My iMac freezes up, Snow Leopard Intel-based dual-core

Hello everyone,
My first posting here, unfortunately not a happy one. I have a 2006 iMac, with a built in camera, 320GB 2GB RAM and Snow Leopard installed. No windows bootcamp installed.
For the last few weeks I've been noticing the computer getting slower and slower. Last night I ran the Disk utility and found there were some issues with the hard disk. I next ran the disk utility from the Installation DVD and fixed the errors, and subsequently ran disk utility again only to get a notification back there were no further issuese with the hard drive.
The new problem now, is the computer takes over five minutes to reboot (stays on the white screen after coming on all this time) and once up is slowly becomes completely unresponsive. The screen has horizontal lines across it and after a few minutes it is as if nothing is happening on it. I can still move the mouse, but clicking the mouse does nothing, and even after leaving it like that overnight I was unable to get any response from the computer.
I was hoping some of you might be able to help me out here.
Thanks in advance!

Ok, so it has been a few weeks since this fix. Problem is, the problem keeps resurfacing every so often. And by every so often I mean every two-three days.
Fine, not a big bother. Until two days ago, where nothing I do is helping anymore. The computer starts up, and within seconds everything is frozen. I have maybe a 2 minute window in which I can do something, and then the computer starts slowing down. Another ten minutes, in which I can maybe (if I am pushing it) get one email out, and then the screen is frozen. Nothing I do works.
Any suggestions?

2007 iMac freezes up, rainbow wheel appears when this happens. I know the computer is starting to get old but I can't afford a new one at this time and would love to continue using my Mac, but it's frustrating. Would a fresh install or OS upgrade resolve?

My circa 2007 iMac freezes up, and rainbow wheel appears when this happens. I know the computer is starting to get old but I can't afford a new one at this time and would love to continue using my Mac, but it's frustrating. Most of the time I ONLY have 1 thing open at a time, and keep my tabs down to a minimum. I bought this to do film editing on but with it acting like this I cannot do that. I know I need a ram upgrade (currently running 2 gb) and my OS is old, 10.5.8, but I think even with it being a bit outdated it should run better than this. Would a fresh install or OS upgrade resolve this? Or any other suggestions to keep this clunker chugging along for a little while longer?

How full is the hard drive?
Do you run any virus software or hard drive "cleaner" software like MacKeeper?
If your model is from 2007 you can install up to 6 GBs of RAM.
2 GBs is the barest of minimum RAM for OS X to run on.
Especially if doing video work. You simply do not have sufficient RAM.
Also OS X 10.5.8 Leopard support ended around 2009.
You could update to OS X 10.6 Snow Leopard, at least.
It is available on disc from the Apple store for U.S. $19.99.
I Would seriously upgrade your iMac's RAM to the max. 6 GBs before doing this.
Reliable Mac RAM can be purchase from online Mac RAM source Crucial memory or OWC ( also known as macsales).

Imac freezes in Leopard

My iMac freezes and locks-up when I do certain things.
a) Go into the Video/Audio pane on ichat prefs
b) when I'm scrolling through image sin preview
c) when using time machine sometimes
d) once or twice when switching to full screen in Parallels
e) in frontrow once
Any ideas?

You should try reinstalling Leopard Make sure to to a full clean install, also check your ram if you have less then 2gb turn off some features of the OS ( or get more ) if you think you have more ram than what is showing up then you have a bad ram chip and that would cause allot of what you are talking about to happen.

Until I installed the SMC FanControl application my screen would "break up" into strange patterns and then would eventually freeze. Please help.

If you are trying to upgrade using a gray-faced OS X disk from another system, that won't work, as those disks are locked to the system types they are delivered with. You'll need to drop the $29 on a retail copy of Snow Leopard, which is available from the Apple online store. Note Snow Leopard requires 1GB minimum, and you may want at least 2GB for better performance.

IMac crashing and freezing continuously

Since 2 weeks, after years of 0 problems, my iMac is continuously freezing or crashing when I use Apple software (Mail, Software Update, Garageband).
I've installed Kaspersky and even reinstalled Mac OS Lion, same problem.
It goes away temportarily when I restart cleaning the PRAM. or turning off the extensions.

Boot from your installer dvd and use Disk Utility to repair/verify your drives.
Remove Kaspersky.

No you won't, iMovie 6 will continue to work, and having two or more versions of iMovie should not be a problem.

