GNU Octave is primarily developed on GNU/Linux and other POSIX conformant systems.
For the latest version of GNU Octave there are currently '''no''' installer files (e.g. DMG installer) available.
GNU Octave for macOS is readily available using [http://en.wikipedia.org/wiki/Package_management_system package managers] such as [http://www.finkproject.org/ Fink], [http://www.macports.org/ MacPorts], [https://spack.readthedocs.io/ Spack] and [http://mxcl.github.com/homebrew/ Homebrew]. An unofficial native macOS "Octave.app" distribution of GNU Octave is also available as either [http://octave-app.org/ a dmg or Homebrew cask].


About version numbers (as of December 2018):
However, using the [https://brew.sh/ Homebrew package manager], one can simply install and update Octave on macOS for all latest Apple Silicon architectures (M1 and newer).


*The 4.4.x are current releases.
{{Note|'''GNU Octave {{Release}}''' is the current stable release.}}
*The 4.2.x are previous releases.
*The 4.0.x or earlier are very old releases.


==Installing a macOS App Bundle==
== Homebrew ==
→ ''Link to [https://formulae.brew.sh/formula/octave Octave package] there.''


Good progress has been made on creating a reliable App bundle for Octave on macOS. Approaches using [http://www.macports.org MacPorts] and [http://brew.sh Homebrew] have been considered. The [http://octave-app.org/ Octave.app project] provides an unofficial ready-to-use macOS app bundle installer based on Homebrew.
'''Install GNU Octave using Homebrew:'''

To compile and create the application bundle yourself, see the instructions on [[Create_a_MacOS_X_App_Bundle_Using_Homebrew|how to create the bundle using Homebrew]]. (See instructions on [[Create_a_MacOS_X_App_Bundle_Using_MacPorts|how to create a bundle using Macports]] for reference, but this approach is not currently being used.)
It is advised to install the '''Command Line Tools''' type in the [https://support.apple.com/guide/terminal/welcome/mac Terminal App] before Homebrew:


==Package Managers==
  sudo xcode-select --install


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.
A window will pop out to guide the installation.
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 macOS. GNU Octave for macOS is readily available using [http://en.wikipedia.org/wiki/Package_management_system package managers] such as [http://www.finkproject.org/ Fink], [http://www.macports.org/ MacPorts], and [http://brew.sh/ Homebrew].
Then, come back to the [https://support.apple.com/guide/terminal/welcome/mac Terminal App] type:


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.
  brew update
  brew upgrade
  brew install octave
 
  octave --gui


===Xcode Dependency===
In case of trouble try <code>brew doctor</code>, see the [https://docs.brew.sh/Troubleshooting Homebrew Troubleshooting Guide].


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 [https://github.com/kennethreitz/osx-gcc-installer 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.
To start the Octave GUI without typing commands in Terminal every time, please create a launcher app with the Script Editor as described below.
* Fink: The macOS gcc Installer has not been tested.
* MacPorts: The macOS gcc Installer has not been tested.
* Homebrew: The macOS gcc Installer has not been tested.


===Fink===
== Create a launcher app with the Script Editor ==


[http://www.finkproject.org/ The Fink project] is an effort to port and package open-source Unix programs to macOS. Fink uses [http://en.wikipedia.org/wiki/Dpkg dpkg] and [http://en.wikipedia.org/wiki/Advanced_Packaging_Tool APT] ([http://en.wikipedia.org/wiki/Debian Debian's] package management system), as well as its own frontend program, fink (which is implemented as a set of [http://en.wikipedia.org/wiki/Perl_module Perl modules]).
For example Homebrew installs Octave to {{Path|/usr/local/bin/octave}} (or {{Path|/opt/homebrew/bin/octave}} on Apple Silicon) by default.  From the [https://support.apple.com/guide/terminal/open-or-quit-terminal-apd5265185d-f365-44cb-8b09-71a064a42125/mac Terminal] application you can enter the command <code>which octave</code> to find out the exact location.


====Simple Installation Instructions====
If you know the installation location, open the [https://support.apple.com/guide/script-editor Script Editor] application and write the following text in the editor window if you wish to start the Octave GUI by default:


*Install Xcode via the Mac App Store.
  do shell script "/usr/local/bin/octave --gui"
** Once installed, install the Command Line Tools from Xcode's Apple Menu > Preferences > Downloads on 10.7 or 10.8, and use {{Codeline|<nowiki>sudo xcode-select --install</nowiki>}} on 10.9 or 10.10 .
*Follow [http://www.finkproject.org/download/srcdist.php 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, [http://finkcommander.sourceforge.net 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 [http://pdb.finkproject.org/pdb/browse.php?summary=octave here]. To install the latest Octave with GUI support, type {{Codeline|<nowiki>fink install octave-qtmac</nowiki>}} or {{Codeline|<nowiki>fink install octave-qtx11</nowiki>}} at the Terminal's command line.  For those running the 64 bit version of Fink, it is recommended that {{Codeline|octave-atlas-qtmac}} or {{Codeline|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 [[http://octave.sourceforge.net/packages.php packages] for Octave.  For example, the control systems package  may be installed by typing {{Codeline|fink install control-atlas-oct382}} at a terminals command line.


