IMac completely shuts down while working in LR4

I have an iMac 27 2.9ghz 12gigs ram with a large file of photos (13000+) My computer shuts  completely down witha sudden "pop" when working in LR4 only. Had iMac checked at genuis desk an they put a new powersupply in....but still does the same thing...Is it the program LR4.2 or my computer?

Sorry, this is clearly a hardware issue...LR 4 does (as Victoria mentions) "stress" the CPU. But f you are hearing a "pop" then something is seriously wrong with your hardware (a "pop" indicates that your power supply is toast) your hardware should NOT be making noises...when it does, you really need to look out!

    My imac suddenly shuts down while on line. It has to be unpluged for a couple of hours before it will restart. Could it be the battery dying? Any other sugestions?

    Which iMac..? Go to > How to identify iMac models
    1. Reset the SMC > Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Reset the PRAM and NVRAM > Resetting your Mac's PRAM and NVRAM
    Then test it for a time and report back.
    You also might want to give the Extended Apple Hardware Test a run, as per > Intel-based Macs: Using Apple Hardware Test to see if it turns up a hardware problem.

  • IMac G5 Shuts down while running applications

    I installed iLife '06.
    Since then my iMac G5 (20") has started shutting down while I'm working.
    I'm not sure if the installation is related to the intermittent shut down or if there is another problem.
    Someone told me that the fan might be bad. I don't know how to check if the fan is bad. I've heard that some iMac's have noisy fans. I've never heard the fans on my iMac.
    I've had my iMac for ten months with no problems.
    iMac G5   Mac OS X (10.4.6)  

    There are two common reasons for an iMac G5 to shut-down:
    1) a failing power supply (see the article A. Brody mentioned).
    2) Over-heating.
    I'll tackle the second one.
    All the recent Macs have a protection mechanism built-in. If the system gets beyond a given temperature, the computer will turn itself off (without warning) to prevent permanent damage.
    So, if you notice that the computer is running warm before it shuts-off, then that could be the cause.
    But, it is also very likely to be the power supply.
    And, operating with a faulty power supply could lead to tons of other problems or damage.
    So, I would personally get it into a shop for inspection and repair very fast.
    But, if it is under warranty, you should not have any trouble at all getting it fixed (either standard warranty or AppleCare).
    If it's warranty has expired, see if it is within the covered systems listed in the article A. Brody gave you.
    If so, request it to be inspected and repaired for free under terms of that extension.
    Regardless of which problem it is, get it fixed. Neither problem is one that should be ignored.
    Hope this helps.

  • IMac G5 shuts down while importing HDV video in iMovie

    So here is the problem, my 20" iMac G5 will be importing video from my Sony HDV camera, and will just shut down. I mean turn off completely. It happened 6 times yesterday to my wife. When I try to turn it back on, sometimes it will work, sometimes, I have to unplug the iMac from the plug and wait 30seconds before it will turn on again. Any one have any experience with this? Is it a power supply issue? Any thoughts would be greatly appreciated

    got apple care to replace power supply

  • G4 shuts down while working on it.

    hi
    My G4 mdd lately has been shutting down for no apparent reason. I'll be working on Photoshop, web surfing, etc. and the G4 MDD will just shut off. I read a lot on the MDD having PSU and/or overheating issues. What can I do? Are there fixes for my good ol G4 MDD? Are there PSU replacements that will work?
    web dude

    A hot temperature can cause a shutdown. Suggest you download & install the freeware Temperature Monitor http://www.macobserver.com/tmo/review/temperaturemonitor_4.6_gives_warmfuzzies/

  • 2011 MacBook Pro shuts down while working with blu ray disks

    I am trying to backup my blu ray disks to digital formats in the event that a disk is damaged. I am using an early 2011 MacBook Pro with OSX 10.8.5 with a Samsung SE-506 external blu ray writer. I have been using handbrake to rip DVD's, but downloaded Make MKV to handle blu rays. I successfully ripped one blu ray disk last night. Once before that, and four times after, the computer shut down after failing to read the disk. When it restarts, a gray screen reports that the computer experienced and error and had to shut down. I believe this has something to do with the fact that OSX does not natively support blu ray disks. The disk drive is plugged into one of two USB slots in the computer. The other slot has a USB hub with two external hard drives and some other devices connected to it.
    So far, the computer has failed to recognize the disk, and nothing comes up in Make MKV. The last time I tried, the computer recognized the disk, Make MKV read it and showed the titles. When I tried to rip the disk, the process failed. After another attempt, the computer shut down. This has never happened while using the original disk drive, or while using DVD's in the external drive.
    I spoke with Samsung support, and they have no record of this being a problem. So, where do I go from here? I have quite a few disks to rip, so I am hoping this issue can be resolved. I have searched around, but cannot find any information on this problem happening to someone else.

