GLSL isn't available on the mac... and god knows if it ever will be. You'll have to read up on the assembly-like ARB_fragment_program 1.0 -- I recommend _The OpenGL Superbible_. It's a good resource, with a lot of working sample code.

and even if GLSL was supported, the asnwer would be "no" -- cocoa GL sample code is here, http://onesadcookie.com/book.html . GLSL sample code is all over the web. If you need help combining them, you should be starting somewhere simpler!

You don't need GLSL or fragment programs to do "per-pixel lighting."

ARB_texture_env_dot3 will do per pixel bump mapping, and works on a plain old Radeon or GeForce 2MX.
