My iMac never shuts down properly

My iMac never shuts down properly, sometimes it says that i need to force quit my wireless internet but even when i do that it just has the white screen and I have to hold the power button down to turn it off properly, why is this and how can i stop it

Hello,
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed. Or an errant process eating up RAM.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Satellite P200-144 never shut down properly using Vista Ultimate

Recently did a rebuild of my P200-144. Used recover disk with Vists Home. Then upgraded to Vista Ultimate. After that was complete went to toshiba web site for latest drivers and decided to update bios.
When the laptop was restarted it never shut down properly. Left with no choice but switched it off (left in logging off screen).
Now laptop will do nothing. Is there any way to get the bios to boot / restore itself or do I need to bring this to a support centre.

Hmm looks a little bit like the BIOS update has failed ?:|
Usually in such situation the ASP help is needed.
But before you will contact the ASP and will sent this unit to for the check I would recommend removing the battery and disconnecting the AC adaptor from the notebook.
Then wait about ~20min, then connect both parts again and try to start the notebook.
If you will be not successful then the help from ASP is necessary
Good luck

Why does my intel iMac not shut down properly?

On Shutdown, the screen goes black, appears to be shut down, but start button will not start unless you hold it in for several seconds. After machine boots messages says not shut down properly. Does this everytime. Has done it since it was new a year ago. the screen is black, but the button will not start the machine unless you hold it down, then you get the message. Have never seen anything like this. It is as if the machine thinks it is still running.

I'm not sure that a normal shutdown followed by turning off a power strip will reset the SMC. Power strips just switch off the "hot" leg of the power but do not interrupt the "cold" (neutral) leg or the "earth" (ground) connections. It may be that the SMC senses the cold-to-ground path or something like that to do a reset.
It may also be that the Mac hasn't actually shut down completely when you switch off the strip. You might try waiting a minute or two before doing that to see if it makes a difference, or listening carefully for any noises coming from the Mac after the menu shutdown before hitting the power strip switch.
I sometimes use an old veterinary stethoscope to listen for sounds coming from Macs for troubleshooting purposes (although never yet with a MacPro) & have noticed that the screen goes dark a little before everything else is fully shut down.

My iMac (2011) wont shut down properly!!

I have contacted apple's phone support 3 times but it still won't shut down properly.
1. they asked me to do a pram reset
2. they asked me to go into the safe boot mode (and it does shut down properly)
3. they asked me to clear my cache (it shuts down after i cleared it but i have to force shut my computer and wait until i swicth it on again to empty the bin and then it shuts down properly)
4. they asked me to reinstall my OS(but thats such a hassle and there shldnt be a problem with the OS bcos it shuts down normally on safe boot)
Are there any other solutions to this? It's been happening for the past 3 months... I suspect that it's the third party applications that are causing these problems. I tried reinstalling them but it still won't shut down. (eg, photoshop, filezila, firefox)
HELLP!!

If you're able to boot, 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.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Select the most recent panic log under System Diagnostic Reports. Post the contents — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post "shutdownStall" or "hang" reports.
If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is slower than normal, and some things won’t work at all.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.

Since installing OSX 10 my iMac randomly shuts down and restarts. I can not determine why this is happening. Any ideas?

Since installing OSX 10, my iMac randomly shuts down and restarts. I can not determine why this is happening. Any ideas?

1. This is a comment on what you should and should not do to protect yourself from malicious software ("malware") that circulates on the Internet. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandboxing security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you always stay within a safe harbor of computing practices. How do you know what is safe?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is unsafe.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are outside the safe harbor, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe. For instance, if a web page warns you that Flash is out of date, do not follow an offered link to an update. Go to the Adobe website to download it, if you need it at all.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
"FREE WI-FI !!!" networks in public places are unsafe unless you can verify that the network is not a trap (which you probably can't.) Even then, do not download any software or transmit any private information while connected to such a network, regardless of where it seems to come from or go to.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. Most of the real danger comes from highly targeted "zero-day" attacks that are not yet recognized.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular trojan it is, but do you care? In practice, there's seldom a reason to use the software unless an institutional policy requires it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither should you assume that you will always be safe from exploitation, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

My 21" iMac unexpectedly shuts down

I have a 6 month old 21" iMac i5. Around two months ago it started shutting down completely as I was using it. If it turn it on inmediatelly o in a short period of time, its more likely to shut down again also in a short period of time. But if I disconnect it for a while and then turn it back on, it will work for a longer period of time, but later on it will eventually shut down. I've taken it to the authorized shop where i bought it from (I live in Ecuador) and twice they ran a 3 day test but they didn't get any results and told me the computer never shut down. Brought it back to my office and the problem persists. I've read other people are having the same issue but I haven't seen they have solved the problem. I am really concerned about this because the people at the authoriced store told me that apple won't make the warranty work as long as the tests don't show any problems. This iMac is my main working tool and every time I've taken it to have those tests run I lose a lot of time and work.
Hopefully someone will have the solution to this problem.

