Randomly shutting down late 2012 27" iMac, 3.2 GHz i5 processor. 16 out of 32 GB ram (crucial). Tried the PRAM and SMC, both did not work.
Hello, I have a late 2012 27" iMac. Its a 3.2 GHz i5 processor. I originally upgraded my ram to 32 GB and was running like a champ for over a year. Then, it started to randomly turn off no matter what I was doing. I took it to the apple store and they said it was the ram. So I ordered 16 GB of ram from Crucial that matched what they said my computer would need. I got it in last week and installed it and it still turns off randomly. I have tried the PRAM and SMC resets and the computer will run like a champ for 15-20 mins then turns off. I would love any help, advice or possible solutions as I am by no means a computer wiz. Thanks in advanced!
Very true - and the tests they do at the store are far better than the AHT. As well, Apple does not tell you where it puts the RAM - they just tell you to add RAM in the empty slots, LOL. Your About this Mac > Memory should show your two modules next to one another (which, as I've decided to "name" them would be slots 1 and 3 as showing from the top as you are looking at it with all the slots facing you (the bottom being towards the bottom of the display). The odd thing (to me) is that the 'about this mac' window still shows the same arrangement even though the modules are now placed vertically. In mine (with two rows of two slots side by side), it shows the OEM RAM in the top and the additional RAM I added on the bottom (which is exactly how the slots are arranged):
And, one more thought - maybe way off - the late 2009/mid 2010/early 2011 iMacs had problems with adding a full complement of third party RAM (they were ok with all OEM or a lesser amount of third party RAM - that is why mine only has 12 GB rather than the supported 16 GB). There were several very lengthy threads about this; I will try to find one of them which I had bookmarked (I can't find my bookmarks in this new iteration here)...

My Ipod nano 6Th sometimes shuts down when I connect the phones, sometimes it not shuts down, but the volume and standby buttons do not work. If I not connect the phones everything works fine. But with the phones connected it goes crazy. I alredy reset, restore and nothing. If I reset and let the phones connect the up and down volumes buttons start to work. But the power/stand by button don´t. I need to disconect the phones to the power/stand by button starts to works. Anyone already have simmilar problem?
A windows error message appears saying iTunes has encountered a problem and needs to shut down.
let's get a crash log from itunes, and send it to the Apple engineers for a look.
Typically, you'll need to configure Dr. Watson on your PC in order to generate crash logs. Windows start menu -> Run. Type in "cmd". Hit return. At the prompt in the command line window that comes up, type in
drwtsn32 -i
And hit return.
This will create crash logs in Documents And Settings\All Users\Application Data\Microsoft\Dr Watson\. There'll usually be a file in here called "drwtsn32.log"
prior to collecting the itunes crash log, delete any existing crash logs in there. (we want to make sure we send the correct crash log.)
Generate the crash, collect the crash log, and and send it as an attachment to this email address.
in the email to Roy, be sure to include the following information:
- A link to the thread on Apple Discussions where the issue is being discussed
- The username you are using in the thread
- The version of iTunes you are using or trying to use
- the version of Windows you are using (mention service packs)
- A concise description of the issue you are seeing
- The exact text of the error message you are seeing -

I HAVE JUST PURCHASED LES MISERABLES FROM THE STORE BUT TWO TRACKS DID NOT DOWNLOAD. CAN I GET ANOTHER DOWNLOAD FROM THE STORE OR A REFUND? ALTERNATIVELY CAN I DOWNLOAD THE WHOLE ALBUM AGAIN FREE?
Try the Store tab in iTunes and Check for Downloads.
If that doesn't work go to the main itunes store screen in itunes and on teh right side under quick links see if you have a purchased secrion - do the tracks appear there for download?
Failing that contact support:

I was recently disconnected from my WIFI and it wont even budge to turn it back on. I tried the troubleshooting and that did not work. Apple won't connect me to tech support and i could really use help. Please.
Select None for payment method > iTunes Store: Changing account information
If None is not available > Why can’t I select None when I edit my payment information?
Yes, you can redeem an iTunes gift card for current purchases.

"it does not work" means nothing. What specifically is the problem? -
Ipod shut off and home button does not work
So my friends iPod shut off and her home button doesn't work, and if plugged in wont turn on either? We tried the alcohol method but it did not work, anyone have any suggestions on what to do. ( her warranty is also expired)
Try:
- iOS: Not responding or does not turn on
Ignore the reset and when it says place the iPod in recovery mode
Place the iPod in recovery mode using one of these programs:
For PC
RecBoot: Easy Way to Put iPhone into Recovery Mode
or
http://joshuabailey1997.wordpress.com/2010/09/02/recboot-v1-3/
If necessary:
Download QTMLClient.dll & iTunesMobileDevice.dll for RecBoot
and
RecBoot tip
RecBoot may have problems on 64X windows, then try:
Tenorshare ReiBoot – Enter & Exit iPhone, iPad, iPod Recovery Mode with a Single Click
For MAC or PC
The Firmware Umbrella - TinyUmbrella
Installs blootware on PC too
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

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 warrantyHello,
Have you blown the dust out lately?

