You have to boot MacOS first and then run the Booter. There was some recent discussion about this and there are mulitple problems to be solved before MacOS-less booting will work. You can set the machine up to boot NetBSD automatically when MacOS boots, I believe. You set the Booter to boot when launched and then put it in the Startup items folder.
