this is benign, if you then do:

it should work... doesn't sound like an OSX problem then

yes, I think once the audio system has started calling the function has no
effect.

so - the question is whether the audio is working at all... try running
examples/02-bars.scm after calling start-audio.

and to print out the values, try something like:

(define (render)
    (display (gh 0))(newline))

(every-frame (render))

another thing, do the buffer size and samplerate setting match jacks?

cheers,
