To overcome the issue of outdated and/or multiple versions of python, we will use anaconda to install python version 3.x, and to run jupyter notebooks (explained later). Anaconda - Installation MAC. Anaconda installer for macOS. Verify your installer hashes. Install: Miniconda-In your terminal window, run: bash Miniconda3-latest-MacOSX-x8664.sh. Anaconda-Double-click the.pkg file. Follow the prompts on the installer screens. If you are unsure about any setting, accept the defaults. You can change them later. See full list on datacamp.com. Python for Mac OS X Anaconda is a free collection of powerful packages for Python that enables large-scale data management, analysis, and visualization for Business Intelligence, Scientific Analysis, Engineering, Machine Learning, and more. Anaconda describes its Anaconda Distribution as follows: 'The open-source Anaconda Distribution is the easiest way to perform Python/R data science and machine learning on Linux, Windows, and Mac OS X.

Python on a Mac running macOS is in principle very similar to Python onany other Unix platform, but there are a number of additional features such asthe IDE and the Package Manager that are worth pointing out.
5.1. Getting and Installing MacPython¶
macOS since version 10.8 comes with Python 2.7 pre-installed by Apple. If you wish, youare invited to install the most recent version of Python 3 from the Pythonwebsite (https://www.python.org). A current “universal binary” build of Python,which runs natively on the Mac’s new Intel and legacy PPC CPU’s, is availablethere.
What you get after installing is a number of things:
Python3.9folder in your
Applicationsfolder. In hereyou find IDLE, the development environment that is a standard part of officialPython distributions; and PythonLauncher, which handles double-clicking Pythonscripts from the Finder.
/Library/Frameworks/Python.framework, which includes thePython executable and libraries. The installer adds this location to your shellpath. To uninstall MacPython, you can simply remove these three things. Asymlink to the Python executable is placed in /usr/local/bin/.
The Apple-provided build of Python is installed in
/usr/bin/python,respectively. You should never modify or delete these, as they areApple-controlled and are used by Apple- or third-party software. Remember thatif you choose to install a newer Python version from python.org, you will havetwo different but functional Python installations on your computer, so it willbe important that your paths and usages are consistent with what you want to do.
IDLE includes a help menu that allows you to access Python documentation. If youare completely new to Python you should start reading the tutorial introductionin that document.
If you are familiar with Python on other Unix platforms you should read thesection on running Python scripts from the Unix shell.
5.1.1. How to run a Python script¶
Your best way to get started with Python on macOS is through the IDLEintegrated development environment, see section The IDE and use the Help menuwhen the IDE is running.
If you want to run Python scripts from the Terminal window command line or fromthe Finder you first need an editor to create your script. macOS comes with anumber of standard Unix command line editors, vim andemacs among them. If you want a more Mac-like editor,BBEdit or TextWrangler from Bare Bones Software (seehttp://www.barebones.com/products/bbedit/index.html) are good choices, as isTextMate (see https://macromates.com/). Other editors includeGvim (http://macvim-dev.github.io/macvim/) and Aquamacs(http://aquamacs.org/).
To run your script from the Terminal window you must make sure that
/usr/local/bin is in your shell search path.
To run your script from the Finder you have two options:
Drag it to PythonLauncher
Select PythonLauncher as the default application to open yourscript (or any .py script) through the finder Info window and double-click it.PythonLauncher has various preferences to control how your script islaunched. Option-dragging allows you to change these for one invocation, or useits Preferences menu to change things globally.
5.1.2. Running scripts with a GUI¶
With older versions of Python, there is one macOS quirk that you need to beaware of: programs that talk to the Aqua window manager (in other words,anything that has a GUI) need to be run in a special way. Use pythonwinstead of python to start such scripts.
With Python 3.9, you can use either python or pythonw.
Python on macOS honors all standard Unix environment variables such as
PYTHONPATH, but setting these variables for programs started from theFinder is non-standard as the Finder does not read your
.cshrc at startup. You need to create a file
~/.MacOSX/environment.plist. See Apple’s Technical Document QA1067 fordetails.
For more information on installation Python packages in MacPython, see sectionInstalling Additional Python Packages.
5.2. The IDE¶
MacPython ships with the standard IDLE development environment. A goodintroduction to using IDLE can be found athttp://www.hashcollision.org/hkn/python/idle_intro/index.html.
