Scilab for macOS

Scilab is an Open source software for numerical computations developed by the Scilab Team at ESI and by industry and academic contributors.

This page aims to bring macOS builds of Scilab 6.0.2 and 6.1 (builds for Linux, Windows and general information can be found on Ressources for preparing and making available this specific macOS build of Scilab are provided by the University of Technology of Compiègne (UTC).


The macOS build is distributed under the same license as Scilab, i.e. GPL v2.


Version of macOS

Scilab builds available on this page run on macOS High Sierra, Mojave, Catalina and Big Sur, supporting Intel and newer M1 machines. See the eventual details of installation in the « Files » and « Troubleshooting » section.


Scilab needs a Java Virtual Machine to be run in GUI mode. If you don't have particular needs for a given version, let Scilab download and install the JDK by itself when it is launched for the first time (it will be downloaded from

If you already installed another JDK (e.g. Of Oracle or Apple brand), depending on the version of macOS Scilab may fail to start and ask you to install a Java Runtime Environment. To enable your actual JDK to run Scilab, please download the archive enableJDK.dmg which contains a small AppleScript application doing the job for you (administrator priviledges will be required).

Problems with macOS Catalina or Big Sur

macOS Catalina introduced new security controls. For example, apps are now required to ask your permission before accessing parts of the drive where documents and personal files are kept. If Scilab does not show files in the FileBrowser component, you will have to enable the command-line interpreter /bin/sh (which is run just after you double-click on Scilab's icon) in the "Privacy" tab in the System Preferences Control Panel. This small video shows how to find the /bin folder by using the keys combination Command-Shift-G and then drag and drop /bin/sh in the list of authorized applications.

Problems with Mac M1 machines

Newer Mac M1 machines need the Rosetta 2 binary dynamic translator to execute applications compiled for Intel architecture. If you never run such an application on your Mac M1 it will complain when trying to launch Scilab for the first time, with the message: You don't have the permission to open the application "Scilab". To solve this you need to install Rosetta from the command line. Locate and lauch the "Terminal" application, then type the following on the command line :

softwareupdate --install-rosetta --agree-to-license

Then relaunch Scilab from its icon, and continue the installation.
