When ever I turn off my iMac (AL mid-2007 running 10.5) it seems like it hangs during shutdown. It takes about 60 seconds to shutdown and after about 30 seconds it starts to show. It looks like this, except it still shows my wallpaper... (This is just an image I found on the web). I am not sure why it is taking so long to shutdown lately... I don't remember it taking nearly this long in the past. Here is a photo of everything that is running during shutdown and it still does it. (I usually try to close out of apps before shutting down).

I have a MacBook Pro 2.16 C2D that I just updated with Leopard. I noticed that occasionally the computer will hang when I attempt a shutdown. I didn't have this problem with Tiger so I assume it's a bug in Leopard. When I try a normal shutdown all I see is my desktop wallpaper and that little circular animated icon. I have to hold in the power button to force a shutdown.

When I had just installed the Intel X25M (80 gb G2) shutdowns took merely 2 seconds. Now, after the dock minimizes adn hte icons disappear, the computer just hangs for 10-15 seconds, turns into a blue screen and hangs for maybe 10 seconds more before actually shutting down (black screen, everything off).
Does anyone know what is wrong? The drive is only 2-3 months old, and I still have 40 Gb free.
I was thinking it is some program that is running in the background that is having trouble quitting.

I have a iMac(20") for about a year now and its ran great up untill now. It is hanging on boot. Sometimes its the white screen with apple logo and spinning gear, other times the screen goes blue and i can see it load a mouse cursor for about 2 seconds, then the screen goes through a few shades of blue and the spinning gear re-apears with no apple logo. The computer then loops. I tried to boot to safe mode, but as i have the sound off i am not sure i am holding the shift key at teh proper moment. If anyone has any advice, please, please let me know. my mac reinstall cd is about 8hrs drive from where i am, and i do not know if mac issues replacement cd's.

I was working on my iMac (last year's model) today and the finder hung up (beach ball spinning). I force quit the finder, but it then refused to relaunch (although I could use other programs as before). I then tried to restart the computer but couldn't, and had to force the power off by holding the power button for a few seconds. Now when the computer starts up, it gets to the point where the "loading wheel" (with external spokes) starts turning, but then this "wheel" freezes. I put in my TechTool Pro 5 disc to start it up from that, but the same thing happens (yes, I have been holding down "C" when it starts to make sure that it uses it as a start-up disc). I am at a total loss, and live far from any computer repair store.

I've got a 1st generation iMac G5 (I think, from 2004) running 10.4.x that has become 'the family' computer since I upgraded this past winter. I haven't been keeping up with updates and decided about 3 weeks ago to finally go through and update everything; had been at least 4 mo.s since the last update and udates included Java Script, iTunes and a Security Update. I started downloading the updates then quit Safari (which had previously been running) walked away to do other things around the house (since it would take a while) and when I came back I had an error message that the logout (to restart - which was required for the Security Update) had timed out because Safari would/could not quit. I clicked OK, force quit Safari and shut down the computer (since no one was going to be using it for the rest of the day and a restart was required anyway).
Came back the next day to startup the computer and it just hung at the blue screen with the mouse arrow. Assuming there was something wrong with the update that was just installed OR the startup disk I reset the PRAM/NVRAM: no change. Tried starting in safe mode: wouldn't (and still won't) move past the blue screen with spinning gear. Tried to boot from install disc to repair the HDD with Disk Utility: Couldn't repair the disk volume (Invalid leaf record count: should be 13 was 1203). Tried single user fsck: scanned twice and reported volume repaired, went to restart - still hangs, tried to boot in safe mode again - still hangs at blue screen with spinning gear. And that's where I'm at now. Anyone got any good other ideas out there? I've searched a lot and haven't found anything I haven't tried. I'm guessing the installed update(s) never completely installed and screwed something up on the startup disk. But I can't access ANYTHING to figure out if that was the problem. I would really like to keep this computer for the kids but don't want to spend any money on it if I can avoid it.

I'm troubleshooting an iMac G5, Tiger 10.4.11. The first problem was a -50 error, which prompted me to repair via Disk Utility (which failed), and finally to replace the catalog via DiskWarrior (which succeeded). After another boot crash, and two instances of reinstalling the system, these are the results:
1. I can boot from system CD.
2. I cannot see the internal HD in Disk Utility on the CD.
3. I can reinstall the system successfully using Archive and Install.
4. Immediately after reinstalling system, computer boots up normally.
5. Computer will eventually crash with a spinning beach ball.
6. After a forced restart, the startup stalls at the grey apple logo.

My iMac will chime, then hang on the grey apple screen with the spinning gear. After a few minutes, it shuts off. Tried resetting Pram and all... Did not work. I troubleshooted using another website, and found it to be an I/O Error. The issue is I need to reinstall the OS, however, when I boot the install CD it hangs the minute I click the mouse or keyboard.

I'm running Leopard 10.5.8 on an iMac and continuously have problems booting the machine. The boot process occasionally hangs at the gray screen, but more often it hangs at the blue screen. Sometimes it makes it to the login screen where the cursor occasionally freezes. Whenever these problems occur I have to shut down by holding down the start button, then restart again. Usually the second boot is successful. This booting problem occurs frequently, even after running Disk Warrior and repairing permissions. I don't think this is normal behavior. Has anyone else had such problems? Is there anything I can do to correct this behavior, or is this something that needs to be fixed by Apple?

