In the past I couldn’t afford any of the above, so I settled on using free software from first http://onlinebible.net/ which used to have a version for Macintosh OS 9 and earlier (at that time better than their Windows™ version) with their final Mac version for OS X on PowerPC, a little bit buggy but has some features not found in other software (I still have it on an old PowerPC Mac). One feature I use was the ability to make its display font one from a pre-Babylonian-exile Hebrew font where it’s impossible to add the Masoretic points. On newer computers I have software from http://www.crosswire.org with the Hebrew text being the Aleppo unpointed (doesn’t even make a distinction between the Sin and Shin) text. I’ve installed it on Mac, Linux and Windows™.
There may be other packages as well, but these are the ones I know of for studying Biblical Hebrew.
