Mac randomly shuts down while using imovie

VERSION
iMovie 10.0.6
ISSUE
While editing movies in iMovie, the screen suddenly and unexpectedly goes black. There is no way to get the screen back on, the power button does nothing. The only way to reboot the computer is to unplug/replug the AC and start all over. All work used prior to the black out is lost.

does a screen display "you need to restart your computer" in about 6 different languages, or does it just shut off? If so, you may have a problem with your fans. I would recommend running the AHT.

MacBook Pro randomly shutting down, while plugged in

My MacBook Pro has been randomly shutting down, while its plugged in and with full battery... I just replaced my battery a couple months ago so it isnt, or shouldnt be, a battery problem... anyone know whats going on?

Same is happening to me. It's only doing it since updating to Leopard.

Macbook Pro random shut down whilst using battery

My Macbook Pro randomly shuts down whilst using battery power even though their is plenty of charge in the battery.
Any ideas??

does it do it when plugged in?
Also it sounds that there's a power failure and causing it to shutdown, I would get it serviced asap, the battery connector might be faulty.

Macbook randomly shuts down while in use. still has batter power.

About six weeks ago I posted this same problem. It seemed to go away on its own but now has happened again (once today and once just two days ago). I couldn't find any thread that had the same problem as mine.
I have a Macbook that I bought in January, 2007 and I've had very few problems with it. Starting last early spring, after a little over a year, the battery started taking less time to run out. It also occasionally took a longer time to come out of sleep mode, usually only a few extra seconds but a few times it took nearly a minute, and once it was nearly ten minutes). I know I need to replace it, but overall, it isn't drastic. It just runs out maybe 25% faster than it used to (and hasn't really increased since), and rarely has problems with coming out of sleep mode.
Three times now my computer has randomly shut down for no reason while I was doing things. Once in August and twice in the last couple of days. It isn't related to a particular program, as I was never always using the same thing. The last two times (today and the other day. And I think the first time, too, though I can't remember), I had my computer unplugged and it had been being used for some time unplugged (once it was around 50%, once around 40%, when it shut off). When I try to turn it back on, it just shuts off again and only stays on when I plug it in again.
I am UP TO DATE on all programs. Is this a common symptom of a battery dying? I'm wondering if maybe the gauge that tells me my battery power is screwed up somehow and isn't giving me accurate numbers (though when this happens, the lights on the bottom still appear as if to say I have battery power left).
Basically I'm wondering if this is a simple battery problem I can solve by buying a new one or if there is a more serious problem with my computer. IS THIS NORMAL? Please help. I love my Macbook.

Mine does that. Around 40-45% battery life it just dies.

MacBook randomly shuts down while watching streaming video

I've been having a problem lately with my MacBook randomly shutting down. I initially thought it was due to overheating which was logical considering I was using my MacBook in bed and the computer was very hot when it would shut off, but I've recently started using a TV-Table top for it to sit on when I'm using it in bed. My MacBook continues to shut down and the computer isn't nearly as hot as it was prior to using the TV-Table top, it is just warm. It's definitely not a battery issue because this happens when I'm using the power source as well. *I think I've noticed that this only happens when I'm in Firefox watching online streaming video on sites such as YouTube.* I never use Safari so I'm not sure if the problem would occur in Safari or not. I tried installing the MacBook SMC Firmware Update v1.1 but it said my computer didn't need it.

I have the same problem, every once in a not-so-blue moon my macbook pro shuts down while streaming video. It only happens when streaming video. Just watched some of the new south park episode, and it shut down on me! It really ticks me off!!!!!

My 2008 15in macbook pro randomly shuts down while in sleep mode. What can I do?

I have a 2008 15in macbook pro that when it goes to sleep it will randomly shut down. Most times when I try to wake it up from sleep it will just shut itself down as well as when I close and reopen the computer it will just shut down. When I try to turn it back on it generally takes 2 to 3 tries to get it to finally come back on. What should I do? I think it might be a Hard Drive problem. Anything helps!

Hello californiabears and welcome to Apple Support Communities,
Try resetting SMC:
http://support.apple.com/en-us/HT201295
If you think you have a HD problem look at the HD in System reports:
Apple menu - About this Mac - More Info - System Report - SATA
Under SMART status does say "verified"?
Otherwise:
Using Disk Utility to verify or repair disks - Apple Support
Is that the original disk from 2008? If so it's due.

Mac randomly shuts down

Whenever my mac is NOT plugged in, it will randomly shut down around 30 minutes during use. It has full battery life and the software is up-to-date
Macbook 13 inch
10.4.11

Yes the fan is running. That's actually why I wanted to put it to sleep - it is so loud!
Any other possibilities? You don't think its on its way out do you?

