As you know, one of the problems with a Mac operating system has been the lack of software resources for Bible studies. There is finally a dedicated Mac Bible study software program that is outstanding. It is called Bible Analyzer 4. Very similar to e-Sword (for Windows), you will find it very intuitive and easy to use. Sparing you all of the details, here are some links. The Bible Analyzer developer anticipates still another new version (4.7) to be released later this month, so keep an eye out. The program is FREE, and operates on Mac, Windows or Linux.
