My 2007 iMac keeps shutting off randomly. I'm running Mountain Lion. I have tried unplugging it from the back waiting and plugging it back in. Sometimes when I have turned it back on, the fan will run loudly.

Each day I am slowed down by spinners. I have more than enough memory (4TB) but my iMac is a bit older. Is there anything I can do to get rid of the spinners and improve the speed?
Info:
iMac, OS X Mountain Lion (10.8.4)
I have had this for the last few days, so I don't really know what's going on...Â

View 5 Replies View RelatedI have a problem with my iMac which is running OSX 10.8.5. I think the easiest way to explain this would be to just give a simple example. For example let's say I have Excel and Word both open. I shut them both down. Then I completely shut down my computer. Power off. I go to bed. Next morning I boot up and guess what? Word and Excel are now running again, just as if I had never shut them them down.

My friends iMac G5 just recently has been randomly shutting down. Does anyone know anything I can do to him fix his computer?
I checked [URL] and there seems to be issues with power on some models, but his serial number just misses the infected batch.
I looked into my issue a little but recently my IMac G5 started randomly shutting down when left unused for a bit but that seems to have stopped as far as I have noted. Now occasionally when it goes into sleep mode it will freeze on the black screen and the fan will go crazy. I plan on buying a MBP, if the update ever comes out, and then ill just completely wipe the IMac and give it to my parents, who still use the original I mac, G3 or something. I read a certain series of I Macs were having motherboard problems, W950 or something, but mine wasn't that serial code.

View 2 Replies View RelatedSo frustrated with this situation. It appears this is only happening since upgrading to Lion so that's why I've chose to post it in this forum. My screen has been shutting off randomly. And I've only been able to get it to happen when I use gestures on the trackpad. (I.E.: "App Expose, "Show desktop" or "Show all windows.) I say my screen because the HD is still spinning, the keyboard backlights are still on and the status light is still lit. I can't do anything but hard shutdown. I've tried adjusting the brightness, clicking, keyboard commands (force quit) and nothing does anything. I've been sending the crash report to Apple but I feel like that is pointless so I'm turning to the forum for a possible answer. I've inluded my specs below as well as a copy of the log that got sent to apple (in blue). I don't know if it will say anything to anyone but it's worth a shot. I don't think it's a screen cable issue cause I'm not moving or adjusting the screen when this is happening.

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.

I recently replaced a failed hdd in my late 2009 aluminum 20 inch. I watched countless teardowns and hdd replacement videos and picture guides before I did this at it was my first mac machine. Not every time, but occasionally when I restart the machine the temp will be some where in between 79- 86 degrees f and the fan will be going at 1500rpm randomly for about 30 seconds and then stops. Other than that everything has been flawless since the replacement.
Did I do something wrong? I put the thermistor correctly on the hdd when I reassembled. What could be causing this as before I replaced the hdd I never heard the fan at all. Mac was bought on august 2, 2009, when hdd died I tried to have apple exchange it, but the wanted to give me a refurbished imac. Since I have had terrible luck with any refurb in the past I just replaced the hdd in it myself.
I am preparing to upgrade to Mavericks. I want to put a bootable copy of Mountain Lion on an external hard drive so that I may run apps that aren't yet compatible with Mavericks.

I've been having troubles with safari shutting down randomly. I went to [URL] to try and reinstall safari. But it won't let me do this because it says this update requires mac os x 10.5.8. or newer. The thing is I have 10.6.1. What should I do now?

I've had it for about 6 years now and always have to have it plugged in because the battery is swollen and won't fit for the lid to stay shut. Now recently it's been randomly shutting off and have to turn it on again. Is it dying or it simply not getting enough sleep?
View 1 Replies View RelatedI have a MAc Pro, Bought in January 09, pretty much stock except for an exta 500 gb drive and the Nvidia video card.
I have a strange problem, I will be using the computer and it will just shut down. Ie my LCD monitor shows the "RBG MODE" screen which it shows during a reboot or if turned on when computers off. My Intelli mouse explorer laser mouse turns off but if I click the laser turns on and off with each click and the power light on the tower is lit but nothing turns the machine off/on unless I hold it down till it reboots.
This has been happening since about the beginning of July, happened last week again every 10 minutes or so it would do this. Saw a post that said it's cause its too hot and its shutting down for safety, I have Istat and the temps at that time was 35 degrees celcius ambient and the processors when watching a dvd or somthing was around 40 degrees, I installed smc fan control and ramped up my fans and with them runing 1500 rpms the temperatures have been steady at around 32 ambient and 35-37 for the vaious sensors. Today the heat wave is over and istat says the ambient is 26, processors and drives are still 35-37 and it rebooted again.... is my machine running hot or is it somthing else.. I am at a loss. It is a Stat holiday here so I cant call my local repair place. Running OSX 10.5.7 any other info is available if needed.
So, for the last week or so I'm been experiencing very strange symptoms, which I think are probably all connected:
1) My MBP (running 10.5.8 bought in August 2008) has from time to time just been turning itself off. Like, I'm just working on something and then it suddenly turns off.
2) My mouse from time to time stops responding to input, sometimes the keyboard does the same thing
3) When I restart after 1 or 2 occurs, it doesn't work. The computer turns on, I get to the screen with the apple on it (there's a chime all of that), then it goes to a plain blue screen and just stays there - the log in box never comes up.
4) In what I think may be related, my computer seems to be running extremely "hot" right now. After just normal use, I'm reaching GPU temperatures as high as 75 degrees according to iStat and CPU temps around 70.
Macbook pro (older style non-unibody) running 10.6.8 has started randomly shutting down instantly for no reason. Sometimes only lasting 30 secs before just shutting off, sometimes up to 10 minutes. Happens when cool or hot, no apparent rhyme or reason. Tried resetting SMC, no difference. Ran software update, thought that had fixed it as it stopped happening for a day, then the problem started up again.

I'm using iGetter version 2.8 and it's great. Downloads are quick, but I have one concern about the program. It randomly shuts down every 5-10 mins or so. The downloads aren't finished downloading and iGetter shuts down.
View 1 Replies View RelatedMy Macbook is 1.5 years old (13in, white, 2 GHz). About two weeks ago, it would randomly shut off. It would restart fine, but shut off sooner. Sometimes, it wouldn't even restart. Now, it's at the point where when I power it on, it rarely restarts past the white apple start-up screen.
My thought is that it is overheating. Are there any more ideas? What can I do to save my macbook?
When my Macbook pro is not plugged in, and i try to watch videos, it shuts down like it dies, even if it says the battery is 90%. Is it a battery issue? Or some other type of issue? Bought it in late 2008..
