No matter your reason, installing Python on your Mac will give you access to a powerful and versatile programming language that can help you achieve your goals.
Installing Python on a Mac
Step 1: Check Your Mac’s Operating System
Before you begin the installation process, it’s important to check your Mac’s operating system (OS). Python is compatible with most versions of Mac OS X, but some older versions may not support the latest version of Python.
To check your Mac’s OS, click on the Apple icon in the top left corner of your screen and select “About This Mac”. The version of your OS will be displayed under the “Overview” tab.
Step 2: Download the Python Installer
To install Python on your Mac, you will need to download the Python installer from the official Python website. Go to https://www.python.org/downloads/ and click on the “Download Python” button.
You will see a list of available versions of Python. If you are new to Python, it is recommended to download the latest version (currently Python 3.9.6). However, if you need to use Python 2.7 for a specific project, you can download that version as well.
Step 3: Run the Installer
Once the installer has finished downloading, double-click on the downloaded file to run it. A pop-up window will appear asking you to confirm the installation. Click “Install” to proceed.
Step 4: Customize the Installation (Optional)
The installer will give you the option to customize your installation. If you are new to Python, it is recommended to leave the default settings as they are. However, if you are an experienced Python user, you can choose to customize your installation by selecting the components you want to install.
Step 5: Complete the Installation
Once you have selected your installation options, click “Install” to begin the installation process. The installer will take a few minutes to complete the installation. Once it’s finished, you will see a pop-up window confirming that Python has been successfully installed on your Mac.
Step 6: Verify the Installation
To make sure that Python has been installed correctly, open the Terminal application on your Mac. Type “python –version” and press enter. If Python has been installed correctly, you will see the version number displayed in the Terminal.
Installing Python 2.7 on a Mac
If you need to use Python 2.7 for a specific project, you can follow the same steps outlined above to install it on your Mac. However, there are a few additional steps you need to take to ensure that Python 2.7 is set as the default version on your Mac.
Step 1: Download the Python 2.7 Installer
To install Python 2.7 on your Mac, you will need to download the installer from the official Python website. Go to https://www.python.org/downloads/ and scroll down to the “Looking for a specific release?” section. Click on the “Python 2.7” link to download the installer.
Step 2: Run the Installer
Once the installer has finished downloading, double-click on the downloaded file to run it. A pop-up window will appear asking you to confirm the installation. Click “Install” to proceed.
Step 3: Customize the Installation (Optional)
The installer will give you the option to customize your installation. If you are new to Python, it is recommended to leave the default settings as they are. However, if you are an experienced Python user, you can choose to customize your installation by selecting the components you want to install.
Step 4: Set Python 2.7 as the Default Version
Once the installation is complete, you will need to set Python 2.7 as the default version on your Mac. To do this, open the Terminal application and type the following command:
defaults write com.apple.versioner.python Version 2.7
This will set Python 2.7 as the default version on your Mac.
