Is a driver needed for the Pimoroni Pico Plus 2 on macOS?

I’m trying to program the Pimoroni Pico Plus 2 from the Arduino 2 IDE using Earle Philhower’s Arduino Pico library. However, I’m getting a connection error from the Arduino IDE so am wondering if I am maybe missing a driver. Is there a driver that is recommended for macOS?

thanks!
