Help, my mini REFUSES to shut down/restart

Hey guys.
I'm looking for some help figuring out what is making my mini hang on shut down.
My icons all dissappear and then I just see the osx backdrop. From there the system refuses to take any keyboard input, though I can move the mouse around. It will just stay there untill I hold the back power button down long enough to force a shutdown. When I reboot it says osx shut down unexpectedly. I try to look at the log by clicking on that option but the log never shows up. My mini is two weeks old and running Tiger.
Thanks for any help,
Kal

All the icons dissappear but the normal apple backscreen stays. It never gets to a black screen. No the pinwheel is not spinning. I no longer have any usb devices plugged in. I have a g4 1.42 mac mini. I did not import any data from a previous system.
I have tried to reinstall osx but due to it not being able to restart it will not complete he install. I have left it on the screen for hours to see if anything would happen, but nothing.
I think I may just return it and get another. It just seems too new to be having such a problem. I have put very little software on and it is all mainstream software that should have no problems.
Thanks for the help guys. If there is anything you guys can think of that
I may do please let me know.

Occassions where Mac Pro refuses to Shut Down/Restart

I have a Quad 2.8 Mac Pro (Early 2008) and have been frequently running into a problem where both Leopard (and now Snow Leopard) refuse to close my programs and shut my computer down when I ask it to.
This started roughly 4 months ago and started as just a minor nuisance. Since I use Boot Camp and run two operating systems I tend to restart often. I also always shut my machine down when I go to bed.
When I click shut down or restart the window for the logout countdown shows up. I go ahead and click to have it do it instantly and the machine will just sit there. Usually it will come up with an error saying a application refused to be shut down. What's odd is it is usually a program I don't even have open anymore. I can force quit every application I have open and it will still sit there.
Anyone seen this before? I don't even know where to begin.

Check on Activity Monitor if there is a process that is hanged or something... there is got to be a process that is not responding to the kill signal and you might have to force it to die for the shutdown to end...
once you find what process is hanging you can start working out why is it not closing and fix that problem...

Macbook refuses to shut down, restart or log out! :(

Hi,
Ive been having the troubles of not being able to turn off, restart or log out my Macbook after not shutting it down for a while ( like 1 or 2 weeks just kept putting it to sleep when it is not in use ). When I tried to shut down or restart it, the top bar and everything else went off leaving ma dock behind, it then just froze and kept saying that it cant shut down due to some random application have failed to quit! (e.g most usually firefox and Finder) eventhough i have already quit all my applications!
Does anybody know what the problem is? Is this usual if you dont shut down your macbook for a couple of weeks? Please advice!
Thank you very much,

Hi
Holding down the power button for about 10 seconds will force the macbook to turn off. This is only recommended as an emergency measure.
When you restart, I recommend you download either Onyx or Leopard Cache Cleaner and use it to step through the various maintenance activities it offers, including deleting all stored cache files.
You should perform this maintenance once a month or so (although you don't need to routinely clear out the cache files).

Satelite C660 refuses to shut down

Hi all,
hope someone can help, my laptop is refusing to shut down and I've no idea why.
Anyone have any suggestions?
Thanks

On this virtual way it is not easy to say why this happen but probably OS is blocked somehow.
What happen when you press shutdown button?
Maybe by some running process in the background.
Before you use option for shut down, stop some running software that you can find in notification area (notification icons).
If this will not help restart your notebook, do the same again and open task manager. Check if some of running processes has extremely high amount on memory. If yes stop it and try again.
Maybe playing a bit with background processes you will find out what is wrong there.

My mini won't shut down

when i try to shut down my mini, it keeps running. it gets to the point of logging out and i can see just the plain desktop picture. the fan is going, the monitor is on. it won't actually turn off. i've waited for 30 minutes. finally, i'll just unplug it (probably not good.)
any suggestions?
thank you.

Usually if the system refuses to shut down it's because a process is running that it can't force-quit, often related to an external device, but sometimes an installed application attempting to communicate.
Often the only way to resolve this is to power down by pressing and holding the power button for 5-10 seconds. This is not an elegant shutdown, particularly if the system is attempting to write to the hard drive in the hung activity, so on the next reboot, it is wise to run Disk Utility to verify the internal hard drive and ensure it hasn't developed a problem.
There's no simple way to troubleshoot this sort of problem since the devices connected to the system and the software in use all vary from system to system, but it's best to start by disconnecting all external devices other than keyboard mouse and screen and booting the system, then trying to shut down again before running any application. If that works fine, then it's a problem in an app or driver or external device. If not, it's in MacOS or hardware.
If the latter, it's probably a good starting point to repair permissions using Disk Utility, though sometimes a little more drastic spring-cleaning is needed using one of the general purpose utilities such as OnyX or YASU (YASU being my favorite for simplicity of use and the lack of options that can do more harm than good). Running all YASU tasks can help a range of behavioral problems. Another good utility to have on hand for these type of problems is Preferential Treatment, which can be run on both system and user levels to find damaged or corrupt properly list (plist) files which can also cause unpredictable behavior.
If the former, then it would help to know what devices and software you are using, but troubleshooting would typically need each to be connected/used individually to see at what point the system then began to have problems again.

