My iMac freezes
My iMac is starting to lock up from time to time. Doesn't appear to be dependent upon what or how many applications are open.

Brand new iMac freezes constantly! Updates aren't helping!
Hello everyone,
This past Sunday I bought a brand new iMac intel Core 2 Duo with a 250 GB HDD and 1 GB of RAM. At home I set it up with my SAMSUNG 1080p 22" monitor, Apple bluetooth Keyboard and mightymouse, and a Western Digital 350 GB HDD hooked up via USB. I was excited to finally jump on the intel-based Mac bandwagon, as well as experience dual monitors for the first time.
That was Sunday. Tuesday evening I was watching "Rome" on itunes on my Samsung monitor while surfing the web with Omniweb on the iMac monitor. All of sudden, everything locked up. I was able to move my cursor, but nothing responeded to my clicking. I hard booted the system and loaded everything I had going again, and sure enough, it locked up a few moments later. I ran system update, updated everything, then restarted. Time went by and although not immediatly, later that night it froze up on me again.
Fast forward to last nite, and the freezing reached and all time high. 5 times. Each time was when I had a browser open in my iMac window and I had Quicktime playing in my Samsung monitor. I was watching a sports program, with the player fit to the screen.
I have read many posts about intel iMacs freezing late last year, but there was a firmware update that evidently fixed that. I have this update installed, and I have had no luck. I have even contacted Apple Care via phone where I got instructed to unplug everything, plug it back in, start in safe mode, and delete cache. That didn't help me out at all. Am I right insuspecting I have a faulty Video card? I just ordered 4GB of RAM, could this be a RAM issue?When diagnostics are run on a freezing computer and nothing shows, I'll put the program into a testing loop because this means one of two things: the issue is heat related so running the diagnostics several more times will bring on the heat so that the issue shows up or the installed RAM is marginal, just flaky enough to show up now and again but not so far off that a run through of the memory test catches it on the first run.
As I said in my original post, memory is always a suspect in a freezing or kernel panicking computer. And it does tend to top my list. But from what you describe I'm not quite willing to say, "Why don't you just wait until the RAM upgrade arrives?" -
Imac freezes during start-up. Seems to be caused by Airport issue.
My Imac freezes during startup. I have tried starting it in safe mode without any luck. After the initial start sequence when it gets to this point: Airport linkup en1, the computer starts writing the same line endlessly: com.apple.launch [1] (com.apple.mDNSRsponder [2710]): posix_spawnp (“/usr/sbin/mDNSResponder”,...): No such file or directory
I am not a technician and new to Macs too. I have tried almost everything in the supportfile about freeze issues. I am not able to start the Mac in safe mode. I have repaired the disk. I have tried reinstalling the software, but this fails too.
Did a couple of changes on the timecapsule before it happened (creating a network and new security settings and backup settings) and installed Photoshop Elements 9 and did a lot of file restructuring. Left the computer open and came back to a blue screen. Since then I have been unable to start.
My macbook works fine with the changes. I am stuck - what to try now?
I need my files and they are luckily on the timecapsule, but i am not able to open the imac-bundle file on the macbook, why?
Thanks for helping.did a lot of file restructuring.
In Finder>Go>enter /usr/sbin do you see mDNSResponder listed there?
Try Repairing Permissions for the Volume in Disk Utility (Note: may take a long time in 10.5.8) -
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). -

I have disabled Safari Extensions, and didn't succeed to remove Avira's kext file, but as I said, I have experienced this freezes before I had Avira.
I don't think that is the problem.
Can anyone help me and recommend what else should I do? This thing is quite annoying. My iMac is my workplace and constant freezes are frustrating.
Thanks in advance -
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?

24" iMac freezing occasionally/Please Help
24" iMac freezing occasionally without allowing force quit. Sometimes when I attempt to restart it, when the computer comes back on it will freeze on a gray screen with a folder in the middle with a question mark on it. If I unplug all peripherals and the iMac power cord and let it sit for a while, it starts working again Sometimes I might get 4 days of use before it happens again. Then sometimes it might happen 2 or 3 times in a day. I've always heard the gray screen with foler with question mark was the mark of death for the hard drive. If this information is true, how am I able to get it to work occasionally with no porblems?
Thanks,
34firefighterI found out what was happening... I was running screen dimming software called 'Shades' which was messing up the colour profile allocation. I stopped this software running and I was able to recalibrate! I'm so pleased as I thought there was something wrong with my graphics card!

