How To Use Python On Mac

To get started you need to download the OSX miniconda installer.
1. Click on the link https: https://repo.continuum.io/miniconda/Miniconda3-4.5.4-MacOSX-x86_64.sh to download the Python 3.6 installer.
2. Wait for it to download. It will place a file called Miniconda3-4.5.4-MacOSX-x86_64.sh in your downloads folder. On my computer using Safari this is ~/Downloads
Open a Terminal window. If you don’t know how to do this click * Applications -> Utilities -> Terminal*
Within the Terminal change directories into the folder where your downloaded file lives, i.e.
Now run the bash “shell” program to install Miniconda

1. Enter y at the Proceed prompt.
2. When the installation completes, close the Terminal window.

Install Spyder IDE and Connect It to Miniconda Python¶

The second half of the installation is the Spyder IDE development environment. This is the software that you use to write, edit and test your Python programs. Spyder IDE calls Python to actually run the program. Spyder is included by default in the Anaconda Python distribution, which comes with everything you need to get started in an all-in-one package.

There is a known issue with version 3.7 of Anaconda Python and certain versions of the Mac OSX operating system. We strongly recommend that you use python 3.6 on OSX to avoid any problems. To install python 3.6, please follow the steps below: To get started you need to download the OSX miniconda installer. Python is a widely-used general-purpose, high-level programming language.

Once the download is finished, type the following command to know the location of Spyder:
It is usually installed in the bin folder within miniconda3
To start Spyder, go to a terminal window and enter

Detecting 64-bits versus 32-bits Mac OS X Systems¶

You are running 64-bit Mac OS X.

Technically, all Apple computers purchased since Q4 2006 have been equipped with 64-bit capable processors. The Mac OS X operating system has supported 64-bit by default since OS X 10.6 Snow Leopard, released in 2009. The upgrade to the latest operating system for your computer is available for free, directly from Apple, since the release of OS X 10.9 Mavericks in 2013.

Python programming language is one of the most used programming language these days. Many Mac and even Windows users are using the programming language for various purposes. The python language has its own IDE to write programs and if you are already coding in python then you must know that python codes are saved in .py format. But many Mac users face the issue of updating python or don’t even know about the latest version of python.

So, if you are one of them and want to update or python or just install the python in your Mac device then follow the methods that I would write in this article.
