OS X :: Mac 10.5.6 Shutting Down Spontaneously?
Feb 13, 2009
My mac os x 10.5.6, (2.8 Ghz Intel Core Duo, 2GB 800MHz DDR2 SDRAM) keeps shutting itself down spontaneously - no error message occurs before or after it shuts down, and when i press the power button on my mac i get no response.
I have to turn it off at the power point and turn it on again.
I have a power surge board and only my mac is plugged into it so i'm pretty sure it's not a surge problem.
It seems to mainly happen when the screen saver comes on, and i have checked all of my system preferences and i havn't selected to turn off hard disk's at any time etc. I have no idea why it's doing any of this!

My iBook (about 3 years old) all the sudden started continuously restarting. The screen would dim and a black window would appear saying that the computer needs to be restarted with a picture of the power button symbol behind it. I have done that and now the same thing keeps happening every time my computer turns back on. It has happened 4 times in the last 20 minutes. One time as soon as it restarted, it shut itself off as soon as the desktop appeared. Does anyone know what this means?

Twice my macbook pro has shut down on me spontaneously. I recently got the logic board replaced. What could this mean? What do I need to do differently?

I 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.

I am having a problem with my Mac Pro waking from sleep spontaneously at night. It doesn't always do so, but when it does it seems to be at the same time, 00:42. This morning I opened console to see what was going on at this time and this is what I got: [Log] So it would seem that eye tv is the culprit. I then went to open the com.apple.AutoWake.plist in the System Configuration folder and found 2 entries for EyeTV under wakepoweron which correspond to the times listed above (i.e. 09/24/08 00:42:30 and 03/31/32 06:00:00). I have tried dumping the com.apple.AutoWake.plist into the trash and then restarting, but a new file is generated with the same entries, and also opening the com.apple.AutoWake.plist to delete the entries, but then get an error saying I don't have appropriate access privileges to save the file (even when I change privileges under 'get info' to read/write I still get the same error message).

Sometimes programs just won't open and the error -10802 (I think that is the number) shows up. I searched it on the mac website but nothing come up. Generally everything runs, but sometimes things just stop opening. When this happens programs that are already open will work (for example if word is open I can make a new document), but things are a lot slower, and particularly in firefox I noticed once when this happened that I was typing faster than the computer was able to show my text. When I restart my computer things return back to normal, but it usually happens again after a few days. What could be the reason behind this error? I recently removed all the music from my computer to make space, and ran an anti-virus program.

My imac has been restarting while I'm away from it, as if instead of going to sleep it just does the restart. Nothing much has changed in terms of usage, i.e. no new software, etc.

My computer has been spontaneously restarting itself. This last time I wasn't even at the keyboard, I was across the room. I don't know what to make of it, completely baffled.

I use the Dvorak keyboard setup as my input source, and never change it. Recently my machine has started spontaneously switching back to the standard U.S. keyboard -- distracting, to say the least, when I suddenly get weird windows opening or gibberish appearing in documents. This has happened in both Mail and Mellel (a 3rd-party word processor) so far. I can't find anything about this problem in the forums; how to re-stabilize my choice, or how to investigate it further?

Machine is an early 2008 Mac Pro. I'm connecting two external SATA desktop hard drives via eSATA (NewerTech Voyager S2 enclosures) and a Newer Technology eSATA Extender Cable (connected to the 5th and 6th internal SATA headers). One of the drives is used as a Time Machine backup disk. This TM disk has been periodically disconnecting and generating warning messages about improper ejection. It reconnects with a restart, but usually will disconnect again within a day. I swapped the drives in the docks, so each was connected via the other dock, cable, and internal header. The same problem persists - the TM disk disconnects periodically despite having switched docks.

Recently (in addition to other seemingly unrelated password problems), files on my desktop became locked. Finder asks for a password to delete them. I believe an Apple Genius said thought this was normal behavior, but we've never had that happen before on this computer (Mac intel core 2 duo v10.7.4) or anyother of our Apple computers, which are several years old.
So, is this suspicious activity, or is this a normal feature of the OS?

I have an early 2011 15" MacBook Pro, and about three weks ago the screen suddenly went completely black. I can't remember what I was doing at the time, but I don't think I was inputting in any way. The only way I could revive it was to press and hold down the power button until the boot-up tune started playing. I thought it was a one-off, but it has now happened twice more. The last time was this morning. I had opened the lid to wake it from it it's overnight sleep, looked at one text document and close textedit. Then I saw I'd received an email, (I always leave Mail running), so I clicked on the Mail icon and opened the message. I was just reading the message -and not inputting- when the screen just went black without any warning whatever. The Apple logo on the lid also went out.Â
I closed the lid and left it twenty minutes to see if it would wake up normally when I re-opened the lid, but no, I had to press and hold the power button to re-boot. There was an error message displayed when my computer came back to life, but it wasn't very informative. It had a complex report log, which I copied and saved, but it means nothing to me. I believe that data was then sent to Apple. I don't remember this happening before I upgraded from 10.6.x to 10.7.4 in mid-May, but it didn't happen straight after the upgrade so I can't be sure it's related.Â

I've been using my MacBookPro (1.83ghz) for 3 days, and today it began acting funky. It has spontaneously restarted about 10 times today. It restarted itself about 4 times in 10 minutes just now. Twice it has restarted as soon as the previous restart completed, before any programs have been launched, and with no peripherals plugged in. Other times it has spontaneously restarted with only Safari open, and with Illustrator CS open. Any ideas about what might be happening? Anyone had this issue? Could this be related to software? Or the 1 gig RAM module I installed?

