IMacs almost always refuse to shut down

Hi,
I have at home 2 iMacs and a MacBookPro, all running the latest OS.
My 2 imacs have big trouble shutting down. Sometimes they do, but mostly they don't.
Especially the most recent one (ALU) causes problems.
I shut down, nothing really happens and after a while i get the message (for instance) "iCal refuses to shut down", while iCal wasn't even running anymore. I click ok, re-shut down, and after a while he tells me it's iTunes that refuses to shut down. Same thing, iTunes wasn't even running.
This is driving me crazy... my iMac hasn't shut down normally for more than a week now...

They're connected to the same router which never shuts down. There was never a problem before with this.
Both of them have a seperate LaCie disk that i use as a backup with time machine.
I don't know what NAS is. There's no central location for iTunes or iCal. The errors can mention other programs as well (excel, ...).
I do have two MobileMe accounts (family and workrelated).

Fails or refuses to shut down.

I have a new Macbook after working with Macs for years.
At the end of the day I try to shut down my Mac book. It seems to shut down.
When I get up in the morning, it is up and running.
It is either not shutting down or re starting without a command to re start.
It seems to do both.
when I searched the forum, there were many hits on shutting down when people did not want the Mac to shut down. But this problem is refusing to shut down or failing to shut down.
Any ideas?

When you select "Shut Down" from the Apple Menu, wait for the screen to go completely black and make sure that the fan has stopped running. Sometimes it can take awhile to completely shut down.
Also, try resetting your PMU.

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.

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.

HT1199 my computer displays grey screen and apple logo for 10 minutes or more during start up and shut down. sometimes it refuses to shut down . this issues started after installing OS lion. what do i do?

I don't think it's exactly an incomplete installation brody, but most likely in-correct permissions somewhere along the line that either happened, or became magnified during the upgrade. Also, it could be corruption as well.
First thing to do, is boot up holding down Shift key to do a safe-boot so we an clean up any corrupted OS caches, after that do another reboot, but go to the Lion recovery, and scan the HD for errors, repair any if you find them, and then try to do a Repair Permissions job.
That should fix the issue, if not, we can start doing a PRAM reset and SMC for good measure.

I have Imac, and I can't shut down it at all

I have Imac, and I can't shut down it at all

If you've already chosen Shut Down from the Apple menu and it's hanging there indefinitely, press and hold the power button until it shuts off.

IMac 21,5": Hangs or shuts down

Hello all!
My iMac 21,5" hangs or shuts down once in a while.
It also gets really slow, especially when saving a file in Adobe Illustrator CS6 and than switching to the finder.
I hope somebody can help me.
Many thanks.

That panic was not caused by third-party software. If the problem is recurrent, the possibilities are:
A stale or corrupt kernel cache
A damaged OS X installation
A fault in a peripheral device, if any
Corrupt non-volatile memory (NVRAM)
An internal hardware fault (including incompatible memory)
An obscure bug in OS X
You may already have ruled out some of these.
Rule out #1 by booting in safe mode and then rebooting as usual. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
You can rule out #2 and #3 by reinstalling the OS and testing with non-essential peripherals disconnected and aftermarket expansion cards removed, if applicable. Sometimes a clean reinstallation (after erasing the startup volume) may solve a problem that isn't solved by reinstalling in place, without erasing.
Corrupt NVRAM, which rarely causes panics, can be ruled out by resetting it.
If your model has user-replaceable memory, and you've upgraded the memory modules, reinstall the original memory and see whether there's any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol. Aftermarket memory must exactly match the technical specifications for your model.
The Apple Hardware Test or Apple Diagnostics, though generally unreliable, will sometimes detect a fault. A negative test can't be depended on. Run the extended version of the test.
In the category of obscure bugs, reports suggest that FileVault may trigger kernel traps under some unknown conditions. Most, though not all, of these reports seem to involve booting from an aftermarket SSD. If those conditions apply to you, try deactivating FileVault.
Connecting more than one display is another reported trigger for OS X bugs.
If your system is not fully up to date, running Software Update might get you a bug fix.
In rare cases, a malformed network packet from a defective router or other network device can cause panics. Such packets could also be sent deliberately by a skillful attacker. This possibility is something to consider if you run a public server that might be the target of such an attack.
If none of the above applies, make a "Genius" appointment at an Apple Store to have the machine tested. You may have to leave it there for several days. There isn't much point in doing this unless you can reproduce the panic, or if you can't, it happens often enough that it's likely to be repeated at the store. Otherwise you may be told that nothing is wrong.
Print the first page of the panic report and bring it with you.