IMac freezing but I can move cursor and music continues playing

Hi all, I am having trouble with my iMac freezing. It has done it three times in the last five days. Today, I had Safari and Pages open and was listening to iTunes in the background. I left the room for a couple of minutes and came back, the music was still playing, the clock was frozen, I could move my mouse but could not click on anything.
Yesterday, the same thing happened, I ran disk utility and cleared off some old third party apps that I wasn't using. I noticed improved speed in my browsing and the loading of apps and thought the problem was solved. Now that it has hapened today I am perplexed. Activity monitor doesn't show anythig out of whack. I saved some info from the activity log:

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

My Imac freezes 5 x a day at least... please help!!!

Hello,
I'm pulling my hair out because I use my Imac for all my work. Everyday I hold down the reset button *at least 5 times* because the Imac freezes.
-Updated all software
-Repaired disk permissions
-Bought another gig of ram
-Won't completely verify disk, says: *Error: underlying task reported failure on exit, 1HFS volume needs repair*
- Won't allow me to repair disk
What I don't get is that when things freeze, I hit force quit and they don't quit?!! I mean the little black arrow remains underneath the icon. Then I hit "restart" in menu and it won't restart, it just freezes. I thought that was the whole point of force quitting?
So after the screen just freezes blue with the black spinning icon, I have to hold the reset button. Sometimes I don't even get that far, I have to do it on the desktop.
Any help would be greatly appreciated!!! The guy at the computer store said good luck when I asked if anyone in town fixed Macs, lol!

+Won't allow me to repair disk+
It is a different procedure from repairing permissions, which was not the problem, but which you did correctly perform. You can only repair disk using Disk Utility on another volume, not from the same volume, and the other volume must be the same version of OS X.
If you are still using Tiger 10.4.11, not Leopard or SL, boot from your grey-labeled Install Disc and after the first screen there will be a menu bar at the top that includes a Utilities menu from which you can choose Disk Utility. You will be able to try the Repair Disk button, and you should run it completely through at least twice to see if you can get it repaired.
Then quit and restart, don't continue further into the install process. Eject the Install Disc.
If your OS X is now Leopard or SL, make sure that you use the same disc that installed your current OS X.

IMac Freezing - No video glitch, but unresponsive

Good morning all,
In the past week or so, I've started to have problems with my iMac freezing. This has occurred while using iChat, playing World of Warcraft and while using Safari (not all at once).
In short, the video display seems to freeze. I can still hear audio (ie. the other person on iChat speaking), but everything else in non-responsive. The keyboard does not respond and I cannot ALT-Tab or open any other programs. My only recourse is to manually turn off the computer and try again.
It's usually a guaranteed failure when opening up Warcraft. About 4 seconds after the program has opened, the computer freezes.
I've searched the forums and have come across several threads that involve some sort of graphical glitch, from which I do not suffer. That being said, I thought a new thread might be appropriate.
Any advice would be greatly appreciated.
Thank you,

My iMac has been repeatedly freezing when I am working in Final Cut Express. It plays the sound but freezes the video. It has been a horrible experience to try to edit 'blind'!
I have vacuumed the air vents, installed smcFan Control (great to manual adjust fan speeds on all 3 internal fans), re-installed Snow Leopard & gone through copious hours as all the software updates each time I've re-installed, and I run the disc doctor program. It started happening around the time Steve Jobs said Apple would no longer use Flash. I thought it a Flash issue since it only has to do with the playback of video. Today I discovered that clips I downloaded yesterday were also freezing in my desktop Picasa. Meaning it's not Final Cut, or Picasa, and unlikely my video card as all videos streamed from the NET (on YouTube, etc) play fine, and in fact my videos that freeze on my iMac when uploaded to YouTube or Facebook play fine.
I am enormously and thoroughly frustrated, as you can imagine. I had 15 clips from the G20 Protest March yesterday and was not able to make an adequate video to upload out of them because the video keeps freezing, and losing synch with the audio - and every time you try to play it, it freezes in a different spot!!
Horrendous problem.
Today, then, following advice in this thread, I will try re-installing back an update or so on OSX - I'm using 10.6.4, and perhaps need to go backwards?
This is an awful problem and I am surprised Apple hasn't addressed it. Perhaps it only relates to computers a few years old?
A usually very happy iMac user who is very disgruntled these days...

