This thread comes up every year or two, try running Pd with JackOSX instead of having Pd communicate directly with OS X. You should see the Pd process decrease it's CPU usage significantly.
My guess is it's a Pd-> PortAudio -> OS X thing.

I get this bug since 2005 on the mac... maybe related to a broad issue in gui<->pd communication?

Pd's idle CPU usage is 15-20%. Does anyone know why this is?
probably a bug.. you could try using gdb and interrupting Pd to see

it is being busy, or some profiling tool (gprof or strace or shark (?) or something else).
Is there anything that can be done to improve the situation?
Try turning DSP on and then off again, maybe.
