I am convinced that a lot of the freezing issues are caused either by bad RAM or a bad video chipset.

My sister had a new iMac and it frooze four times right out the box during the installation of the Apple Software Updates.

When you have these problems, the first thing Apple will want you to do is reinstall the OS. When I said it was freezing RIGHT out of the box, Apple said it might be a bad software install at the factory.

So I booted off the install DVD and when I went to the Disk Utility to erase and format the drive, Disk Utility started to show problems. I had a 3 inch space between some of the tabs (First Aid, Erase etc) when there should not be any spaces. So Apple confirmed it was a HARDWARE issue.

My recommendation to those with freezing iMacs is to do the following:

1) Run your iMac for 2 hours playing games. using Skype etc
2) Then boot off the DVD install disk and run some of the programs (like Disk Utility). BUT do not reinstall the OS. If your iMac freezes or shows weird graphics etc, it DEFINITELY is a Hardware issue (at least in Apple's view).

I know some are suggesting that the iMac Freezing problem is a software issue. But where is the official Apple note acknowledging this?

I have bought two Macs during the past year and BOTH had to be returned for hardware issues. The quality control for the recent Apple products leaves a lot to be desired IMHO.

v1.1

For anyone wondering, this will update the ATI Graphics Card drivers, and the "GLEngine" (presumably something to do with OpenGL).

To see what files it installs, run the installer and choose "Show Files" from the "File" menu before clicking the "Install" button.

I don't know why its so hard for Apple to provide even a little bit of information about what they expect us t install.

Smooth update. No issues.
