System won't start up after Software Update problem

I turned on the computer and ran Software Update. iTunes and others successfully updated, but there was a problem with the Quicktime update. The system required a restart to complete installations, so I did. The circle of lines was running around and around, but then blank screen and frozen cursor. I attempted to power down and restart, but to no avail. I restarted holding the Shift key and it loads up. I repaired priveledges and restarted. Still will not start up. Please, help me.

You say that "it loads up" when you start with the shift key down. I assume that you mean the system boots up okay. If so, you are successfully starting up with a Safe Boot.
According to Apple's KB article on What is Safe Boot, Safe Mode?, the Safe Boot is doing the following:
- It forces a directory check of the startup volume.
- It loads only required kernel extensions (some of the items in /System/Library/Extensions).
- It runs only Apple-installed startup items (some of the items in /Library/StartupItems and /System/Library/StartupItems).
The main goal of the Safe Boot is to repair the disk (filesystem) and to disable a variety of 3rd party extensions and startup items in the 3 folders listed here. Since you cannot startup normally after the Safe Boot, it seems that the disk repair did not fix the problem. So, most likely, you have some item in one of the 3 folders that is causing you trouble. Sometimes a 3rd party item is not compatible with an Apple upgrade and startup problems can occur after the upgrade.
So, a troubleshooting strategy would be to start back up in Safe Mode and then to inspect these folder for some item that looks suspicious to you. One approach is to look at 3rd party items that have been recently installed. If you find something that you suspect, drag it onto the desktop and then try to restart normally. If you are able to reboot normally, you have found the problem.
I hope this helps.

Why won't my system won't suut down after software update?

why won't my system won't suut down after software update?

That's an annoying issue. Disconnect all USB devices such as Pen drives and external HDDs before doing the update.

Won't start up after software update

I have a PB G4 titanium 1ghz running 10.4.11. Just ran the latest software update which installed the latest security update, iTunes and QuickTime. At the end of the process the screen went black so I powered down by holding down the power button. Tried to restart and it just sticks on the grey apple screen.
Because of the common issues with the optical drive on these pb's I can't run anything off a disc to get it going. Don't have a bootable hard drive either. Feeling a bit stuck so wondered if anyone has any ideas for me.

Tough without the Tiger Disk problems, but try fsck...
To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup. Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt, type /sbin/fsck -fy
(SPACE between fsck AND -fy important)
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found: 
The volume (nameofvolume) appears to be OK  If fsck found issues and has altered, repaired, or fixed anything, it will display this message: *** FILE SYSTEM WAS MODIFIED ***   Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.

Then Safe Boot, (holding Shift key down at bootup), & use Disk Utility from there to Repair Permissions, reboot once more.

Hey Stheus3,
Thanks for the question, I understand how frustrating this may be. It sounds like the update process may have been interrupted, and to resolve the issue, we’ll need to restore your device in recovery mode with iTunes:

HT201262 No start up after software update?

I have been unable to restart me computer after a software update (White screen/apple logo/spinning wheel continuously). I have tried to start up in safe mode (holding down shift key) but it hasn't worked. Any ideas?
Thanks

General advice on updating:
It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
So before you do anything else:
If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
Turn off sleep mode for both screen and hard disk.
Disconnect all peripherals except your keyboard and mouse.
1. Repair Permissions (in Disk Utility)
2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
3. Download the correct version of the COMBO update from the Apple download site. If your car runs on gasoline you would not want to fill the tank with diesel, so don’t try to install the PPC updater on an Intel Mac!
The 10.4.11 Combo Updater for PPC Macs is here: http://support.apple.com/kb/DL170
And for Intel Macs here: http://support.apple.com/kb/DL172
If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
Full details about the 10.4.11 update here: http://support.apple.com/kb/TA24901?viewlocale=en_US
More information on using Software Updater here:
http://support.apple.com/kb/TA24901?viewlocale=en_US
Using the Combo updater ensures that all system files changed since the original 10.4.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.4.10 to 10.4.11. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
Now proceed as follows:
4. Close all applications and turn off energy saving and screensaver.
5. Unplug all peripherals except your keyboard and mouse.
6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
8. Once your Mac is awake, repair permissions again, and you should be good to go!
If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious!
9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a weeks or two while you regularly check their websites for updates. This applies particularly to plug-ins for Safari 3.
N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
Lastly, Apple's own article on the subject of Software Update may also be useful reading:
http://docs.info.apple.com/article.html?artnum=106695
[b]If you are updating Safari (or just have):[/b]
Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If you have installed an OS update and Safari is crashing, the very [i]first[/i] thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari. Remember: Tiger up to 10.4.10 used Safari 2.0.4 or, if you downloaded it, Safari 3.0.3 beta. Safari 10.4.11 used Safari 3.0.4 which was [i]not[/i] a beta. If Safari 3.1.2 on 10.4.11 is not the fastest browser you have ever used, then something is wrong!
Moreover, trying to revert to Safari 3.0.4 (or worse still, version 2) when running 10.4.11 or 10.5 can have repercussions, as Safari 3.1.1 uses a completely different webkit on which other applications like iChat, Mail and Dashboard Widgets etc also rely, and may entail you having to reinstall an earlier operating system.
[b][i]Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party ad-on.[/b][/i] Two such add-on that have been frequently mentioned here for causing such problems are Piclens and Pithhelmet. If you have them, trash them.
Additional tips on software installation here:
http://docs.info.apple.com/article.html?artnum=106692
To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
Again, the advice is to remove all Input Managers from the following directories:
/Library/InputManagers
~/Library/InputManagers
especially prior to system updates (they can always be added back one-by-one later).

