Octave for macOS

GNU Octave is primarily developed on GNU/Linux and other POSIX conformant systems. GNU Octave for Mac OS X is readily available using package managers such as Fink, MacPorts, and Homebrew.

About version numbers (as of January 2014):

• The 3.8.x are current releases.
• The 3.6.x are previous releases.
• The 3.4.x are very old releases.

Octave server VM installer for OSX 10.10 Yosemite

Instructions and configuration files that cause Vagrant to automatically download and configure an Octave server VM under OS X including 10.10 Yosemite. The install process pulls down the latest stable Linux version of Octave at the time of installation. All software used in running this server VM is open source (Vagrant, VirtualBox, Octave). The Octave server will run headless, and display the Octave GUI and graphics on the host via the Mac's native X-windows server. The recommended configuration ensures that by default user files written by the GUI are in a folder shared with the Mac's filesystem, and the VM suspends automatically when the user quits the GUI. Any edited files then persist in the Mac's shared folder.

Binary installer for OSX 10.9.1

A binary installer for Mavericks can be found on Octave Forge.

This installer will install all binaries for GNU Octave 3.8.0 itself and its dependencies under

 /usr/local/octave/3.8.0 

And will create two entries in the Applications folder

/Applications/Octave-cli.app 
/Applications/Octave-gui.app 

Which will start Octave in CLI and GUI mode respectively, these are just small wrappers containing a startup script and an icon to allow launching Octave from the Finder.

If you wish to uninstall GNU Octave 3.8.0 and all other software installed by this installer you can simply move the three folders listed above to the Trash. Notice that you will need to authenticate with an administrator password to be allowed to do so.

You may need to override Gatekeeper to allow installation. You may find instructions about how to do this on this page in the section labeled "How to open an app from a unidentified developer and exempt it from Gatekeeper".

In short:

• In Finder, Control-click or right click the icon of the app.
• Select Open from the top of contextual menu that appears.
• Click Open in the dialog box. If prompted, enter an administrator name and password.

This installer is known to work on OSX 10.9.1, you may try, at your own risk, to use it for installing on other system versions but it is not guaranteed to work.

Manual Installation from Source

The page Octave for Mac provides minimalistic instructions for building Octave from source on Mac OS X. Additional support for those who need assistance in building Octave is available.

Package Managers

A package manager is a software tool to automate the process of installing, upgrading, configuring, and removing software packages for a computer's operating system in a consistent manner. It typically maintains a database of software dependencies and version information to prevent software mismatches and missing prerequisites. Packages are distributions of software, applications and data. Packages also contain metadata, such as the software's name, description of its purpose, version number, vendor, checksums, and a list of dependencies necessary for the software to run properly. Upon installation, metadata is stored in a local package database. Operating systems based on Linux and other Unix-like systems typically consist of hundreds or even thousands of distinct software packages; in the former case, a package management system is a convenience, in the latter case it becomes essential.

There are three reputable package managers available for Mac OS X. GNU Octave for Mac OS X is readily available using package managers such as Fink, MacPorts, and Homebrew.

The most recent version of Fink's Octave package, MacPorts' Octave port, and Homebrew's Octave formula are generally not the same. Please check the web sites for these package managers to determine if the version of Octave you desire is available.

XCode Dependency

Each package manager requires that XCode be installed. In part this is to provide an initial set of development tools. It *may* be possible to substitute the Mac OS X gcc Installer by Kenneth Reitz, but this alternative has not yet been tested. If any curious/industrious users experiment with using Kenneth's solution over Apple's XCode, please let Octave's developers know of the results. Or, if you prefer, just update the itemized list below. It is recommended that users with XCode already installed avoid installing Kenneth's solution, as it may break your existing XCode installation.

• Fink: The Mac OS X gcc Installer has not been tested.
• MacPorts: The Mac OS X gcc Installer has not been tested.
• Homebrew: The Mac OS X gcc Installer has not been tested.

Fink

The Fink project is an effort to port and package open-source Unix programs to Mac OS X. Fink uses dpkg and APT (Debian's package management system), as well as its own frontend program, fink (which is implemented as a set of Perl modules).

Simple Installation Instructions

• Install XCode via the Mac App Store.
  • Once installed, install the Command Line Tools from XCode's Apple Menu > Preferences > Downloads on 10.7 or 10.8, and use sudo xcode-select --install on 10.9 or 10.10 .
• Follow Fink's installation instructions. For OS X 10.8-10.10, enabling the binary distribution during the initial setup will save you a lot of build time. For those who prefer it, there is a GUI available for Fink, Fink Commander.
• Fink has excellent support for Octave and includes recent as well as dated versions. A list of what Fink has available for Octave is here. To install the latest Octave with GUI support, type fink install octave-qtmac or fink install octave-qtx11 at the Terminal's command line. For those running the 64 bit version of Fink, it is recommended that octave-atlas-qtmac or octave-atlas-qtx11 be installed instead as there are some bugs/features with Apple's vecLib for the X86_64 architecture. Octave has many dependencies which will be downloaded and installed prior to Octave. The entire installation process can take many hours.
• Fink should also be used to install [packages for Octave. For example, the control systems package may be installed by typing fink install control-atlas-oct382 at a terminals command line.

For the doc() function to be supported by Octave, either the unversioned octave, octave-atlas, or octave-ref package must be installed. Essentially, those features used at run-time which don't have a version somewhere in the file path are included in these packages.

