OS-X versions of TABARI run in the Terminal application, which uses a Unix "command line" interface. Downside: no fancy eye-candy and menus. Upside: this is the standard interface for Unix research software and it is easily maintained -- it took only half an hour to convert 5-year-old Linux interface to run in OS-X, and subsequent versions should run without modification in both OS-X and Windows.
To run real data, move your coding dictionaries and text files into this folder. If these were created in an earlier Macintosh system, they will need to be converted to the Unix format used by Terminal applications. This can be done using BBEdit (open the file, then click the fifth icon from the left, then select 'Unix' and re-save the file), or using the free (! -- and "free as in beer") program TextWrangler 2.0 (the program formerly known as "BBEdit Lite") from those wonderful folks at Bare Bones Software.
If you want to set up version 0.4.9B2, just follow the same instructions but change the name of the program. Same with later versions of 0.5.
The program can be located anywhere; the directory suggestions
given above use /Applications/TABARI for simplicity. And yes, real Unix programmers use
tr '\r' '\n' < mac.txt > unix.txt
to convert the files.
If you prefer XTerm to Terminal, the program works fine there as well.
