Yes. You can install DAQmx Base on the Mac. There are some restrictions such as 32-bit operation and limited support for 10.8.
Please give more details about your problem. What version of the OS are you using? Which model of Mac? Which version of DAQmx Base? What kind of DAQ device?
And where are you looking for the device you cannot find? My dog likes to run behind the couch with things, but I did not see your devcie back there.
