I am still waiting a few days until I call..

If anyone does decide to call sooner, would you mind posting your results here?

I recommend that you take your iMac back for an exchange if the fix doesn't arrive by tomorrow. You don't have much to lose and seems to me like it's a hardware issue. Just keep exchanging it until you get one that 'just works'.

Remember lots of people don't have the freezes.

Lots of people said they didn't have the negative screen issue with week 36/37 ipods, which turns out ALL of them had the problem... Don't believe everything you read..

Additionally how am I supposed to exchange a BTO iMac?

That is something I would have to send back for repairs correct? Then it would come right back to me saying apple could not reproduce the problem...

Apple is aware of this issue and the finger right now is pointing to the HD2600 Graphic Card. If you send it back for repairs I think they will change it for you. If they don't then I suppose you'll just have to wait for the promised fix/class action.

The last time I spoke to an Apple rep about this (last week) they were completely unaware of the issue (or at least claimed to be). If Apple can't reproduce the freezing (and it is random so there is no guarantee they will) they won't replace the card. Even if they did replace, you still might end up with a bum one.

Apple is known to keep issues secret before they fixed it. This totally contradicts Steve Job's quote doesn't it? :p

Steve Jobs said:
Sometimes when you innovate, you make mistakes. It is best to admit them quickly, and get on with improving your other innovations.

As I said you can still send the iMac back and if they 'claim' there's no freezing, just wait for the fix/class action. If they can and replace the HD2600 then good for you. I don't think you'll get another faulty one if Apple directly fixes it (sorta like that 'technician' case).
 
and the finger right now is pointing to the HD2600 Graphic Card.

If you can cite that source then it might hold some weight. (Please don't give me a link to another discussion board).

Fact is, all you have is a uneducated hunch...

Sorry.
 
Apple knows about this problem, and they probably know how to fix it; replace the GPU chipset and/or ROM with certified "good" samples.
The chances that this widespread issue has not manifested itself in one or more of the Apple Stores is slim to none.

What makes you think it is hardware related?

Apple issued a statement saying it was a software fix...


I think there are way too many chicken little's around here... The sky is falling! The sky is falling!
 
I've got a 24" 2.8 and had problems since day one. I hung out until I got Leopard - now it is worse. I've now logged a call with Apple support to fix the issue.

Alot of post have refered to apple knowing about the issue. Could someone please post a link to the apple website? I cannot find a single apple resource indicating they know.

Thanks in advance.

No problems with my iMac here (specs in sig).

It's left on 24/7 (without sleep) and I've yet to experience any kind of hard UI freezing. This is both on 10.4.10 and now with 10.5.0. I also installed the 1.1 graphics update.

However, the screen does show non-uniformity in both brightness and colour, so it's going back for a replacement.

I just hope the new iMac doesn't suffer from either screen or UI freezing issues.

"A small number of iMac users have made us aware that a recent software
update issued by Apple can sometimes cause their iMacs to freeze ... "


How can "a small number of iMac users" have a software problem?

...does Apple transcribe the DVDs by hand?

Is a refund possible

I am one of those affected by the freezing problem. It happens most often when I play WOW in windowed mode and when my Adium "bounces" on the dock when a new message arrives. Taking the machine back to the shop over and over again until they give you a good one sounds impossible for me since I don't have a car.

So is a refund possible 3 months after I bought the machine (bought in Aug)? I mean, since this is not what I paid for in the first place.

You care not reading it correctly...

Just saying they have gotten a small number of complaints.

Firstly, we all know that the iMac is more likely to freeze under heavy GPU load.

Secondly there's this:
http://www.tech.co.uk/computing/mac/news/ati-graphics-force-imac-freeze?articleid=1376644803 said:
Apple has apparently blamed the problem on the ATI Radeon HD graphics card inside the iMac, but a fix has yet to be issued by the company
Appleinsider also believes that the HD2600 is most likely the culprit. Many sites are pointing the finger at the HD2600.

Thirdly, In the post I found earlier, the person's iMac apparently stopped freezing after his graphic card was replaced.

Yes, it's a hunch. Of course I could be wrong. There's no definite proof, but it's a good hunch. ;)

The only information I know of was released to Macworld.com.

It can be interpreted many different ways by different sites, but at the end of the day Apple is claiming it is a software fix.


P.S. It is not a good hunch. You have nothing to support it. Those sites you cited were talking about it being linked to HD2600's DRIVERS. (That would be software).

So what if one user claims he had his GPU replaced... This means nothing. He could either not know what he is talking about or just plain old be lying. Replacing the GPU is not an easy task by an means with an iMac... Not even sure apple would opt to do that on site...
 
The video driver in my 24" iMac works perfectly.
No freezes, crashes or KP after almost two months of daily use.
I guess my copy of the driver must be one of the good ones.

edit: Place tongue firmly in cheek; write stupid post.
The proper diagnosis for this problem is straight out of the computer troubleshooting handbook for dummies.
If it isn't the video chipset firmware, I promise to be appropriately shocked and bewildered.
LOL

ALL the "copies" are identical.

This problem is known to be "fussy"

In Tiger I would have 6 crashes in a day and then go 2 weeks with the computer 100% stable. No idea what brings it on.
 
This thread's been a great source of info! I'm in the market for an iMac, and I've got the option to buy the white 2.16Ghz model (24") at a HUGE discount, or the new one at regular dscounted prices (Gov't/educational). From the sounds of things, I just may opt for the deeply discounted, but older iMac... although I hate the idea of buying "already obsolete" hardware... :p
FWIW, is the upper limit of RAM on those white models really limited to 2gig, or is that just a reflection of what was avail on the market when they were new??
Also, were there any common hardware issues I should be aware of with the 24" 2.16GHz White Core Duo models?
Thanks

3GB max on the older ones...


I used to have a white 24" 2.16... Worked great!

Aw Hell- 3 Gigs isn't bad! :) I think I can live with that. I'm not convinced that I'd really notice the difference in speed between the two chips anyways, since I don't play games or anything (although, with that big screen it might be fun!). iLife apps are about the most demanding things I'd be doing. Besides, I'm currently on a 1Ghz G4 with 1 gig... it's gotta be faster than this!

For the people with the Aluminum 24s that lock- I know that the rumor is that it's related to the ATI card, but what's the evidence for that?? In the past I've had some of the pc's I put together "freeze" when I used el-cheapo memory. I'm sure it can be anything, but since multiple things trigger the freezes, it seems more likely to be a latent hardware problem waiting to be unmasked (like accessing a chunk or bad memory).

the evidence is that Apple themselves have pointed the finger at the video card. I have replaced my meory with high quality RAM and still get freezes. I have also tested the RAM for errors. It passed.
