Software :: IMac Shuts Down At Start Up

This has been a great computer - bought new in 2004. Recently started to click "off" as it was just powering up. I thought there was a bug - so did a clean and install for OS X - but still does it. The only way to start computer is to hold the Options & Alt key and P and R key at start up until I hear 6 dinging noises of start up (why six is the magic number I don't know. But it is the only combo that works!). Once it is up and running no problems.

OS X Server :: Computer Shuts Down - Right After Start Up
My comp. has worked perfectly, Then I installed some updates, Itunes i think? And the comp. Shut down, and when it restarts it works for a min or two, then freezes, and i get the beach ball, that just spins around and around forever.

if I don't try to open anything, or do anything when i restart it, it will just shut down, and restart, then when it comes to the Grey screen with the apple and the little circle below it, the circle looks all pixilated, and just freezes

that is the version its on (Taken two days ago, and sent to a buddy for other reasons completely)

MacBook Air :: It Shuts Off And Cannot Start
I have a late 2010 MacBook Air.Unfortunately, I'm in a country without an Apple store or any kind of official Apple support (no phone number to call).

2 days ago, I plugged in a little USB modem device (wireless is rare here) and my laptop shut down suddenly. It refused to restart at all until I did an SMC reset and then it was working fine (including with the USB modem plugged in).

However, the next day, the same shut-down occurred (when I plugged in the modem again) and now SMC reset is not doing anything. I've held down the start button for a very long time and there aren't any signs of life. The light on the charger shows that it is charging when I plug it in.

Power Mac G5 :: Shuts-down A Few Seconds After Start-up?
I've got a strange issue with my PowerMac dual 1.8GhZ and I can't figure out where it's coming from.Last Saturday I experienced a Kernell Panic while using Safari and the Dictionary (MacOS 10.5.1).Since then, whenever I try to start my computer, it shuts itself down while the grey screen with the Apple logo is on screen. However, this isn't always the case:I can use my computer 'normally' if I press the option key at start-up and manually choose my startup disk.

I can boot from a Panther or Tiger installation disk, but not Leopard.If I try the hardware test the computer shuts itself down in the middle of the test.TechTool works and didn't find any issues with my computer. Nor did Disk Utility.I tried to erase both my internal hard-drives and do a clean install of Tiger, but the problem is still there (I have to press option at startup).I tried to reset the PRAM and Cuda/PMA. Doesn't resolve the issue.When I tick 'Restart automatically after power failure' in Energy Saver my Mac will indeed restart, meaning it thinks there was a power failure.Any idea what it might be? And why it only happens in certain situations?Do you think it's a hardware or a software issue?

Desktops :: Mac Attempts To Start Up And Automatically Shuts Down?
My Mac attempts to start up and automatically shuts down on it's own. It continues to start and stop for several minutes and finally boots up. Once it's up it works OK. I've had it in to the Mac store and they tell me it's probably the power supply, but after leaving it on all weekend it seemed to work OK so they didn't do anything. After I brought it home it is still acting in the same way. It's only on trying to start up that it cycles through the start - stop action. Once I turn it off it's the same problem on trying to start again. Does this sound like a power supply problem?

Mac Pro :: Shuts Down Instead Of Sleeping Then Needs To Be Unplugged To Start Up
This is a new problem, started immediately after moving the computer gently a foot to the left...

When computer goes to sleep it shuts down.

Then when I press the power button I hear the mechanical click but it doesn't power back up.

Then if I unplug and re-plug it'll start back up. Happens every time like this.

I've, reseated the RAM chips, repaired permissions and reset SDC (SMC? whatever you call it when you hold the power button in for five seconds after unplugging).

Power Mac G5 :: Shuts Down On Start Up When Sound Card Connected
I have been using my Focusrite Saffire soundcard with out any problems for the last year or so. Then all of a sudden last week I turn on my mac, it chimes but then half way through start up it clicks and turns off! Without the sound card attached it will power up and work fine but why if I've had it working 100% for a year or so with no problems would it do this now? I have not installed any updates, new software or hardware lately and I've done all the fixes I managed to find online (replaced internal battery and plugged sound card into it's own power supply so it doesn't draw power from the mac) but still I get the problem. The only other issue i see is that the digital output on the mac is lit up (red) I never use them so I don't know why that is active, but I also have no idea how to switch it off.

