Two files to help convert ArcView EPS files into something that can be opened in Illustrator or Freehand on the Mac.
We needed to use both to edit files in Freehand 9.

epsConverter -- Works Great on Freehand
epsConverter is a Mac program and you will need to unStuffit to use it. It works on Freehand 9.
You can also download it from the Art Age web site

Export Wizard, an ArcView plug in for Illustrator. Instructions are in the documentation provided. We had to export a new EPS using Export Wizard before we could successfully convert it using epsConverter.
