Mac OS X compatibility: we have confirmed that the programmer works on Mac OS X 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.
Changing the firmware (if necessary)
The standard USB AVR Programmer firmware works with Mac OS X 10.7 (Lion) and later. There is a special, modified version of the firmware that should work on all versions of Mac OS X. To install the modified firmware you will need to use a Windows or Linux computer, but after that all further work can be done on the Mac.
Note: If you have OS X 10.7 (Lion) or later, you don’t need to change your programmer’s firmware. The modified firmware only allows programming of AVRs; it does not support the bonus features of the programmer (the TTL-level serial port and the SLO-scope).
Checking the installation
To check the installation, plug the Pololu USB AVR Programmer into a USB port on your Mac. Click “Cancel” if you see the following dialog:
In a Terminal window, type
If you are using Mac OS X 10.7 or later and have not changed the programmer’s firmware, there should be two new
If you are using an older version of Mac OS X, you will need to install the modified firmware as described above, and you should only see one new