Power Mac G5 :: Dual Shuts Down Unexpectedly - Can't Start Up
I seem to be having the same problem as many users, where my G5 shuts down by itself at random times. My problem started with the G5 shutting down at night. Prior to that, I had come home on several occasions and the G5's fan was in 747 mode. I had to force shut down the G5, which was unresponsive. Then it would go for days without a problem. Eventually the shut downs came more frequently and now it shuts down during startup every time. Consequently, I can't even start up the G5 to check logs or run DiskWarrior, etc. Since every post on this issue seems to have gone unanswered, I am beginning to think my only option is to buy a new iMac. That said, I'd rather not spend the money in this troubled economy and would like to find a fix. Here's what I was able to do so far:

Reinstalled OS 10.5.8 combo updater
Reset PRAM
Replaced PRAM battery, reset PRAM
Repaired permissions
Unplug G5 and plug in after 30 sec
Attempted boot from TTP5 DVD (still shut down)

If I back up or clone my system HD, would I be able to retrieve log information from it (attached to another Mac, I assume)? Is anyone aware of this problem being solved for any other user? Has anybody recently taken up this issue with Apple? How did they handle it?

Fairly new MacBook Pro with OXLion. When I try to turn on the computer, the startup noise and screen appear (grey loading screenwith apple icon). A loading bar at the bottom of the screen fills about a third up, then the computer shuts down again.

MacBook :: Unable To Use System With Battery / Computer Shuts Down Hwen Start From Battery
My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.

When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.

IMac Intel :: IMac Just Shuts Down During IDVD Build
4 week old 20 inch iMac just shuts down during iDVD build of a dvd. Its really weird, because it is rendering and encoding and all of a sudden it just shuts down without a know. Then when I turn it back on it ejects the blank dvd out and starts. I had my SuperDrive replaced also like 2 days ago from the apple store. I have pasted the system.log if that helps?

IMac Intel :: IMac Shuts Down Spontaneously
I have a brand new iMac, mear 2 weeks old. I am totally new to mac and so far i am reasonably happy about everything.but my mac shuts down spontaneously on a regular basis.I have the quad core 27-inch: 2.8GHz iMac with a total of 16GB of Memory now I havent touched the hardware myself it is all as its been since being bout through an official retailer.the shutting down usually occurs when im simulating something in MATLAB, now these simulations can take a huge bite out of the processor and the memory but i would still not expect my computer to just turn off.I've looked around and have come to the conclusion that spontaneously shutting down macs are not the rarest thing on the planet, but i have not really found anything useful.

I installed a temperature monitor that was suggested in one of the threads i read but that shows me values that i dont consider off the chart (however i might be thinking too much in PC terms)during my simulations the temperature can go into the top 60s (°C) but that does not seem unreasonable to me.the whole mac does seem to become subjectively very hot when i touch it on the back around the sides and top, but im not sure how "normal" that i say im very new to mac and OSX therefore i have no idea where to start looking for solutions. the console log doesnt give me anything that i consider valuable information concerning the spontaneous shutdowns but here too my knowledge of osx is limited at best...

but overall im sure you will agree that this is not a desirable situation.i will undoubtedly be Simulating a lot and complex stuff over the next years and i can think of little that is worse than coming to work after a weekend to see my mac just off instead of showing me my simulation results.if matlab told me, dude you're out of memory, that would be fine but it doesn't the mac just shuts down, no warning no saving no does anybody have any idea what might be the cause of this. or what i can do to improve the situation..

additional info, sometimes it will shut down right as soon as i hit run in MATLAB (when the temperature monitor tells me 54°C) sometimes it will do it at an arbitrary time during the simulation, but it has also happend while matlab was not actually simulating anything...

IMac :: Shuts Down By Itself?
My iMac (21.5") turn off by itself and it doesn't turn on until I unplug the AC from the back and let it rest for at least half hour!!! If I try to turn it on I only get fan and drive noise but no screen at all... The longest time I let it rest, the more time that I can use it. I already reset PRAM. I'm runing 10.6.3 and the biggest software I use is ArchiCAD 13...

Does anybody have a similar issue with his/her iMac?

PS. Sorry, I don't speak/write good English but I did my best...

I recently updated to snow and since then have had problems turning off mac. I've reset pram, tried unplugging externals, tried logging out, then shutting down, but every time I hit apple-shutdown it goes black, and reboots. I can put it the screen to sleep with hot corners, but never turns off unless I manually hold down power.

