10.6.8 update stuck on blue screen... 4 hours and counting

Upon selecting automatic software update my system seems stuck on blue screen with spinning grey gear. How long should I tolerate this (going on 4 hours now) before attempting to do something?
I can access the hard drive of this computer from others on my local network and am able to copy files from it. I'm wondering if I should try to grab all that is valuable to me before anything worse happens.
Advise?

If your data is not backed up copy any important documents you can from your Mac's startup drive.
Once you are done copying your data, use the power switch to turn off your Mac and disconnect everything except a wired keyboard/mouse and monitor. Start up in safe mode by holding the shift key down right after you hear the startup chime. Keep holding down the shift key until you see the Apple Logo and spinning gear.

OS X: What is Safe Boot, Safe Mode?
Safe mode will do some maintenance routines and checks/repairs the disk if needed so it will take quite a lot longer than normal to boot. Once your Mac boots restart normally. It will take a little longer than normal to boot but not as long as booting in safe mode.
If things don't work as expected install the Mac OS X 10.6.8 Update Combo

HT5132 I've already dealt with my MobileMe Albums, and now Aperture 3.3.1 is stuck on moving them -- 28 hours and counting. How do I stop it?

I've already dealt with my MobileMe Albums, and now Aperture 3.3.1 is stuck on moving them -- 28 hours and counting. How do I stop it?

Quit Aperture
Then disconnect from internet (WiFi, Ethernet, etc.)
Launch Aperture again.
In the Aperture Preferences Web Tab remove MobileMe.
After that you can connect again to to the Internet.
Probably the "Quit" button does not work. Then try to quit using the Terminal to avoid "Force Quit":
Launch the Terminal (from Applications > Utilities) and enter
killalll Aperture
If this does not work, use "Force Quit".
See here why to avoid force quitting:
If Aperture is unresponsive, how to avoid force quitting?

Try performing a hard reset. When performing a hard reset please note remove any and all USB devices. Disconnect all non-essential devices.It should continue where it left off.

Installed OS X Tiger / Security Update / Stuck at Blue Screen

Hello,
I need help. This is for one of the computers at work. We are doing a system overhaul and I needed to upgrade the G5 PowerPC. We bought the Tiger install disk. I backed up all the files to an external drive and decided to just to a complete wipe of the hard drive. I chose the Erase and Install option.
No problems. I did not install any other software. I did not change any settings. The only thing that I did was run the software updates. There were some security updates and one for quicktime and the one the OS X and a few others.
It was after the update that I begin to have problems. I was having some freeze up errors yesterday and then I did the whole process over again. So I thought it was done and then this morning I come in and turn it on and it gets stuck at the blue screen with the pointer. I ran Disk Utility and there are no bad sectors. It repaired some permissions but still no fix. I checked the login startup items and there is nothing there except an iTunes helper application. Like I said, I have installed nothing else except the update. I ran the hardware test and everything is good.
I am going to Erase and Install again. But I need to know if there is something wrong with the updates. A few people seem to be pointing fingers at Quicktime. But I don't want to install updates without knowing what is going on. Can someone help me. Thanks.

Hi Jay,
I don't know if I can help but I'm also going through Tiger installation problems on a G4. But first:
What version of OS X was on the G5 when you began the upgrade? Panther?
Was it the retail DVD in the black and silver box? This version will install on any Mac G3, G4 or G5. Or did it come from another Mac? Non native installs can cause problems.
I backed up all the files to an external drive and decided to just to a complete wipe of the hard drive. I chose the Erase and Install option. <--
If an earlier version of OS X was already on it, it would've been better to do an Archive & Install, which would preserve your files and settings. A&I is in the Options when the button is clicked below the Erase and Install icon. It sounds like your finder can't find the system you installed. Erasing may have done this. The beauty of Archive & Install is that, it installs a fresh copy of OS X on a preserved software that have left a warm bed for them not an empty cold bed system. Anyway that's my take on it. The best way to "Erase and Install" is with the install DVD by booting up from it. Hold down the C key while you boot up. Then go to Disk Utilities in the menu and click on it and follow the steps to Erase and Install. Then follow the steps to place a new system on the hard drive. But go with Archive & Install. It works.
I am going to Erase and Install again. But I need to know if there is something wrong with the updates. <--
Others have reported problems after updates. Were they Combo updates? The software pages have smaller versions of Tiger on the Tiger getting started pages in the Apple website. But IMO it's not the updates. Your system needs them and will update what's current. Like I said I don't know for sure but Erase and Install may lie at the core of the problem. If possible try to get a version of Panther (10.3) and go from there. AND try to find out what version of OS X was on the G5 when you took it over. But to be sure, if you can, call a certified Mac dealership and see if they can help by answering questions. He may ask you if you have Apple Care their insurance program. If the warranty is still good you can get some repair work done if necessary.
Report back after your trip.

