There are four main versions of tanach available here. First there is the l’chaim text. This text has mysterious origins and is missing the neviim rishonim. It is also not the masoretic text, but seems to be based on the BHS tanach. It is available in its standard form and in a mac version i made using a utility available in the software archives here. The second text is the chumash from the above text, cleaned up and changed to the masoretic text by dan rice. The third text is the actual BHS text(including neviim rishonim). The fourth text is Steve Gross’s transliterated Tanach. It provides an english transliterated, easily readable version of Tanach.
