Peter,
What version of mac FTM and what version of Windows FTM are being used?
You can use this tool to convert a file from Family Tree Maker for Mac so it can be opened in Family Tree Maker 2010 or 2011 (Windows); you can also convert a Family Tree Maker for Mac 2 file so it can be opened in Family Tree Maker 2012 (Windows).
