The file format is the same as for the iPad/iPhone. If you have one of those, you can copy directly from them to the Mac. The directory where the files are kept is hidden: Library\Containers\net.e-sword.e-Sword-X\Data\Library\Application Support\
To get there, you must hold Option key down while clicking on the "Go" menu.
My first reaction to this is, I am delighted that there is now a Mac version. My second reaction is; I wish there was a way to close some of the windows and only call them up when needed. The interface seems cluttered. Sometimes in studying, I only need a Bible.
But, it is fast!
Some day I'd love to see connections to DropBox, or some outside cloud system for saving/sharing notes, studies, etc.
Overall, though. Glad to have it. Worth the money. Rick deserves the return for all the work he has put in.
