Note
Using Anaconda in a commercial setting? You may need to use Anaconda Commercial Edition. If you have already purchased Commercial Edition, please proceed to the Authenticating Commercial Edition section after completing your installation here.
Haven’t purchased Commercial Edition yet? Visit https://anaconda.cloud/register to get started.
You can install Anaconda using either the graphical installer (“wizard”) or thecommand line (“manual”) instructions below. If you are unsure, choose the graphical install.
macOS graphical install¶
- Download the graphical macOS installer for your version of Python.
- RECOMMENDED: Verify data integrity with SHA-256.For more information on hashes, see What about cryptographic hash verification?
- Double-click the downloaded file and click continue to start the installation.
- Answer the prompts on the Introduction, Read Me, and License screens.
- Click the Install button to install Anaconda in your ~/opt directory (recommended):
- OR, click the Change Install Location button to install in another location (not recommended).On the Destination Select screen, select Install for me only.NoteIf you get the error message “You cannot install Anaconda in this location,” reselect Install for me only.
- Click the continue button.
- Optional: To install PyCharm for Anaconda, click on the link to https://www.anaconda.com/pycharm.Or to install Anaconda without PyCharm, click the Continue button.
- A successful installation displays the following screen:
- Verify your installation.
Using the command-line install¶
Use this method if you prefer to use a terminal window.
- In your browser, download the command-line version of themacOS installer for your system.
- RECOMMENDED: Verify data integrity with SHA-256.For more information on hash verification, see cryptographic hash validation.
- Open a terminal and run the following:
NoteReplace/path/filename
with your installation’s path and filename. - Install for Python 3.7 or 2.7:
- For Python 3.7 enter the following:
- For Python 2.7, open the Terminal.app or iTerm2 terminal application and then enter the following:
NoteInclude thebash
command regardless of whether or not you are using the Bash shell.NoteReplace~/Downloads
with your actual path andAnaconda3-2020.02-MacOSX-x86_64.sh
with actual name of the file you downloaded. - The installer prompts “In order to continue the installation process, please review the license agreement.”Click Enter to view the license terms.
- Scroll to the bottom of the license terms and enter yes to agree to them.
- The installer prompts you to Press Enter to confirm the location, Press CTRL-C to cancel the installationor specify an alternate installation directory. If you confirm the default location,it will display
PREFIX=/home/<user>/anaconda<2or3>
and continue the installation.NoteUnlike the graphical install, installing the shell file will place it in ~/anaconda<2 or 3> by default,not ~/opt. This is due to limitations with installing .pkg files on macOS Catalina.Installation may take a few minutes to complete.NoteWe recommend you accept the default install location. Do not choose the path as /usr for theAnaconda/Miniconda installation. - The installer prompts “Do you wish the installer to initialize Anaconda3by running conda init?” We recommend “yes”.NoteIf you enter “no”, then conda will not modify your shell scripts at all.In order to initialize after the installation process is done, first run
source<pathtoconda>/bin/activate
and then runcondainit
.NoteIf you are on macOS Catalina, the new default shell is zsh.You will instead need to runsource<pathtoconda>/bin/activate
followed bycondainitzsh
. - The installer displays “Thank you for installing Anaconda!”
- Optional: The installer describes the partnership between Anaconda and JetBrains andprovides a link to install PyCharm for Anaconda athttps://www.anaconda.com/pycharm.
- Close and open your terminal window for the Anaconda installation to take effect.
- To control whether or not each shell session has the base environmentactivated or not, run
condaconfig--setauto_activate_baseFalseorTrue
. To run conda from anywhere without having the base environmentactivated by default, usecondaconfig--setauto_activate_baseFalse
.This only works if you have runcondainit
first.Notecondainit
is available in conda versions 4.6.12 and later. - Verify your installation.
What’s next?¶
Get started programming quickly with Anaconda in the Getting started with Anaconda guide.
Being a software engineer, you often come across many instances where you would require to have Python installed on your Mac.
However, the issue is most modern macOS versions come with rather with Python 2.7.x installed and not the newer, modern version like Python 3.6.5 or Python 3.7.2 (which is the most up-to-date version right now).
This short guide is written to show you how to properly install Python 3 on a Mac OS Xcomputer.
Before you jump into the guide, do take note that there are multiple ways to install Python 3 on a Mac but with this guide, I’ll show you the two easiest ways to do this, step-by-step.
Personally, the way I did it was using a package manager like HomeBrew (it’s okay if you don’t understand what it is). Again, I’ll show you how to do this method down below.
Wait, how do I check if Python 3 is already installed on my Mac?
Simple. Open up your Terminal and type the following line
python --version
and then hit your Enter key:You should see the python version that is currently installed on your Mac.
How to Install Python 3 on macOS: 2 Ways
1. The Simplest Way.
Perhaps the simplest way to install Python 3 on macOS.
This is for you especially if you’re a newbie (though I still strongly recommend you try the HomeBrew method below) or if you don’t want to deal with copy-pasting code into your Terminal and downloading other software.
Here’s how to install Python 3 on your macOS:
- Jump into Python.org downloads page and simply just download the latest Python version.
- Next, run the Python Installer to install Python 3 onto your Mac.
Note
The Python installation may require about 100MB of disk space to install. Once you’ve installed Python 3 you can have it alongside Python 2 without having to delete the latter from your Mac.
- Great! Now once Python 3 is installed, you’ll be able to find it within the Applications directory of your Mac. You’ll also find here a simple IDE called “IDLE.app” which gives you a basic Python IDE.
Help! Where do I find the Applications directory?
Python Mac Os Download
If you can’t find the Applications directory, simply go to Finder by clicking the Finder icon in the Dock (it’s usually the first icon from the left side of the Dock). From there simply, go to the Go menu and select Applications.
Done. If you got yourself lost through the process, you can comment down below.
Next up, I’ll show you how you can install Python 3 using HomeBrew onto your macOS. This is my preferred way and it is just as simple as the method before but it will make your life a whole lot simpler, in the long run, using Python.
2. Install Python 3 on Mac using HomeBrew.
This method is dead-ass simple and a little fun. ?
First of all, you’ll need to have this thing called HomeBrew installed on your Mac. Homebrew is basically a “package manager”. A package manager is an application that helps you install the stuff you need that Apple (or even your Linux System) hadn’t installed in the first place for you.
It’s simple, fast and safe.

