Last week Logos Bible Software announced the alpha release of the Mac version of their software. It is now available for download at http://www.macbiblesoftware.com/. Because this is an alpha release it's not recommended for downloading to your primary machine, and no support is provided, but for those who just simply can't wait and must be on the bleeding edge of technology, it's now available.