For the {{Codeline|doc()}} function to be supported by Octave, either the unversioned {{Codeline|octave}}, {{Codeline|octave-atlas}}, or {{Codeline|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.
For Apple Silicon based systems, use the following script:


===MacPorts===
do shell script "/opt/homebrew/bin/octave --gui"


[http://www.macports.org/ MacPorts], formerly called DarwinPorts, is a package management system that simplifies the installation of software on the macOS 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.
Then, in Script Editor, select File>Export. Export As: Octave (or whatever the non-conflicted name you want); File Format: Application (so that it can be run by Finder); Options: Run only; Code sign: Sign to run locally (to avoid annoying asking for permission to access folder each time). Then, you can find and run the GUI application in the Finder.


Following instructions are made for MacPorts 2.3.4 on '''Mac OS X 10.11 (El Capitan)''' and '''GNU Octave 4.0.3''' in the first place:
If you want to start the Octave command-line interface (CLI), enter instead:


====MacPorts Installation====
tell application "Terminal"
You have to install MacPorts prior to the Octave installation anyway.
  do script "/usr/local/bin/octave; exit"
*Install "Xcode" via the Mac App Store and the "Xcode Command Line Tools" as described at [http://guide.macports.org/#installing.xcode MacPorts' installation instructions].
end tell
*Install the appropriate [https://www.macports.org/install.php MacPorts version] for your OS X version. If you had installed Mac Ports in the past already, update it first by typing {{Codeline|sudo port selfupdate}} and {{Codeline|sudo port upgrade outdated}} in the terminal.


====Basic Installation Instructions====
or if Octave is in your default path:
*Now an Octave installation should work with {{Codeline|sudo port install octave}} out-of-the-box but for some reasons the next lines are worth reading.
*If you decide to do the custom Octave installation ignore the point above and go to the next chapter. The custom installation will consume more (compilation) time. The basic installation may work for the most users.


====Custom Installation Instructions====
tell application "Terminal"
For best performance, variability and reliability the custom installation is suggested.
  do script "`which octave`; exit"
end tell


'''Preliminary Port Installations'''
Finally:
*The new Octave 4 port relies on the accelerator variant. Unfortunately this variant is known for some problems (see below). A better alternative is the "atlas" port, it is necessary to build it with the here specified variant prior to the Octave port installation: {{Codeline|sudo port install atlas +gcc5}}. This can last for many hours. Do this overnight. If a prior atlas installation failed, do {{Codeline|sudo port clean atlas}} before reinstallation.
* With the script open in the Script Editor app on your Mac, choose "File > Export".
*Octave depends on arpack, too. 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'' variant instead of the ''accelerate'' variant {{Codeline|sudo port install arpack -accelerate+atlas}}. You can even do this after you installed Octave. The new variant become active by default.
* 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"
 
'''Octave Installation'''
*MacPorts has good support for Octave. A list of what MacPorts has available for Octave is [http://www.macports.org/ports.php?by=name&substr=octave here]. To install the most recent version of Octave, type {{Codeline|sudo port install octave -accelerate+atlas}} 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 some time.
*Note that {{Codeline|octave-devel}} has been replaced by {{Codeline|octave}}, see [https://trac.macports.org/changeset/114034 MacPorts Revision 114034].
*The variant installed may be important to the user's experience.  The available variants for  {{Codeline|octave}} are displayed by typing {{Codeline|port variants octave}}.  In MacPorts 2.3.4 the variants ''accelerate'', ''app'', ''docs'', ''fltk'', ''gfortran'', ''graphicsmagic'', ''qt4gui'' and ''sound'' are installed by default (marked with '+' sign in {{Codeline|port variants octave}} output). If you need Java support add the new Java variant (+java). A installed Java JRE is mandatory. Go To the Oracle [https://www.java.com/ Java website] for Download. The following command works fine: {{Codeline|sudo port install octave -accelerate+atlas+java}}
*<s>If Octave crashes when plotting use the Gnuplot graphic toolkit instead of FLTK. Type {{Codeline|graphics_toolkit('gnuplot')}} in Octave before plotting. For using the nicer wxt-terminal of Gnuplot, type {{Codeline|setenv("GNUTERM","wxt")}} in Octave. To make this the standard behavior append both commands in one of Octave's startup files e.g. your {{Codeline|~/.octaverc}}. To close the graphic window of gnuplot use the Octave command {{Codeline|close()}} to get rid of the Gnuplot instance instead of using the close button of the window.</s>
*The first plot after startuing Octave 4 can last a while.