5.3. Installing Additional Python Packages¶
There are several methods to install additional Python packages:
Packages can be installed via the standard Python distutils mode (
Many packages can also be installed via the setuptools extensionor pip wrapper, see https://pip.pypa.io/.
5.4. GUI Programming on the Mac¶
There are several options for building GUI applications on the Mac with Python.
PyObjC is a Python binding to Apple’s Objective-C/Cocoa framework, which isthe foundation of most modern Mac development. Information on PyObjC isavailable from https://pypi.org/project/pyobjc/.
The standard Python GUI toolkit is
tkinter, based on the cross-platformTk toolkit (https://www.tcl.tk). An Aqua-native version of Tk is bundled with OSX by Apple, and the latest version can be downloaded and installed fromhttps://www.activestate.com; it can also be built from source.
wxPython is another popular cross-platform GUI toolkit that runs natively onmacOS. Packages and documentation are available from https://www.wxpython.org.
PyQt is another popular cross-platform GUI toolkit that runs natively onmacOS. More information can be found athttps://riverbankcomputing.com/software/pyqt/intro.
5.5. Distributing Python Applications on the Mac¶
The standard tool for deploying standalone Python applications on the Mac ispy2app. More information on installing and using py2app can be foundat http://undefined.org/python/#py2app.
5.6. Other Resources¶
The MacPython mailing list is an excellent support resource for Python users anddevelopers on the Mac:
Another useful resource is the MacPython wiki:

Mac Os X Uninstall Anaconda
To install Kivy on OS X using
pip, please follow the maininstallation guide.Otherwise, continue to the Kivy.app instructions below.
Following, are additional information linked to from some of the steps in themain installation guide, specific to OS X.
If you’re using Homebrew, you can install Python with:
If you’re using Macports, you can install Python with:
To install frameworks Python on OSX, download it from the mainPython website and follow theinstallation steps. You can read more about the installation in thePython guide.
Source installation Dependencies¶
To install Kivy from source, please follow the installation guide until you reach theKivy install step and then install the additional dependenciesbelow before continuing.
If you’re using Homebrew, you can install the dependencies with:
You will have to manually install gstreamer support if you wish tosupport video playback in your Kivy App. The latest port documents show thefollowing py-gst-python port.
If you’re using MacPorts, you can install the dependencies with:
If you’re installing Python from a framework, you will need to install Kivy’s dependenciesfrom frameworks as well. You can do that with the following commands (customize as needed):
Now that you have all the dependencies for kivy, you need to make sureyou have the command line tools installed:
Using The Kivy.app¶
Kivy.app is built on the current GitHub Action macOS version and will typicallynot work on older OS X versions. For older OS X versions, you need to build Kivy.appon the oldest machine you wish to support. See below.
For OS X 10.14.4+ and later, we provide a Kivy DMG with all dependenciesbundled in a virtual environment, including a Python interpreter. This isprimarily useful for packaging Kivy applications.
You can find complete instructions to build and package apps with Kivy.app in the readmeof the kivy-sdk-packager repo.
To install the Kivy virtualenv, you must:
Navigate to the latest Kivy release on Kivy’s website orGitHub and download
Kivy.dmg.You can also download a nightly snapshot ofKivy.app.
Open the dmg
In the GUI copy the Kivy.app to /Applications by dragging the folder icon to the right.
Optionally create a symlink by running the following command:
This creates the
kivybinary that you can use instead of python to run scripts.I.e. instead of doing
kivy-mpipinstall<modulename>to run it using the kivybundled Python interpreter with the kivy environment.
As opposed to activating the virtualenv below, running with
kivywill use the virtualenvbut also properly configure the script environment required to run a Kivy app (i.e. settingkivy’s home path etc.).
Using the App Virtual environment¶
Mac Os X Download For Windows
The path to the underlying virtualenv is
/Applications/Kivy.app/Contents/Resources/venv.To activate it so you can use python, like any normal virtualenv, do:
On the default mac (zsh) shell you must be in the bin directory containing
activate to beable to
activate the virtualenv, hence why we changed the directory temporarily.
kivy_activate sets up the environment to be able to run Kivy, by setting the kivy home,gstreamer, and other variables.
Install Anaconda Mac Os X
Start any Kivy Application¶
You can run any Kivy application by simply dragging the application’s main fileonto the Kivy.app icon.
