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 out

Hi,
My new macbook pro cannot shut down restart or log out. When click shut down restart or log out. it does NOTHING. no screen comes out, no window telling me that an application is stopping the shut down, just nothing. After I try several times to shut down, I can continue using my macbook normally as if I didnt try to shut down at all. What should I do? What is wrong?

What happens when you press the power button? It should bring up a dialog box asking if you want to Restart, Sleep, Cancel, or Shutdown.
Also, try it from the terminal prompt. The Terminal application is in the Utilities folder. The Utilities folder is in the Applications folder.
Once you've launched Terminal, type:
sudo shutdown -r now
Enter your login password when prompted.
This should initiate a reboot.

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).

Won't shut down, restart or log out

Running 10.4.10 on G4. Will shut down apps but does not do anything further. Also, screen saver hot corners don't work. Don't know if that is connected to the shut down, etc. problem.
Looked at HD, lib, startupitems folder but it is empty. Eliminated startup items thru sys prefs but no help there either.
Recently installed ITunes 7.3.2 and security update.
Maybe time for an iMac ??

Since downloading Lion on my Mac Pro I can not shut down, restart, or log out on my computer;

I tried both the Apple menu and the keyboard shortcuts and nothing happens when i do both of them. I can not do a software update now because of this

Bat signal? What's that?
Mike, try resetting the Power Management Unit (PMU). Read the linked article, then scroll down to find the instructions for resetting the PMU on your model, then do this:
1. If the computer is on, turn it off.
2. Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
3. Wait 5 seconds.
4. Press the Power button to restart the computer.

Since I installed Mountain Lion, my iMac has shut down after 15-20 minutes. I have adjusted screen saver, shut down time, and sleep after. Nothing seems to help, any ideas?

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

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.

Mountain Lion won't sleep

Since I installed Mountain Lion my computer will not sleep. This appears to be a different problem from what others are experiencing. Unlike what has been referred to on other threads, all items in my Apple menu (except Sleep) are functioning normally. However, none of the normal methods (keyboard shortcut, Apple menu, power button, Energy Saver) will put my computer to sleep. When I try to sleep the machine the only thing that happens is the cursor freezes on the screen, as though the only thing that has gone to sleep are the input devices. Tapping the spacebar unfreezes the cursor and the machine functions normally.
I have closed apps, removed peripherals, started in Safe Mode, reset PRAM, and nothing changes. Turning the computer off to save power is not a realistic option in my workflow so, for now, I'm just burning the kilowatts whether I need them or not. Any help would be appreciated.
8-core MacPro3,1

I'm on a MacPro and sleep did work when I installed ML but then out of the blue just quit.
The screen would go black but the system would not go to sleep (white LED stayed on full, touch a key and the screen lit right up, wasn't sleeping). I tried everything, cleaned out all my preferences, went through all system preferences a dozen times, deleted a couple of apps that I had recently installed.. on and on and on, for days. I even reinstalled the update (that was already installed) OSX 10.8.2 overtop of itself hoping that would work out the kink.. Nada !
I could boot up from a separate bootable hard drive on my MacPro (holds 4) and it would go right to sleep, using every different command there was to put it to sleep but as soon as I switched back to my main system hard drive.. Nada ! I was just ready to run the terminal check (stated above) but was holding off cause I am not totally up on using it, have in the past but only once a couple years ago.
I even tried setting up a new user account and that wouldn't work either. Then I saw one of the above posts that said they had print sharing turned on and that solved their problem. I checked but I didn't have any settings of any kind turned on for sharing and I'm the only user of the machine.
THEN (don't ask me why), I remembered that a couple of days ago I got a warning from my Epson Wireless NX430 printer that I was low on black ink. It still printed fine so I didn't change the cartridge, wanting to drain every last drop out of it because they cost so much. So I sat there and said to myself.. I wonder.. No, it couldn't be. So I went to my Epson printer and everything looked fine, it was in the sleep mode as it usually is when not being used.
I hit the power up button and lifted the cover to change the cartridges (decided to change the black and cyan since I was doing it as both showed low). I changed the two cartrideges, closed the cover, the printer ran through its "charging cartridge" function. I came back over to my MacPro and hit the Opt + Command + Eject key and my MacPro went right to sleep, didn't hesitate for one second, went to sleep mode and the white LED on the front of my MacPro went into pulse mode (instantly) showing it had shut down and was sleeping comfortably..
UN-FRICKIN BELIVEABLE !!!!! Days wasted, programs trashed, clumps of hair on the floor ALL FOR NOTHING !!!! Hope this helps somebody else so you don't have to go through this mess !!!!!!!!!

FW800 won't sleep -- shuts down instead...

So there are many here who are having sleep/power control related problems, however I'm having a slightly different problem. As the subject line states, my FW800 Dual G4 won't sleep. Rather, when I select sleep it simply shuts down.
I have replaced the battery, reset the PRAM, reset the PMU, and reset the NVRAM, without success.
I suspect, however, maybe it's related to software as I can load up new system software and everything works fine. By the time I update everything to the latest software, including iLife, it no longer sleeps.
Short of taking the machine in, does anyone have any further ideas?

