I hate it when this happens. :-P

Note that this post ONLY refers to:

*INTEL Macs*

PowerPC Macs are NOT affected.

The original Mac OS X 10.4.7 update for Macintel machines was missing
files related to OpenGL. DO NOT USE THE ORIGINAL UPDATE. Use the newly
revised version that corrects this problem.

What if you already ran the incomplete update?

It is possible you can simply run the new update and you will be fine,
but I have NOT verified this to be the case. For now, head over to
Macintouch and MacFixIt for advice:

I will post new information in this thread as it is discovered.

Below is Apple's Security Announcement regarding the release of this
revision.

Fortune Magazine, 11-29-05: What's your computer setup today?
Frederick Brooks: I happily use a Macintosh. It's not been equalled for ease
of use, and I want my computer to be a tool, not a challenge.