IMac freezing - using 10.5 with newest 24" Intel
I've read a lot of posts about iMacs freezing and they seem to be mainly with the older gen's of them.
In my case, my 24" Intel iMac freezes and the mouse will not move, the force quit won't work as the keyboard doesn't respond, nothing works, basically I just have a screen and nothing happens.
I can only force shut down and restart the computer. The same problem has happened at least once to my wife and she did the same thing except put the computer to sleep with the power button and restarted with the power button and she got a message that the mouse wasn't synced up with the bluetooth.
Can this problem have anything related to using the wireless mouse and keyboard? I also read something about issues with freezing and that it was addressed with the newest software update.
thanks for the helpHello,
*"restarted with the power button and she got a message that the mouse wasn't synced up with the bluetooth"*
To set up a Bluetooth device to work with your computer:
Choose Apple menu > System Preferences and then click Bluetooth.
Click Add +
Choose the type of device you want to set up and follow the onscreen instructions and when you are finished restart the iMac.
If the iMac still freezes...
Try resetting the SMC, instructions here. http://support.apple.com/kb/HT1543
Try resetting the PRAM and NVRAM, instructions here. http://support.apple.com/kb/HT1379
Check the hard disk. Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
*"Can this problem have anything related to using the wireless mouse and keyboard? I also read something about issues with freezing and that it was addressed with the newest software update"*
The most recent software update was for iTunes, so I'm not sure which software update you are referring to.

Keep getting message - You need to restart your computer - iMac freezes
My iMac freezes without notice, a dark screen comes over the monitor and the message "you need to restart your computer" appears.
This happens randomly and I have no idea what causes this. I thought perhaps it was just a loose power cord, as the cord does seem quite loose.
However, it happens after the machine has been running for some time. Before I have a chance to save my work, the computer tells me it has to shut down. It's not a consistent thing, so it's hard to know if it's the cord or not.
This also happened half way through watching a DVD. Nothing was touched or moved, so it wouldn't appear that this is being caused by a loose cord.
Can anyone shed some light on this problem? (I'm running Tiger on this machine with 700+ megs of RAM plus am using a Mac keyboard. Airport is installed but not in use.Hi there,
I would first make sure your Mac is or isn't on any list contained here: http://www.apple.com/support/exchange_repair/imac.html - you may in fact have a faulty power supply which is covered by repair extension through Apple.
Here's a brief explanation on a Kernel Panic: http://docs.info.apple.com/article.html?artnum=106227

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.

My iMac freezes up after the screensaver runs for a few minutes
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 -
The only program I installed is Ableton Live Lite Akai Edition, which I need. I have one free app downloaded, Sketchbook Pro Express, which I need. My iMac freezes a lot, sometimes when I start it up, sometimes when I am working stuff, sometimes when I am on the internet. I have turned it off and unplugged it multiple times. I've only had my iMac for around 4 months, and I bought it brand new. What do I need to do?
Hello, see how many of these you can answer...
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab, are there a lot of Pageouts? -

Ever since installing Lion my Imac freezes when in sleep mode. Has anyone had the same problem and been able to fix it
Yes, I have the same problem sometimes, along with numerous others. It appears to be a bug with Bluetooth failing to wake up.
The 'fix' that works for me and others on here, according to responses on the forum, is to go to System Preferences>Energy Saver and set 'Computer sleep' to 'never'. For me, this provides a totally reliable solution that I can live with until Apple come up with a fix (hopefully). -
My iMac freezes up shortly after startup.
My iMac freezes up shortly after startup. I can't move the mouse or use the keyboard. I have to manually shut down several times before it would work.
Hi patrickbryant,
Thank you for participating in the Apple Support Communities.
If your iMac is becoming unresponsive when you start up, I recommend trying to boot into Safe Mode as well as using Disk Utility to verify your hard disk. You can find these steps outlined at this link:
