No, unfortunately no driver has been developed for the GPIB-SCSI-A to run on Mac OSX. However, there is a OSX driver for the GPIB-ENET/100. This is an ethernet to GPIB controller. If you have an ethernet connection on your computer, this may be an effective way to communicate with your mass spectrometer. Here is a link to a page with more information about the GPIB-ENET/100: http://sine.ni.com/apps/we/nioc.vp?cid=4409〈=US
