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!

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it. See below for how to clone a drive.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. 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 the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
       it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
      the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

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.

What operating system version, and do you have any backups of your data off the machine? TimeMachine? Option Key bootable clones? Storage? DVD's?
A reinstall of the operating system may be in order as a last resort, so if any of these steps on these links get you into the machine, make sure to backup your personal data (Music, Pictures, Documents, Movies) off the machine to a non-encrypted powered external drive regular storage drive (not TimeMachine as it might be corrupted too) and disconnect as soon as possible.
Good Luck and report back all what you tried.
Also report what change occured before this tragedy happened, was there a Software Update? A EFI firmware update? Etc.

IPhone5s stuck in recovery mode after lots of times displaying blue screen of death, cannot restore it as iTunes displays error 14 on verification, same time phone crashes again with blue screen.

hi, my iPhone5s is only 3 months old, it has been like a whole month now since it started crashing, displaying the blue screen of death, since yesterday it was in the loop of restart-crash, and now it is stuck in recovery mode after lots of times displaying blue screen.
I cannot restore it as phone continues crashing again with blue screen, when iTunes displays error 14 on verification.
help please, this phone is all the means of communication I have.

It's a hardware problem. That's it. You shouldn't bother yourself with this situation. Just see an AASP.

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.

EFI 2.0 update hanging at blue screen

I started the EFI 2.0 update for my macbook pro over an hour ago but it is stuck at a blue screen with the spinning wheel at the bottom. Anyone know whats up? What should I do? I don't wanna interrupt it if its doing something important...

If your EFI update is botched take your machine to the closest Apple Store or AASP and they will update it for you with a special disc they have. No you cannot download the data and burn it to a CD.

Using OSX 10.7.4. After waking, I frequently get blue screen and have to restart to resolve. Help???

I frequently get a blue screen of death after waking from sleep. I have to restart the computer to resolve the issue. This problem only began about a week ago, long after I updated to 10.7.4 on my iMac.

Mac OS X 10.6 Help- If you see a blue screen at startup
You may need to reinstall Lion:
Reinstalling Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

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.

Mac mini updated now just get blue screen and a spinning wheel

Mac Mini ppc with tiger.
Updated today (safari, OSX and itunes) after freeing up some space by copying files off to a USB drive. After reboot it gets to a blue screen with a spinning "wheel" and stays there for hours, never gets any further. Will boot to command prompt, target disk mode and a set of DVDs borrowed from work (which won't install as they are for iMac!) but not to anything GUI from the hard disk as far as I can tell atm. Disk utility on the DVDs reports no errors on the internal disk.
All was well before the updates. There was one "funny" but I'm not sure if its relevant. During use today the desktop appeared to get bigger than the screen when changing the screen saver to a snow flake one I used last Christmas (with no problems). As the mouse moves around the screen the screen scrolls in the opposite direction (only about 5 pixels) as used to happen in the old days on my PC when the graphics cards supported higher resolutions than the screen did.
Of course, as luck would have it, I can't find my original tiger disks!
Help!

Safe mode likely won't help, but it is achieved by holding the Shift key down during reboot - press and hold down when you hear the chime. It takes a while longer to boot into safe mode than booting normally, and it loads only core MacOS modules.
One issue that was a perpetual risk with installing updates in versions of MacOS X prior to Leopard was the possibility of disrupting prebinding. Prebinding is the process whereby library files are linked to executables, and problems can occur is applications are running (and in active use) during the installation of updates. If prebinding is disrupted, the system can fail to boot after an update, and the blue screen is a common symptom.
IF prebinding is a problem and you can't boot into safe mode, boot into single user mode (hold Ctrl-S during boot from hearing the chime) and then at the prompt, type 'sudo update_prebinding' (no quotes of course) and hit enter. Enter your admin password when requested, and sit back and wait for the command prompt to reappear, at which point the prebinding update is complete - it could take several minutes.
If that doesn't help, your initial post implies you do not have your original install disks - you may however need them, or a retail MacOS installer, because it may be necessary to perform an archive and install on the hard drive.
