You should install Anaconda on Mac OS X before you can use Python for data science. The Mac OS X Anaconda installation comes only in one form: 64-bit. Before you can perform the install, you must download a copy of the Mac software from the Continuum Analytics site. The following steps help you install Anaconda 64-bit on a Mac system.
Oct 26, 2014 This video shows the steps to change the default icon for folders in Mac OS X, this will change every folder on the system as well as newly made folders. Mar 03, 2019 1. Install Anaconda On Linux, Windows, MacOS. The anaconda installation is very simple and straight forward. The installation process on all the three platform is very similar. But before that you should download anaconda for your OS platform first. After that follow below steps to install it on different OS platform.
- Locate the downloaded copy of Anaconda on your system.The name of this file varies, but normally it appears as Anaconda-2.1.0-MacOSX-x86_64.pkg. The version number is embedded as part of the filename. In this case, the filename refers to version 2.1.0. If you use some other version, you may experience problems with the source code and need to make adjustments when working with it.
- Double-click the installation file.You see an introduction dialog box.
- Click Continue.The wizard asks whether you want to review the Read Me materials. You can read these materials later. For now, you can safely skip the information.
- Click Continue.The wizard displays a licensing agreement. Be sure to read through the licensing agreement so that you know the terms of usage.
- Click I Agree if you agree to the licensing agreement.The wizard asks you to provide a destination for the installation. The destination controls whether the installation is for an individual user or a group.You may see an error message stating that you can’t install Anaconda on the system. The error message occurs because of a bug in the installer and has nothing to do with your system. To get rid of the error message, choose the Install Only for Me option. You can’t install Anaconda for a group of users on a Mac system.
- Click Continue.The installer displays a dialog box containing options for changing the installation type. Click Change Install Location if you want to modify where Anaconda is installed on your system. Click Customize if you want to modify how the installer works. For example, you can choose not to add Anaconda to your PATH statement. There isn’t a good reason to change the default option unless you have another copy of Python 2.7 installed somewhere else.
- Click Install.You see the installation begin. A progress bar tells you how the installation process is progressing. When the installation is complete, you see a completion dialog box.
- Click Continue.You’re ready to begin using Anaconda.

Tutorials
This tutorial will demonstrate how you can install Anaconda, a powerful package manager, on your Mac.
Anaconda is a package manager, an environment manager, and Python distribution that contains a collection of many open source packages. An installation of Anaconda comes with many packages such as numpy, scikit-learn, scipy, and pandas preinstalled and is also the recommended way to install Jupyter Notebooks. This tutorial will include:
With that, let’s get started
Graphical Installation of Anaconda
Installing Anaconda using a graphical installer is probably the easiest way to install Anaconda.
1 ‒ Go to the Anaconda Website and choose a Python 3.x graphical installer (A) or a Python 2.x graphical installer (B). If you aren’t sure which Python version you want to install, choose Python 3. Do not choose both.
2 - Locate your download and double click it.
3 - Click on Continue
4 - Click on Continue
5 - Note that when you install Anaconda, it modifies your bash profile with either anaconda3 or anaconda2 depending on what Python version you choose. This can important for later. Click on Continue.
6 - Click on Continue to get the License Agreement to appear.
You will need to read and click Agree to the license agreement before clicking on Continue again.
7 - Click on Install
8 - You’ll be prompted to give your password, which is usually the one that you also use to unlock your Mac when you start it up. After you enter your password, click on Install Software.
9 - Click on Continue. You can install Microsoft Visual Studio Code if you like, but it is not required. It is an Integrated Development Environment. You can learn about Python Integrated Development Environments here.
10 - You should get a screen saying the installation has completed. Close the installer and move it to the trash.
Test your Installation
1 - Open a new terminal on your Mac. You can do this by clicking on the Spotlight magnifying glass at the top right of the screen, type “terminal” then click on the terminal icon. Now, type the following command into your terminal
If you had chosen a Python 3 version of Anaconda (like the one in the image above), you will get an output similar to above.
If you had chosen a Python 2 version of Anaconda, you should get a similar output to the one below.
2 - Another good way to test your installation is to try and open a Jupyter Notebook. You can type the command below in your terminal to open a Jupyter Notebook. If the command fails, chances are that Anaconda isn’t in your path. See the next section on Common Issues.
The image below shows a Jupyter Notebook in action. Jupyter notebooks contain both code and rich text elements, such as figures, links, and equations. You can learn more about Jupyter Notebooks here.
Common Issues
The image below shows step 5 of the Graphical Installation of Anaconda from earlier in this tutorial. Notice that when you install Anaconda, it modifies your .bash_profile to put Anaconda in your path.
The problem is that sometimes people have installed multiple different versions of Anaconda and consequently they have multiple versions of Anaconda in their path. For example, say a person needs Python 2 and they install a Python 2 version of Anaconda, That same person then finds that they need Python 3, so they install a Python 3 version of Anaconda. The problem is that you really only need 1 version of Anaconda. A lot of people think that is that if you install a Python 2 version of Anaconda, you are stuck with Python 2. Anaconda is also an environment manager and makes it very easy to go back and forth between Python 2 and 3 on a single installation of Anaconda (learn more here).
Install Anaconda For Mac
To see if you have more than 1 version of anaconda installed and to fix it if you do, let’s first look at your .bash_profile.
1 - Open a new terminal and go to your home directory. You can do this by using the command below.
2 - Use the
cat
command to see the contents of the hidden file .bash_profile. Type the following command into your terminal.You should only see one anaconda version added to your path as you see below, this isn’t a problem for you. Move to the conclusion of the tutorial.
If you see more than one Anaconda version, proceed to step 3.
3 - To remove the old version of Anaconda from your .bash_profile use the command below to edit the file using the nano editor.
From the image above, notice there is a newer Version of Anaconda. Simply remove the older version of Anaconda. Type control + X to exit out of nano.
Save changes by typing Y.
Close that terminal and open a new one. You should be okay now. Keep in mind that this isn’t the only issue you can have when installing Anaconda, but it is a very common issue.
Conclusion
This tutorial provided a quick guide to install Anaconda on Mac as well as dealing with a common installation issue. A graphical install of Anaconda isn’t the only way to install Anaconda as you can Install Anaconda by a Command Line Installer, but it is the easiest. If you aren’t sure what to do after installing Anaconda, here are a few things you can do:
- If you would like to learn more about Anaconda, you can learn about more here.
- If you want to start coding on your local computer, you can check out the the Jupyter Notebook Definitive Guide to learn how to code in Jupyter Notebooks.
- If you want to learn Python, you can check out DataCamp's Intro to Python for Data Science course.