Computer won't turn on after Software Updates

About a month ago my computer had some Windows Updates, I installed them as per usual, it asked to restart the computer, but once it shut down, it wouldn't turn back on. I tried a few different outlets, no change (all of these outlets work). I left it unplugged overnight (8-10 hours) and when I plugged it in the following morning, it turned on and was fine until this past weekend.
Again, there were more updates, this time it was for AVG and when it went to restart, it again wouldn't turn on. I tried the same thing, and it's not coming on. The light by the power button will flash when I push the button, real quick, but nothing. The light in the back shows power going to it. I believe my computer is in the HP All-in-One 200 family, but I'm not sure which one (and though I've registered it, it doesn't tell me on my account which one I have, or I just can't find it).
Is the motherboard done, maybe the RAM, or the HDD? I don't have the money to get a new computer at the moment so I really want to try and get a few more years out of this one (I have had it for 5 years). Any thoughts would be appreciated. Thanks.

[SOLVED] UEFI-System doesn't start anymore after rEFInd update

Hi there,
got some problem with my UEFI system after todays update of refind-efi: Arch doesn't boot anymore
What have I done:
At first I did a
$ sudo pacman -Syu
During the update I was presented with the usual information concerning copying some files from /usr/lib/refind/*. So I did this:
$ sudo cp /usr/lib/refind/refind_x64.efi /boot/efi/EFI/refind/refind_x64.efi
Than I did:
$ sudo cp /usr/lib/refind/config/refind.conf /boot/efi/EFI/refind/refind.conf
$ sudo cp -r /usr/share/refind/icons /boot/efi/EFI/refind/icons
After that I rebooted my computer and was presented with an "Asrock" writing that doesn't change to the rEFInd-screen as it should.
Question: What can I do now? (And what did I wrong?)

Hi Rod,
thanks for your quick answer !
Ok, you write:
srs5694 wrote:
The 0.6.3 package changes the name of the rEFInd binary from refindx64.efi to refind_x64.efi. This is done because the official rEFInd release uses the latter name, and it includes support scripts that work correctly only if that name is used. Thus, if you deleted your old binary and copied the new one in place without renaming it to the old name, it would stop working, since the NVRAM entry would still point to the old name. There are two solutions:
Rename the new binary to the old name (refindx64.efi). If you do this, you'll need to keep doing it in the future or eventually do the next thing. Also, this might not work if your firmware has "helpfully" removed the existing entry. Thus, the next option is probably better...
Use efibootmgr to add a new entry for the new name. The Arch wiki has details on this here and probably elsewhere, too.
Jepp, I've seen the new name "refind_x64.efi". During my attempt to perform a proper install I did what you assume in your first solution - renaming the new binary to the old name (refindx64.efi).
After that my system didn't reboot ...
After that I booted from my USB stick with which I've installed my Arch system. I mounted my system partitions to /mnt, loaded the efivars module and arch-chrooted into the system. From there I copied the new binary from /usr/lib/refind/refind_x64.efi to /boot/efi/EFI/refind/refind_x64.efi and did this:
# efibootmgr -c -g -d /dev/sda -p 1 -w -L "rEFInd" -l '\EFI\refind\refind_x64.efi'
/boot/efi is mounted to /dev/sda1
But even after I did this a reboot only led to the well known green "Asrock" writing - no rEFInd appeared
Using the efi shell I can see that the boot entries seem to be okay.
srs5694 wrote:rEFInd 0.6.3 has a known bug that causes it to crash on some systems. Upgrading to 0.6.4 may be necessary if you're affected by this bug. The usual symptom is a system hang, though, not a return to the firmware menu, so I suspect this isn't the problem. If it is, you can grab the official non-Arch rEFInd package and copy the refind_x64.efi file from it over the one on your ESP.
Hm, seems as if I have to try this ...

Tiger won't start up after massive update from Apple.

Greetings Apple Discussions:
I have been using Tiger for a few months. I have my main start up on a 250 and back ups on other HDs. I updated some Apple apps from the Apple Software Update program: Apps like Quicktime, iPod, etc. The computer went into restart and never restarted—from the main start up HD. It just hangs on the Apple logo. I have to start up from other HDs. Is there something I can do to repair the main HD. I have most of the updates on it since cloning a copy of it a few months ago. I can access its contents.
Thank you.
Aubrey

Hi, Aubrey.
1. I suggest you begin troubleshooting using the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
2. An errant Startup or Login Item maybe the cause. In this case, it may be a Startup Item or perhaps a third-party kernel extension. My "Troubleshooting Startup and Login Items" FAQ can help you pin that down if an errant Startup Item is causing the problem.
3. It may be that the update did not install correctly. For example, you may have had directory corruption present before you attempted to install the update. If that's the case, or if step 1 above finds issues, even if they are corrected, then an Archive and Install would be in order. See my "General advice on performing an Archive and Install" FAQ. Perform the steps therein in the specified order.
Before installing future software updates, you may wish to consider the advice in my "Installing Software Updates" FAQ. Taking the steps therein before installing an update often helps avert problems and gives you a fallback position in case trouble arises.
Good luck!

LEAVE it connected to the wall outlet charger (not the USB > PC charger).
Leave it connected for 24 hours... every 3-5 hours, press and hold the power button only for about 20 seconds. Eventually it will boot on up, but first must reach a certain charge level.
You will see the blinking red and perhaps yellowish LED light, and perhaps a symbol on screen of "no battery". That means the battery is drained, but it must reach a certain charge before powering on.

ITunes won't start up after recent update.

I recently updated my iTunes software a few days ago, to the current 10.6v (64-bit for Windows), and ever since the update, I haven't been able to open up the program at all. I can double-click the icon numerous times and my cursor will show the timer as if it's about to open, but nothing happens.
I can still plug in my iPod Touch (4th Generation, I believe) and it'll charge just fine. However, sync-up is impossible since the program won't run in the first place.
I have already tried uninstalling iTunes and reinstalling it, and so far, there are no results. Program still won't run.

I've done the first few steps successfully, but I run into a problem when I'm required to type in "C:\Program Data\Apple Computer\iTunes\SC Info" into the address bar. When typed in, I recieve an error message that says, "Windows can't find C:\Program Data\Apple Computer\iTunes\SC Info. Check the spelling and try again." I've directly copy and pasted the exact code in from the help page and it won't work.

Win7 BootCamp won't start up after Windows Update

I been using Win7 with Bootcamp for over 8 months now and no problem but last night I shut down with a windows update and this morning it can not start up at all. I just get a black screen. I can select and enter my OSX drive no problem, even access the Boot Volume and copy files off it to my Mac partition also. Holding option key on startup shows my two dirves also. Is there anyway to revert back to old version of Win7 on startup or do I have to reinstall everything again?

Did you let the update complete? or shutdown while some of the update was still to be completed. A lot of it is done and completed after a restart.
Start getting into making sure you have free space, using restore points (you may need to boot from the DVD). You can also rollback an udpate to driver or uninstall.
There are always and will be 2nd Tues of the month critical security update in two days. The only Windows Update I've seen are to Microsoft Security Essentials. Maybe 3rd party issue?
I use CCleaner 3.0 on a daily basis to clean out temp files.
(you are running Windows, Boot Camp, no, that was/is drivers and partitioning tool, nothing else). Do you use a VM also? makes it sound like you might. Updates are best done running Windows natively, that is about as close as I can make it to what people keep referring to as "running Windows on Boot Camp" is just Windows running, not as a guest OS VM.
