We, the undersigned, request that Apple Inc. officially acknowledge and address the defect in the Late 2006 Intel iMac.

The defect causes the following symptoms:
* System shuts down unexpectedly.
* System display freezes, preventing any input.
* Horizontal black/multi-colored lines appear over the desktop or app windows.
* Various colored squares/triangles appear over the desktop or app windows.
* Random colored pixels appear over the desktop or app windows.
* Squares displaying parts of other app windows appear over the front app window.
* Tearing or fragmented app window displayed when scrolling.

These symptoms usually appear after the one-year warranty period has expired.

Heat is a contributing factor. As the internal temperature of the system rises, there's an increased chance that these symptoms may appear, even though the temperature isn't unusually high. Symptoms start to appear as the GPU temperature approaches 50C/122F.

Many users who are experiencing these symptoms have resorted to installing a third-party fan control application to increase the internal fan speeds. This workaround may relieve the symptoms temporarily for some users, but does not actually fix the core defect in the hardware (logic board) that causes the symptoms. Increasing fan speed is not an acceptable long-term solution.

We ask that Apple Inc. do right by their loyal customers and directly resolve this matter by issuing a product recall and making the appropriate repairs free of charge.

    • 43C is where the danger zone starts for my iMac. That's when I start seeing glitches and the entire system freezes or shuts down sooner or later. This started happening about 6 months ago, when my iMac was about 18 months old.
