I have converted your family tree to an online editable version.
In the future we plan to add an option to edit the family tree both on the online website and the FamilyTreeBuilder at the same time. But in the meantime users need to choose which editing platform they prefer.
Thank you for writing to us.
As explained in this post, it is not possible to download the Family Tree Builder to Mac computers. If you wish, I can convert your tree into a Web tree, that can be edited directly online.
