We’ve already updated the instructions for firmware update to use command line directly, without any need for an updater program any more. More specifically, for OS 3.x, the firmware update is OTA anyways, so no need to use any software. For OS 2.3, we’ve updated the instructions to use avrdude program directly. This will save us a lot of time of having to update the updater program since OSX update tends to break legacy programs. You can delete the updater program as it’s not needed any more.