My iMac wont' shut down..

I already upgraded my OS to 10.5.7, and I have a trouble because the computer don`t shut down properly, When I ask to shut down, It seems as if it where to run the shut down routine, but at the last moment when the cursor icon disapear, the wallpaper don't go out, and stand there, and remains there, and still shows the wall paper, and finally I have to push the shot down button to finish my work, I'm the only user, I'm the Admin.
I try login out and using the shut dow command from the accounts window, and the problem remains.
When I install the new OS I erreased and install, so everything is new, I have a Maxtor One touch 4 (500 gb) USB.2 external drive connected to the computer and I use it as back up and second drive ( It's partitioned ). I had noted that the drive can't be unmounted in time when the shut down command is running and I believe that this block the operation because when I expulse the drive, the shut down routine seems to run well, this is a problem when the time machine runs the the midnigth back up, because the computer remains on until the next morning, my question is.
¿This is normal? ¿What can I do to shut down my computer without expulse my external drive first?
¿ there's a script to force the external drive to be unmounted while the shut down is running?
I read about the firmware updates before install the new OS, but I couldn't found nothing to update for my old and beloved Imac, ¿ There's something that I have to update?
Please if there's something that I have to know, please tell me...
For the moment I will continuing shutting down my computer as I describe above...

Hi Rachael,
Try resetting the SMC (System Management Controller) and see if that does anything.
Here is how to do it: http://support.apple.com/kb/HT3964

IMac wont shut-down

Hi folks,
i`ve got an Intel iMac 24 inch 2.16 GHz Intel Core 2 Duo with Mac OS X 10.4.11 installed. Very often the iMac wont shut-down. When i choose the shut-down command from the Apple menu the Finder quits, the Icons on the desktop, the Dock and the Menu bar disappear. Then the screen turns blue and i see the grey spinning wheel but it wont go further. I always have to disconnect the power cord to shut-down my iMac. Here is what the system.log says:

Perhaps this is an app booting on launch that's not helping matters. Here are some ways of preventing items from opening automatically ...
If the login window appears when you start up your computer, hold down the Shift key and click the Login button. Continue to hold down the Shift key until you see the Dock.
If you don’t see the login window when you start up your computer, hold down the Shift key when you see the progress bar in the startup window. Continue holding down the key until your desktop appears and the startup completely finishes.
Choose Apple menu > System Preferences, and then click Accounts. Select an administrator’s account, and the click Login Items. If any unwanted items appear in the list of items that open automatically, select the item and click the Delete - button.
You could try resetting the SMC. http://support.apple.com/kb/HT1543

HP DV6 3209 TX does not shut down properly & sometimes very slow

Hi,
I bought a HP Pavilion dv6 3209 tx laptop only one month ago. It provided Win Home Basic. I tried to install Ubuntu 10.10 Maverick along with it, from a pendrive .... I didn't get installed, & at that time, The screen suddenly became colourful with some bizarre symbols !! I shut it down with the power key.
Since then, The home basic became very slow, cpu usage often reaches 100% or very high even while idle, does not shut-down properly.
Then I formatted the hard disk,clean-installed Win 7 Pro (Got it from msdnaa) as well as ubuntu maverick. Now when I restart the system, it shuts down & restarts. But if shut down, then the desktop goes blank, but the fan keeps running, power indicator keeps glowing, system never shuts down till the power key is long-pressed. Also, The CPU usage becomes very high, sometimes it's normal.
I'm confused. Is that any hardware issue ? Do I need to format it again, install xp sp3 & check it if the problems remain ? Please help !!
when the lappy runs in Ubuntu, it's operating speed or CPU usage is normal ..... even when I'm writing this reply from Win 7, everything is normal, but sometimes it's not so smooth...... task manager shows CPU usage as 90 % or more !! I've decided to install xp & then check if the shutdown issue & slowness remains there too.
Windows-Linux-Unix-Mac

SOLUTION :
Open the BIOS (at the starting press f10).
f9 to restor default
Then save and exit (press f10 again)
Restart the computer.
Do this again and set it back to "Enable" that wil help the computer to not over heat.
And now your ROVE will start and sleep correctly.

