I'm not aware of any specifically made for OSX. I was thinking of writing one, actually, but have been too busy with other projects.
That would be just great!
I really miss a usable native Mac OS X ABX application.

This might be a good place to hash out specs if anyone is interested.
Let me be the first to post some wanted features:
* Lossy audio support (ex. MP3, Ogg Vorbis, AAC and Musepack)
* Lossless audio support (ex. Apple Lossless, WavPack, FLAC, Ogg FLAC, Monkey's Audio, AIFF and WAVE).
* Gain correction.
* Offset correction.
* Select playback range.
* Save, and open, sessions.