I'm livid about Apple putting out a software update that could wreck a system like this.
Every software update is capable of this if there are problems with the Mac that haven't been corrected before the update is applied. It is the Mac itself that performs the update so if it has problems, you cannot expect it to perform normally, especially during an update.
There is only one even potentially foolproof way to avoid this, & that is to make it impossible for the Mac to either obtain or apply any updates at all. For what should be obvious reasons, this method hasn't been used for about 45 years with any personal computer.
I suppose it will be easy to restore everything with Time Machine (a new experience to look forward to?). But if we weren't using Time Machine or something else to back up the iMac's hard drive, this would have ruined our lives.
If losing the data on your Mac would ruin your life, you have no business ever even turning it on without a proven, reliable backup strategy. Macs are machines. Machines can & do break. What more do you need to know?

Hi, Hi, Hi I have the old MacBook Pro. Upgraded to Mountain Lion which completely wrecked the system. So downgraded to Snow Leopard. The updated the combo update. Now stuck on blue screen at start-up. Need help. Greatly appreciated. Thank you.

Downgrade Lion/Mountain Lion to Snow Leopard
1. 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.
2. After DU loads select your hard drive (this is the entry with the
      mfgr.'s ID and size) from the left side list. Note the SMART status
      of the drive in DU's status area. If it does not say "Verified" then
      the drive is failing or has failed and will need replacing. SMART
      info will not be reported on external drives. Otherwise, click on
      the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions
      from the drop down menu to one. Set the format type to Mac OS
      Extended (Journaled.) Click on the Options button, set the
      partition scheme to GUID then click on the OK button. Click on
      the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

10.5.3 won't install... stuck in blue screen loop

I chose to install it from software update. It told me to restart. I did.
I got hung up on a blue screen loop.
But no error messages or anything.
I had to hard reset.
Then started up fine- but system profiler shows I'm still 10.5.2.
And software update still shows the update as "downloaded".
If I click "install" it immediately asks me to reboot, and sticks in the blue screen loop again.
I have done this three times now.
If I choose restart from the apple menu- same thing.
So I decided to shut down- can't shut down. Get stuck in the looping blue screen.
So it seems like something is gumming up the shut down process. I've heard of startup items making things freeze- can the same thing happen when shutting down?
Not sure what the issue is.
The other people posting problems seem to be getting error messages, etc.
I am going to try to repair permissions, and if that doesn't work maybe I'll try the standalone installer- but why is this happening? this is like a 2 week old MBA with next-to-no third party stuff installed on it... what could be corrupted already?
fortunately I have backups if worse comes to worse...
Any other tips/thoughts?
Thanks!

You could try, it's been known to sort system issues because it's fuller than the incremental "delta" update, so it should overwrite any files that are damaged or missing.
Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
But if you can't boot into Safe Mode something is amiss*. Since, you are able to use your system (not stuck on blue screen, try this first:
Go to System Preferences >> Accounts >> Login Items and remove them. Boot normally and test. If not go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving ~(yourHome)/Library/Fonts to your desktop and restarting.
*EDIT: You do have to hold the shift key for Safe Boot until you see the spinning gear, just in case you didn't do that.