MAC AIR SHUTS DOWN WHILE STREAMING

My MacBook Air shuts down while streaming video. I am using safari and it works for a while but then shuts down and will not restart for quite some time. When it restarts I have to immediately close the video window or it will shut down again. I have the latest version of flashplayer.

This sounds like an overheating issue. Flash requires a surprisingly high level of resources. Do you hear your fans running at all while you are playing the videos?
Download the free iStat Pro widget directly from Apple:
http://www.apple.com/downloads/dashboard/status/istatpro.html
It will show you both your fan speeds and temperature. Start playing a video and let it play for a short while (sometime before it typically shuts off... but long enough to let things warm up). Then check the temp and fan speed. Do this while the video is still playing as things can cool off pretty fast after you stop playing the video. Post the numbers back here.

Randomly shuts down while asleep

My dual G5 randomly shuts down at night for no apparent reason. I have reset the power management, but it still continues. It might go a week without shutting down at night, or maybe every few days. ONe interesting thing, I have Quickeys installed, but not open, yet the F4 key set to "sleep" functions without Quickeys being open? I have not set any key to shut down.
Any suggestions as to where to look would be appreciate.

I have the same problem. My quad G5 will shut down when asleep. There is nothing about this in the log. One log suddenly stops and then there is the log of the startup. Here is a part of the log from the last occurrence:

Aperture shuts down while using crop tool

My wife is having problem with Aperture. Narrowed down to that it occurs when cropping a photo. Aperture just shuts down and asks if you want a restart. If restart or say no and launch, it recycles to shut down again. If you are fast and change projects as it starts, it will open and operate OK until you go back to that project that caused the shut down. It is not consistent to only one project (equal opportunity) so it appears it has something to do with the cropping tool. Work around (getting old)... delete image that was cropped from library or rebuild all from vault. Neither causes extended remediation.
Have run disk warrior. Asking before I uninstall and reinstall Aperture.
Thanks

I use Aperture several hours each day, and Aperture would sometimes crash while I'm trying to crop and also browsing through images. When this happens, I usually have to restart my machine to get Aperture working again without crashing, I've yet to find any permanent solution.
I think it happens more often when I'm working with large files (the images that have been edited in Photoshop and saved back to Aperture, 72MP files), but I have seen it happen to my plain RAW images as well (12MP files), but it doesn't happen as often as it would with the Photoshop files.
I really hope they resolve these issues soon...

Itunes shuts down while using

When in iTunes if I try to change info such as song name while in the music library I get a 'send error report' messege and iTunes shuts down. I acctually I don't have to change anything just click in the field and when it turns blue which indicates I can start typing I get the windows error box pop-up. This started after the update 11.1.0.126 but I just saw the problem today as I rarely need to rename a song or other data.

Try this and see if it helps.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Macpro 17inch just shut down while using. Tried removing battery and SMC to no avail. Have had this problem before over the last six months but would always restore. Now you just click on the power button front light stays on for 2 sec

Hi, My 17 inch Mac pro laptop just shut down and I can't get it to turn on again. This has happen multiple times over the last six months. Looked through the forum and tried removing the battery and resetting the SMC control to no avail. I was having issues also with the screen a month ago but that resolved by itself. When I took it into the genius bar for screen problems I was told I'd probably need a new CPU board because the vram may be going bad and they just don't fix that
problem. Have held off because of a potential $500 repair and awaiting ivy bridge technology. Does anyone in the community know how I can restart my portable. Right now you turn on the machine and the front light stays on for 2 sec and you hear the machine click off?

I think you may have already been told what the problem is. However look at this and maybe it will help:

Probably another genius bar appointment is the best way to exactly define the problem.
Good luck.

Itunes randomly shuts down while updating ipod

After i plug in my Video Ipod to my computer, Itunes recognizes it and begins to Update. After around 20-30 seconds of "updating" A window pops up saying..
" iTunes has encoutered a problem and needs to close. We are sorry for the inconcenience.
If you were in the middle of something, the information you were working on might be lost"...and so on
At first i thought there was a problem with iTunes, so i tried updating my Nano..and THAT WORKED!
So then once again i kept trying to update my Video ipod..but the same problem kept happening ( iTunes would shut down )..I thought if i restored my Video Ipod then it would work. However when i restored it and tried to Update it, iTunes would shut down again while its updating.
now, all the songs on my video ipod are deleted and i can not get the songs back on it.

I ended up just redownloading iTunes 6 and it works now. No word on how to actually solve my problem via iTunes 7.

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
Judy
