For the latest version of GNU Octave there are currently '''no''' installer files (e.g. DMG installer) available.
On macOS systems GNU Octave can be installed by:
# macOS App Bundles '''"Octave.app"''' (a single [https://en.wikipedia.org/wiki/Apple_Disk_Image dmg-file])
# macOS [[#Package Managers|package managers]].


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).  
{{Note|'''GNU Octave {{Release}}''' is the current stable release.}}
 
== macOS App Bundles ==
 
The [https://octave-app.org/ Octave.app project] provides an unofficial ready-to-use, drag-and-drop macOS App installer based on [[#Homebrew|Homebrew]] (see below).
* [https://github.com/octave-app/octave-app/releases Download installer from GitHub]
 
A '''very old''' installer is hosted on SourceForge.
* [https://sourceforge.net/projects/octave/files/Octave%20MacOSX%20Binary/2016-07-11-binary-octave-4.0.3/octave_gui_403_appleblas.dmg/download macOS App Bundle of Octave 4.0.3 (with GUI)]  (OS X 10.9+)
 
== Package Managers ==
 
All [https://en.wikipedia.org/wiki/Package_manager package managers] below are given in alphabetical order.  The Octave developers do not recommend a certain package manager.
 
=== Anaconda ===
 
→ ''Link to [https://anaconda.org/conda-forge/octave Octave package] there.''
 
Follow the [https://docs.anaconda.com/anaconda/install/mac-os/ Anaconda installation instructions].
 
In the [https://support.apple.com/guide/terminal/welcome/mac 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 <code>--gui</code> shown above is actually unsupported in the context shown''' (as of 2023 March 31). Expect failure:

== Homebrew ==
Please refer to Octave contributor [https://github.com/conda-forge/octave-feedstock/issues/102#issuecomment-1598020613 ngam's response] to [https://github.com/conda-forge/octave-feedstock/issues/102 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.

It is advised to install the '''Command Line Tools''' type in the [https://support.apple.com/guide/terminal/welcome/mac Terminal App] before Homebrew:
In the [https://support.apple.com/guide/terminal/welcome/mac Terminal App] type:
 
  sudo xcode-select --install
 
A window will pop out to guide the installation.
 
Then, come back to the [https://support.apple.com/guide/terminal/welcome/mac Terminal App] type:


   brew update
   brew update

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

→ ''Link to [https://github.com/macports/macports-ports/blob/master/math/octave/Portfile Octave package] there.''
 
Follow the [https://www.macports.org/install.php MacPorts installation instructions].

To install the '''Command Line Tools''' type in the [https://support.apple.com/guide/terminal/welcome/mac Terminal App]:
 
  sudo xcode-select --install
 
Follow the [https://spack-tutorial.readthedocs.io/en/latest/tutorial_basics.html Spack tutorial] and type in the Terminal App:


== Create a launcher app with the Script Editor ==
  spack install octave
  spack load octave
 
  octave --gui


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.
{{Note|The entire installation process can '''take up to a few hours'''. Octave has many dependencies which will be downloaded and installed prior to Octave.}}


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:
In case of trouble, please visit the [https://github.com/spack/spack/issues Spack repo issues list], and browse through Octave related issues by writing <code>is:issue octave</code> in the filters box.

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.
