    I just purchased a 24" iMac yesterday and it is also freezing up every time I use Photo Booth. I have OS 10.5 with updates. Nice machine but I thought the Apple OS would be rock solid with unix underneath (I am a windows user, bought the iMac for my wife). I am very disillusioned with the iMac, OS 10.5 mostly just hype, not born out in performance.

    Again, I think is not Leopard, but the iMac the problem. Leopard is just fine, I also installed on an "old" imac G4 (1ghz) and it runs good.

    Fair enough. Be aware then (and this is for all 'switchers' out there) that this is HIGHLY unusual for Apple. Most times if there is a problem it's s/w and easily and quickly fixed. My 7 year old 1GHz G4 is running 10.5 and I have never had a problem with it except for a couple of cooked hard drives. That is what you can expect from Apple once this is fixed.

    Well if it's that bad, just return it and stop complaining... this thread is not about ******** at apple, but about the problems you're experiencing with the iMac and the freezing issue...

    the OS is rock solid, it performs very well (user have said that vista runs faster on the mac) Just because you got one of the rotten apple doesn't mean they are all like that..Mine is cured and works very well. You still have 12 days to either return it and get your money back or get another one... Your chances of getting 2 bad ones in a row are slim, but possible..

    After applying 1.3 update under leopard and doing a PRAM flash, my mac stopped freezing on all the normal ways in getting it to crash (visualizer full screen itunes, dock left-right, arabeque, etc). HOWEVER it just froze again, spinning ball, itunes still playing music in the background. The 1.3 update did improve the freezing, but has not stopped it. Not sure if i should take it in for repair, or wait for another update as apple released a statement on computerworld saying they are working on it again.

    guys i found a reliable way of making imac freeze under 1.3 leopard.
    The dock, screesaver etc did NOT make my imac freeze after i updated to 1.3 (it did before 1.3).
    THe way i make it freeze now is i open itunes, start a song, click view, go to visualizer, then OPTIONS. THen turn OFF "cap frame rate at 30FPS". THen make the window larger while playing a song, after about 2 mins my imac freezes everytime (you can even very faintly see the visualizer causing artifacts, although u have to have a strong eye to notice this).

    Hi all,

    FYI -- I've temporarily lost my ability for a surefire way to freeze "on demand" since the 1.2 Update (Tiger) but now it occurs randomly. I'm marking this down as perverted progress...

    I was signing on this morning (Sunday) to tell everyone that Update 1.2 (Tiger) seemed to make things a little better for me. After picking up my iMac from Apple Repair while we wait for the new logic board to arrive, I brought it home, fired it up and got a freeze when opening Aperture...BUT...after the restart, it worked all evening without another freeze. My typical experience until now has been 4-18 freezes a day.

    HOWEVER, this morning it froze three times in a row. First when clicking into just another window in Safari (had to manually restart). The second freeze occurred minutes after (the unit restarted, I logged in, and when the desktop came up it was containing video artifacts from the previous blue screen transiton to the actual desktop. I scrubbed those off with a new Safari window and then it froze). I manually restarted again and it froze a third time on the blue screen during start up. After the third manual restart it allowed me to get to this page...

    I am hoping it will give me another day of relatively "altered state, lower standard good performance" so I can try to catch up on my work projects that have suffered in the meantime. Hoping also that the new logic board when it arrives will round out the progress on the fix. I've never had to wait this long for a part to arrive using my AppleCare Warranty before---you don't think they're replacing so many logic boards there's a squeeze on supply do you? Yikes. Probably just jitters here. Frustrating after my decades' long relationship with Apple products. It's the fact that I know how beautiful this machine works when it's doing what its supposed to correctly that just crushes me when it locks up. I'm reaching the end of the proverbial rope..."Captain, she's breaking up---I don't know how much longer I can hold her together!"

    Will keep you posted on any antics from today's attempts to be productive. Number of days owned: 48. Number of days with freezes: 45 (I'm crediting the tech's word that it did not freeze on him for two days after the update and also one evening when I had it with no freezes early on).

    Hey all,

    I have not experienced any crashes since I last reported. I'm continuing to read this thread and I'm now perplexed by the reports coming in.

    Some users have said that the iMac seems to not crash when trying to force it, but at odd times, the iMac crashed 3, 4 times in a row. This has got be wondering...

    What kind of environments are those experiencing crashes running their iMac in, and those who are no longer experiencing crashes in? What is the ambient temperature? Warm? Cold? Cool?, etc.

    My iMac is located in a finished basement where it is between 70-75° F, 22° C. Reason why I'm proposing this question because it's possible if v1.2 of this update that deals with graphics only is making the problem worse than it could be a hardware problem from the machine not cooling down properly thus making it sensitive to heat. So if the environment is rather warm, the iMac's ambient temperature would be that much higher thus all the other temperatures would be that much higher.

    When this issue first reared it's ugly head, the iMac's graphics would freeze, but the Operating System would function. I'd like to know if those still having the issue are freezing in the same way. When I initially installed v1.2, I locked up hard - Meaning I tried to ping/log into my iMac from another computer on my home network and I could not. Since that initial crash, I have not locked up since. If those still experiencing the freezes are locking up differently, meaning the machine is crashing hard, then it's possible that there problem is not the same as we all thought and that my friends is a big hint to the problem.

    In the mean time, install iStat Pro, a Dashboard Utility, http://www.islayer.com/index.php?op=item&id=7, and monitor the temperatures being read by the system.

    Yes. After continually dealing with AppleCare since I bought mine when they first came out with the Alum model, they want mine back and offered to replace it with a brand new one.

    I started with a completely stable iMac before the v1.1 update and all the troubles began after that all the way up to Leopard and v1.3.

    Anyone should be able to get this if you are among the plagued users. I didn't even ask; they just offered and offered quickly in my case.

    Hi Rick,

    Downloaded the widget and here's the info regarding temps.

    CPU A 106˚, GPU 128˚, GPU Diode 128˚, GPU Heatsink 122˚, Ambient 74˚, Memory Control 117˚, Airport Card 142˚, HD bay 1 131˚. I haven't a clue what the norm is in reference to these readings. BTW, readings are all F.

    Computer is in a comfortable study environment in my home. Low to mid-70's. Freezes are the same. Screen is frozen. Computer continues to run. Cursor is active.

    Update 1.2 has made some marginal progress. I can work more in Aperture (w/Aperture update too). So far no freezes in that. They're more random now....but still occurring as per my earlier post.

    that one is not working for me either... Each machine seem to have its own freezing pattern... Mine is with need for speed carbon...

    Just got Leopard up and running this AM, have not been able to make it crash trying nearly every method mentioned in this thread. I will get WoW going and see what a few hours of that does to it.