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report — it will be very long and not helpful.

Mac wont shut down, restart or sleep - corrupted software update?

My Mac Pro (2007 - OSX 10.6.7) will no longer shut down, restart or sleep. When I try to shut down, it logs me out of my user account, shows the light blue screen, momentarily shows the Leopard space background screen, before showing the blue screen again, and finally returning to the login screen prompting for my user/password.
The only way to poweroff from this point is to hold down the power switch until it forces a power down. This issue has been present for the last two weeks or so ever since I did a Software Update containing a security update. Initially it just failed to perform that update, although after a few days it did do the update, seemingly by fluke. After that, the problem persisted and now there is a new update (Fonts) which again fails to update.
I have tried all of the following:
Power off Mac, unplug power and leave for a few seconds
Power on Mac holding down Ctr + Opt + R + P (resetting PRAM etc)
Boot up from install CD and perform Disk repair (it did find problems with the disk and repaired them)
Check and repair permissions
Delete Software Update related plists & caches from ~/Library and /Library
Still the problem persists. Examining the logs shows me this:

I can paste the crash report referred to in the logs if that would be helpful but for now will leave it out as it's huge and largely full of gobledygook.
I'm at my wits end now. I've always been very proud that in ~4 years of Mac ownership I've never had to reinstall OSX - something I used to do on an anual basis with Windows. My next step probably is a full reinstall, but I really do consider it a drastic step and a last resort.
Here's hoping that the Mac Support Community can help me out
Thanks in advance.

As a followup, upon the advice from someone else I created another user account (non admin) and logged in as that user. From that account I could successfully power down.
I'm still convinced the issue is related to Software Update as examining the logs showed none of the Software Update related entries as above:

Printing duplex with HP Officejet Pro 8600 causes windows 7 OS to shut down/restart

Why when printing duplex with my HP Officejet Pro 8600 printer it causes windows 7( 64-bit) to shut down/restart. Windows message is "Windows has recovered from an unexpected shutdown. I've ran HP Hardward Diag. Utility and Print and Scan Doctor which indicated everything is working properly with the printer. Ocassionaly I can print duplex without windows shutting down and restarting, but most of the time it creates issue with Windows causing it to stop and restart. Single sided printing seems to be fine. I've already oncehad windows to "Startup Repair" in which ccase I selected restore to a previous working point. Everything worked for awhile then a duplex printing session starting causing windows to shut down again. THanks for your assistance.

Yes, the updated USB 3.0 driver corrects the issue and should be installed.

Computer refuses to shut down/log off

I have a MacBook running the latest version of OS X and it's exhibiting some very peculiar behavior. As the title suggests, it refuses to shut off or allow users to log off, furthermore, some applications don't open or work properly. I ran a verify disk and permissions and they've come back with zero errors. What should be my next step in troubleshooting these issues?

Hello,
If your MacBook refuses to Shut Down, try this using the keyboard command for Force Quit. Command + Option + Esc. That will bring up the Force Quit window. If there any applications running, they will be listed there and your computer will not shut down until those processes stop.
As for applications not opening. Try locating and send their preference files to the Trash. I'll use iPhoto for an example. It's preference file looks like this:
com.apple.iphoto.plist It's located here: MacintoshHD/Users/YourName/Library/Preferences. In that Preferences folder are the .plist folders for the applications you use. Send the .plist files to the Trash. It's ok.. your MacBook will create new .plist files for you You will have to reset your preferences on these applications but considering they aren't opening anyway, this might help.
Also, if you haven't already done so get a good disk utility that you can run to clean out caches and log files and repair permissions all in one fell swoop. I use Onyx, it's free and it's here: http://www.apple.com/downloads/macosx/systemdiskutilities/onyx.html Download and install Onyx. Run the Maintenance and Cleaning scripts and reboot.
Hopefully something I've suggested will help.

Macbook Pro Won't Shut Down, Restart, or Logout after using Onyx.

Hi,
Earlier this week I found that my macbook wouldn't shutdown, restart, or logout from the finder menu (or any other menu, such as Onyx or Software Update). The only way I could get it to restart was through Terminal. I tried every solution, but nothing would fix it. After backing everything up, and doing a clean reinstall, everything was fine. Then, when I used Onyx, I tried to install the Archives Preference pane and the Processor Preference pane. The window just sort of hung there not responding - and finally I had to force quit Onyx. Now my system is back to not shutting down, restarting, or being able to log out again. The good thing is that I think I've isolated the problem. The bad thing is that I have no idea how to fix it. I tried uninstalling Onyx, but that did nothing. I've used Onyx regularly and have never had any issues, and I can't seem to find anyone else with this problem.
Can anyone help? I'm sorry if this is the wrong forum for this topic. If there is a better forum for it, let me know and I can repost.
Another problem that I'm having is when I open iTunes, the dock icon comes up for about a second and crashes. I tried completely reinstalling iTunes, but that hasn't worked. Perhaps I missed something? BTW - everything else is operating just fine (i.e. Quicktime, etc.)

