  • IMacs suddenly shuts down

    Hi,
    Since a while my iMac suddenly shuts down and reboots.
    It starts with a frame freeze, can't move the mouse cursor. After a few seconds my iMac shuts down.
    I have no idea what the problem can be.
    This is the report of Console when it shuts down.

    Hey MagicMarcus,
    Thanks for the question. I understand that you are experiencing issues with your iMac unexpectedly shutting down or restarting. The following resource provides some great information if this happens, along with potential resolution steps if it is a reoccurring issue:

  • Spontaneous shutting down.

    My Power iMAc G5 10.4.11 is spontaneously shutting down when I close all open apps.
    This has never happened before and energy saver shutdown does not appear active when checked.
    I know this is an old iMac and I will be replacing it later this year, but it works fine otherwise and does everything that I need it to.
    Any advice?
    Many thanks.

    Have you reset the SMU?

  • Mini spontaneous shut-down and application shut-down problem

    Help!
    I've searched. I've read. I can't find the answer!
    After I updated my firmware several weeks ago (to SMC 1.3f4), I've had problems with spontaneous shut-down of the computer, and a frustrating application shut-down issue (Safari, Mail, Word--you name it!).
    I tried to find the other firmward update from last summer, which I read about in several posts from July/August, but the link is dead (Mac Mini Firmware update 1.0.1).
    Coincidentally, after an office break-in two weeks ago, I FileVaulted my computer. I thought my problem must have to do with that, but all the posts I can find here are about this firmware thing.
    Should I/can I reinstall the SMC 1.3f4 update? Is there some secret to the no-longer-available 1.0.1 update?
    Can anyone help me? (I would certainly appreciate it!)

    Try a safe boot, hold the shift key and power up, this will take a little loner than normal, hold the shift till you see the progress bar. See if it works normal, if it does than it is more than likely some 3rd party software.Then restart normal and check your console for panics. That would be your isssue.  You can also start holding command R and restoring from utililities.  Back up before you do anything.

  • 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.

  • HT201178 Keyboard was paired with IMac the shut down, computer is locked and keyboard cannot be found.

    My Imac got shut down and is locked (password protected) I get a message showing keyboard not found. I now cannot access my computer.

    You need to use a wired keyboard to boot the iMac.

  • Trying to add our Epson 4800 after updating 10.8.3. our iMac is shutting down and so is our Mac Book Pro.

    Trying to add our Epson 4800 after update 10.8.3 our iMac is shutting down and so is our Mac Book Pro. Any advise??

    Thank you Linc. We just half solved our problem. The update 10.8.3 has a bug for using our printer with a special kodak proback firewire cable by don't giving a support. So we skipped the old way by downloading a new driver,
    using an USB cable and adding our printer again and it works. The reactions of collegues and those on the Apple site showed us that the update 10.8.3 is having a major problem.

  • AirPort Extreme powers down when iMac is shut down

    9-month old AirPort Extreme, with two hardwire connections: one to the DSL modem, and one to an iMac. After months of perfect performance and reliability, the AirPort extreme now completely powers down as soon as the iMac is shut down or goes to sleep. It powers back up with the iMac. Logging out the iMac to another user account does not shut down the AE.
    Naturally, we checked the electrical supply for all three devices and they are all plugged into a perfectly ordinary surge supressor strip.
    We're thinking the AE has a hardware failure...but what kind of bizarre symptom is this that it shuts down when it loses signal from it's only Ethernet client?

    This is certainly odd. Have you tried a different port on the AEX?
    It may be best to contact Apple about a warranty exchange.

  • IMac G5  shuts down unexpectedly

    Hi friends at Apple Discussions,
    This week my iMac has shut down by itself unexpectedly about once a day. Immediately after it shuts down it will not start up, although after a 10 minute wait or so, it will start up and run just fine. Nothing had been changed, hardware or software, recently that should have caused this.
    It is a Rev A machine. Serial number is QP507XXXX. Within the first 6 months of ownership, she had a power supply failure that was repaired under warranty by an Apple Retailer. Everything has been great since then.
    I understand that this might be another Rev A hardware failure issue and I believe I am still inside the three year repair window. However, I also understand that there are often preliminary steps to take before jumping to that conclusion.
    Any advice as to what action should be taken next? I appreciate your expertise.

    Status report...
    In previous posts I did not mention that I am not under AppleCare. The tech was willing to help but suggested that I might try isolating/replicating the problem on my own. Otherwise, if I take it in and they find it is a software issue, not the hardware issue, I get charged.
    His suggestion: Try an archive and install for a couple of days, see if problem still occurs. That will determine if it is a hardware or software problem. Actually, I believe I'll do a clean install instead for a couple of days, as my entire hard drive is cloned & bootable on my external LaCie drive. This is an inconvenience and steals my time, but its easy enough to do, I guess.
    So I'll do it, but the question lingering in the back of my mind is...is this actually necessary? Does software shut a machine down randomly and prevent it from booting up again for the duration of some unknown 'cooldown' period? Besides, the only software change I have made relativly recently was installing Camino I am highly skeptical that its a software issue. But because I am not an expert, I will follow the suggestions.
    Any comments on this?

  • Firefox 3.6.10 on WinXP spontaneously shuts down without warning after a certain time, whether or not the Internet is in active use, without disrupting or otherwise affecting any non-Internet programs running simultaneously.

  • IMac randomly shuts down after Leopard Upgrade

    My wife's iMac randomly shuts down since we installed Leopard. It wasn't doing this before the Leopard upgrade.
    It takes about 5 mins. of inactivity after the machine enters sleep mode, then it shuts down. We've searched the Discussions but have yet to see an answer to our question. Nothing but an iSight is plugged in to the machine. Any suggestions?

    Same problem with random shut downs that get more and more frequent making the computer unusable. Took to Apple Store where they did not recognise the problem - tried replacing RAM then power cable then power supply. Said problem was fixed but started to recur within a short time of using it back home. Used install discs to reinstall the original operating system (Mac OS X 10.5.2) and the problem resolved - on upgrading to Mac OS X 10.5.8 the problem immediately recurred. Have gone back to 10.5.2 now and all seems okay.
    Seems strange that there are so many postings about this and Apple Store (Genius staffseem to be unaware of it as a problem).

  • IMac 27 shuts down at intro

    hello my iMac 27 shuts down at intro or when i trying to set it up ,i  think its Fan or HDD but not sure , maybe anyone knows where is a problem ?

    Is it an earlier iMac that came with say a 10.6 Install Disc?
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

  • IMac randomly shuts down

    My IMac randomly shuts down. I have the energy saver set for computer to sleep after 1 hour. I have not installed any new software. This problem began about a month ago. I have to use the restart button and always get an error, that the computer shut down unexpectedly. I copied one of the Panic Reports if that will help resolve the problem. I have checked the "maximum temperature" in Console and get no messages and many messagfor "shutdown".
