IMac randomly shuts down. Any ideas why?

2011 iMac just shuts down by itself. Ran the maintenance scripts, rest the SMC and have tried resetting PRAM. Anyone else have the same problem or better yet a solution?

  • Safari and Word keep shutting down, any idea why?

    I have a Macbook since a little more than 3 years, but recently Safari and Word keep shutting down. Is there any way to fix this or my laptop is going to die?

    Are you sure its those two programs or is it a mac fault, if not you could try reinstalling the software

    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.

  • 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".

    Hi Raydream ,
    Try another outlet in another part of the house
    Do you use a surge protector? do you have another surge protector to try? Just in case some thing is wrong with the surge protector your using. Also dose any thing else turn off or just the computer.
    things you can try:
    Make sure your software is up to date:

  • 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.

  • 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 Randomly Shuts Down -Overheating Problem?

    I've posted in these forums once before about my iMac randomly shutting down. I believed I had solved the problem by following another users instructions which were as follows:
    "Machines that are just randomly shutting down are usually caused by defective hardware. The only thing that can be done about that is to call Apple and have it replaced or serviced. There is probably not any one particular solution as it could be any number of the internal components failing and the resulting symptoms could be the same.
    If you'd like to do some hardware tests yourself before calling Apple that can be done. First try resetting the SMC: http://docs.info.apple.com/article.html?artnum=303446
    Next insert the original gray install disk, restart your iMac, then hold down the "d" key until it boots up into the Apple Hardware Test. Run the extended test.
    Also if you have Apple Care install TechTool Deluxe from the cd provided. Then run TechTool on your system."
    I also removed and replaced of a defective external HD that I thought my be causing problems. But after all these steps, the machine kept turning itself off.
    I had read in some forums that it was due to the internal temperature of the iMac. So I downloaded smcfancontrol 2.1 and increased the fan speed on the internal fans. This did bring down the temperature as revealed by the iStat Pro widget. However, I still had another shutdown.
    So I turned off the machine, went to bed, and this morning when I turned it on iStat Pro said these were the internal temperatures of the iMac:
    CPU A 77 degrees F
    GPU 85
    GPU Diode 88
    GPU Heatsink 85
    Ambient 61
    Memory Cont. 74
    Airport Card 112
    HD Bay 1 76
    I find these numbers to be unbelievable. Especially the airport card. When the whole system seemed to be running hot, the Airport Card said it was 122. It always says something above 100 degrees. The other temperatures also seem out of whack. How can the CPU be 77 degrees after 10 hours of being completely powered down in an office environment that is only 55 degrees?
    Has anyone else run into a similar problem?
    Has anyone else found the problem to be a faulty temperature sensor (and is there a way to reset it, or does it have to be replaced)?
    Overheated? in Oregon...

    Certainly sounds like a case of the left hand not knowing from the right, huh
    Well, I have my call in, and I am getting onsite service to replace the logic board, as per Apple's recommendation.
    I'm reading the other longer thread (171 replies), and it's disheartening to hear how some of the "geniuses" are handling this problem. They can't replicate it by leaving the mac running overnight, so "the problem doesn't exist". Hello! It's *random*! As in, not easy to replicate!
    I'm also a bit disillusioned that the popular Mac sites (TUAW, etc) haven't picked up on this story yet. I emailed TUAW the link to the long thread, and they ignore it. Usually when this gets more "mainstream" press, then Apple finally steps up, acknowledges a problem, and serious fixes are made. Right now, it's a bunch of complainers (me included) in some threads on the Apple site.
    I took a huge leap last November, and went from PCs to the Mac platform, after working on my personal migration plans for a month prior - how to move from my photo editing on the PC to the Mac (I wasn't about to buy another full copy of Photoshop, for eg, but I did find out I could upgrade from Win PS to Mac PS), if all the programs I use for photography and design were available on the Mac, learning the ins and outs of shortcut keys, how things are done, etc etc, and was so happy initially when I got the Mac and said goodbye to the PC.
    Now I'm literally afraid to do any serious work on the Mac for fear of the "pulled plug" syndrome losing the last 20, 30 minutes of work I've been doing because I didn't save every 2 minutes. And iLife's Pages doesn't autosave (much to my chagrin), so I've lost some long correspondence and articles typed because I didn't save it before the pulled plug o' death.
    Not a very nice computing experience.
    As a suggestion, maybe everyone reading this and the other thread can flood TUAW.com with a news suggestion to cover this problem. Engadget, Gizmodo too while you're at it. I think once these million-viewers a day blogs cover it, we'll see some real action from Apple.
    Just a thought....

