yes....according to what I've read, openOffice ( LibreOffice will open PC publisher files, otherwise, when you are using Pubisher for PC, one of the only other options that I know about (there may be others) is to save the file as a .pdf on the PC side and then export it. It will then open on the Mac no problem, oh, and you can save it as a word document (.docx), to do this, open the document you want to conver using MS publisher 2010 for Windows, press Ctrl-A, to select all the content, then Ctrl-C to copy to Windows Clipboard, Open a new blank MS word 2010 document, Press Ctrl-V to paste the clipboard contents into word, then click
save button on quick acess toolbar, and the resulting document can now be moved to your mac.
