Why is my iMac automatically shutting down?

Recently the Mac has begun to shut down without prompting. Energy saver is set but the shutdowns do not seem to be a result of that. Any ideas on what's happening here? Thanks in advance.

This has been going on for a couple of weeks. I checked my settings for energy saver, but started here for troubleshooting. Another thing I noticed is when the machine is cut back on, the volume is all the way down and the finder window displays. Even if I had the volume all the way up, it reverts to silence when restarted. And the Finder window appearing is another mystery as I don't keep that window open.
To the other point of over heating, I guess that could be a cause, but I have seen no evidence of overheating and run iStat Pro to check on temps, etc.

Why does my iMac not shut down when I try to shut it down?

Wh does my iMac not shut down, or restart when I try to do either. It just sits there with the little loading circle continuously moving. The only way I can shut it down is if I hold down the power button to shut it down. Can anyone tell me why this is?
Thanks!

Open your Activity Monitor and check to see what is running?
If there is some important Process running, then it is better to wait until it has finished instead of cutting the power and corrupting who knows what?
If there is nothing important running, then follow the instructions in the link below for resetting the SMC.

Why will my Imac not shut down unless I force it off

I have 10.58 version and lately it is not shut down unless I force it by holding power off. How can I correct this.? Also, I get a continuous spin when I select share folder in my system preference so I can select share internet. I have Verizon mobile broadband.

We'd need to see them posted here to see if it was a problem, but if it isn't repeating in Console now as it's open, hen likely not a problem.
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 Shut Down 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
What happens?

Why does my iMAC 2011 shutting down intermittently?

It will only restart after I turn the power source off & then on.

It's most likely bad or loose RAM, but could also be a more serious hardware problem requiring service.

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.

Dreaded Black Screen and automatic shut-down. Why does this happen ?

Why do I get a Black Screen and automatic shut-down ? My iMac felt warm...and I never hear a fan go on..could overheating be why it shuts down?

Hi Tish,
A few things.
If you bough this iMac used with no original install/hardware test discs, you can call Apple at 1-800-MYAPPLE ask for software sales and tell them you need a set of iMac replacement install/hardware test discs. You'll need to give the Apple rep your iMac's serial number.to get the appropriate discs. There will be around a $16 or $17 U.S. charge for discs.
Since your iMac is still freezing, I now wonder if it is RAM and/or hard drive related.
Your iMac maybe freezing because of serious lack of RAM.
How full is your Mac's hard drive?
You only have 1 GB of RAM installed.
OS X 10.6 Snow Leopard really needs more RAM than this.
Intel versions of OS X use more CPU, GPU, RAM and hard drive resources.
OS X, running alone (without any other applications running) can use up between 2 and 4 GBs of RAM memory.
Youf iMac model can 4 GBs of RAM, but only about 3.1 to 3.3 GBs of it will be recognized.
Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).
Without being able to run the Apple hardware test we have no way of knowing the condition of your iMac's hard drive.
The freezing could, also, be caused from a failing hard drive.
If you do not have any backup of your data, this is the time to create one.
Backup your important data to either DVD discs, flash drive/s or purchase an external hard drive to backup all,of your data to.
You can make an exact clone of the data, on your internal hard drive, using a data cloning like CarbonCopyCloner or SuperDuper. OR purchase the external drive and use OS X Time Machine to automatically backup your entire internal drive.

Why does my 2009 27" imac keep shutting down?

why does my 2009 27" imac keep shutting down?

Could, also, be failing hard drive , power supply or logic board.
You may have to make an appointment and take your iMac in to Apple or Apple authorized repair center for diagnostics and a repair estimate.
If your iMac has a 1 TB internal hard drive, it maybe a Seagate drive and maybe eligible for free replacement under the Apple Seagate 1 TB internal hard drive replacement program.
If you can get your iMac running, you need to backup all of your data ASAP!. Either backup to optical disc, flash drive/s or purchase an external hard drive for backup. You can use a data cloning program such as CarbonCopyCloner or SuperDuper to make an exact copy of your iMac's internal hard drive.
You can check for eligibility for free hard drive replacement by inputting your iMac's serial number here.

I have a late 2008 iMac with dual intels and the fans won't come on anymore. About every 1 1/2 hours, it automatically shuts down to cool off. Is there any way to manually turn it on? Or, do they have to be replaced?

About every 1 1/2 hours, it automatically shuts down to cool off. Is there any way to manually turn it on? Or, do they have to be replaced?

I tried that with no improvement. I think I might have to have the fans replaced. do you know if this is a particularly difficult procedure? Something wierd that I've noticed is that if I have a video on for more than several minutes, the fans comes on, and also when I am on a Skype video conference for awhile. Otherwise, the fan jst doen't come on as the intels heaten up to the point the the auto shut down kicks in...any advise? This definitely interupts my work! Thanks for your help and input thus far!

IMac randomly shuts down. Any ideas why?

Brightness control drops to minimum whenever my Imac is shut down

I recently upgraded to Leopard. Since then every time my IMac powers down, but not in sleep mode, the screen brightness drops to the minimum level. Why does the IMac doe this and how can I maintain the screen brightness that I set through system preferences, displays whenever I have to do a shutdown? Any suggestions out there?

Me too! I recently switched from keeping my iMac on all day but in the sleep mode to automatically shutting down every evening and waking up every morning. After making these changes in the energy saver control panel my screen brightness also drops to the minimum every morning.

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.

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...

Powerbook 17" G4 automatically shuts down in sleep mode

Powerbook 17" G4 automatically shuts down in sleep mode intermittently. When press power button to bring it back up, it takes a very long time to reboot and the date is set to Dec 31, 1969. It comes back up finally, but this is irritating.
Thanks for any help,

Hi Reaskt
Have you tried using Temperture Monitor to monitor your temps? Maybe it is overheating. Also it sounds like your backup battery is dead, that's why the clock reset's it's self. If you still have applecare I would give apple a call a soon I could. To me it looks like you would need a new logic board. I realy hope that you have applecare. Also have you tried an Erase and Install? Have you tried running Disk Utility booted from your install CD?
Post back when you get more info

IMac is shutting down when it attempts to sleep with 'hibernate image' error

Our iMac is shutting down when it attempts to sleep. This started following a Yosemite security update, though of course it is difficult to determine for sure that that was the cause.
In the console, the following message occurs before every shut down:
kernel[0]: Failed to get hibernate image filename
Suggestions? Does someone perhaps know what exactly the hibernate image is (we have a tiled screensaver that shows an iPhoto album -- could it be that one of those files is corrupt?) so that I can attempt to change it to see if that fixes the problem?
Thanks!

Already tried:
I reset the SMC by following Apple's instructions for this computer (turn off, unplug, wait, replug, wait, turn on)

More information:
1. It looks like the crash/shut down is happening when the display tries to sleep (timing is 15 min after the beginning of automatic sleep).
2. When sleep is first initiated, I am seeing this in the console (not normal?):

Automatic shut downs

Hello my mac keeps shutting down on its own. I keep it on, but close it. After a while when I open it up it automatically shuts down. When it starts back up it says there was an error which caused it to shut down. I haven't downloaded anything suspicious. Why is this happening?
