Dr. Bridges,
I'm no expert on the subject, but I do use both the Mac and Windows versions of e-Sword. I think you will find that all modules here on BibleSupport that are for iPad and iPhone will also work with the e-Sword X for Mac without any changes. Doing a spot check of just a few modules, I see that the College Press Commentaries, Bob Utley Study Guide Commentaries, and Mounce Concise Greek-English Dictionary are among the many modules available both for Windows and Apple versions (which includes the Mac itself) of e-Sword.
Modules ending in .ZIP should be extracted by double-clicking on them once you have downloaded them to the Mac. Modules you download ending in .BBLI, .LEXI, .CMTI, etc. are already ready for installation. Install all these modules by opening e-Sword X, go to FILES, RESOURCES, IMPORT and point the computer to these modules you have downloaded and/or unzipped. This will install them into e-Sword X.
I hope this helps.
