I don't know if we have any Macintosh hackers out there, but Paul Ossenbruggen has a very, very, very alpha version of Pd running on the Mac OS. It is slow as pond water, lots of features are missing, etc. but you can add two numbers together :-)
I know that Paul hasn't had any time to work on it lately, so if anyone wants to give it a shot, let me know. I'll hook you up with Paul and the source code. Obviously, Pd/GEM should be much easier on Carbon/OS X, so you might just want to skip 8.5...
Later, Mark
