I've set up an Arduino board on both an iMac and an aluminum G4 Powerbook of mine. The Arduino setup seems fine on both... the blinking LED sketch works, yada yada yada.
I'm then trying to use SimpleMessageSystem to interface with Max. This worked fine on the iMac (running the latest version of Max). However, it does not recognize the USB port on my powerbook, although I clicked "print" to check the name of the port (b, in my case).
Is my problem that I am running Max 4.3? Unfortunately, I don't want to switch right now because of 3rd party library issues (Auvi in particular), but does that mean I'm locked out of Max-Arduinoland? It was really easy to set up on the newer computer.
