Some users execute Audacity from the DMG. This works better now in
HEAD, because Save and Export open to Documents, and all-in-one means
that we don't lose Nyquist effects (assuming 1567 doesn't strike). So
the FAQ about it doesn't apply.
For some reason this doesn't work in jc10. Audacity just bounces in
the Dock and quits. Perhaps jc11 won't.
