When I tell people I don’t recommend Family Tree Maker for Mac 2, they often ask what I do recommend, which is understandable. But I really can’t recommend a genealogy program for other people without knowing what their requirements are. You must first decide what your priorities are. Then you can check on the web to see which programs meet your requirements. You can use Ben’s Feature Comparison Table or FindtheBest.com to find the features you need (but take the Smart Ratings on the latter with a grain of salt). GenSoftReviews.com lists lots of genealogy programs, although not all of them have reviews. But see Tamura Jones’ article, The Most Important Genealogy Software Feature.
I still like Reunion and use it for some tasks like searching in my tree because it’s easier and more powerful than FTMM. However, Reunion is pricey—$99, and it’s getting a bit dated. It doesn’t integrate with any of the online databases like Ancestry or FamilySearch. At least it has a demo version, albeit very limited, so you can try it out and see if it has the features you need.
I also like Gramps, which is free and Open Source, which means it’s developed by users. It imported a 33,000-record GEDCOM from FTMM2 without losing any data, despite FTMM’s failure to adhere to the GEDCOM standard. But since it was built to run on Linux, its interface is not Mac-like. It also includes many nice features that are not supported by GEDCOM. At least Gramps tells you what will happen when you export to GEDCOM.
If you try out something else, I recommend importing a small subset of your data to see how well it imports. Use records that are representative of your tree, but also use records that represent unusual cases, like having lots of spouses, adoptions, alternate names, alternate events, Evidence Explained source templates, or anything else that’s important to you. Unfortunately, the GEDCOM file standard isn’t followed very well by many programs, and they will either ignore some of your GEDCOM file that FTMM produces or they will mishandle it. But any decent program will produce a report telling you what problems it found in the GEDCOM. Be sure also to try importing your entire file, just to make sure it can do so without crashing or having any serious problems.
Lastly, you have the option of running Windows on your Mac, either using Boot Camp (if you have an Intel-based Mac) or something like VirtualBox (which is what I use). Then you can use whatever Windows genealogy program you want, as long as you have a licensed copy of Windows and the program. You could also try Crossover (or one of the versions of Wine), which is supposed to run RootsMagic 4 pretty well—without needing a copy of Windows (but you do need your licensed copy of RootsMagic). You can also search in the “What Runs?” box on their website to see if your preferred program works and, better yet, is supported by Crossover. Both Ben and I recommend VirtualBox, and Ben plans to produce some videos on how to use it.
A final note: I haven’t given up on FTMM2 yet. I’m hopeful that Ancestry and Nova Development, the actual developer of FTMM2, will fix the bugs and include all the features that are in the Windows version. But in the meantime, I’m testing other programs, both for the Mac and Windows.
