5.1. Setting up your programmer for macOS

If you are using the Pololu USB AVR Programmer, you might need to update the firmware of your programmer to get it working with macOS. See the Firmware Support for Mac OS X section of the Pololu USB AVR Programmer User’s Guide for instructions.

Mac OS X compatibility: we have confirmed that the programmer and Orangutan SVP work on Mac OS X 10.7 and we can assist with advanced technical issues, but most of our tech support staff does not use Macs, so basic support for Mac OS X is limited.

To test your setup, plug the programmer or Orangutan SVP into a USB port on your Mac. Click “Cancel” if you see the following dialog:

In a Terminal window, type ls /dev/tty.usb* and press enter. You should see 1–3 new entries of the form tty.usbmodem<number> (e.g. /dev/tty.usbmodem00022331). These entries represent virtual serial ports created by the programmer or Orangutan SVP.

The entry with the lowest number is the programming port, and later you will need to pass its name as a parameter to AVRDUDE.
