Dear Jim Gaede
Thank you for your email. At this moment we have not received any news on a Naza Assistant software for Macintosh. I apologize for the inconvenience.
If you require further assistance you can reach...
I also have a Mac, and dji posted the wrong software, they need to post the Naza-M Assistant software for the Mac. There is no usb connector on the outside of the controller. I had to use a windows computer to turn on course lock and home lock.
