I have installed osx High Sierra on a new (but old) Mac. To my surprise I can not connect to the usb serial port.
comport $1 57600 ... couldn't create [arduino]: version 0.6beta
I recall not doing anything else than installing Arduino and then all I needed in Vanilla was [arduino] and [arduino-help] in the project folder. On Linux I had to install a serial driver.
So far I have tried:
Putting all files from the Master in the project folder.
Installing Pdunio from Deken.
PurrData and Pd extended recognize the port and works.
What am I missing?
