Hi,
I have a perplexing bug on High Sierra. My (official) Leonardo's USB serial port number changes after every upload. I am running the desktop IDE 1.8.5. It makes it difficult to work with and I can't leave the serial monitor open to catch early startup messages that I might want my code to output.
I haven't found anything in Google that looks like it describes my problem. Has anyone else seen it and found a workaround?
Cheers