Another Start Up/Random Shut Down Problem
Ok, so I know there are a million threads aleady about this, but I really cant seem to find someone who has a real good suggestion, if there is any...So I have a Mac Book 512/60GB and have had the random shut down thing happen a few times. One time (today actualy) I couldnt start up. I pushed the button about 5 times and the light came on and then turned right off. I waited a little bit and then it worked. Twice when this happened and after I started up the light for the iSight stayed on and the camera didnt work until I restarted. I was in iChat using Vid chat when this happened. I was thinking about making a genius bar appointment to see what their advice was because my local store seems to be up to date on most things and this seems to be a big problem, but I figured I would check on here first. Does anyone have an actual solution that has worked for them???
Thanks a lot

Mac Book Mac OS X (10.4.7) 2Ghz, 512 RAM, 60GBWell the Genius bar ppl were great as always. They told me they could do it in-store but it would take more than 4 days and it seems that people have been getting theirs back fairly quick. I backed up everything on my iBook and had the macbook shipped to my school, so hopefully it will beat me there. He told me they have seen several of these, but when I tried to get details they seemed a little hush hush and confused. The common agreement from the geniuses was that it was a logic bored issue and thats what he wrote on the work authorization, i also need a topcase replacement as there is obvious discoloration. Im gona assume that they do run additional tests and not just follow what the "genius" says, if it is not the logic board that is causing the probs...right? When I get my macbook will it say the work that was done on it?? Hopefully this will be fixed, because a random shutdown macbook is baisicly a useless macbook when you use it all the time in school.

Several shut downs and SMC resets have not worked.....
Runis my fantastic piece of art - but makes a good use for the noise cancelling head phones I bought a couple of years ago....
- Have just read that my 3rd Party RAM may be the culprit - do I have to remove or is there a solution???

My iMac (27-Inch, 2012) is randomly shutting down
Hello,
Wanted to ask here before I bring my iMac in.
I'm having an issue with my iMac randomly shutting down from what seems like a KERNEL PANIC.
I haven't been able to pin down what is causing the shutdowns/kernel panic.
We usually leave this iMac on 24/7 since we use it with Apple TV.
I started noticing about a month ago coming back to the computer after a few hour I would log in and I would get a window asking to restore my apps because
the computer had shut down due to some error/problem. I will usually submit the report to Apple when asked to do so.
It's now happening much more frequently. I'd say about every hour or so. Even when I'm using the computer after a while it'll start to feel sluggish, almost like a quarter to half second delay for mouse and keyboard commands. Then after about 10 minutes it slows down even more until "POOF" black screen....then Kernel Panic grey screen asking me to press a key to restart. It seems to happen regardless of the application I am using.
At first I thought it was one of my USB hard drives or USB HUB that was causing the issue but last night i unmounted all drives and peripherals (except mouse and keyboard) to see if that helped. Woke up this morning to the same login after Kernel Panic / shutdown.
Repaired Disk Permissions then ran apple hardware test this morning. said everything was working correctly. Problem still persists.
Any help/insight would be greatly appreciated (CPU info + Sys Dialog Report below)

Imac g5 randomly shutting down
i recently purchased a used imac g5 from a computer store for around 500 bucks. I luv the computer, nut it began to randomly shut down in the middle of activity. I took it to the store and the technician said that everything looked fine. of course he ran it for twenty minutes and it did not shut down....get home later that day and it runs for about an hour and shuts down. I have been on it today to test it and it has run for 8 hours perfectly. Is this computer worth keeping? I see the numerous posts about this very problem. has anyone figured out exactly why these units do this, and should i get my money back and move on before i get in to deep?
Hey davie and Welcome to Apple Discussions,
Is this an ALS model?
Well look in terminal and see if there's something in the log. Go to; applications > utilities > terminal. If something's there post it.
Also there's this:

So check for bad caps on the logic board and also in the power supply.

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. -
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. -
Late 2007 MacBook Pro Randomly Shuts Down
I have a late 2007 15-inch MacBook Pro (A1226). It has a 2.20 GHz Core 2 Duo, 5 GB of memory (a stock 1 GB stick and a 3rd party 4 GB stick), and a stock 200 GB 7200 RPM Hitachi hard drive. I have had issues with it shutting down in certain situations.
(1) The laptop shuts down abruptly whenever I pick it up and walk around with it. This consistently happens within 5 seconds of picking it up. I know for a fact that this never used to be problem. I only started noticing this happening about 5 months ago.
(2) The laptop randomly shuts down abruptly when I'm using it on a hard stable surface that does not block any vents. This does not necessarily happen when it is under a heavy load. When it happens, the laptop suddenly shuts down and the screen suddenly goes black. I have to wait about 5 to 10 minutes for it to be willing to turn back on again. This happens one to three times a day, and it is completely unpredictable. Below is a graph of various temperatures up until the point when it shuts down. None of these temperatures are high enough for me to suspect that this issue is caused by overheating.
I would really appreciate it if anyone had any insight into why these random shutdowns are happening. Thanks!I suggest an Apple Hardware Test and see if that picks up any issues:
http://support.apple.com/kb/ht1509
An appointment at an Apple genius bar seems like a good idea. Since you say that the problem occurs when you pick up the MBP, you should be able to recreate it for the technicians.
Though I do not believe that it is connected with yo ur problem, I would suggest replacing the 1 GB RAM chip with a 2 GB RAM chip. That is the best RAM combination for your MBP.
Ciao.
