in devel, it shouldn't be a big difference if you're running pd with the changed scheduler, that's computing dsp in the audio driver thread.
Can anyone currently using PD for low latency audio on OSX follow up on this?
I'd like to know if anyone has done any "speed tests" between Linux with ALSA and with JACK compared to OSX with Portaudio and with JACK. How much latency should I expect to lose from my HDSP, for example, if I run the same patches I normally use under Linux/JACK on OSX/Portaudio or OSX/JACK?
Also if anyone has had difficulty/success compiling PD with JACK support on OSX, either Main or Devel branch.
[Yes, BTW, I am thinking of getting a new computer! ;-) ]
thx, derek
BUMP!
OK, since nobody bit the last one... a simpler question: what would be the best way to go to use PD with Jack on OSX? Compile Miller's, compile Devel or use one of the installers (and if so which?)

You can use the nice GUI program found at http://www.jackosx.com/ perfect for n00bs and others.

The only catch is that it only works with Pd version 0.37 (That runs in Terminal + Wish!) or as one user put it "an older version". Thus I have been using 0.39 devel and 0.37 concurrently specifically for this reason you mention. The Digidesign hardware doesn't work for some reason with the new versions of Pd?? It shows up but there is no output. Maybe it was a change in the CoreAudio driver or something.
Although in reference to the CoreAudio driver, I've had a little success with the method of first launch the manager (Digi CoreAudio Manager), change settings then launch clients. It seems for some reason settings are disabled once a client is connected (??)

i don't think so. look here: http://at.or.at/hans/pd/installers.html Pd-0.39test2-extended-RC0.app Test Version
runs nicely.

Thx. I had Jack covered already!
http://at.or.at/hans/pd/installers.html Pd-0.39test2-extended-RC0.app Test Version
This is the one I tried just now. Thanks.
best, derek

If by nicely you mean it has trouble saving Preferences ...
it outputs to jack at least though.
