If you wish to continue your Ancestry subscription you might as well purchase FamilyTreeMaker, which comes with 6 months free membership. Make sure you purchase the version which gives the worldwide, or local, subscription that you require. You can upload your tree from Ancestry and import it into FTM. I don't know "macfamilytree" but I'm sure you should be able to export your tree in .ged file format and likewise import into FTM.
The charting options in FTM are good, whatever you may think about the rest of the program.