  • IMac keeps shutting down while in sleep

    I have an iMac G-5 without iSight.......not sure if this started happening after the last sucurity update or installing HP printer software, but now when the computer goes into sleep, it waits awhile and then shuts down entirely, forcing me to turn the computer back on. I uninstalled the HP software, and repaired permissions, but this still keeps happening. Any ideas on what caused this and what I can do to fix it?
    iMac G-5   Mac OS X (10.3.9)   80 gig hardrive which has about 2 gigs left

    Hi,
    I am having a similar problem. I have an iMAC (serial in the range W8435xxxxxx - W8522xxxxxx) and in the two weeks, when the computer is put to sleep it turns off. However, I only notice this in the morning after it has been asleep all night. The problem seems to be far more frequent when I put it to sleep as opposed to just letting it time out and go to sleep that way.
    I have applied all updates and the only modification to the computer is extra ram (from Other World Computing).
    I have seen elsewhere that I can see the computer's reason for shutdown in "system.log". Can anyone tell me how to find that so I can look for the shutdown code there?
    Any ideas?

    Thanks

    Voltage at 24 pin and 8 pin connectors are ok and under the tolerance as I saw here http://pcsupport.about.com/od/insidethepc/a/power-supply-voltage-tolerance.htm
    I will check the other rails.
    Hmmm... starting to suspect that the cause is something else.
    Missed the beeps in the past.
    This mobo (z77a-g45) never emitted a single one.
    Not even at startup when it was ok!
    Oh man!
    The computer was running well and then suddenly screen went black, no disks activity, no keyboard response, no video, no reset switch working. Fans continue spinning.
    Had to pull the plug to stop the fans. Then plug it again but no boot. Just cpu phase led 1 is lit, fans activity and nothing more. No welcome screen, no disks activity!
    I will try to test the ram on another computer.
    Any other clues?

  • Imac randomly shuts down while idle

    I have a new imac 27". Purchased early Sept. about three times in that space I have come to use it finding it shut off. I leave it on sleep all the time.
    Could I need a new UPS.? It is about three years old.
    The console report shows it is looking for something but I don't think that has any bearing on the problem. Once it is up and running, no problems.
    This is the console message:
    "11/6/10 12:49:23 PM ..ButtonManager(164) Looking for devices matching vendor ID=1193 and product IDj=8717"

    Thanks. I just realized that something else seems to be going on here. I have two printers attached to the computer, an HP 6150 all in one and an Epson R1900. I just noticed that the HP was also off. It is not plugged into the UPS but a different strip. I unplugged it and plugged back in and it came back on. Is it possible that somehow the printer is sending some kind of signal to the computer and shutting it down??? Sounds weird but maybe there is a problem with the printer. Maybe I will unhook the printer from the computer and see if that helps. It is so random and happens so seldom that it will be hard to know.
    Thanks

  • My iPad 2 won't charge and it's completely shut down. I've tried pressing the two buttons simultaneously, but nothing works. It's driving me crazy! Any offers of suggestions would be greatly appreciated. Thanks!

    My iPad 2 won't charge and it's completely shut down. I've tried pressing the two buttons simultaneously, but nothing works. It's driving me crazy! Any offers of suggestions would be greatly appreciated. Thanks!

    1. The most efficient way to charge an iPad is with the charger that came with the iPad and having that plugged into a wall outlet. Trying to charge while connected to a laptop often doesn't work because the USB port may not provide enough power.
    2. Once an iPad battery has completely drained it may take an hour or more on the wall charger before the iPad responds. So after an hour on the charger reset the iPad. Press and hold both the Home button and the Sleep/Wake button continuously until the Apple logo appears. Then release the button and let the device restart. You will not lose data doing this. It's like a computer reboot.
    3. If the iPad still does not start up make an appt at the Apple store. It will be far better if you have an appointment rather than just walking in because those with appointments will be taken care of before you are.

    Hi, any sleep settings set up, like put Disks to sleep?
    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

  • I am also having trouble with my cursor freezing after installing Mavericks. Never did it before. I called tech support at Apple and they had me restart computer and mouse together from a complete shut down. So far has seemed to work.

    I am having trouble with my cursor freezing between applications after installing Mavericks. Called Apple on my 3 year warranty and opened a case. They suggested a complete shut down of computer and turning off mouse. Then a reboot and turn on mouse. So far iit has seemed to work. Hope this continues??
    Hope it helps others.

    I think you can solve your problems by removing your AppleID email address from BOTH the Messages setting on your iPhone and the iMessages settings on your Mac.
    On iPhone:
    Settings > Messages > iMessage > Dissabled
    Settings > Messages > Send & Receive > touch the "(i)" < touch "Remove This Email"
    On Mac:
    Open "Messages" application
    Click "Messages menu > Preferences
    Click "Accounts"
    Select your AppleID account
    Under the "You can be reached for messages at" settings, uncheck your AppleID email address and your phone number
    Then uncheck the "Enable this account" setting
    And lastly, ask all of your friends with iPhones to delete all iMessage conversations (blue bubbles) in their entirety.
    To test, send a friend a new text using their phone number (not their email address) and watch the color of the bubble.  If it's green then you are using SMS.

  • 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....
