Hi John and Scott-
At this time, NI-DAQmx Base is the only provided driver option for performing data acquisition with NI DAQ cards. NI relies on customer input to track possible opportunities for future software upgrades.
John's feedback has definitely been received, but I would encourage you and anyone else with interest in improvements to Mac OSX support to visit the Product Suggestion Center and voice your suggestions. These requests are handled by our R&D engineers and are the best method to file your suggestions with the decision makers at NI.
Hopefully this helps-
