Intel Mac :: Its Monitor Keeps Shutting Off Every Couple Of Minutes
May 13, 2012Lately my iMac monitor keeps shutting off every couple of minutes. It seems like its in sleep mode but if i move the mouse or press a button on the key board it doesn't go back on. I have to press the power button 2 times to get it to turn back on. When the monitor turns on everything is still there right before it shut off.

IMac Intel :: Unable To Turn On System / General Power Was Turned Off For Some Minutes`
Jul 1, 2009my iMac won't turn on. The day before yesterday happened the same thing, but after a few tries with the power button, it eventually turned on - and all ok yesterday. Both the day before yesterday and today, the general power was turned off for some minutes, but the iMac wasn't running. So now, I've tried to reset the SMC, removing everything attached, but nothing.
At least I can clearly hear the tic tic tic button, probably of the timer, because I set up a schedule to let it turn on at a certain hour. What can I do? It's a white iMac, never had a problem.
IMac PPC :: G5 Keeps Shutting Down
Jul 1, 2012Recently a email link was clicked on and since then my wife has been having issues with her G5 shutting down. Sometimes the box will not completely boot at all and others it will boot up for a moment and then shut itself off.
I have looked for teh Flashback Trojan and appear to be clean. If i boot the box in safe mode when booted in safe mode all seems okay. I have also recently reset the PRAM and have had the machine up for a few minutes and it has not shut down yet.

Intel Mac :: Why Is It Shutting Down By Itself
Apr 10, 2012I have a late 2010 27in iMac and it has shut down randomly by itself 4 times in the last month or so, including twice in the last couple of days. I have 16G of RAM and am only using up to 8G ever. Just to be clear, it shuts down and does not restart automatically. I never have the screen brightness higher than half so I don't believe I am overheating it? I really want to know why this keeps happening.

Apr 1, 2007I have a iMac G5 (Pre-iSight). I just got home and my computer was off, I didn't turn it off and I asked my mom, she said she didn't come into my room. I was posting something on here and my computer shut off on its own. What gives?

Feb 2, 2009I have a refurbished iMac G5 that randomly just shuts off. It makes a little "zzzttt" sound, like something is short circuiting and then dies. Sometimes I can power it right back on and sometimes I have to unplug it and wait a few hours before it will come back on. While it's running, there are no issues. It functions beautifully. Anyone else had this type of problem or can you suggest a solution? Here's the info on it:

OS X :: New IMac 20" Not Shutting Down
Feb 4, 2009I've learned quite a bit from this site in recent weeks as I found it following my purchase of a 20" iMac (2.66 GHz) a month ago. I've got a question for the group and I'm quite certain it's a stupid one so please be gentle. As I do every night, last night I put my iMac to sleep at around 11:15 pm before going to bed. Upon awaking this morning I couldn't get it to wake up. Hitting keys on the keyboard didn't do it, nor did moving the mouse around. I'm not sure if this is important but both my keyboard and mouse are wireless. Power to the other things on my desk was still on so it wasn't a power problem.
Anyway, I hit the power button on the back to see if it had simply shut itself off and nothing happened. I hit it again. still nothing. Finally, hitting it a third time did the trick and the computer roared to life and came on normally. It had never done this before. It had always immediately awakened in the morning upon hitting a button on the keyboard. First, is this common for an iMac to shut itself down? Second, why would the power button be unresponsive? Finally, if the machine had actually not been off (which I doubt very seriously) did I do a big "no no" by hitting the power button to turn it off/on?

Apr 15, 2012After around 10 to 15 minutes of using Safari, no matter what website I'm on, it will suddenly close on me. A message will pop up saying something along the lines of - Safari unexpectedly closed - and will have the options to report, reopen or close. I know it would be useful for me to tell you exactly what it said, but by the time I opened up a new Safari and logged in, I've forgotten what it said, it did however mention "Steinberg" something.

Intel Mac :: It Shutting Down When I Try To Use Any Apps
May 24, 2012My iMac is shutting down whenever I try to open an app. Everything was going fine, then I tried to open Skype and was forced to shut down the computer using the power button (there was no error message, just this message to shut down using the power button). I restarted it and deleted Skype thinking there was something wrong with the app. Then I tried opening Firefox and it asked me to shut down again. And it does it whenever I try to oPen any app.

Intel Mac :: Why Is Computer Shutting Down
Jul 4, 2012For the past two nights, my iMac has randomly completely shut down. I set it to sleep before going to bed. When I woke up, it was shut down. And the weird thing is that it was shut down, and when it started up, no applications or anything were open. Generally, I'll shut down and it keeps everything open and running, then when I turn it back on, everything is where it was. I don't know if I lost documents or anything... or everything. I've never seen this before since getting Lion.Â
I checked my energy saver schedule... I had it set to SLEEP at midnight. But it is never set to shut down or start up. And even if it was, why are all the apps closing when it shuts down?Â

MacBook :: Shutting Down Randomly - How To Prevent From Shutting Down
Mar 23, 2010I have a MacBook which has recently been shutting down when it feels like :/ this all started a week or two ago (well not the shut downs but other issues that I'll get too), basically the fan I think has been knocked as it is bumping the top or something as the whirring is getting loud and it sounds like every now and again it hits something
Also CPU usage seems to be averaging out at 20% for Safari and 100% for HD Video where as it used to be very small amount for Safari and 30 - 40% for HD.
PowerPC :: IMac G5 Overheating And Shutting Down
Dec 31, 2010I don't know if it is a fan or a drive that starts up and runs really fast and loud, then the computer shuts off. I always thought it was the fan, but now am not sure. I have moved it to a place where it is exposed to more air, but that has not seemed to help. Does anyone have an idea or solution to this problem? The nearest Mac dealer is about 80 miles away, so if I can fix this on my own, I would like to try.

OS X Yosemite :: IMac Shutting Down Unexpectedly
Dec 6, 2014I have a late-2009 27" iMac i7 with 8gb Ram and a 1TB HD. I updated my OS to Yosemite soon after it came out. Now, I admit I don't use the computer that often, so it took a while to notice the issues but, we first realized there was a problem in early November when my husband could not download a game (presumably because of the wi-if connectivity issues supposedly fixed in the latest update). It was around a week after he finally was able to download tthe game, that he was playing it and the computer would just shut down out of nowhere. No warning, just shut down and restart with the "your computer shut down unexpectedly" screen.
Now, because it happened so many times, I started to get worried about all of my photos and music that is stored on thIs computer, so I went to do a back-up on my time capsule. This was when I noticed my computer had at some point been renamed (not by any human) to "my Computer (3)" when prior to yosemite (as far as I can tell) it was named "my computer". Also at this point I could not for the life of me get the time capsule to back up the computer as it was looking for "my computer" and all that was available was "my computer (3)". This is when it had been working flawlessly for years. I ultimately had to wipe the TC completely, reformat it and start a back up from scratch. It was for the short period of time that the time capsule was not connected to the computer that we noticed it was no longer shutting down unexpectedly. however, one the TC was reconnected and doing a back up, anything extra that you would be doing (with the exception of web surfing) caused the computer to crash.
So, simple fix, right? Turn off the auto back ups while and try to remember to turn them on every so often. fine , dandy, whatever. However, I have done the latest yosemite update and the wi-if still does not seem to be staying connected, disconnecting every few minutes. Now I'm seemingly having more issues with a game that is well within the limits for my computer and the game will not start.