Desktops :: G5 ISight IMac Shuts Itself Down (OS 10.5.8)
Have a 17" G5 iMac iSight (OS 10.5.8) that works normally for several hours and then the CPU temperature suddenly spikes and the computer shuts itself down. When I check the Temperature Monitor (application) history graph, it shows normal temperatures and then a spike. There are 3 fans and I don't know which is failing or whether there's something in the temperature sensing that's gone haywire. My only solution is to do a forced restart. By this time, things have cooled and it will work for several hours.

PowerPC :: IMac G3 Shuts Down During Boot
I have a 700MHz iMac G3, which froze during DVD playback and it needed to be rebooted. Now it will not boot, the gray screen comes up with the loading circle, but it will just shut down after about a minute. I have reset the PRAM, PMU and it is running 10.4. No beeps or anything when it shuts down, it just turns off.

IMac :: Shuts Off Immediately After Powerup?
Sometimes when I turn my iMac on, it'll start doing its thing�light comes on, chime goes, fan whirrs, but then it'll make a strange click/"werrrrh" noise and turn off.It's happened twice to me since I've brought it home from school and each time I just tilted the monitor around while turning it on and it worked.I have been avoiding turning off / restarting my computer because I'm afraid its going to happen and I won't be able to get past it.Could the powersupply be loose or something?

IMac :: No Warning - Just Shuts Off - Overheating?
I've been having trouble with my new iMac that i purchased recently (26th of August actually). Whenever I'm doing something CPU intensive, the machine just shuts off, but usually it's not right in the middle of whatever I'm doing, it's after I close the application. For example: I was playing SimCity4 the other day, pretty old game to cause this problem I would think. As soon as I exit the game, the system shuts off. No warning, nothing, just shuts off. This will happen when i close VMs (it actually happened yesterday while I was running the VM), etc. So I've reset the SMC/PMU, PRAM/NVRAM, and I've even reseated the RAM. Still the same problem. I've taken it in to a repair center in town, hoping I'll get it back by the end of the week. Does anyone have any idea why this would be happening?

IMac PPC :: G3 Randomly Shuts Off
I have an old iMac G3 (400mhz slot loading) that I got second hand for free. When I first got it, it seemed to work perfectly in every way, but the hard disk wasn't very big so I tried to install a new (larger) one. Everything seemed to go fine, but after the upgrade, the computer would only stay powered on for about 10 minutes before shutting itself off. I assumed that it was a problem with the hard disk, so I put the old one back, but the problem persisted. It will only stay powered on for a maximum of about 20 minutes before blinking off and then it has to sit for a while before I can get another 20 miutes out of it

IMac Intel :: Pentium Starts Up And Then Shuts Down?
My son turned off my iMac (Pentium and running Leopard 10.5.6) by shutting off my surge protector. When I attempt to turn it back on, it starts up, transitions to the gray screen with the progress wheel and then completely shuts off. It does not progress to the blue screen. The fans all sound normal.

I have attempted to boot in safe mode, from a CD, a firewire hard drive, and have pressed the option key (which only gives me my internal hard drive).

IMac Intel :: Unexpectedly Shuts Down With No Warning
Last year I bought the new Aluminum iMac and was really excited about it. It came with tiger, the one before leopard, but included the upgrade disc, leopard was just released. I turned the machine on, played around for a few days then decided to upgrade. It would go through the setup then just unexpectedly shut down. I was new to macs so I figured it was restarting or something. I turned it back on and nothing had changed.

I tried several more times having the same problem and each time it would shut down sooner than before. I packed it up and took it back. They switched it out with a new one and it worked well for quite a while but now it's doing it again. in the middle of anything I'm doing it'll just shut off, losing all my work, with no warning or error messages. Its Not Energy Saving function either. Can I take it in to the store if I didn't by anything extra (apple care plan) and it's within a year?

IMac Intel :: Suddenly Shuts Down Completely Quite Often
I am working (trying to work) on a brandnew 24" Intel iMac (2,93 GHz Intel Core 2 Duo, 4GB DDR3 RAM, OSX 10.5.7), scurrilously it quite often suddenly shuts down completely. It happens while sending an email, dropping some files, open FCP or similar unexciting actions. Our local MAC support made a 2 day endurance test, and send it back to me. Their comment: no errors found, returns unrepaired! Thereafter we made an Apple Hardwaretest, as well - no errors could be found. But proven fact is, it shuts down about 5 times in 2 hours. Right now the machine is useless to us but we need it.