===Homebrew===
 
Homebrew is a package management system that simplifies the installation of software on macOS. 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.
** Install the command line tools by {{Codeline|xcode-select --install}}.
*Follow [https://brew.sh/ Homebrew's installation instructions].
 
To install Octave, update to the latest package definitions with {{Codeline|brew update}}, and then install Octave.
 
First we ensure brew itself has the latest definitions:
<pre>brew update</pre>
 
Then, we install Octave
<ref>Homebrew has updated some of its scripts. To install Octave as of May 14, 2020, provide the migrated full path by running <code>brew install homebrew/core/octave</code> instead. [Citation needed!]</ref>:
<pre>brew install octave</pre>
 
The default charting package in Octave is straight qt. However, on the Mac gnuplot often works better. To switch to gnuplot, place the following text in your ~/.octaverc file:
<pre>setenv('GNUTERM','qt')
graphics_toolkit("gnuplot")</pre>


Note: If brew complains about:

* Select "Octave.app" in the Finder, then press {{Key|command-i}} to bring up the file info dialog.
Error: Could not symlink share/ghostscript/Resource
* In the file info dialog, select the icon (in the top left) and press {{Key|command-v}} to paste the Octave icon over it.
/usr/local/share/ghostscript is not writable.
</pre>
This is telling you the user permissions for ghostscript are not setup in a way that your user profile can use. You need to change those permissions to your user profile.
The following command will repair the issue:
<pre>
sudo chown -R `whoami` /usr/local/share/ghostscript
brew link --overwrite ghostscript
</pre>
Then run the brew install command again for octave.


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

<pre>brew tap --repair</pre>


The command below upgrades Octave and its dependencies to the latest Homebrew-supported versions:
''Instead of Homebrew, the following package managers can be used to install Octave on macOS:
<pre>brew update && brew upgrade octave</pre>


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.

For the latest version of GNU Octave there are currently no installer files (e.g. DMG installer) available.

However, using the Homebrew package manager, one can simply install and update Octave on macOS for all latest Apple Silicon architectures (M1 and newer).

Info icon.svg
GNU Octave 9.1.0 is the current stable release.

Homebrew[edit]

Link to Octave package there.

Install GNU Octave using Homebrew:

Follow the Homebrew installation instructions.

It is advised to install the Command Line Tools type in the Terminal App before Homebrew:

 sudo xcode-select --install

A window will pop out to guide the installation.

Then, come back to the Terminal App type:

 brew update
 brew upgrade
 brew install octave
 
 octave --gui

In case of trouble try brew doctor, see the Homebrew Troubleshooting Guide.

To start the Octave GUI without typing commands in Terminal every time, please create a launcher app with the Script Editor as described below.

Create a launcher app with the Script Editor[edit]

For example Homebrew installs Octave to /usr/local/bin/octave (or /opt/homebrew/bin/octave on Apple Silicon) 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 if you wish to start the Octave GUI by default:

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

For Apple Silicon based systems, use the following script:

do shell script "/opt/homebrew/bin/octave --gui"

Then, in Script Editor, select File>Export. Export As: Octave (or whatever the non-conflicted name you want); File Format: Application (so that it can be run by Finder); Options: Run only; Code sign: Sign to run locally (to avoid annoying asking for permission to access folder each time). Then, you can find and run the GUI application in the Finder.

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 the 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.

Alternative Package Managers[edit]

Instead of Homebrew, the following package managers can be used to install Octave on macOS:

Anaconda[edit]

Link to Octave package there.

Follow the Anaconda installation instructions.

In the Terminal App type:

 conda create --name octave
 conda activate octave
 conda install -c conda-forge octave
 
 octave --gui

Note that the use of the option --gui shown above is actually unsupported in the context shown (as of 2023 March 31). Expect failure:

 octave: GUI features missing or disabled in this build

Please refer to Octave contributor ngam's response to issue #102 at conda-forge/octave-feedstock. This note is put here to prevent further user frustration. The original author of this wiki page seems to be unaware of this problem and cannot be located to address this discrepant instruction.

MacPorts[edit]

Link to Octave package there.

Follow the MacPorts installation instructions.

In the Terminal App type:

 sudo port selfupdate
 sudo port upgrade outdated
 sudo port install octave
 
 octave --gui
