I have a brand new argon plugged into my Mac running 10.14. particle serial waits indefinitely looking for a serial device. It looks like these devices are supposed to be named /dev/tty.usbmodem*, but no relevant device is showing up on my Mac. The argon shows up in lsusb (installed via homebrew).
$ particle serial monitor --follow Polling for available serial device... ^C $ ls /dev/tty.usb* ls: /dev/tty.usb*: No such file or directory $ lsusb ... Bus 020 Device 000: ID 2b04:c00c 2b04 Argon CDC Mode Serial: e00fce686234def07e33c022
Is there another package or driver I need to install?
