BWGEN is Windows only but there are some that work with the Mac. Check out:
http://gnaural.sourceforge.net/ --- Open source
http://uazu.net/sbagen/ ---- Open source
Both of these work with Mac OS.
On another note though, Binaural Beats aren't exactly rocket science that requires an application to create. Binaural beats consist of a carrier tone and a second tone that differs from the carrier by the number of cycles you want to entrain to. If you want to entrain to 8 Hz, just generate a tone of say 150 Hz on the left channel and 158 Hz on the right channel. Put on your headphones and hit the play button. ANY audio editor like Audacity (http://audacity.sourceforge.net/)( also runs on Mac) can do this. Changing the entrainment frequency is accomplished by changing the second tone at the appropriate time.
Hope this helps.
