Symptom
The computer restarts to a blue or gray screen after installing Apple Display Software.
Solution
Reinstall Mac OS X 10.2 to resolve the issue. Because the necessary software is already included with Mac OS X 10.2, you should not install Apple Display Software.
Note: It is not necessary perform an Erase Install or Archive and Install, unless you have updated to a later version of Mac OS X than the one included on your software installation CD.
