Run the NI-DAQmx for NI myDAQ.dmg file and follow the prompts
Examples and Getting Started
Please note that this driver only supports the NI-DAQmx API, not express VIs like the DAQ Assistant or ELVISmx VIs. We do have unsupported versions of most of the ELVISmx instruments with Mac OS X support in the myDAQ community. For further getting started information & FAQs, see this white paper.
