This is a copy & paste from another thread about the "MacFamilyTree" software, some of it applies:
To answer your first question about "FAMILY TREE GENIUS"; this is the PC version of the MAC software "MacFamilyTree". In my opinion, the charting and graphics are quit remarkable; but can be found on other websites, furthermore, I don't find that they are very useful. This really is a game of simplicity BECAUSE it becomes to complicated when you get very far back (i.e. 334 BC). The MAC version does support a vast array of file formats and information processes. Again, though, these can be found in most good programs. Also, the MAC version is LDS compatible so I would imagine the PC version will be eventually. Even with the extensive amount of time spent in the program, I still have not become comfortable with the navigation- there seems to be an excessive amount of 'going backwards'. For more information about this you might want to read the reviews for the MAC version which is normally 3:5. I would probably agree until I get frustrated then it would get a 2.
Hope this helps.
