I have downloaded the driver software and it does recognize my 6009 device but there is very little getting started information for the beginner. That brings me back to my original question of has anyone created a vi to generated a 5 VDC 1 Milliamp pulse output signal from a Macintosh ( OSX 10.6.8 Snow Leopard) using LabVIEW 2011 and a NI-6009 USB DAQ device?