GE60 0NC-622UK laptop is stuck on Blue Screen can't login! please help..

Had this laptop for just one month, before it's all good. Windows 8 64bit.
In last two days, the mouse and touchpad became dysfunctional occasionally, able to move the pointer but just could't click on anything regardless of left or right, e.g. choose or open new. It would be working after logoff/relogin and reboot, but same problem still came up randomly.
Last night, I did the same thing to reboot the laptop after had the pointer dysfunction, but then it displayed a blue screen before the login with a error called 'System Thread Exception Not Handled', and then just stayed on this page would't reboot automatically (waited for 30 mins), so it left me no choice to shut it down by pressing power on/off button manually, afterwards with couple of times rebooting, it just kept going into this same blue screen and could't get into the system...Sometimes it would automatically start diagnosing before blue screen, ask me to restore or repair, but none of them fixed the problem, repeatedly stuck on blue screen every time...
And I don't have any windows 8 dvd, delivered box only has one for drivers and manual book.. so boot from dvd is not possible..
p.s. sorry about my english if caused confusion
thanks..

Try starting Windows 8 in Safe Mode, its kinda difficult in Windows 8 to do you have to be very precise when doing it, right as the system boots you need to start spamming F8 sometimes you have to do Shift+F8.
You may want to disable fast boot in the BIOS so you have some time to get ready to hit the buttons, once you get the boot menu up try Start Up Repair first and see if it fixes anything then try booting, if noting then try safe mode and un-do anything you have done to the system recently.
Let me know how this goes.
Really appreciated your help!
I get into troubleshooting page by pressing F3 when laptop was booting up, and changed start up with Safe mode which works..I've done many things in Safe mode, like updated drivers, run anti-virus program, deleted recent installed software, and then somehow the blue screen error was gone after reboot...It seems one of them must be the cause for that problem.
Anyway, my laptop is working properly now, thanks a lot, if error happens again in future i might still need some help

Hi You may have a hardware fault take ipad to Apple Store. Ring then first to make an Appointment take box and you purchase paperwork they may give you A replacement. Before you do that Try a Reboot hold down power button & menu button hold both down until you see Apple Logo you may need to hold down for up to 30 Seconds But you may need to do this more than once. If it doesn't work take back to Apple Store. Cheers Brian

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.

MacBook won't start, stuck on blue screen

My MacBook is stuck on blue screen... forever....
MacBook info:
13.3in, 2.0GHz Intel Core2 Duo, 120GB HD, 2X1GB RAM with Leopard
MacBook was running great until last night... My screen got frozen while browsing, and force quit did not work. So I used power button to turned it off. After that, my MacBook won't boot up anymore... gray screen for about 3min, apple icon screen for 15min, then stuck on blue screen.
I think I've tried everything in here..
http://support.apple.com/kb/TS2570
The only command that I was able to use was "Reset the NVRAM / PRAM", but no change there...
I tried install DVD (came with the MacBook), but I cannot boot with DVD with C button and now the install DVD is stuck....
Is there any way to fix this? My warranty expired already, and I am trying to do everything before taking this to the store...
Thank you.

Thanks Eric.
I have tried that before, but I gave an another try. I held the option button longer this time, until I saw the apple icon. Then cd (DVD?) image came on, so I clicked on it. But after apple icon went away (10 min?), my macbook is again stuck on blue screen. I only saw cd image, and did not see any other drives... Is that a bad sign?
Thanks,

G5 stuck on blue screen at set up point?

I've read other listings and they all have tried everything they know. I know nothing except to turn the computer on and off. Last night it worked then this morning it is jusst stuck at this start up point. I held in the button and turned it off and on again, got stuck at blue screen point again. I unplugged everything and still stuck? Please advise as I just spent hundreds adding this G5 to our system of g4's throughout the house and are looking forward to using it.
Thank You

Have you tried starting from your install disc and using Disk Utility?
1. Insert the Mac OS X Install disc that came with your computer, 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. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Please post back with results,
