Take a look at http://jackaudio.org/download.

I'm a Non-Mac-but-PC-Linux-user. For Linux the command will be similar 
to this:
jackd -Rdalsa -dhw:0 -r$sample_rate -p$frames_period -n2 -Xseq

Important is:

-d hw:[number of the audio device]

For example, a PC on-board audio device might have the "name" "hw:1" and 
a more professional PCI card might have the "name" "hw:0". I guess there 
will be no -d alsa for MacOS, I might be wrong. You need to set up 
$sample_rate and $frames_period to your needs.

I don't know if your Mac supports a tickless timer, try "--clocksource 
h" to use a high resolution timer.

On My PC there's a problem with JACK1, JACK1 is able to disconnect 
clients and because of some unknown incompatibility JACK1 randomly 
disconnect clients. JACK2 never disconnect clients, so I'm using JACK2 
and everything is ok here. Dunno, there might be some advantages by JACK1.

Perhaps some Mac users could help you to set up JACK.
