What do you need to save a word document as so that a mac can read it?
If the Mac has Word installed it can read a Word .doc file -
although there are variations between different versions of Word
which may cause problems. Even without Word the Mac's TextEdit
application can read basic .doc files. There are free applications,
such as Open Office (or Neo Office), which provides a high level of
compatibility with Word. If the document is only to be read, and
not edited on the Mac, then saving it as a .pdf will ensure that
the Mac sees the document, with all its formatting, as
intended.
