Hi Brian,
I am glad to hear that the work-around of moving the entire .bibledit folder from the old to the new machine works well, and gives you access to all of your data on the new machine.
Still, it is a work-around, and I am left wondering why the backup/restore procedure does not work properly on the Mac, as it does on Linux. If anybody would grant me access, through TeamViewer, to a Mac running OS X 10.x, then I could fiddle around to see what's the problem, and then fix it. I would also be able (hopefully) to look a bit more into the reason why installing bibledit through MacPorts does not work as it should.
The X11 terminal is started like this:
Click the "Applications" icon at the bottom. Scroll down a bit and click "Utilities". Scroll down to the bottom, and click X11.
Teus
