== Package Managers ==
'''Install GNU Octave using Homebrew:'''


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.
Follow the [https://brew.sh/ Homebrew installation instructions].


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.
It is advised to install the '''Command Line Tools''' type in the [https://support.apple.com/guide/terminal/welcome/mac Terminal App] before Homebrew:


All package managers below are given in alphabetical order.  The Octave developers do not recommend a certain package manager.
  sudo xcode-select --install


=== Fink ===
A window will pop out to guide the installation.


[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]).
Then, come back to the [https://support.apple.com/guide/terminal/welcome/mac Terminal App] type:


'''Install GNU Octave using Fink:'''
  brew update
  brew upgrade
  brew install octave
 
  octave --gui


*Install Xcode via the Mac App Store.
In case of trouble try <code>brew doctor</code>, see the [https://docs.brew.sh/Troubleshooting Homebrew Troubleshooting Guide].
** 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.
To start the Octave GUI without typing commands in Terminal every time, please create a launcher app with the Script Editor as described below.


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


[https://brew.sh/ 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.
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.


Install GNU Octave using Homebrew:
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:


First, install Homebrew:
do shell script "/usr/local/bin/octave --gui"
*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.
For Apple Silicon based systems, use the following script:


First we ensure brew itself has the latest definitions:
do shell script "/opt/homebrew/bin/octave --gui"
<pre>brew update</pre>


Then, we install Octave
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.
<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:
If you want to start the Octave command-line interface (CLI), enter instead:
<pre>setenv('GNUTERM','qt')
graphics_toolkit("gnuplot")</pre>


Note: If brew complains about:
tell application "Terminal"
<pre>
  do script "/usr/local/bin/octave; exit"
Linking /usr/local/Cellar/ghostscript/9.14...
end tell
Error: Could not symlink share/ghostscript/Resource
/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:
or if Octave is in your default path:
<pre>brew tap --repair</pre>


The command below upgrades Octave and its dependencies to the latest Homebrew-supported versions:
tell application "Terminal"
<pre>brew update && brew upgrade octave</pre>
  do script "`which octave`; exit"
end tell


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.
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"


Octave has a built-in GUI (developed using Qt lib) installed by default so that gnuplot and other tools can use it directly. This GUI is always installed when installing Octave using Homebrew.
To change the application icon:
* Open [[:File:Icon.png|this link]] in a web browser, right-click and select "copy image".
* Select "Octave.app" in the Finder, then press {{Key|command-i}} to bring up the file info dialog.
* In the file info dialog, select the icon (in the top left) and press {{Key|command-v}} to paste the Octave icon over it.

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
