[PD] Arduino trouble on Mac

[Pierre-Olivier Boulant]

Hi everyone,

I am working on a expanded hurdy-gurdy for a musician from around here. 
The rotation of the handle controls the speed of a video. It works ok on 
my windows machine, but I can't get it to run on the Mac it's supposed 
to run on eventually.

The Mac is a Power Book Pro running Mac OSX 10.6.8
I installed Pd extended 0.43.4
I installed the brand new Arduino IDE 1.6

I tried with different Arduino boards (Uno and Leonardo) and different 
sketches. In any case [comport] does not receive anything.
In the Arduino IDE the serial monitor works.
Firmata/[Arduino] do not work.
My homebrew protocol doesn't work either.

I don't think it's a matter of selecting the proper COM port. I used the 
same one in the IDE and in Pd extended and just in case I did check the 
other ports too!
The computer has been restarted several times as well.


Is there something I'm missing here?
Are there dependencies I should check?
Is there something to upgrade manually?
Are there some kind of preferences, policies or security settings to tweak?

Thank you very much for you help!

Cheers
Pierre-Olivier
