Do you need to defrag?

it's rare that Macs need defragging.

That's because OSX does it automatically on any file under 20 mb.

The only time it may become an issue is if you consistently run with your internal HD nearly full (OSX likes 15% or more free), and frequently add or change lots of large files. Some folks doing very heavy video editing may run into fragmentation problems, but it's quire rare.
