Currently Being ModeratedSep 24, 2007 4:52 PM (in response to Rick Bargerhuff)Apple doesn't "need" to tell you anything. Their obligation is to investigate and solve the issue. I would seriously doubt that replacing your iMac is the solution they would choose and nor are they obligated to under the terms of the warranty that you agreed to when you purchased the item. It may require nothing more than a simple firmware upgrade of the video card.
Apple has a good track record of fixing things as they become aware of them. I suspect they will solve this issue also. If not then that will be time to take a different course of action.24"imac 2.4Gz, 17"iMac core duo, 20" G5 iMac, 20" Intel iMac, Mac OS X (10.4.8)
Currently Being ModeratedSep 24, 2007 4:58 PM (in response to Pop!)I'm having a problem that seems related to all of this, but I may have a pretty decent control situation. I just unboxed a brand new 20" Al iMac. Came with 10.4.10 right out of the box. Booted up, paired my Apple Wireless Keyboard and Wireless Mighty Mouse, and connected to my WEP 802.11b network. Started downloading Apple's Software updates, including iMac Update 1.1. Walked away from the machine.
Came back expecting to find the computer asleep, but all of the updates applied and just waiting for a reboot. No such luck. Screen was black, and the keyboard, mouse, and even the power switch wouldn't wake the machine. So I held in the power switch on the back of the iMac to forcibly power it off, which worked.
Machine rebooted fine, and seemed to be working OK. Sent the crash report to Apple, as the iMac requested. Installed a couple of pieces of software (Office 2004, Flip4MacWMV, a few others), and all went well. Machine works, sleeps, wakes, no problem. So then I reboot.
Machine appears to reboot OK, but stops when the wallpaper appears and the mouse pointer is on-screen, but the desktop, Dock, and Finder never appear. The mouse moves, but there's nothing to click. Can't do anything, not even put the machine to sleep. Force the power off again by holding the power switch.
Since then it's been OK... but two crashes on a brand-new machine straight from Apple with no extra RAM, etc., within a 12-hour period, less than 36 hours after taking it out of the box. I'm a bit nervous.
Do I have reason to be?Al iMac 20", Mac OS X (10.4.10)
Currently Being ModeratedSep 24, 2007 6:08 PM (in response to Pop!)I would be very surprised if it's a hardware issue. I really think (could be wrong) that a software update with new drivers will come soon and solve the problem.
I was one of those that was looking at others having freezing problems without having any myself. But yesterday (after almost a month without problems), it happened 3 times to me too, with the mouse cursor still working but everything else frozen. The first time I noticed something weird was happening when I was encoding with iDVD and there is that small image where you can see the images/video being encoded and suddenly those images started to show artefacts like pixelation, all green or pink images (the rest of the display was perfectly fine) and suddenly no more response from the computer. I had to manually turn it off. Then it happened 2 times more when I was in FrontRow, I was looking to a trailer and pressed escape before the end of it to go back, the screen got all black and again I had to reboot again manually.
It seems obvious to me that there is a problem that is not related to user installation and graphic related. I hope Apple finds a solution fast, it's bad publicity.Powerbook 1.33 17, soon iMac 24", 2.8 GHz, 4 GB RAM, 500 GB HDD, Mac OS X (10.4.10)
Currently Being ModeratedSep 24, 2007 6:27 PM (in response to kkat69)Mine is locking up pretty regularly in FinalCut Express, usually while playing back or scrubbing through video.
I was able to ssh into the machine as others mentioned. I put it to sleep then woke it back up. That allowed gaining some control but there were artifacts on the screen and the computer had a kernel panic shortly after. The log showed it as a graphics driver problem.iMac 24", Mac OS X (10.4.10), 4GB memory
Currently Being ModeratedSep 24, 2007 9:29 PM (in response to Pop!)BTW, here's another good way to torture-test the iMac's graphics. This is what I was doing when the first freeze occurred after 1.1.

