On macOS systems GNU Octave can be installed by:

A very old installer is hosted on SourceForge.

In case of trouble, please visit the Spack repo issues list, and browse through Octave related issues by writing is:issue octave in the filters box.

Create a launcher app with the Script Editor

For example Homebrew installs Octave to /usr/local/bin/octave by default. From the Terminal application you can enter the command which octave to find out the exact location.

If you know the installation location, open the Script Editor application and write the following text in the editor window:

do shell script "/usr/local/bin/octave --gui"

if you wish to start the Octave GUI by default. If you want to start the Octave command-line interface (CLI), enter instead:

tell application "Terminal"
 do script "/usr/local/bin/octave; exit"
end tell

or if Octave is in your default path:

tell application "Terminal"
 do script "`which octave`; exit"
end tell

Finally:

• With a script open in the Script Editor app on your Mac, choose "File > Export".
• In the menu that appears, select "Application" from the "File format" menu, then navigate to the "Applications" folder and save your script there as "Octave.app"

To change the application icon:

• Open this link in a web browser, right-click and select "copy image".
• Select "Octave.app" in the Finder, then press command-i to bring up the file info dialog.
• In the file info dialog, select the icon (in the top left) and press command-v to paste the Octave icon over it.
