I can't find any way of entering marriages. Why doesn't MacFamilyTree show me marriages in the Person Events?

Weddings are Family Events in MacFamilyTree. Please see the User Guide in MacFamilyTree's Help Menu. Page 21 details all steps required to enter a married couple in MacFamilyTree 6. Page 25 explains the difference between Person Events and Family Events in MacFamilyTree.

More information is available in the User Guide. You can find it in MacFamilyTree's Help Menu or for download here.