  • "notes" randomly disappear. Any idea why?

    On ipad mini i keep lots of info in my "notes" but they randomly disappear. Any idea why?

    It could well be that you inadvertently hit the M key while having notes selected. It is the default keycommand for Muting/Unmuting whatever is selected (regions or notes). The good news is: in the piano roll, ⌘-A followed by M solves it, even when not all notes are muted.
    Next time you notice this random muting, look in *Edit>Undo History* to see if there's a "mute note" action somewhere in the list.

  • Why is imac randomly shutting down?

    Hi everyone, My imac 24" intel (early 2009) 2.66ghz 4GB ram keeps randomly shutting down, It started after i upgraded to 10.8.1, It was running fine until then, I had the screen set to sleep if no one had used it for half an hour (not changed this for 3yrs) & it started to not wake up & i would have to restart then when i started using it would randomly shut down like someone had pulled the plug! When i got it going again it would do it again sometimes in 5 mins sometimes 10 mins, I spoke to apple on the phone did all the usual stuff they told me to do still the same, I'm going to the genius store tomorrow with the imac.
    I have no idea what could be the problem.
    Anyone had this before?
    p.s I have had this 3yrs now so no warranty

    Anybody have any ideas why ? Could it be anything to do with the memory DIMMS being incorrectly placed ? I have two 2GB and 2 4GB memory DIMMS - maybe they aren't paired correctly , would that have anything to do with it ? They are not recent additions ( added a week after getting the machine but the crashes have been happening for a long time ).

    Seems like whatever I did, or combination there-of, has stopped the nightly crashes.
    Looking at the report I removed everything that was left from having BlackBerry software on the Mac ( first thing that seemed to crash; re-arranged my memory so that the original 2 x 2GB chips were in the top slots (bank 1 and bank 0) and the larger newere DIMMS 2 x 4GB chips were in the bottom slots; stopped any sharing which were selected in the sharing portion of system settings; ran hardware test and repair permissions from recovery disk.
    For the last 3 nights, no crashes and the iMac has woken from sleep in the morning instead of having to reboot.

  • IMac Random Shut Down Problem

    I having a problem where my iMac will randomly shut down without warning. Doesn't matter what app I'm using. The weird thing is that it ONLY happens after it has gone through a sleep/wake cycle. It doesn't happen after doing a cold start. The random shutdown happens anywhere from 30 secs to 30 mins after waking. I've tried the SMC reset, didn't help.
    It is really starting to be a pain because I prefer to put it to sleep instead of shutting it off. Please help.

    I'm having same problem. Random shut downs are truly random with shut down interval changing from 2 seconds to 20 minutes or more. I've tried everything, including reset SMU, PRAM, disk diagnostics. Disk checks out. I also deleted the com.apple.PowerManagement.plist file, then reset SMU again. No go!
    From what I have read seems like a power supply issue. I guess I've got a good run since buying this iMac in Aug 2005. I read on another thread that www.synaptech.com has reliable replacements.
    If anyone has any other ideas, then please share!
    thanks and good luck!

  • My imac randomly shuts down.

    After a little research, I've noticed this is a fairly common problem.
    Here's where my situation is slightly different. I'm never around my imac when it randomly shuts down. I'm always asleep. It's happened a couple times this week. I was up till 3 in the morning last night and woke up at 9 to see my computer had shut down. I had Firefox open the second time and it asked if I wanted to restore my tabs when I turned it on again (so I know it didn't just go to sleep). Any suggestions? I just did reset the "system management control (SMC)." Hopefully that will work, but........