MacPorts

MacPorts, formerly called DarwinPorts, is a package management system that simplifies the installation of software on the Mac OS X and Darwin operating systems. It is a free/open source software project to simplify installation of other free/open source software. Similar in aim and function to Fink and the BSDs' ports collections, DarwinPorts was started in 2002 as part of the OpenDarwin project, with the involvement of a number of Apple Inc. employees including Landon Fuller, Kevin Van Vechten, and Jordan Hubbard.

Simple Installation Instructions

• Install "XCode" via the Mac App Store and the "XCode Command Line Tools" as described at MacPorts' installation instructions. If your are running Mac OS X 10.9 (Mavericks) or 10.10 (Yosemite) you just need to type xcode-select --install in the terminal and press the "Install" button of the appearing dialog box.
• If you have MacPorts already installed sooner, update it first by typing sudo port selfupdate and sudo port upgrade outdated in the terminal.
• MacPorts has good support for Octave. A list of what MacPorts has available for Octave is here. To install the most recent version of Octave, type sudo port install octave or if you want the experimental graphic user interface (GUI) sudo port install octave +gui at the Terminal's command line. Octave has many dependencies which will be downloaded and installed prior to Octave. The entire installation process can take a few hours.
• Note that octave-devel has been replaced by octave, see MacPorts Revision 114034.
• The variant installed may be important to the user's experience. The available variants for octave are displayed by typing port variants octave. In MacPorts 2.3.3 the variants atlas, gcc49 and glgui are installed by default (marked with '+' sign in port variants octave output). For the experimental GUI add variant +gui (see above). If you need Java support add the new Java variant (+java).
• Octave depends on arpack. Unfortunately arpack is installed with the accelerate variant by default. The accelerate variant uses Apple's Vector Libraries which have some known bugs that can cause Octave to crash if using certain functions in arpack. To avoid this install arpack with the atlas instead of the accelerate variant sudo port install arpack -accelerate+atlas. You can even do this after you installed Octave. The new variant become active by default.
• If Octave crashes when plotting use the Gnuplot graphic toolkit instead of FLTK. Type graphics_toolkit('gnuplot') in Octave before plotting. For using the nicer wxt-terminal of Gnuplot, type setenv("GNUTERM","wxt") in Octave. To make this the standard behavior append both commands in one of Octave's startup files e.g. your ~/.octaverc.

Homebrew

Homebrew is a package management system that simplifies the installation of software on Mac OS X. It is a free/open source software project to simplify installation of other free/open source software. It is similar in aim and function to MacPorts and Fink. It was written by Max Howell and has gained popularity in the Ruby on Rails community and earned praise for its extensibility.

Simple Installation Instructions

First, install Homebrew:

• Install XCode via the Mac App Store.
  • For Mac OS 10.9 (Mavericks) install the command line tools by xcode-select --install.
  • For earlier versions of Mac OS, install the command line tools from XCode's Apple Menu > Preferences > Downloads.
• Follow Homebrew's installation instructions.
• If running Mountain Lion (Mac OS 10.8) or later, install XQuartz.
• Import the scientific computing packages, including Octave:

brew tap homebrew/science

To install Octave, update to the latest package definitions, install gfortran (Now you don't need to install it manually, it would be installed by dependency), and then Octave:

brew update && brew upgrade
brew install octave

This would install octave with the default dependencies. Note that the default dependencies include java runtime environment. If you do not have java installed, homebrew would guide you to do that. Or you can type brew install octave --without-java to remove its dependency on java.

Note: If brew complains about not having a formula for octave, the following command should fix it:

brew tap --repair

The command below upgrades Octave and its dependencies to the latest Homebrew-supported versions:

brew update && brew upgrade

Octave has many dependencies which will be downloaded and installed prior to Octave. The entire installation process can take a few hours, but precompiled binary packages called 'bottles' are available with default options for Octave and many of its dependencies.

Octave has an experimental built-in GUI (developed using Qt lib) installed by default so that gnuplot and other tools could use it directly. Gnuplot will build with Qt support if Octave's Qt-based GUI is enabled. You do not need to install an X server in most situations. Note: On Snow Leopard, Octave requires an X server. If you install without, Homebrew will guide you to the XQuartz project (https://xquartz.macosforge.org) where you can download this.

You might find that you need to add:

setenv ("GNUTERM", "X11")

to your octaverc file, normally located at /usr/local/share/octave/site/m/startup. See also brew info octave for recommended settings.

In case of trouble, see the Homebrew Troubleshooting Guide, which assists in diagnosing problems and craft useful bug reports. The post by Jatin Ganhotra may also be helpful. Bugs may be reported at Homebrew-science's issue tracker.

Create a launcher app with AppleScript

• Open the "AppleScript Editor" application
• write the following text in the editor window:

tell application "Terminal"
 do script "/path/to/octave; exit"
end tell

or if Octave is in your default path:

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

• Select "Save as ..." from the "File" menu
• 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.

Installing a Mac OS X Bundle

A reliable App bundle for Octave on Mac OS X is not presently available. The developers would like to be able to provide an App bundle, but need volunteers to support the effort. An approach for producing an App Bundle using MacPorts is being documented here. This approach shows promise, but a few problems must be resolved before a bundle will become available.

Octave and many other software packages may be installed and updated using one of the three package managers available for Mac OS X. To install using a package manager, see the section on Package Managers.

Octave-Forge does have App bundles for old Octave, versions and have problems running on Mac OS 10.6 and above. The latest App bundle does not provide full support for the printing, or the documentation features of Octave. Other features may be missing as well. For individuals who'd like to use it anyway please carefully follow the instructions for Installing Mac OS X Bundle.