Second, you will need to have installed XCode onto your Mac. If you’re thinking of learning how to program or creating iOS apps on your Mac, then it’s good to have XCode installed. We will be using XCode to install HomeBrew application.
Note
If you have already installed XCode onto your Mac you can skip step 1 and jump straight to step 3.
Here are the steps to install XCode, HomeBrew as well as install Python 3 using HomeBrew onto your Mac:
- Jump into your Terminal app on your Mac and run the copy/paste the following command into the Terminal to install XCode onto your Mac:
- Simply click through all the confirmation crap that XCode shows. It may take a little while to install XCode since it is a large program.
- Great! Now that you have XCode installed, you can install HomeBrew! To install HomeBrew, simply copy/paste the following command into your Terminal:

You can confirm the HomeBrew installed correctly by running the command: below:
- You’ve installed HomeBrew! Now let’s install the Python 3, the reason why you’re here. To install the latest version of Python, just copy/paste the following command into your Terminal:
Note
You can confirm which version of Python was installed all by running the command below (the exact same command you tried earlier in this guide). It should show up as follows:
- Finally, let’s run our new Python 3. Simply enter
python3
.
Voila! You have now installed Python 3 successfully if you see something similar in your Terminal:

•If you want to exit, type
exit()
and then hit your Return button on your keyboard. You can also hit both Control and D keys at the same time instead of the Return key.•Remember I mentioned you can run both your new Python 3 alongside your old Python 2? Yup. Simply type
python
into the Terminal to run with Python 2.
