By default, Microsoft Word for Mac uses a different format (.docx) than earlier versions of MS Word on Windows (.doc). However, you can easily change your Word preferences so that your files are saved in the .doc format:
- Open Word and click on the Word menu
- Click on Preferences
- Under Output and Sharing, click on Save
- Under Save Options, “Save Files as” (bottom of list), make sure “Word 97-2004 Word Document (.doc)” is selected.
- If not, click on the blue arrow and select it from the list.
- Click OK
Note: This only applies to new word documents. If you already have a .docx file, you will need to click on the File menu, click on Save As, and use the blue arrow to select “Word 97-2004 Word Document (.doc)” from the the list.
