I found the book OpenGL: A Primer to be a good introduction to the subject. I starts off with the most simple thing (drawing a white square on the screen) and progresses slowly from there, introducing new OpenGL calls and techniques as they are used. This is not a comprehensive OpenGL book, but it actually covers quite a bit, enough to keep you busy for a while. The code is also all non-platform-specific. There are a few quirks your need to discover when using OpenGL with Cocoa, but I didn't have a problem using it on a Mac.
Depending on your needs you may also decide to spare yourself the trouble of learning OpenGL and use a 3D engine which may simplify development. A lot are free but quality varies. I can't really recomend which engine would best suit you.

i agree, red book and blue are important. once you read a bit of the books, your see a lot of people on nehe.gamedev.net have read that same books as well.
That tutorial will guide you through all the basics. Sticking shapes on the screen, text, input from keyboard. You can build on from there. You should be able to write a simple game like Pong using just what you learnt in that tutorial.
