I don't have a Mac version but according to this BIAB Mac audio recording video from July 2015.
Band-in-a-Box for Mac: Recording Audio

Mac versions have the same capability to edit audio that Windows versions have. That should still be the case if you have a newer version than what is used in the video.

The steps in Windows versions is simple and should be similar, or the same, in your Mac version.
. Realtracks need to be converted to audio - In BIAB mixer, they are not the same.
. Once a RealTrack has been generated from a Chord Chart, save the track as a Performance Track by right clicking on the track and selecting Track Actions\ Save as Performance Track.
. Once the RealTrack has converted to a Performance Track from the Audio Menu select Move Performance Track to the Audio Track.
With this action, the RealTrack will be located and editable on the Audio Track.

After editing, you can reverse the process and move the Audio back to the RealTrack track as a Performance Track and free the Audio Track for further audio processing.