  • 27-inch / 27" iMac Random Shut down

    SPECS:____________________________________________________________________________
    • 27" 2.8 GHz Intel Core i7 / 8gig / 1TB
    • OS 10.6.3 (about to update to 10.6.4)
    • All firmware updates have been applied according to software update
    • 3 external drives: 1-320 gig 800fw / 1-TB USB 2.0 / 1-500gig USB 2.0
    INFORMATION:____________________________________________________________________
    I've been running with this configuration ( 3 extra drives) since approximately December with no issues. Out of the blue... only running Aperture and Safari - my iMac JUST SHUTS off- WITHOUTwarning. It acted as though I was running a MacBook and the battery going dead/asleep. That's how random and sudden it shut down - NO WARNING. I did have the iMac asleep for about three hours before coming back to it to start working again when it shut down, but it should have even been cool.
    I only started reading around on the web to see of other incidents after this random shut down this evening, but I can't find anything specific. I've found A LOT of similar things - all seemingly related to "HEAT."
    And heat seems to be a certain issue recently - in the last day or two. Today I noticed my top back side to be hot, which isn't uncommon, however, it became so hot I really wasn't able to keep my hand on the top back. I've also noticed A LOT of spinning beach balls, and lots of processor delay! Heat??
    There are NO energy saver pref's set to automatically shut it down. The power was and is firmly set. There are no network settings, nor access to the iMac to have it shut down. It is not shared with anyone on the network.
    SUMMARY:___________________________________________________________________________
    • Today, I grabbed a couple temp / monitor widgets and am trying to watch the data. All components seem to be at/around/below 140 degrees F with ambient air at 77 degrees. I don't know numbers, but that all seems reasonable.
    • Going to update to OS 10.6.4 (doubt that's it!!)
    • I'm going to run the hardware test from my disc to see if ANYTHING. 8-p
    • AND... I'm going to call Apple to set up a case. It's still full under warranty, and I have 2 more years of AppleCare on it. But there's been too many things pointing to hardware to call this a software issue.
    I've dodged all the display issues with my iMac, but now.. I'm a bit hacked knowing how much I spent on this thing, with the initial DELAYS I went through, ordering it before it had even been released!
    ?? QUESTION ??_____________________________________________________________________
    So, has anyone else been having this issue, heard of a solution, seen anything on Apple's website of known issues ??
    Barry
    ( Grumbling bout my Mac)

    First, a precautionary Note:
    Apple "Call Directors" are outsourced, and from what I experienced today are idiots and liars. When asking for Customer Relations the first guy represented himself as Customer Relations. I knew he wasn't. I said he was a liar and hung up on him. The next gal transferred me to CPU tech support, even though I specifically stated "Customer Relations." So just keep your guard, know you're calling and who you're speaking with.
    UPDATE #2:
    I still don't think Apple knows about this issue enough, or they're just not saying that they're seeing it more.
    I spoke with a senior tech support advisor who said he believed it was a heat issue. It could be because the number of periph's I have attached, and that I might try unplugging those one at at time. I personally don't think that's it since I've been running the same configuration for over six months.
    To his credit, the Sr. tech said he wasn't convince of that, nor did he think it was a software issue, although he also suggested as a trouble shooting step - was to do partition my drive and try running an OS from there. Both suggestions kind of defeats the purpose of being able use my Mac and applications. Since this issue has only happened twice, he said he would rather have me trouble shoot on my own some more, rather take in for service and then have repairs not be able to duplicate the issue.
    The last thing I did before contacting Apple today was to do a SMC update, and the Sr tech I spoke with said that that step very well could resolve the issue. I also think the same since I just did the SMC firmware update a little over a month ago, and this issue just started a week ago.
    SUMMARY:
    Sorry... that's all I got so far. I'm just hoping I don't have any more random shut downs, and hope the SMC reset does the trick. I am very interested if anyone else has any better, any more info, any better solutions they've heard or come accross?

  • Safari randomly shuts down... why?

    I could be web browsing, watching netflix, or have the mac closed only to come back to find that all my safari windows had shut down. I don't have very many programs running, I've cleared my cookies, I have no idea why it could be doing this but it's extremely inconvenient. There's no load signal as if it was trying to load something, it just literally crashes. Why could it be crashing and what can I do to fix this? I just bought this mac brand new a few months ago and have all the software updates installed. I have the OS X Yosemite 10.10.
    Any help would be greatly appreciated.
    Thanks!

    (Early 2009 iMac, 2.66 GHz Intel Core 2 Duo, 4MD RAM, OS X version 10.10)
    I'm having the same problem almost every night while I'm asleep. I stream "music to sleep by" from a website every night, all night. Since loading Yosemite, Safari seems to shut itself down sometime during the night (always AFTER I'm asleep, but before dawn). Looking at console logs for last night, I see my system backups running successfully every hour, then something different after the 4 a.m. backup. Note: After this sequence, there were no more hourly backups until I woke the computer manually at roughly 9:30 a.m. — at which point the iMac went through another successful back-up. Console sequence shown below:

  • IMac randomly shuts down still

    Just bought this iMac a little over a week ago. The genius told me to immediately update everything, I did and it still shuts down on me. Any ideas?

    Welcome to Discussions - Exactly which model did you buy? If everything shuts down, I would take it back and ask for another one, there's something obviously wrong. And make sure that when you get a machine that works, you get Apple Care with it.
