In the past couple of days both MacFamilyTree and FamilyTreeMaker for Mac have received updates.
MacFamilyTree was updated to version 6.0.11 which offers some minor web-output related fixes and some localization updates. You can download the update from their website, and for those who bought it via the App Store presumably it will show up there soon.
FamilyTreeMaker for Mac was updated to version 126.96.36.199 (yeah I don't understand their numbering system either) and fixes 'numerous stability issues' and adds support for the GEDCOM 5.5.1 draft among other fixes. I'm surprised about the GEDCOM update, by which I mean I'm surprised FTM for Mac didn't already support the 5.5.1 draft which was released in 1999 and has some very important updates like support for Unicode. If you have the retail version, this update should pop up when you launch the program or select 'Check for Updates...' from the menu. If you have the version from the App Store, again this will probably show up soon.
I own both of these programs, but do not use them very much because of two factors:
1) It's hard to switch from one genealogy program to another, no matter how well they support GEDCOM.
2) As outdated as the Reunion is, and how much I complain about it, I still like the general user interface of Reunion and how it displays families in the program.
I've written previously about trying to switch to FTM for Mac, but I was unsuccessful mainly because of the difficulty of importing all the media files, and my general confusion over the user interface which I find very cluttered. In addition, I find the Internet features, while appealing, to be very slow.
I haven't given MacFamilyTree its due I suppose, and many people like, but as I received it as part of a software bundle and didn't actually buy it directly, I guess it hasn't gotten enough mindshare from me. One day I'll have to put it through its paces.