Hi guys I'm really in need of some help. I have an IMac I3 for a while now I've been having a problem of my machine refusing it shut down , it goes to a blue screen with a spinning wheel but doesn't shut down. And now won't boot from install DvD

Please some one help me ...
A) my mac won't shut down with external HD connected (if it's been used)
B) there are disk permissions that can't be fixed SUID stuff ..
C) I have now verified the Mac HD and it tells me it's corrupt in bold red writing and to start up from install DVD
D) it won't boot from DVD so I cannot run the repair , initially the machine was spitting it out on start up , now it appears to be attempting to boot off DVD , well it sounds like it is .... BUT it's hanging with the Mac Logo and a wheel ... For um .... 30min now...
E) weirdly when OSX is booted off the hard drive , it won't recognise the Install DvD or the applications one... It just spits them out....
I had an old PPC 17" and it was a beaut .... Never had a single problem with it ...
I bought this one December 2010 and it's been nothing but issues for a computer in excess of £1000 I'm extremely disappointed ... And weirdly the shutting down issue started when it was a week out of warrantee ... I feel conned and am almost at the point of throwing it at a wall and buying a PC

Ok so I've done what you said and this is what it's come back ....
I don't know that these are the errors , but they're the things which don't look right ...
Throughout the shut down there is a recurring line ;
It says ;
Com.apple.launchd 1 0x100600e70.anonymous.unmount 301 PID still valid
Then there are 2 more which I think are related ;
Com.apple.securityd 29 PID job has I overstayed its welcome , forcing removal.
Then the same with fseventd 48 and diskarbitrationd 13
Oh and on Launchd1 : System : stray anonymous job at shut down : PID 301 PPID13 PGID 13 unmount...
Then the last process says "about to call: reboot (RB_AUTOBOOT).
Continuing...
And stops ...
Hope this means something to you ... Thanks again for your help so far :-)

Imac: Better to sleep or shut down?

Does anyone know if its better to leave the computer in sleep mode or to shut it down completely? I was told by my friend that its better for the hardware if i leave it in sleep mode. Is this true?

It's not likely to make a huge difference.
The advice stems from the observation that when turning on a computer there's a greater jump in voltage across the electronic components and it's under these sudden voltage changes that electronic components experience the most wear and highest potential for failure.
In fact, that's generally true. However, with contemporary computer designs, particularly in iMacs where the current is generally quite low and power supplies pretty decent, the difference between going from the sleep-to-wake state is not substantially different than going from the off-to-wake state. In fact, a number of components on the Mac shut off completely in the sleep state and there's no difference at all. Further, in neither case is the wear of likely to matter to the overall service life of the system (which will likely be obsolescent and have the mechanical and display components wear out first).
Incidentally, on PCs with very large or noisy power-supplies, your friend's advice is quite good.
If you live in an area that has frequent power problems (surges or brown outs) from the power company and you don't use a UPS with automatic voltage regulation, it's almost always true that turning off you computer completely is the better option. Power surges and brown-outs are far more destructive to machines that are powered on than those powered off.

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...

IMac Brightness forgets setting after shut down

Hi, I have an old iMac (not sure what year but it's the white model 24").
Everytime I log in, the brightness setting is always at the lowest setting. At the minute I'm having to change it everytime I go on my mac.
The iMac is running OS X 10.5.8 if that helps at all?
Please help, I've searched for the issue have found nothing so far

Someone had posted this link on another thread:
http://discussions.apple.com/forum.jspa?forumID=881&start=135
So I'm going to try that when I get home. Having Googled and searched these forums it seems I'm not the only one with fan problems, although there seem to be lots of varying issues. I'm now aware that shutting down my computer every night is not necessarily a good thing, but some threads I've read say that the diagnostics that Macs perform in the wee small hours don't get done if the computer is sleeping, either. So what is best? Just leave it turned on? I worry about leaving non-essential electric appliances on all night.
Any help would still be appreciated! Thanks.

IMAC G5 Starts up and shuts down.

My IMAC this evening started up, was on for 3 minutes and shut down. I then tried to restart 3 times but the power shut down... The third time the computer started up and is fine and running. Any idea what that is about? Thanks.

Hi,
Not sure what is going on but probably a good time to the check the hard disk just in case.
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) 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
Check for sufficient disk space also. Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see
Capacity and Available. Make sure you always have a minimum of 10% to 15% free disk space at all times.
Check your power cord to make sure it has a good connection. See here.