I have this;
If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
Restart your Mac and immediately hold down the Command-Option-O-F key combo until you see a somewhat intimidating command-line display that ends with the Open Fimware prompt. Type the following line:
reset-nvram
press the return key on your keyboard
set-defaults
press return
reset-all
press return
Your Mac will reboot. Once it's running, put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.
Still didn't work? Might be time to call AppleCare or see an Apple Genius or a technician
Cheers! DALE

My macbook pro won't shut down, restart or log off

it's a month old. was behaving fine until about a week ago when it wouldn't shut down because itunes kept restarting itself whenever i quit. realised it was because of my alarm clock widget, which i've now removed. so the itunes is sorted, BUT, my mac still won't shut down.
what can i do? someone told me to download onyx but i haven't a clue what to do with it?

Don't upgrade to Snow Leopard in the hope that it will eliminate any preexisting problems on your MBP — it almost certainly won't, and you may have other problems as well (e.g., incompatible applications and startup items). Solve the problem first, then perform the upgrade.
If you Safe Boot the computer, will it shut down normally afterward? If so, disable all third-party startup items (System Preferences > Accounts > select your account and click the Startup Items tab), boot normally, and test again. If you can still shut down normally, one of the startup items is at fault. Re-enable them one at a time, testing after each addition, until you determine which one is causing the problem.
There are also applications that can run in the background and don't show up in the Force Quit dialog box — but they do appear in Activity Monitor when you instruct it to list Active Processes. Some can interfere with shutdown by refusing to quit when the Shut Down command is given. If the suggestion in the preceding paragraph yields no progress, let us know what processes are active on your computer when no applications are shown in the Force Quit dialog box.

Finder View options, won't stay set after restart or log out

I like to have my application and utility folders (in the finder side bar) open in icon view and arranged by name and my Home and Movies folder open in list view with files arranged by name.
Each time i log out of my computor or restart the view options i have mentioned are reset, which is extreamly frustrating.
I have also noticed that the finder window now opens in a small size in the middle of the screen rather than being aligned to the left hand side as like to have it set.
This problem has only occoured recently, i think after deleting some "relic" files using Cleanapp.
Any ideas on how i can sort this out greatly appreciated

I finally know what causes folders to lose their view settings - even if you have set them to "Always open in..." a particular view (but I do not know how to fix it).
The trigger is setting any window to "column" view. Try it.
(1) Create a new folder, and set it to your preferred view (but not column view). Close the folder and re-open it to verify that it is in the view you have set. You can even set it to "Always open in..." that view, if you like (it doesn't matter).
(2) Now open up any other finder window or folder, and switch it to column view. If it is already in column view, switch it to some other view and then back to column view.
(3) Now go back to the folder you created in step 1 and open it. Presto: column view. (Aargh!)
I confirmed this with a helpful and sympathetic Apple support staffer at the Genius Bar in my local Apple Store. Unfortunately, he had no solution, but noted it as an apparent bug in the 10.7 finder.
This is an extremely reliable behavior, that I have confirmed on 5 different machines all running 10.7.2. It is also an extremely frustrating behavior that I hope Apple fixes soon.
-Barry
P.S. I will copy this to similar threads where this is being discussed, in hopes that it is helpful. Sometimes understanding why something happens can make it a little less frustrating, even if you don't know how to fix it.

Safari won't load after installing Mountain Lion. If I shut down and unplug the internet connection for a minute, it starts working again. But only for awhile.

Help!

Hi,
Mac OS: Long Delay Before Web Pages Start to Load, Then Load Suddenly at Normal Speed
*I tried entering a manual DNS*
If you have not tried Open DNS, go here. Open DNS
Just click the computer icon and follow the instructions.
Empty the Cache. To empty the cache memory go to the Safari menu and click 'Empty Cache
Reset Safari go to the Safari menu and click 'Reset Safari.. select the first 5 buttons and click Reset.
To delete Safari's icon cache using the Finder, open your user folder, navigate to ~/Library/Safari/Icons and delete its contents.

Macbook Pro will not shut down/restart/sleep/log out after Mountain Lion update

Dear all,
I upgraded from Lion to Mountain Lion yesterday and since then I have encountered a few issues:
- The only way I can shut down my computer is to hold down the power button or entering commands in terminals. The commands under the Apple menu do not work at all. No window opens when I click on it.
- The about this mac, force to quit, sleep, shut down and restart button, log out do not work.
- When I restart my computer, it takes 3-4 minutes to log into the account (it used to be less than 1 minute, I have an SSD).
I have tried all of these solutions to solve the problem:
- I created another user account and I do not encounter the same problems. It logs in quickly, can shut down etc.
- I have repaired the disk and the disk authorisations using disk utility
- I have cleaned up all caches and did maintenance using OnyX
- I have cleaned up all ACL using terminal
- I have never installed Kapersky (this was the cause of the problem for some people in the past)
I am starting to be a bit short on ideas. All I know is that there is a problem with my user account. I do not want to do a clean install as I have quite a lot of work stored on this user account and preferences that took me ages to set up. If I have to start fresh I will but I would rather avoid this extreme solution.
Has anyone else experienced such an issue? If yes, how did you solve it?
Thank you very much

Had the same problem and this worked for me:
Try deleting following two items:
~/Library/Preferences/com.apple.dock.plist
~/Library/Preferences/com.apple.dock.db
Make sure you take a screenshot of your current dock since deleting these files will reset your dock to default.
Now open terminal and do a sudo reboot w/ your password.
This solved the problem for me.

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:
