  • LabVIEW 2017 SP1 for macOS is available only in 64-bit.
  • LabVIEW and LabVIEW Run-Time Engine require 64-bit processors which support SSE2 instructions.

Installation Instructions

Complete the following steps to install and activate LabVIEW for macOS.

Are you installing LabVIEW for the first time? Insert the LabVIEW installation media and follow the onscreen instructions to install LabVIEW. To omit some of these files, click Customize on the Installation Type page.

To install LabVIEW modules and toolkits, refer to the readme of each product for installation instructions. The LabVIEW VI Analyzer Toolkit installs with the LabVIEW Professional Development System for macOS.

You can install NI device drivers from

Are you upgrading from a previous version of LabVIEW? Refer to the LabVIEW Upgrade Notes for information about protecting existing VIs and projects before installing a new version of LabVIEW, as well as upgrade and compatibility issues and a complete list of new features in LabVIEW 2017.

Note  Starting from 2017, LabVIEW supports backward compatibility for the LabVIEW Run-Time Engine. Versions of LabVIEW later than 2017 can load binaries and VIs built with LabVIEW 2017 without recompiling. This improvement applies to stand-alone applications (EXEs), shared libraries (DLLs), and packed project libraries.

Note  If you purchased this product with an NI Software Suite or NI Product Bundle, use the installation media that shipped with your purchase to install this product.

New Features

In LabVIEW 2017 SP1, malleable VIs can adapt to input classes. A malleable VI that calls a method of class A accepts data of unrelated classes as long as the class has a public method with the same name, connector pane pattern, and terminal direction as the method of class A that the malleable VI calls. The malleable VI adapts to the input class by replacing the call to the method of class A with a call to the public method in the input class, if such a method exists.

You can think of this adaptability of a malleable VI as defining an interface of method calls with method name, connector pane pattern, and terminal direction. The malleable VI accepts data of any class that fulfills the interface of method calls, which allows you to use one malleable VI to perform operations on data of unrelated classes or implement multiple interfaces defined by different malleable VIs on one class.

Refer to the labview\examples\Malleable VIs\Class Adaptation\Malleable VIs - Class Adaptation.lvproj for an example of using malleable VIs to define interfaces of method calls.

Supported Modules and Toolkits

LabVIEW 2017 SP1 for macOS supports the following modules and toolkits.

  • Control Design and Simulation Module1
  • MathScript RT Module2
  • VI Analyzer Toolkit

1 The Control Design and Simulation Module does not support the System Identification VIs, System Identification Assistant, and Control Design Assistant.

2 The MathScript RT Module does not support the libraries class of MathScript RT Module functions.

Refer to the readme of each product for more information about system requirements, installation instructions, and activation.
