Installed Files and Paths
There are three main locations where NI-VISA installs files.
The local /Library/Frameworks folder contains the VISA.framework folder. This folder contains all needed headers and supporting Passport libraries that NI-VISA uses.
In the local /Applications/National Instruments folder, there is an NI-VISA folder. This folder includes the NI-VISA Help, as well as several groups of C examples using NI-VISA. This NI-VISA folder also includes a graphical utility called NI-VISA Configuration to configure VISA options and the VISA Interactive Control (VISAIC).
Finally, the /Library/Preferences folder contains an NIvisa folder with .ini files. These files are used for NI-VISA settings and status codes.