IMac Intel :: Automatically Shuts Down And Not Restarting
Recently, my iMac has taken to suddenly shutting down by itself without warning. If I then press the power button, nothing happens. After leaving it to 'cool down' for a while, it will then restart in the usual way, only to shut down again after 30 mins or so. I have already tried doing a SMC and PRAM reset, and repairing disk permissions, with no luck.

IMac Intel :: System Shuts Completely Off On Its Own
My daughter has a 2009 21" iMac she got last fall. She called yesterday and said that twice when she went to use it, it had shut completely off. Had to push the power button to turn it on. No other obvious issues. Her fans seem to run louder than mine is the only thing I notice. We have run disc utility and checked the energy settings. She is up to date on all of her software. Everything else seems to be ok. She does have it plugged into an older power strip. Could that be it? What kind of things can we check from this point?

IMac Intel :: System Shuts Down After About 30 Minutes
My IMac shuts down after about 30 minutes. I ran a hardware test and the report was everything is working normally. I also ran a program that measures the internal temperature and here are the results:

Ambient Air 77F
CPU A Heatsink 93F
CPU Core 1 90F
CPU Core 2 91F
Graphics Processor Chip 1 108F
Graphics Processor Heatsink 1 106F
Graphics Procesor Temperature D 111F
Hard Drive Bay 1 95F
Memory Controler 95F

Are these results within normal limits? Any ideas what my iMac would be shutting down if the report I ran says all hardware running normal?

IMac :: Randomly Shuts Down - Instantly Reboots Itself
I do not have AppleCare on this machine. I've got a 27" iMac that will randomly shut down, be it in the middle of playing music on iTunes, while I'm typing a document or while the machine is simply in screensaver mode doing nothing. Usually the machine tries to instantly reboot itself. All too often, it cannot be rebooted and I have to let sit for quite sometime before it will even power back on. Lately the problem has gotten worse, almost never reboots by itself.

Finally, in the last few days, it just won't turn back on. Nothing. My biggest concern is that I have an unreleased music album from an instantly recognizable major client on the iMac's hard drive, not due out for many more months and still unannounced. I can't simply take the computer into an Apple store for troubleshooting as those files are worth and could cost me exponentially more than even a new iMac outright ever would.

PowerPC :: IMac G5 Shuts Down During Sleep Mode
My iMac G5 (rev A) shuts down immediately after i put it to sleep mode after just starting up the computer. The longer the computer has been on before I put it to sleep, the longer it takes for the computer to shut down while in sleep mode.

IMac :: Suddenly Shuts Down - Screen Warm
I received my new iMac on May 20. It is a 3.06 with an ATI card. I have not had much time to use it until this evening. I had been been setting up some bookmarks in Safari and then was working on a spreadsheet for about an hour when it suddenly shut down. The power strip in which it was plugged in still had it's light on. The iMac is the only item plugged into the strip. I then felt around the screen, the bottom section was cool but the top was rather warm.

The temperature in the air conditioned house is 71�F. Programs open at the time were Safari - which was on an idle screen as I had logged out of a site. Two sessions of Finder Entourage Excel - which I was actively using. Is this an over temp shutdown? I recall some people posting the temperature of their Macs. Are there any monitors on the iMac to see how hot it is running? There were no warnings that it was going to shut down.

Software :: IMac Shuts Off At Random And Not Reboot
I have a G5 iMac, 1G ram, with three external HD, a MIDI keyboard, and an all-in-one Canon print/copy/scan, running Leopard. Lately, my iMac has been turning off seemingly at random, like someone has hit the power strip (although other things plugged into the strip stay on). Sometimes it will reboot when I turn it back on, sometimes not. When it doesn't, it will get partway through startup, then turn off again. There is no apparent pattern to the point during startup where this happens, it's different every time. Sometimes, it barely spins the HD before going dark again.

I took off the back and checked the power supply LED. It says the power supply is OK. I rebooted via the internal power button, and everything was fine for a couple of days. I set the preferences to "reboot after power failure" so it will reboot when I'm at work. I can go through the Time Machine backup list and see how many times it shut down and rebooted during the day (TM backs up once per hour, so when there is a significant length of time between backups, I know it shut down for awhile). The only recent addition is the installation of MoneyWell software, but this app isn't always running when the comp goes black.
