Serial communication between Arduino and Apple M1 running Ventura

I am following along with this tutorial to get an Arduino communicating with Max MSP via serial. The same patch and sketch combo works on my 2014 Macbook running Big Sur and my Windows 10 machine, but not my Macbook M1 running Ventura.

My first thought was that perhaps it had to do with the lightning ports, but I'm able to read the Arduino's serial output on Ventura in the Arduino IDE, just not in Max. So I'm wondering if this is a software compatibility issue between Max and Ventura? Has anyone encountered this or have any insight that might clue me into what's blocking this communication?

Could it be an issue of permissions? I think I remember a student of mine had a similar problem a few years ago. But I can’t remember how we solved it anymore, unfortunately.

Another aspect I could think about are conflicting FTDI drivers. did you instal third party divers at one point?

Hi Jan,

Thanks for your reply. I don't think I've installed any other drivers, but if it was a driver conflict or an issue of permissions, wouldn't either scenario also interfere with the Arduino IDE's ability to read serial data? It's being read into the IDE okay but not Max.
