Here are my recommendations base upon testing and usage: Updated!
Roots Magic 6 & 7 these are windows applications but can be run on MAC's via MacBridge (a customized version of Crossover) for 9.95. You will still need to purchase a full version of Roots Magic (for the license file key to use in MacBridge). Is MacBridge as good as the windows version? Sort of you can open your family information just like in Windows. the MacBridge application is stable. Someday soon Roots Magic promises a true OS X app. They have an iOS app but it is read only of your Family file so it is useless if you are away from your MAC, you can't add information with the iOS to your family file.
iFamily is a great genealogy app for the MAC, it is easy to use and support importing of data via gedcom files up to version 5.5. iFamily for Leopard is a genealogy application for people who think differently. Whereas other genealogy software tends to emphasize the family unit, this software's focus is on each individual person. This distinction is subtle and is a feature of iFamily for Leopard. In iFamily for Leopard you can see at a glance whether an individual has more than 2 parents, more than 1 spouse or the number of siblings they had. Parent-child relationships may be natural (the default), step, adopted or foster relationships. Available for purchase since October 2006, iFamily has had more than 60 versions released, leading to a richly featured product that is stable and user friendly, utilized by a healthy community of users.
Pros: great support forum, customer focused. Cons: no iOS application.
Reunion is another really great app for the MAC, it is simple to use and has a Mac World Editor's Choice Award: Reunion is a genealogy software program — a "family tree program" — for the Macintosh. Reunion is also available as a companion product on the iPhone, iPod Touch, and the iPad. The current version of Reunion for Macintosh received the highest rating for genealogy software in MacWorld, MacAddict, and Mac Home Journal magazines. Reunion also received a MacWorld Editor's Choice award. The latest release 10 (2012) the upgrade price 49.95 (unless you are in PA then it is more)..
I bought this app because it was suppose to the be the best genaelogy app for the MAC (2009) , at the time it was now not so much.
Pros: Great user interface (UI) good documentation Cons: iPad app cost 15.00 and you proably shell out 100.00 for the mac app that you must have in order to use the iOS app.
Mac Family Tree is a very visual applcation for the MAC. I have been using this app since release 3 (now at release 7), the developers have made great strides in the user interface! The reports and charts are first class! Your family tree:
Easily enter and then visualize your family history. Be it creating reports, diagrams or browsing your data in the innovative 3D view called Virtual Tree - MacFamilyTree offers a solution for every task. Get an overview of where you hail from and maybe enthuse your relatives about exploring your family's past at your upcoming family reunion.
Pros: Great UI, activily being improved, very visual, resonable price for product and updates, iOS app 15.00, iOS app can import and export gedcom files. New 7.x version is out and is a huge improvement over the original 6.x software stream
Cons: Version 7.x for IOS does require that you repurchase the application. Issues with the current release importing and exporting gedcom files even from older releases, iOS app freezes up when using large family files (31 to 43 Mb) **note this has been fixed with the last application update for iOS **, must have desk top version of software to sync data on the same WiFi network. Syncing of data takes forever on large files or just plain crashes both sides. Tech support is germany, slow responses at times. Web site is confusing since they have multiple products.
