thanks for the tips!

all screen savers work

all itunes visualizers work

will test timemachine next

I'm a happy mac switcher again!!!
 
Just got my Leopard UTD 48 hrs ago and have installed it and that includes the 1.3 update. Ran the Arabesque SS for about 5 minutes then Shell SS, ran iTunes visualizer, Dock test and no freeze not even a sign of one. I guess that concludes my iMac isn't affected by this issue.

Hopefully those with this issue get answers from Apple ASAP

EDIT: My iMac is a week 31 model

which part of the serial number is the week build?

I tried to run a serial number survey on the apple.com forum site but they deleted all reference to it

here are the serial numbers that froze (before they deleted)
W87095YXXXX
W87302XXXXX
W87312YXXXX
W87331FXXXX
W87333HXXXX
W87334HXXXX
W87336HXXXX
W87337PPXXX
W87362AXXXX
W87394HXXXX

my new machine is a w87396qxxxx

I asked people to leave off the 4 characters of their serial numbers for privacy
 
Mine is W8729... and my iMac freezes a lot. So I guess week 29 models suffer from this issue?
 
Week 32 here and I get the problem every few weeks for about a day at a time.
 
W87311R...

Big freezer *until* 1.3 in Leopard. Has been totally solid since I installed Leopard and the update on Friday.

Would barely run for a few seconds before freezing with 1.1 under Tiger.

No sceen artifacts - freezing only.
 
Well, week 44 (W8744XXXXXX) is on it's way from China via FedEx as we speak. Should be here on friday the 9th. I sure hope it's not a bricked freezer. That's a lot of money for a paper weight.
 
Not Freezing here

iMac 24" 2.4 with 2GB Apple-installed memory, and no freezing at all. Whew.

W87420YXXXX

I am not going to install 1.3 until I hear more about its effect on non-freezing iMacs.

My mac has yet to freeze and I ran Tiger, Tiger w/ 1.1 and Tiger w/ 1.2, then Leopard and now Leopard w/ 1.3
 
Hi to you all, another new iMac user here :).

I read a lot of stuff about this freezing issue, and I'm very scared, so I'd like to post some question for those who know about this subject more than I do. And please forgive my english if something it's unclear.

Up till now the only issue I got with my 20" 2,4ghz (1 GB original ram, I'm planning on adding another 2 GB from Crucial) has been a fair amount of kernel panic, the one when a gray screen appears on boot with the message in 4 languages saying to manual reboot the system. I think those are related to my old usb modem, and since I repaired the disk permissions and replaced the modem it never happened again.

What I wanna ask is: what can I do to test if my iMac is one of the freezing one? I read I should try the arabesque screensaver, but I can't find any screensaver with such a name! What is its exact name? And how can I try to freeze the mac, should I run it in the preview window o it must be set at full screen? Then I read iTunes visual effects can cause the freeze, and I'm now running it in background: it sometime slowdown a bit, but not freeze so far. After how much should the freeze happen? There's some other test I can run to verify if I got a freezer instead of a Mac?

Thanks for reading, and sorry if these questions have already be posted, but as I told you I'm new to the Apple scene.
 
Arabesque is only in Leopard. If you take a Photobooth photo of yourself, transfer it to iPhoto (via the iPhoto button in PhotoBooth) and then continuously spin the photo around in iPhoto you may get a lockup that way. Also moving the mouse back and forth rapidly over a magnified dock does the trick for some. Good luck.
 
W8741XXXXXX here sans ALL updates.

3 freezes total, one suspect since I was resizing a window with WoW in it ... none since and I have tried to ... tried the WoW window resize again, iTunes visualizer large screen mode with FPS cap removed, fast scan of dock, iPhoto ... it doesn't run Leopard yet (still antsy about upgrading in any form) so no TimeMachine test for me. WoW has been running fine for a week. My wallpaper changes every 30 minutes, my screen saver runs for 15 minutes before the screen goes to sleep ...

Stumped. Why would it freeze 3 times and then never again? Is that even possible?

That's what I observed when I first patched. It froze a few times immediately, then it was as if the system just kinda settled. Is it possible the software continues to update files after restart? I dunno, but I have been fine for days now.

Have you run any graphically intensive stuff, and then rebooted shortly thereafter?

I ask because everything seemed to be going great for me since 1.3, but I played WoW for a bit this morning, then restarted and found the machine froze up right away again. Another reboot - same thing. Zapped the PRAM x6 and it was back up and running.

Wondering if you've found the same to be true, or if you wouldn't mind testing it out :)

Thanks for your help :). I tried both methods and maybe I'm lucky, the mac didn't freeze. My sn is W8739DXXXX. I'll try again with iTunes visual effects later, I want to be sure I do not need to return it back in warranty.

Yep. I played WoW all weekend without a hitch. Immediately after the upgrade, I ran WoW. It froze. Restarted. Froze again. Turned the iMac down in frustration and went to bed.

Next morning. Powered it on. Crash. Really Really peeved. One last thing to do. Reset PRAM. I reset it more than once. Usually after the "chime" gets a but louder during the reset.

Didn't want to stress the system as I had email to answer, I worked on the iMac for a bit without running WoW. A few hours later. WoW started. Never looked back. Been good ever since. Weird, I know.