Can i create mcx for shut down properly mac when battery is less 5 %

Hi hello
Can i create mcx for shut down properly mac when battery is less 5 % ?
Thanks for your reply

You can create a mailing list by using the "Groups" feature of Address Book. Simply select "New Group" from the File menu. Name the group, and drag the contacts you need into the group.
In Mail, open up Preferences (under the Mail menu), and click on "Composing". Then make sure that "When sending to a group, show all member addresses" is unchecked.
The auto reply is a feature that is better done on your mail server, as you Mac can only send an auto reply when it is on, with the Mail application open. If you use dot Mac, you can set up a vacation responder through the web, and you can leave your computer switched off.
If you really want to leave your Mac on when you are on holiday, you can set up a mail rule (Preferences, Rules).

How to track down an app that is preventing my iMac from shutting down

Hello! I lately discovered that an application is preventing my iMac from shutting down . I have The Sims 3 installed on my computer but i don't think it's preventing my computer from shutting down.
So my question is, how can I find out what app is preventing my iMac from shutting down.

What's Keeping Me?

Another iMac Randomly Shutting Down!!

Hey Everyone. I'm new to the forums, though i've always used them as a resource over the years to learn more or troubleshoot issues. Hopefully, now, someone can help me with mine personally.. :-/
I have an intel 2.8gH Aluminum iMac that I purchased fall of 2007. Only now, almost 2 years later is it suddenly (just started yesterday) turning off randomly. Everytime it will not allow me to turn it back on until a minute or so has passed. I have reset the SMC as well as the PRAM several times. This afternoon, it is now to the point where I cannot even keep it running long enough to download an app to up the fan speeds. Although, I don't think it is overheating in the first place.
I'm really hoping it is just the power supply, as I've seen that be the fix for SOME iMacs i've found at other online forums. Though, the upper corner of my iMac is not hot or smelling burnt out at all. I have found more than several online forums of people complaining about their iMacs randomly shutting down, and am praying it is not the logic board, as that is a $900+ fix.
please, someone give me insight to how i can check if its the power supply or something else? I use this iMac for recording all of my music, editing video, and (of course) playing WoW lol. Currently using my 1st gen macbook.

I bought my iMac 20" in May 2006. I had been very impressed with it until one day I shut it down to move it to another room. I could not get it to turn back on. I had to leave it unplugged for a few hours. Since then it has started randomly shutting itself down, turning itself off and not starting up again until I unplug and leave it unplugged for a few hours. I had purchased the Apple Care? Extended Warranty, and the fault occurred during this three year period, though I failed to take the fault seriously and did not phone during the period. It was just after the three year warranty that I phoned Apple Care? about it and everyone I spoke to said they had not heard of this problem occurring. I wonder now, why the Apple Customer Service Team don't visit the discussions.apple.com where they will find quite a significant number of like problems occurring with the iMac sold in 2006.
My reason for paying the nearly triple price point for an Apple Computer was the quality of the build and my expectation that I would get far longer life out of my purchase. I don't like buying throw away products and I gladly save and wait longer to buy better quality products. Just as an example and point of reference. In 2000 I purchased a second hand Dell with 8GB HDD and 256Mb RAM. I paid $1000 for it and I gave it to my father when I got this iMac and he still has it running today. It has not had a single hardware issue in nine years. Good luck I suppose. However, after spending around $3000 on this iMac, and Apple now telling me the Logic Board is generically, non specifically 'failing', it goes against my pure desire for non disposable, throw away products to buy another Logic Board for AUS $1064. For one, I don't believe it has given me anywhere near the life that I expected from a product with such a high price point and solid reputation for quality, nor do I feel confidence in buying anything more 'Apple' after the dealings I have had with them over this problem. I am amazed that Apple would sell a 'failing' Computer to their customers and then expect that the customer will spend more money, considerably more, on a product that may be equally faulty and that they will not stand behind either.

Wont shut down properly

MacBook new reinstall of 10.7.5, will not totally shutdown. I have to use the power button to shut down totally, then on startup it tells me it has not been shut down properly. Restart is the same thing. Tried disk permissions, repaired them, but still a problem ... help!!!

Well I just got home so it has not been spinning for about three hours.
I have tried to force quit it to no avail.
I think I will have to make an appointment with Apple to see just what is going on since I don't know anything else to try. I guess when I wake up in the morning the battery will be all used up.
I thought that maybe if I connected to my computer it might kick it into a working mode but that did not happen. i only got an error message (OxE8000065). whatever that means.
Any other ideas?
Thanks for all of your help.

Is it okay if we never shut down and just make the computer to sleep or we just put the flap(screen) to save the energy?

I recommend users to put their computers into sleep mode to save energy, and also, they won't waste time turning on their computers. You should only turn off your computer if you aren't going to use it for a very long time, but sleep mode is perfect. If you just turn off the display, your computer will still be working, so you mustn't do this unless you are going to use your computer in a short time
