I do quite a bit of audio on my Powerbook 800. Its not as good as
linux, but its far from useless. Most of the time, with audio
processing, you actually need to have the realtime mode enabled.
Otherwise the GUI and the audio process have the same priority,
making dropouts much more likely.
There are problems with the realtime flag, but if you are just doing
audio, then it works best with it on on Mac OS X.
The preference is a bit odd. The option is "defeat real-time
scheduling", so for basic audio work, leave it off.

Hi Sciss,
fact of the matter is that the Aqua Tcl/Tk GUI on OSX interferes
with audio processing in an entirely unacceptable way. When I want
to do serious PD audio work, I boot Gentoo PPC Linux. Quite a bit
of optimization for video/3d has been done for the OSX version of
PD,. This was mostly for GEM, as PDP and PiDiP remain quite
unoptimized. But audio doesn't seem to be a specialty/priority for
the developers right now. I base this on comments from James Tittle
and others when I brought this issue up before. I've also gotten
feedback from others on this list that PD+Audio+OSX is on the
border between crippled and useless in its current state.One suggestion which HC Steiner made (IIRC) is to compile PD
against a Fink or DarwinPorts X11 version of Tcl/Tk instead of the
Aqua one. This entails some makefile buggery which I haven't gotten
around to yet.Another suggestion is to make sure that the realtime priority flag
is disabled on OSX with the -nrt flag. This seems to be a
workaround in some cases, but not a solution to the problem.best, d.