When iMac sleeps... it shuts down external hard drives

When I wake my iMac I get the error message that my hard drives were removed, could cause damage, etc. This just started today. It's almost like the iMac kind of goes into a deeeeeeeep sleep... but the computer doesnt shut down totally. I can still wake it, takes a little longer than usual though.
Anyone know what the issue can be?
Thanks

Do you have an external drive attached?
The reason for asking is I have seen similar errors when I fail
to properly unmount or removes an external drive.
There may be a better way but when I want to turn off my
external drive (used for TM and SD), I right click on he
external HD's icon and select the EJECT option. This unmount
the drive so the power can be turned OFF and removed
from the back of the iMac. You can also do with the Disk
Utility.
Try unmounting your external drives and restart to see
if this helps.

How to find out why my MBP will always try to shut down after 1 hour

Dear all,
this is a question too complicated for me to answer; I have previously tried to solve this problem in a usenet forum (comp.sys.mac.system) - but we didn't get it solved there, and I finally gave up on it. However, it still persists, and it is so annoying that I want to try another approach on it this time using the Apple Discussions Forum.
The problem is as follows: my relatively new (bought in december '09) MacBook Pro 13" (2.53 GHz Intel Core 2 Duo, 4 GB RAM) has a problem: always when I leave it untouched for one hour, something within the system would try to make the computer shut down (system halt). Please note right that this seems NOT to be a hardware-related issue (al least not simply a bad mother-board or sth. similar - there are a lot of threads about MacBooks that seem to shut down immediately, like fainting - this is not the case here). Instead, the system behaves like anytime when a user-requested shut down is invoked - for example, the running applications would check if any changes should be saved, and ask questions. The only thing is: I did not request a system shut down, and even more: I do not WANT the system to shut down. In fact, this whole problem is extremely annoying, since it constantly messes up my open documents (e.g. the TextMate workspace I usually set up, or similar things), forcing me to reestablish my workspace at least once a day. Over time, this can be very annoying for a computer that's used for work!!
During the course of my earlier discussions in the forum, we tried to find out what makes the computer go down - looking through the system log files etc. - but to no avail: we couldn't trace back the event that has caused the system to invoke the shut down procedure. However, it seems that this issue is related to the Mac operating system, and not the hardware - and this is why I ask this question here (and not in the MacBook Pro section). It may be that we simply didn't look in the right place - or not with the right tools - and I hope that there may be some people here with some new ideas how to trace the reason for this procedure. Everything I can tell now with some certainty (and I couldn't do it before in the usenet forum) is that the shutdown seems to be invoked about one hour after the system has been left untouched by a user (no key strokes, no mouse movements); I know this because I use my Mac for a wake up call now - and, since I sometimes need more than an hour for that, I can tell that this problem causes iTunes to quit one hour after the Mac has booted (which makes my wake-up music to switch off... and some of the running applications with no changes to save).
It would be very important for me to solve and remove this annoying problem, and I think that this really shouldn't happen! Needless to say, I haven't set the energy savings settings such that the system would shut down after one hour (in fact, I have set the system to always stay on when attached to a power supply); still, the problem prevails.
Does anyone of You specialists have a good clue or smart suggestion where (or probably how) else to look to find out what causes the shutdown? Thanks a lot for taking the time and considering this annoying problem!
Best,
Björn

Yes - it is a bit frightening... Had other Macs before this MacBook (Pro), and never experienced such a problem. Don't know - of course I look into the Preference settings from time to time, and maybe I have changed that setting on the other computers... it never occurred to me...
What an annoyance such a simple decision to make the auto-shutdown after one hour a default can be! Probably, Apple reconsiders :-D I'd rather prefer an auto-lock of the account (instead of an auto-log off)... but I believe it has been expressed often enough that, in this particular case, the - pardon me - Windows-solution (to offer a simple lock of the account, the Windows-L-key combination, IIRC) is much more practical... to copy that behaviour under Mac OS X, You'd have to go through lengths...
Anyway! Pondind, thank You very much!!! Solved a kind of embarassing, but huge problem of mine!
Best,
Björn

My mail program takes a long time to open and the whole system takes almost 2 minutes to shut down at night What should I do?

Hi, Recently my system has been slow to boot up in the morning & slower still to shut down at night.
Also my mail program is slow to open. I do have emails archived but my trash is always deleted & I'm trying to keep my "sent" folder not too full
Occasionally any programs I'm working in (Photoshop, InDesign, Illustrator, etc) takes time to process whatever task I'm doing. (This happens maybe once or twice a week, not often)
thanks