It's been having trouble shutting down when it's gone unused. Then it won't turn on unless I turn the surge protector off and back on. (I thought it was tied to my backup drive being on, but now I just turn it on when I need it) Even then it doesn't start up automatically, I have to push it a few times. Just now when I held down the start up button it made a loud whooshing sound, started up, maintained the sound for awhile and then normal but I still hear it running louder than usual. I dread it may not start up again one of these times. Side issue, maybe unrelated but firefox is driving me crazy with proxy issues, aol mail issues, and just now I couldn't post in this forum it was "forbidden" when I hit submit. so I used Safari instead and found my post was actually posted.

New owner of iMac 24" 2.8 since last March. Just recently I have noticed that when I take off for a few days, I shutdown the iMac and when I return home a few days later and hit the power button the iMac is already on in sleep mode. The only change I have made recently was to add Time Machine on a Guardian Maximus 1TB raid drive, but I usually power off that drive when I leave. I've checked and searched here and in the Apple discussions with no luck. Does anyone have any idea what might be happening?

After a full shutting down the computer we needed to get back on, so on restart it came up to the usual 2 user options, mine and guest.
After selecting mine and entering my password the little Ferris wheel spins as usual but then the coloured pin wheel come up and spins for about 2seconds. The screen then flashes white and it goes back to selecting between the 2 users.
I did a Command R restart and went in to Utilities and changed my password (although I was entering it in correctly before) and no change.
I am running the latest updated version of Mavericks and have unplugged all peripheral hardware from the computer, followed by a restart and no change.
I've even left the computer shut down for 2 days and on our return still the same.

Glass over hangs on left and is in a bit on right side on my new 27" i5. So is this normal? Also I think my screen is a little yellow bottom right.

i got a white screen when i booted up last night, so i saw it as an opportunity to upgrade rather than trying to fix it. I popped in a fresh copy of snow leopard, it made my white screen boot up. before installing, i opened disk utility and erased my hard drive, and it automatically made a single partition, titled "untitled" and mounted it. i installed to "untitled" and turned install log, and the progress bar is empty. time remaining: about 30 minutes log: checking catalog file is the last line, and it's been there for over 1 hour. i restarted and now it says "volume headers need minor repairs" "repairing volume" and hangs there now.

I am having some problems with this computer. Suddenly shuts itself off I have had trouble turning it back on. At times I try unplugging the power cord (both ways), and any peripherals (USB, Firewire). Sometimes it works and other times no. I pretty much have to play around with it - but right now I can't turn it back on! In case some are wondering, it is running Tiger, 1 GB of RAM, and I keep it running pretty much around the clock.

It's a G5 20" 2.0ghz machine and is 15 months old approx. He was running something or other, nothing very taxing, when the computer unexpectedly shut down. He restarted it and within a few mins it shutdown again. He restarted it again and used it fine for a couple of hours, shut it down and went to bed. Came to it the next day and nothing. No noise, no lights, nothing. He dropped it off at a local authorised dealer and they thought it was either going to be the power supply (�100 to fix) or the main board (�600 to fix). Sure enough he got the call and it's the logic board thats gone. He doesnt have applecare unfortunately but decided to try his luck and contact apple anyway. Needless to say, they weren't in the least interested and told him he'd either have to foot the bill or toss the machine in the bin. �600 to fix one of these is appauling and more than the machine itself is worth but the options are limited. Has anyone else experienced anything like this and if so are there places to get the machines fixed cheaper? I know this goes to show that it's a good idea to stump up the extra cash initially for applecare but �1200 (the price when new) seems pretty bad for 15 months computing and has really put me off recommending iMacs to anyone else. The days when I can construct my own computer with my own components and run OS X on it, and repair it myself cant come soon enough if this is how it's going.

I was watching a movie on my iMac and this box popped up telling me to hard shutdown and restart my computer. Now I can't get it to turn on. When I press power it makes the start noise but the screen stays white. The apple doesn't pop up and it won't load. Trying to put in disks that came with my computer don't seem to work either.

I've been looking around on a few forums, and I've tried to reset PMU, hold the programmer key, take out battery let it be, external screen,... None of it worked for me. I have tried to install Os X Jaguar without upgrading firmware, so it told me that it needed to upgrade. But I can't do that since it doesn't boot anymore. I tried disconnecting the harddrive and boot it without it, it still turns off. [URl]

I create a wi-fi network to use computer to computer. When I shutdown the IMAC the network disappears. When I go to ctreate again all the info is there for the network I created, but the network does not appear. If I name it again I can use it but then again it disappears when IMAC is shutdown. Is there anyway to save it? I have ude the apply button and reclosed the lock, but same results.

I updated my iMac with 10.7.4 and now when I have been working on it it won't shut down. I thought it was only when I was using Photoshop and contacted Apple who told me to reinstall Photoshop but it made no difference but now it happens with all programs I am using.

My system has randomly shut down twice now in the last two days. Dual G5 2.3. I checked the console log, which I know very little about, and it said this:
localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122
Two questions-
what's the -122 code mean?
Do you think resetting the PMU would be the solution to this?
