One of our users had some issues with the installation of the MAC CP210x driver, so I wanted to share the best way to solve this in the event any of you all are experiencing this issue.
(Please note that the arduino installation guide for macOS can be found here)
Download the cp210x driver(links provided below):
Run the file: SiLabsUSBDriverDisk.dmg
Open the terminal for macOS, It should look like the following Icon .
Drag the uninstaller.sh into your terminal, this will prompt your password, and once you are done this will uninstall the driver
Run the Silicon Labs VCP Driver.pkg
Follow the prompts and it should reinstall. Please make sure to restart your computer after completing these steps so that your device registers these changes!