EVEN WORSE: I tried the rollback "trick" and the next reboot gave me the blue screen (of death) before the login window.
The Macrumors forums suggested a PRAM reset after the rollback. I did this, along with an SMC reset, disk repair, permissions repair, and manual execution of the CRON jobs ("sudo periodic daily,weekly,monthly"). The entire afternoon and evening, there wasn't a single freeze, blue screen, etc. I ran iTunes, iPhoto, Quicktime (with 1080p movie trailers), and even rolled over the Dock a bunch of times. A rebooted a few time as well.

Currently Being ModeratedSep 25, 2007 7:18 AM (in response to KesslerB)Hello KesslerB,
I am not sure if it helps. I have a 20" Alu iMac and had a problem with software update 1.1, which made me had to reset the SMC everytime before I can power up the machine.
I finally determined to restore the default system without software update v1.1, the problem has gone and my iMac works flawlessly now.
it worths to give it a try to restore the default system and it takes only 30mins to complete.
I am more than happy to share with my "about this mac" information for your reference, just let me know.

Currently Being ModeratedSep 25, 2007 11:17 AM (in response to KesslerB)Kessler - you describe the exact same problem i am having. i also tried doing the 1.0 rollback and it didn't help. i'm not getting any graphics freezing as the others are, but i still cannot restart or shut down. exactly as you describe - just get the desktop image and mouse cursor.
have you been able to properly restart or shut down since your post??iMac 24" 2.8 c2e, Mac OS X (10.4.10)
Currently Being ModeratedSep 25, 2007 12:27 PM (in response to Helicon Twist 2008)Has anybody out there totally reformatted the computer from scratch and then put on the software update and it work? Applecare told me that was what I needed to do at this point then they would have to replace the computer if it didn't work. I've got my computer to the point is usable doing archive and install but still notice glitches in various software. I also do not feel comfortable with the fact the only solution to the problem is avoiding the update. Why can some people download it and others can't. So if anybody can answer my please let me know.Imac, Mac OS X (10.4.10)
Currently Being ModeratedSep 25, 2007 12:59 PM (in response to Pop!)Having persisting issues with a 2.4GHz 24" 4GB machine here pre/post 1.1 software update. Primarily only using it for Motion 3.0.1. Having some rendering issues (like artifacts of previews from the file browser, even though those assets aren't being used), and significant crashing issues. Typically the machine will lock up, mouse moves, will change back and forth between pointer and beach ball, dock is unresponsive, and so is force quitting. Happens pretty much on a daily basis.

Currently Being ModeratedSep 25, 2007 1:05 PM (in response to mzd)MZD: The symptoms I've described have only happened once each, so yes, I've been able to shutdown and restart successfully since that incident. Having said that, the machine has been sitting on a table unused for the past three days as other commitments have prevented me from enjoying the iMac. Give me a few more days, and if there's anything worth reporting, I'll be back here.iMac 20" Core 2 Duo @ 2.0GHz, Mac OS X (10.4.10), Stock video (ATI Radeon HS 2400XT with 128MB)

Currently Being ModeratedSep 25, 2007 6:07 PM (in response to Chris_Delbuck)The problem my iMac suffers from (GUI locking up in UT2004) now also happens when booted natively into Windows XP with a PC version of the same game. The symptoms are nigh on identical.
Initially you would think this must confirm bad hardware. But keep in mind Apple (along with ATI) put together the graphics drivers in bootcamp 1.4. Also keep in mind that there is no such iMac v1.1 software updater for Windows. So the graphics drivers in XP must be older.
So the software/drivers may still be the culprit.. I honestly don't know at this stage. However, some of our iMacs suffer more serious graphics related issues than others. If it was a software problem, would our iMacs issues not all be much more similar? (besides all clearly being graphics related) Where as presumably some hardware fault may manifest itself in several different ways.
It locked up regularly in OS X with the v1.0 update.
It locked up regularly in OS X with the v1.1 update.
Now it locks up in the same way with Windows XP.
Note: All 3 arrangements still contain Apple/ATi drivers.
Software or hardware? After all this time and messing about, it still seems somewhat 50/50 to me. So either the software/drivers in all 3 setups is seriously 3rd rate. Or its a hardware fault.