My 30inch iMac freezes up after the screensave has been running for a few minutes. This happens about every other day. I leave my system running all the time. nothing will unfreeze things so I have to do a hard button reset. I am running all the latest system updates etc.

Reinstall Safari 5.0.6 for Leopard
Then restart your Mac, try Safari.
If it crashes again, third party plugins could still be at fault even though they do not show up in the report.
Follow the troubleshooting help here > Safari: Unsupported third-party add-ons may cause Safari to unexpectedly quit or have performance issues

IMac Freezes in everything other than Windows 7

--------------------------------------------------------------------------------
My iMac was running Snow Leopard and Windows 7 via Boot Camp successfully with no issues until yesterday. The iMac froze in Snow Leopard and I had to manually reboot by holding down power button.
Since then OS X won't run, Windows is still OK. If I select OS X the iMac freezes on the grey screen. I've tried safe mode and still no joy as it freezes on the grey screen as well.
If I place my OS X 10.6 install disk in the dvd drive it reads the disk, stays on the grey screen and after 2 minutes I then get the Kernel panic screen to reboot. Tried on a 10.5 Install disk in case disk was the problem but it does the same thing (windows install disk works fine, so DVD player OK).
Have also reset PROM and NVRAM. Rebooted machine using cmd S into Linux to check disk and it found no issues.
Anyone got any other ideas. I have a full time machine backup so trashing the hard disk if I could would be OK.

Just managed to get the cmd v command working but only with placing the OS X install disk in. It shows a long list of directories and folders that it tries to find the number of files but it can't count due to missing folder.
I'm wondering if Windows 7 has done something. I would love to get this machine in a position so I can wipe the whole disk as if new and reinstall OS X but as I mentioned before I get the Kernal panic if I place an OS X install disk in

My iMac freezes when using Firefox

My iMac freezes when using Firefox. We have to restart our computer.

TutorDaddy, if this Mac is still covered by the initial warranty or under AppleCare, take it in and have it looked at. As the old label used to say, there truly are "no user serviceable parts inside." Kernel panics very usually indicate failing hardware.
I have an older iBook G4 that started developing kernel panics and like you, despite reinstalling the OS from a freshly formatted volume, they kept continuing. I looked at the crash log and saw that in each instance of panic, the last bit of code to be accessed had something to do with AirPort. Knowing that the AirPort software was at then current levels, I surmised the problem to be a bad AirPort networking card which, on that particular model of the iBook, was a very small module attached directly to the logic board. Since the computer was out of AppleCare, I broke the machine down myself (I didn't realize that there could be so many barely visible screws in one machine) and removed the offending piece of hardware. My iBook lives but without WiFi, it now sits as a more or less desktop machine needing an ethernet connection to stay connected to a network.
I do not suggest you break into your iMac. First of all, I'm guessing one would need to be able to pull off the glass and have the necessary glue to reattach it, which is not really available to us consumers. If you're feeling adventurous enough to read the crash logs from each panic, you might be able to surmise the hardware component (or badly written application or library; it can happen) that's causing the panic. If it's a software issue, remove the offending software app and see if the panics return. If it's a hardware issue, it's best to let a competent service tech qualified on Apple hardware to handle it.

After browsing through related problems in the discussions, I saw this link to a third-party web site being handed out. Perhaps you'll find it useful: http://www.thexlab.com/faqs/kernelpanics.html

IMac Freezes Periodically During Screen Saver Only

I own a late-2006 Intel-based iMac. Over the last few months, I've noticed that the iMac freezes when the screen saver is running. This doesn't happen all the time, and it doesn't matter what screen saver I use. (None of the screen savers is a third-party.) The iMac doesn't freeze at any other time.
Any ideas?

P.S. I'm running Snow Leopard right now, and it happens even with Snow Leopard, just as it did with plain ol' Leopard.

Your iMac has a dedicated Graphic's chip (GPU), while some of the Late 2006 17" iMacs had a GMA 950 graphics processor with 64MB of DDR2 SDRAM that shared with the main memory. To check which Graphic's chip you have go to: Apple > About This Mac > More Info and in the Hardware section select Graphics/Display.
If you would like to monitor the temperature of your GPU, CPU, HD and Memory check out the iStat Pro widget > http://www.islayer.com/apps/istatpro/
The main reason I suspect the lack of RAM over an overheating GPU is because you only reported a problem with the Screen Saver and not with other intense graphic's like movies, videos or games.
Please let us know how you make out with the RAM upgrade.
