Family Tree Software Mac

What software to use for my family tree?

I'm doing a family tree of my family and want to include not only parents and grandparents, but also brothers and sisters and cousins and ex-spouses and date of birth and reporting on all. What a good software to use for this (I have a fairly new mac)?

There is a program called "Reunion" Tha sells for $ 100. As far as I know this is the genealogy program on a Mac There are many more free programs with customer bases in the tens and hopeless support. Read more: http://www.consumersearch.com/genealogy-software and http://www.macgenealogy.org/