HI and Welcome to Apple Discussions...
Run Disk Utility from your Mac install disc.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*
If you cannot boot from your install disc, try booting in Safe Mode
You do not need Onyx, especially not good for Snow Leoaprd. You can run cron tasks from the iStat Pro widget available here.

Mountain Lion won't sleep, shut down, restart, or log out.

Hi All,
After Mountain Lion my 2010 iMac 27" won't sleep, shut down, restart, or log out.
Basically most functionalities of clicking the apple icon are disabled - "About this Mac" doesn't work either.
Please help!
Before Apple fixes this, is there another way of putting my Mac to sleep or shut down?

Just adding another voice to the chorus. Since upgrading to Mountain Lion my computer will not sleep. The cursor freezes when I try to invoke sleep but the computer and monitor remain on. The cursor unfreezes when I tap the spacebar the way I would normally do to wake from sleep. Fortunately, shutdown, restart and logout function normally, so I guess I should count my blessings. This isn't my only problem with Mountain Lion, but I didn't want to muddy the waters on this thread with other issues.

Cannot shut down, restart, or log off iMac

I have an iMac with OS 10.5.2. I use the Virus Barrier virus protection program and have not had any problems with it. However, immediately after installing the latest Virus Barrier update, my computer began acting strangely.
Most importantly, since that time I have not been able to shut down, restart, or log off my computer. When I try to take any of these actions, I get the standard message box asking, for example, "Are you sure you want to shut down your computer now?" I click on "Shut down" and the desktop icons and the menu bar disappear but then nothing at all happens. Sometimes, after a while, I may get a message saying that the action "timed out." I then click on the Finder icon on the dock, and the desktop icons and menu bar reappear. I've tried force-quitting the Finder, but that did not work. Even if I manually shut off the power, when I turn it back on, the desktop immediately appears without the usual beep and without going through the normal startup procedures. It seems that even when I turn off the power manually, the computer itself does not actually shut down.
Additionally, my screen saver no longer works. Although I have it set to come on automatically, it never does.
I contacted Virus Barrier support which advised me to uninstall the program. I did, but that did not help the problem. I've tried "Repair Disk Permissions" in the Disk Utility application, but that did not help either.
Apart from the above, I still seem to be able to use the programs on my computer with no problem.
Does anyone have any idea what is causing this problem and what I can do about it?
Thank you.

DO NOT JUST PULL THE PLUG! Press and hold the power button until it shuts down fully. This can take several seconds. Once you are sure the fans are off, click the mouse a couple of times to make sure there is no response, then you can pull the plug, to be sure.
I suggest that you then start up in Safe Mode by holding the Shift key as soon as you hear the chime. The OS should start in the normal fashion, except you will see a Safe Boot legend.
Once you've logged in, bin the Finder .plist as suggest, and I'm make sure that all the Virus Barrier files are well and truly gone as well. Don't forget to check /Library/StartupItems and ~/Library/StartupItems. Once you reboot, things should be back to normal.
As suggested, AV programs are pretty much a waste of CPU on a Mac. If you really must have one, I recommend ClamXAV. Apart from anything else, it's free.

Mac won't allow log in, shut down, restart or sleep

This morning I started my Mac but it wouldn't allow me to log in, shut down, sleep, restart or anything else. I phoned for help and was told to shut down by holding the button on the back. Then unplug Mac from the power source and leave for a couple of minutes. Reconnect plug into socket and re-start using the button on back. This fixed it! Apparently, static power can remain in the system sometimes, causing this kind of problem. You need to disconnect from the power source and wait to allow all the static to drain from system, before re-connecting. Hope this helps.

As a followup, upon the advice from someone else I created another user account (non admin) and logged in as that user. From that account I could successfully power down.

Toshiba Qosmio X500-12N Shuts Down/Restarts for no reason

As the title says. This started happening some months now. It always happens when I play games, watch Twitch.tv streams or watch XBMC. I took my laptop to the local Toshiba store and told me that the fans were faulty and needed to be changed. They wanted to charge me 300 dollars for it so I decided to order a brand new heatsink with fans included from the internet for 100 dollars. I changed the whole heatsink with a brand new one and it keeps shutting down. They also said that there might be a problem with the hard drivers and that's what causing the problem. What do you guys think is the problem?

Hi KyriakosMenelaou,
I experience this issue before when im playing LOL [Legends of League] my laptop shuts down/restarts for no reason while im playing the game.
I tried to install the latest directX support for my video graphics and update the latest version of my video graphics.
Patch the latest video graphics driver support for the game. If you are using ATI or NVIDIA you can directly go the this website to download the latest video driver.
Until now it works perfectly fine w/o a problem.
But what if the issue still persist?
I might say that you need to do system recovery.
But what if the issue still persist?
I might say that you need to replace you internet hdd.
Hope this will work for you. ^_^
BTW IF YOU THINK IT HELPS ALOT. PLEASE DONT BE AFRAID TO CLICK KUDOS star ^_^
