other suggestions would be welcome.

You might want to consider running the combo updater over your install to refresh your files.
Combo updater: Mac OS X 10.6.8 Update v.1.1 - 1.09 GB
http://support.apple.com/kb/DL1399
MORE INFO ON WHY RUNNING COMBO FIXES ISSUES
Apple updates available from the Software Update application are incremental updates. Delta updates are also incremental updates and are available from Apple Downloads (software updates are generally smaller than delta updates). The Combo updates contain all incremental updates and will update files that could have become corrupted.
Combo updaters will install on the same version as they're applying--no need to roll back or do a clean install. So if you think you've got a borked 10.6.8 install from a regular update, just run the 10.6.8 Combo Updater on that system.
"Delta" updaters can only take you from one version to the next. For example: 10.6.7 to 10.6.8. If somehow the 10.6.8 is missing something it should have, and that something isn't changed between 10.6.7 and 10.6.8 it will still be stale after the delta update.
