you are right--the mac forum has been dead for months. However I will never return to the awful windows world after escaping on retirement.
I have just finished testing all of the native mac programs with disappointing results:
FTM 2019 is OK except all text is very small and cannot be adjusted. Media is dumped into one folder and you have to fight the program to use subfolders although you can categorize each item. Websearch is so so. Hints are great.
Reunion has no pdf or print manual you can peruse and the person screen splits information into name, event and fact sections requiring clicks to reach. I am comfortable with their source and citation approach where essentially all information is in the source. This avoids the confusing overlapping fields common to other programs for sources and citations.
macfamilytree has a horrible pedigree or tree display and the person view requires much scrolling to see media event..facts etc. Text except in the tree view is good. No print manual and the few reviews are not very positive. Great familysearch integration.
heredis has tiny instead of very tiny text but support and knowledge base are just what you would expect from a french company. Both heredis and MFT bundle media into the database which makes for a large file but no broken link issues.
Rootsmagic 7 has a lot of windows quirks on a mac and looks awful but you can make the text quite readable and the person screen is outstanding. All data displayed at once with sources, media and notes a click away. If RM8 ever appears and you can still make the text readable I will jump at it. For now I plan to clean up my 350 person RM7 file and hope for RM8. Unfortunately Bruce demos RM8 on windows so I am unsure if the mac version will have readable text size.
