I was unsure where to post this as it could be either OSX or hardware that is the problem. I am currently unable to shutdown my 2008 Alu iMac. Everytime I shut it down, it restarts instead.
After a little bit of searching the forums/google, I understand that this may be something to do with a driver or application that is refusing to close properly - but have no idea how to try and identify what may be causing it.
I have my iMac scheduled to shut down everyday at 12:30 am. Sometimes it will shut down and sometimes it won't. I've only had my iMac for about a month, but am I missing something here? Why won't it shut down automatically.
I had it scheduled to shut down at 12:30am, and I was already asleep. I woke up about 3am to get a glass of water and I checked my iMac and I was able to wake it up. What am I doing wrong, why won't it auto shut down?
i have an imac with 500gb hdd 3.06 ghz and 4gb ram, im running os x 10.6.4 snow leopard. every time i go to shut down the whole computer freezes i cant click anything, all i see is the wallpaper and nothing is running when i click shut down.
View 11 Replies View RelatedMy iMac won't shut down completely any more.It gets to a white screen and then freezes, and I have to hold down the power button to get it to shut down.I have also been getting intermittent kernel panics, maybe one every 3 or 4 days.I went through all of the troubleshooting steps to try and figure out the cause, with no luck. Did a new install of Lion and everything seemed OK for a few days, and then started having problems with programs not responding, not being able to shut down, and now getting kernel panics again.Considering completly formatting the drive and starting fresh with everything, but not sure if that would solve the problem either.

I have one of the 20" iMac G5's covered by the warranty extension for the intermittent shutdown problem. The problem is that I am out of the country, and where I am has very unreliable Apple service. It would be gone for weeks and weeks. I am considering flying back home to get my computer repaired. The computer shuts down multiple times a day without warning.
What are the chances I can find an AASP in the DC area who can do the repair in a day or two. I have read that the repair is only a power supply swap and can be done in 15 minutes. What do y'all think?
My other option is to just buy a new computer and worry about repairing this one in a year or two, which is a $2,000 hassle.
I know this has been discussed before, but I cannot stand that there is no option to shut off the screen. I know the Shift-ctrl-eject (not sure if I got this right, I'm at work now) works to turn off the screen, but I'm facing another issue.
At night, I frequently record shows on Eye-TV and export them to iPhone, so I can watch them during the morning commute. When the show begins, iMac's screen wakes up. When the export to iTunes begins, the screen wakes up. I tried few utilities where the brightness dims 100%, but it's not the same as turning it completely off.
Has anyone found a solution where you can turn off the display completely? Since my iMac is in my bedroom, this is a huge problem for me. I miss my Mac Mini....
My Intel-based imac keeps hanging my programs like Word and Excel, Chrome, Firefox, etc. I force quit, then try to re-start, but get spinning wheel. I try to shut down and desktop clears, but won't actually shut down unless I push the button. It's doing it every day, almost every time I go to use any of my core programs.
I got a RAM upgrade, and an OWC Mercury Elite Pro HD to take the back ups.
Oh - I also record a moderate amount of music in Garage Band - could this be clogging up everything?
Whenever I need to shut my computer down from the apple menu it hangs. It does the same thing whenever I try to restart it. It's annoying. The only way I can get results is to physically shut it off.

I have a new imac 3.4ghz - i7 with 16gbs ram that won't shut down unless I hold in the power button. I checked the Console logs but that did not give me any indication of what might be hanging it up. I also, have a Macbook Pro running 10.6.8 and it has no trouble powering down. Â

View 3 Replies View RelatedI have an Intel Imac G5 2.66 gHz 2 core duo running 10.6.3. I am unable to get it shut down or sleep. Choosing either results in the display blacking out, the fans run for about 1 second and then everything come back on as if nothing has happened. I've reset the Pram and Vram, disconnected all USB and Firewire devices, tried it with and without file sharing and Airport operating. A 'hard' shutdown with the power button works fine. I have checked for any firmware updates but mine is fine. This happened once before and clearing out some files from deleted apps cured the problem but it's back now.
View 4 Replies View RelatedI often have an issue where my iMac won't shut down, restart or logout users. Basically, when I click Shut Down or Restart, the desktop icons disappear as if the computer's getting ready to shut down (the desktop wallpaper remains) and it just sits there and won't shut down. I have to hold down the power button on the back of the computer in order to get the computer to shut off. This often happens when I try to logout a user. I'd say this happens about 2/3 to 3/4 of my attempts to shut down or logout a user.
View 6 Replies View RelatedI downloaded Mac OS X 10.5.7 from the Apple website rather than using Software Update only to save time. I used Software Update to get 10.5.7 on my MacBook Pro and it took 35 minutes to download the package. Using the Apple website for my iMac, the download took about 15 minutes.
I then began the installation of 10.5.7 on the iMac. Everything went fine until it was time to restart. The computer froze on restart. I had to hold down the power button to turn off the iMac. Then I started it up and it began to load for quite a while (normal after an update). Then I logged in and went to "About This Mac" and it read that I had Mac OS X 10.5.7.
Obviously, this is an unorthodox way of updating. But am I safe with this method? Was it just a minor glitch?
So I've done all I can find on the internet on helping my broken computer. It used to have the noisy fan issue and then it would shut off. Now after being off for 12 hours, it may shut off in 2 minutes, maybe in 30. I have reset the SMU by unplugging for 10 seconds and then plugging in while simultaneously holding the power button, then turning it on. Ive also reset the PRAM, but it still seems to shut off. Is it a bad power supply? I dont ever hear the fans blowing hard anymore.
If anyone has basic things to do, I'm all ears. I know last step is probably just reinstall OSX.
I'm on 10.4 right now.
My 24in iMac is waking from sleep after about 5 seconds every time, as well as restarting itself after I shut down. This problem started early yesterday evening, and so I did the usual: resetting the SMC/PRAM/NVRAM with no luck. I checked console for messages and found lots of references to imagneto_user_agent (I'd installed iMagneto shortly before and then deleted it as it didn't seem to be working properly). With some help from another user I managed to delete all the hidden/locked folders and files connected with this app using a combination of Trash It and fiddling in Terminal.

