Well it appears that ancestry.com is coming out with a mac app. Add that to the list of apps returning or entering the mac market for the first time (CAD). http://store.ancestry.com/ProductDetail.aspx?P=P-4845&o_iid=45865&o_lid=45865 I hope that link works. It is 20% off if you pre-order it. I use the latest MacFamily Tree program that is made exclusively for the mac but I'm tempted to switch to something that sync with ancestry.com. The question (that I initially forgot to add) was if you planned on getting this app, are you transitioning from the PC version, Using Macfamily tree, or a different program. Does anyone have experience with the PC version of Ancestry.com and MacFamily Tree 5 or 6?