MacBook Core Duo, Leopard 10.5.5, Keynote 4.0.3
Periodically when I play a Keynote presentation my MacBook will spontaneously restart. I've searched many different forums and found many others with the same problem, but no working fix yet. I have a huge presentation next week and obviously I can no longer trust Keynote to do it (quite a few ugly stories on the other forums about embarrassing keynote crashes in front of large audiences).

Over the past several weeks, occasionally my computer emits 2-4 dongs and then the email sent sound, and then it does it again, and again until I either shut off the wireless connection or shut down Mail. There is nothing visible in my sent mail or nothing that I can see anyway. I have scanned my computer with VirusBarrier X6 with an uptodate definition list and it does not find anything.My console report during this time interval looks as follows... with the mail line at the end of the sequence when I reopened "Mail"  Â

I discovered that a limited batch of folders on several different hard drives had all taken on the same modification date, which was several days ago. It is truly maddening because I keep the contents of may enclosing folders sorted by modification date for critical reasons, and now these spontaneously changed folders are far out of order.Â
To make it more maddening, I'm using a program designed to allow changing of the modification dates, which has been working fine on most of them, to change the dates to the same as the latest date of a folder's enclosed contents, but one of them keeps changing it's modification date to right now if I merely twirl down its "carrot" or viewing arrow in list view!Â
NOTE: I had downloaded and run the Onyx program to fix an issue that OpenPGP had with contextual menus not showing up. Their page recommended running the Automation pane of Onyx as the solution. I just found out that I ran that on the same date as the folder modification date changes. Could it be the culprit, and if so, how and why?

I have a mid-2010 Macbook Pro with a 2.53 GHz Core i5 processor and 8 GB of RAM, running OS X 10.10.1. For the last few weeks, at apparently-random intervals, the machine has been rebooting while I've been using it. I can't tie this to anything in particular that I'm doing. It may go a couple of days before a restart, or it could be like today, where it's happened five times in the last four hours. I've tried resetting the PRAM and the SMC without apparent effect.Â
When the reboot happens, the system first freezes for roughly 30 seconds--the mouse pointer won't move, it's unresponsive to keyboard input, etc. The system then appears to power down--the screen and external monitor go dark, fans stop, keyboard backlight goes out. A few seconds later, it powers up, gives the boot chime, and goes through the normal boot sequence. At no point does it give the "your computer was restarted because of a problem" message, and I don't see anything in the Console app that looks like a kernel panic.Â
About two years ago, the logic board was replaced to address a somewhat-similar issue--the system had been freezing and could only be recovered by a hard power off (holding down the power button for several seconds). Â
I'm not sure where to start looking for the cause of this problem, since I can't figure out anything in common with the circumstances surrounding the reboots.

My MBP (2007 intel) freezes or spontaneously shuts down and crackling comes from the speakers. Sometimes this happens together all at once? It happens with and without peripherals.It does not seem to be linked to a specific program or peripheral use.Â

I have a fairly new Mac about 1.5 years old. Recently I am having an issue with it shutting down periodicly for no apparent reason and then it starts back up> I have noticed it does do this by bumping the desk or hitting the screen but it is only every so often and can't duplicate it by trying these things.

I use Daylite and Daylite Server on my MBP connected to the net and sync my iPad running Daylite Touch through my 3G connection. It works great while I have my MBP running. I want to set up my MBP so that it will run without shutting down (screen blanked out). I just want to do this for a few days to see how it works out. If I like it I will get a Mac Mini to run as the server instead of the MBP.
The problem I am having is that no matter how I adjust the settings on the MBP, after awhile it shuts down Daylite and Daylite Server. Daylite Server shuts down and puts out an error message and everything just hangs there. I figure I must be doing something wrong in the settings but don't know what. I tried searching the forums, google, apple support, etc. but haven't found anything - of course I am probably searching all those wrong too.

About 10-15mins after starting a WoW session in 10.5.6 on a Mac Pro, the screen goes into powersave mode, and cannot be returned. This is leaving me with no alternative but to hard reboot!
I can hear the fans going mad as I'm playing, so wonder if it's a heat issue. If so, what to do about it?
Can anyone suggest:
a) How to break out of screen power save without hard rebooting?
b) What the issue may be and how to investigate/resolve it?

When im playing a game in bootcamp, my computer just randomly turns off. I thought it might be from overheating, but I started using a cooling pad to try and help, and it shut down almost right away the next time I went to play. It happens occasionally when im running osx, but not nearly as often.

After I bought it, I noticed that the fan was making loud noises when I used it too long. I know it is normal for it to overheat after a long period of use but it doesn't just overheat, the fan starts making a weird grinding noise. I thought that it was just dirty and it wasn't affecting the way my computer was running, so I just ignored it.
It has been almost a year now since I first bought it used and the fan has gotten a lot quieter, but just starting last week I was watching a movie on Netflix and right in the middle of my movie, the computer just randomly shut off. I figured it was overheating. But, even after it had cooled down, I went back to watching my movie and within 10-15 minutes, it did it again!

I 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.

When I woke up this morning, I went to use my new Mac Mini. For some reason, it will appear on the monitor for about five seconds, and then nothing will show on the monitor at all. Attempting to restart the Mac Mini only finds it doing the same thing.

Recently 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.
