It's probably better to use VBOs. There are some explanations and short code snippets about VARs and VBOs in:

OpenGL Programming Guide for Mac OS X

specifically, the section called Techniques for Working with Vertex Data

Just wanted to add, VAR dates from prior to VBOs. Now that the APPLE_flush_buffer_range extension exists, it provides no advantages over VBOs. My understanding is that future Apple optimization efforts are focused on VBOs, not VAR.
