When a Mac user wants access to an editor, I am willing to bet a software program like BBEdit is exactly what they have in mind. Designed with the user in mind, BBEdit allows for editing, searching, and the over all transformation of your work. I have heard a lot of good things about this program.

BBEdit is a high-performance HTML and text editor for the Macintosh. It is designed and crafted for the editing, searching, transformation, and manipulation of text. BBEdit provides an array of general-purpose features which are useful for a wide variety of tasks, and includes many features which have been specifically developed in response to the needs of Web authors and software developers.
