Ran todays software update. All was normal but got suck on a blue screen with spinning icon.
Eventually, 15 minutes or so, screen went black.

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?

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.
Mac OS X: Starting up in Safe Mode Mac
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

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.

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.

Hi,
I have the old MacBook Pro. Upgraded to Mountain Lion which completely wrecked the system. So downgraded to Snow Leopard.
Then 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

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.

When I click on Firefox it opens with a box that says "Foxfire is installing your updates and will start in a few moments-. " then it says "Software Update Failed (in blue) with an exclamation mark inside a yellow triangle) The update could not be install

When I click on Firefox the first time it says "Foxfire is installing your updates and will start in a few moments…. (with a green bar)" then it says "Software Update Failed (in blue) with an exclamation mark inside a yellow triangle)
The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again." When I click the ok, Firefox opens up. If I open another Firefox window with the previous one still running, it doesn't give me any of these messages, it just opens normally.
== This happened ==
Every time Firefox opened

If you can't install on top of the current installation then you need to delete or rename the current Firefox program folder to do a clean install.
It is possible that your security software is using or locking files, so you can try to temporarily disable that software during the installation.

Well I am having the same issue and I had not had to worry about getting a "licensed charger." The poster who responded offered not real insite and was rude to boot. I am also looking for the fix on this . My iphone will not even charge now on any charger. What the heck. I am not trying to treaten anyone either when I say I am frustrated with my iphone which in my case I have only had for a few months. I have already sent one in to be replaced and this is my second one. I have had troubles since the update GRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR .

Be patient. Apple just released IOS 6.1 and their servers are inundated with downloads. The network link between you and Apple may also have some undisclosed throughput or latency issues.
I just updated to IOS 6.1 and it took much longer than I expected.

Software Update stuck: "Moving files into place"

Software Update stuck. In OS C Lion (10.7.4) I ran Software Update on 25-Jul-2012 (The day when OS X Mountain Lion was released). Software Update had 5 updates, such as Safari 6.0, Remote Desktop, iPhoto (?). Software update gets about 95% done, based on the progress bar. Then it hangs... for hours. I finally had to force-Quit Software Update. Rebooted. Tried again. Same problem. Rebooted and rest the PRAM (command-option-P-R) at start-up. Ran Software Update and had the same problem. Software Update hangs while "Moving files into place." Has anyone else seen this problem and know how to get it to work?

I discovered that if I selected only one update at a time to install, all but one installed (i.e., Remote Desktop, Safari 6, and iWork update). The one update that did not install was the iPhoto update. I had left the install to run overnight (about 7 hours). Console log for /var/log/install.log when installing iPhoto update follows:

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.
