“Widespread anecdotes, including those of MacNN’s own staff, indicate that many owners of Apple’s new aluminum iMacs are experiencing severe interface lockups,” MacNN reports.
“Multiple discussion threads in Apple’s own support forums suggest that many iMacs are occasionally ceasing to accept input, despite programs and Mac OS X itself continuing to run in the background. Some users are reporting that cursors and some keyboard commands may remain functional, but that interaction is extremely limited. In all cases, the only firm solution has been a manual reboot,” MacNN reports.
“Users who have spoken with Apple technical support say that the company is aware of the issue, and that the problem has been narrowed to the ATI Radeon HD cards that power the new iMacs’ graphics,” MacNN reports.

I don’t have one, but that’s not happening to me!

Sounds like a bunch of FUD. The new iMac is Just Gorgeous!!!
I’d still buy one today even if it doesn’t work at all… Goooo Steve!!! Wooooo Hoooo!!
No freezes on my Aluminum iMac in the past week.
2.4 Ghz, 20″.
I had this happen to me once a couple of days ago on my MacBook Pro 15″ 2.33GHz. Wonder if it’s maybe related to the new firmware update that came out last weekend? In my case, I could move the mouse, but not click on anything and the keyboard wasn’t responding. Had to force shut down.
If there is an issue, I hope Apple can resolve it via a firmware or software update. I use my MBP for 8-10 hours every day and it’s only happened once to me, so I can’t say it’s even intermittent, since it could very well be a one time thing for me. Didn’t think much of it until I read this report and noticed the similarity in symptoms. Could be unrelated.
Nothing out of the ordinary here. A bad batch of components (built too close to tolerances), a manufacturer that acknowledges the issue, narrows it down to the particular component and, I’m sure soon to follow, deliver a solution to those affected. It seems to me that this is fairly standard and not unheard of. After all, it is still only ATI (assuming the diagnosis is correct), which is kind of beyond Apple’s quality control.
I haven’t got one either, but it’s happening to me!
My 2.4 GHZ – 20″ iMac froze 3 times yesterday, which required a hard shutdown each time. One time, one area of the display was pixellated.
Actually, my G5 Quad lost it’s keyboard yesterday. Yet the mouse, plugged through the keyboard, continued to work fine. After doing Final Cut and Photoshop all day, a restart seemed in order anyway (to plug any possible memory leaks).
It’s Global Warming™ .

No FUD. This is a real issue.
I experienced freezes using the iLife apps.
Solved it by deleting the iLife apps and doing an install from Install discs over the existing system.
No freezes since last week.
24″ 2.4 GHz Alu iMac is a beautiful machine. Came right in time to replace my 7 year old G3 iMac. I hope the next 7 years will be as happy.
I had this problem several times on my MacBook Pro (Core Duo 1.83 GHz). I think the problem is reasonably reproducible if you attach any external USB (like mouse) and leave it for a while.
It doesn’t happen all the time tho. So, not sure what’s causing the problem.
I’ve had my 2.8GHz 24″ iMac for a month….No problem here.
the same thing occasionally happens to me on my G5 which has an ATI Radeon card. I was wondering why that happens.
No problem here. 68030 Performa running 7.6
I just returned my new 24″ iMac because there was a “hotspot” on the upper side of the display! kind of a white glow!!
Anyone experienced that?
Had it happen a few times to my 24″.
It’s not just the iMac’s having the issue. My dual G5 has experienced the freeze even though iTunes will continue to run even as the rest of the OS becomes unusable.
I chalked it up to iTunes itself, or the fact that I have both a USB and Firewire drive plugged in. I really suspect iTunes.
I love how some people automatically assume FUD. Gimme a break. It’s a real problem. Apple will fix it soon I’m sure.
That’s why Apple should go with NVIDIA.
It’s not only the iMac…
It’s nearly the whole latest patch of Apple hardware that has taken a serious hit on quality.
1: Crooked and otherwise shoddy new iPod screens.
2: Mandating glossy screens, look attractive, but annoying reflections bother longterm users. A choice of matte or glossy would be better.
3: New iMac’s with LESS graphics performance than previous versions!!
It’s looking like Apple is getting shook down to buy:
1: A decent LCD maker
2: Manufacturing plants
3: Nvidia
Apple has always been vunerable to their suppliers.
Take for instance glossy screens, PC makers “decide” they are going to go even cheaper to sell more hardware, attempting to get to “disposable status” where they would make enormous profits.
So Apple now has to go along for the ride because the same manufactoring plants producing PC’s are producing Mac’s.
Apple’s stance on quality has been slipping considerably.
Also there seems to be less “thinking ahead” going on in regards to the iPhone, pricing, inventory and useability. The iPod Touch doesn’t allow “disk access”? WTF??
It’s like Apple is getting worse, it’s “cool” status wearing off, becoming too dominating and controling?
“You’ll take what we give you?” WTF???
I had a similiar scenario were the keyboard didn’t accept the commands or the mouse only made right clicks…
” width=”19″ height=”19″ alt=”smile” style=”border:0;” />
Reason: we got the new wireless keyboard, the small one, set it up, but did not de-authorize the old wireless one nor switched it off.
And depending were the old laid around, stuff got thrown on top of it and keys were pressed… taaadaaaa
It’s happened to me “intermittently” on a Black MacBook. (Core2Duo.) It’s happened maybe 5 or 6 times over the past 6-8 months.
Only one freeze since I got my 24″ Al iMac. Oddly enough it happened yesterday. The mouse cursor still moved around, but everything was basically frozen. No keyboard input worked.
Had to reboot. No kernel panic on reboot or anything like that.
I have a 15″ Dual Core w/ATI Radeon X1600. It has happened to me on several occasions. (although not since I have rebuilt my machine with the latest beta, and stopped using MS products.
There I said it.
No freeze ups to report here. Had mine for about 2 months now. I keep it on 24 hours a day. It’s worked, dare I say…perfectly.
I have the 20″ – 2.4 Gigger. 1Gig ram.
I have not run any games on it. Photoshop works great.
