Reasons To Install Python on Mac

<img alt="Reasons-and-Relevance-To-Install-Python-on-Mac-1" data- data-src="https://kirelos.com/wp-content/uploads/2023/10/echo/Reasons-and-Relevance-To-Install-Python-on-Mac-1.png" data- decoding="async" height="486" src="data:image/svg xml,” width=”817″>

The primary reason to use macOS and Python for programming is extreme security that no other operating system except Linux can provide. Hackers and spammers around the world develop malware and virus programs for Windows PCs because the majority of computer users use Windows. 

Since macOS has a smaller market share, hackers rarely target MacBooks and iMacs. Also, Apple has a robust security team that leaves no stone unturned to make macOS virtually immune to malware and viruses.

Other major reasons are as follows:

  • MacBooks and iMacs have been specifically known for creative, scientific, and computer programming works.
  • macOS is Unix-based, providing a robust command-line interface for development and scripting.
  • Mac comes with a suite of developer tools like Xcode, Terminal, and Homebrew.
  • Macs are known for their high-quality hardware, ensuring a smooth and reliable development experience.
  • The intuitive macOS interface is conducive to productivity, with an efficient window management system.
  • If you’re into iOS app development, Mac is essential due to its compatibility with Xcode.
  • Macs tend to have a longer lifespan and are known for their reliability, reducing downtime.  

Do Macs Come With Python for Mac Pre-Installed?

macOS uses Python scripting for some of its tasks and modules in the backend. Hence, until macOS 12.3, it would ship all MacBooks and iMacs with pre-installed Python 2.7 framework.

However, developers have stopped using Python 2.X editions because the Python Software Foundation is no longer supporting this Python build.

So, Apple announced in 2019 in a macOS Catalina 10.15 release note that it’ll stop shipping MacBooks and iMacs with preinstalled Python 2.7. However, Apple delayed the process and finally did it for macOS Monetery 12.3 releases. 

So, if you’re using a dated Mac before macOS 12.3, you should have Python 2.7 preinstalled on your system. The newer Macs, like Ventura and Sonoma, no longer come with any build versions of Python. 

If you need Python 3.X edition for functional programming, you must install it yourself by following any of the methods mentioned in the below sections.

How To Install Python on Mac

There are various ways to set up Python on Mac. Find below all the effortless and popular ways:

Update the Existing Version of Python for Mac

If you’re using macOS 12.3 or earlier versions, your MacBook or iMac already has a Python distribution. You just need to update or upgrade it to the latest Python build so you can develop awesome programs. Find below the steps:

Check Python Version

  1. Launch the Terminal app by looking it up on Spotlight.
  2. Type the following code in Terminal and hit Return:
python --version
  1. The Terminal should show a version of the Python distribution like 2.7.
<img alt="Check Python Version" data- data-src="https://kirelos.com/wp-content/uploads/2023/10/echo/Check-Python-Version.png" data- decoding="async" height="496" src="data:image/svg xml,” width=”942″>

Since I’m using macOS Ventura to write this guide, my system is unable to show any Python distribution version because it doesn’t have any. But, macOS systems older than 12.3 will show a Python version.

Install Homebrew

After knowing your Python version, follow these steps to update or upgrade it using Homebrew:

  1. Copy and paste this command into the Terminal app:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  1. Hit Return to execute.
<img alt="Install homebrew" data- data-src="https://kirelos.com/wp-content/uploads/2023/10/echo/Install-homebrew-968×630.png" data- decoding="async" height="630" src="data:image/svg xml,” width=”968″>
  1. Enter the system password to authenticate the action.
  2. Now, the Terminal will go through various stages to download the distributions it needs.
<img alt="Return to start download" data- data-src="https://kirelos.com/wp-content/uploads/2023/10/echo/Return-to-start-download-972×630.png" data- decoding="async" height="630" src="data:image/svg xml,” width=”972″>
  1. Wait until you see the “Installation Successful” message.
<img alt="Homebrew install complete" data- data-src="https://kirelos.com/wp-content/uploads/2023/10/echo/Homebrew-install-complete-968×630.png" data- decoding="async" height="630" src="data:image/svg xml,” width=”968″>
  1. Now, copy and paste the following script and hit Return to install Brew to Path:
echo 'eval "$(/opt/homebrew/bin/brew shellenv)’ >> 
/Users/tamaldas/.zprofile eval $(/opt/homebrew/bin/brew shellenv)
  1. The above script is generated at the end of the Homebrew installation on the Terminal so you can copy it from there or edit the username in this /Users/tamaldas/.zprofile code element before using the code.

Update or Upgrade Python Distribution

Now that you have Homebrew in your MacBook or iMac follow these steps to update or upgrade Python:

  1. Go to the same Terminal console.
  2. Copy and paste this code into it:
brew upgrade python
  1. This will start updating the existing Python installation after authorizing the action with a password.
<img alt="Brew update python" data- data-src="https://kirelos.com/wp-content/uploads/2023/10/echo/Brew-update-python-975×630.png" data- decoding="async" height="630" src="data:image/svg xml,” width=”975″>

The code will work just fine on an older Mac that has the Python 2.7 framework. Since I’m using the latest Mac, Python isn’t available, and hence the Terminal shows this message, “zsh:command not found.”

Once the process is over, reboot the Mac to enjoy the latest Python distribution when coding.
