Hi - I'm happy to help with your Mac issue. Please remember to Accept when we are completely finished and you are satisfied with my answer. There is no direct way to do it, but there is a web based service that can convert the file format back and forth. Try this:
Use Zamzar.com online. It's free and it works. Upload your .pub file and it'll convert it and email it back to you in its new format. It will change .pub files into...From .pub - Microsoft Publisher to:doc - Microsoft Word Documenthtml - Hypertext Markup Languageodt - OpenDocument Text Documentpcx - Paintbrush Bitmap Imagepdf - Portable Document Formatpng - Portable Network Graphicps - Postscript documentrtf - Rich Text Formattxt - Text document
Then you can use any text editor or word processor to read it on the Mac.