I recently bought an iMac and I have noticed within the past week that I have had to force the mail program to shut down. Otherwise if I don't force the mail program to shut down the OS will not let me put the iMac to sleep or to shut down.
View 2 Replies View Relatedtonight I started having trouble with my intel iMac (running OSX 10.4.11). I'm having issues with two things (bolded for those skimming):
Out of seemingly nowhere, my iSight light turned on and now wont turn off. The only program I had open at the time was Firefox. When I try to open up PhotoBooth it says this:
There's nothing listed under USB High-Speed Bus in the system profiler either.
I've tried logging out of my user account, restarting, shutting down, unplugging and holding the back button for 5 seconds ...none of that worked. I tried resetting my Mac's PRAM and NVRAM. That didn't work either, and that's where a second problem appeared: when I try to shut my computer off, it freezes. I have to shut it off by holding the back button.
Is repairing the permissions and/or disk worth a shot? Or should I just take it straight into the Apple store? I hope it's not a hardware issue because I just recently had a new hard-drive installed after it broke down on December 15.
I was just in my room minding my own business and I heard my iMac "shut down" but nothing happened, and I'm still able to use it like normal as I type this message.It seemed to quiet down my fans though, they are still running but much quieter so I guess in a way its a good thing.I'm just curious as to what happened here.

It seems to happen when both users have been signed on. I log out on both accounts, shutdown (or restart) and it still hangs up. If I use just one account, it's hit and miss. No applications are hanging in the force quit menu.

My iMac runs perfectly fine; more or less as it did when it was new. In OS X, when I shut down the computer, the fan runs at full speed indefinitely, unless I unplug it or boot back up. When running, the fan is perfectly normal (increases speed a bit when doing something taxing). I've never heard it at full speed before until this started happening. After following the SMC reset procedure with no luck (I'd like to add that the SMC reset only says it relates to fan problems when the computer is ON), I searched a bit and noticed there are one or two cases where a problem like mine was believed to be a motherboard issue, and therefore a costly fix.Â
However, here's the fun part. When booted into Windows 8.1, shutting down the iMac does not cause this issue to occur. It stays silent, as it should, even if I disconnect then reconnect the power. This leads me to believe it's unlikely to be a motherboard issue. However I've wiped, restored, and reinstalled fresh copies of Mountain Lion, Mavericks, and Windows 8.1, and the result is still the same: if I don't want to have to unplug it from the wall, then I have to use Windows to shut it down.Â
So then, my questions are these:
-What is the difference between shutting down from OS X and shutting down from Windows?
-Is an operating system allowed/able to touch BIOS settings?
-Is it possible to still be a hardware problem, given this difference?Â
My default OS is OS X, and it makes no difference if I change that to Windows. I also did a PRAM reset, even though that has nothing to do with fans...

My mac is 6 months old has the latest OS. When I leave it playing music either in Itunes or on u tube. It shuts down to login after 15 minutes. If I am using it it does not. I have disabled all energy saving options and all "never shut down" options selected. But everytime I leave it religiously shuts down after 15 minutes.

I used to have a wireless Logitech mouse that drained batteries if you didn't turn it off manually every time you finished using it. So I'm wondering about the Magic Mouse...
1. Does the Magic Mouse automatically shut off when the iMac goes to sleep or is turned off?
2. If I leave the Magic Mouse on (while the computer is off) will it drain the batteries?
3. What do you recommend is best for the batteries and mouse? Should I turn it off every time I go out for the day?
I have an older e-mac that I use and the display suddenly became distorted and stretched. I can't see all of the words in finder or even the apple icon to shut down the computer...it has stretched far off of the display.I tried the display settings in system preferences and tried to adjust settings in geometry I can adjust the height but not the width.
