<p>Also, as of 10/31/2016, there seems to be some strange behavior when trying to use an Atmel Ice programmer from a mac. When you try to program, you may see an error message from usbdev_open() about not claiming the interface. I used the answer posted <ahref='http://www.avrfreaks.net/comment/1421981#comment-1421981'>here (post 32 and 33)</a> -- the attached kext file already has the correct VID and PID. A full restart was required.</p>
