7 Essential Steps: How to Install PowerShell on Mac for Advanced Users
As an expert software engineer, I am often asked about my preferred command-line tools. While there are many powerful and versatile options out there, one tool that continues to stand out is PowerShell. Microsoft’s PowerShell has come a long way and is now an indispensable asset for IT professionals around the globe.
In recent years, Microsoft made an exciting move by making PowerShell available for macOS. This development opened up possibilities for Mac users to take advantage of PowerShell’s robust capabilities. In this comprehensive article, I will guide you through the seven essential steps to install PowerShell on your Mac with ease.
*Step 1: Prerequisites and Preparation*
Before diving in, we need to ensure that your Mac meets the minimum system requirements. For a successful installation, your Mac must have macOS 10.12 or later. You will also require the Homebrew package manager. If you haven’t installed Homebrew yet, you can do it by executing the following command in your Terminal:
“`
/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)”
“`
*Step 2: Update Homebrew*
It’s always a good practice to keep your package manager updated. Run the following command to update Homebrew and its formulae:
“`
brew update
“`
*Step 3: Install PowerShell (pwsh)*
Now that your Homebrew package manager is up to date, enter the following command in the Terminal to initiate the PowerShell installation:
“`
brew install –cask powershell
“`
The installation process may take a few minutes, as Homebrew downloads the necessary files and sets up PowerShell on your Mac.
*Step 4: Verify Installation*
Once PowerShell has been installed, you should now be able to access it from your command line. To verify that the installation was successful, open a new Terminal window and execute the following command:
“`
pwsh
“`
If everything went smoothly, you will see a new command prompt that resembles the following:
“`
PowerShell 7.1.3
Copyright (c) Microsoft Corporation.
https://aka.ms/powershell
Type ‘help’ to get help.
PS /Users/yourusername>
“`
Congratulations, you now have PowerShell running on your Mac!
*Step 5: Familiarize Yourself with PowerShell Commands*
Now that PowerShell is up and running on your system, it’s time to familiarize yourself with some essential commands. The following are a few examples of frequently used commands in PowerShell:
– `Get-Command`: This command retrieves a list of all available PowerShell cmdlets, functions, and scripts.
– `Get-Help`: Provides complete details about a specific command, including its syntax and usage examples.
– `Set-ExecutionPolicy`: Sets the default execution policy for PowerShell sessions, which determines the level of trust for running scripts.
*Step 6: Customize Your PowerShell Environment*
Advanced users often prefer to personalize their command-line environment to match their workflow. You can customize your PowerShell experience by modifying the PowerShell profile. The profile is a PowerShell script that runs when you start a new session, allowing you to define aliases, functions, and other settings.
To edit your profile, enter the following command in your PowerShell session:
“`
notepad $PROFILE
“`
This will open your profile in a text editor, where you can add any customizations you desire. Save the changes and restart your PowerShell session to apply the new settings.
*Step 7: Learn More About PowerShell on Mac*
There is an extensive array of resources available to learn more about using PowerShell on macOS. The official [PowerShell GitHub repository](https://github.com/powershell/powershell) provides detailed documentation, guides, and examples to help you expand your knowledge.
Now that you know how to install PowerShell on Mac, you are ready to unlock the true potential of this powerful command-line tool. By following these seven essential steps, you’ve gained an edge in the world of software engineering and command-line mastery. Happy scripting!

How can I execute PowerShell on a Mac?
To execute PowerShell on a Mac in the context of the PowerShell command-line, you need to complete the following steps:
1. Install PowerShell: First, you need to install PowerShell on your Mac. You can do this using Homebrew, a package manager for macOS. If you don’t have Homebrew installed, you can install it by following the instructions on their website: https://brew.sh/
2. With Homebrew installed, open the Terminal app and run the following command to install PowerShell:
“`
brew install –cask powershell
“`
3. Launch PowerShell: After the installation is complete, you can launch PowerShell by typing the following command into the Terminal:
“`
pwsh
“`
This will start the PowerShell command-line environment, and you should see the PowerShell prompt, similar to this:
“`
PowerShell 7.1.3
Copyright (c) Microsoft Corporation.
All rights reserved.
https://aka.ms/powershell
Type ‘help’ to get help.
PS /Users/yourusername>
“`

“`
To exit PowerShell, simply type `exit` and press Enter.
Remember that PowerShell syntax and cmdlets are different from traditional Bash commands on macOS. Make sure you are using the correct commands while working within the PowerShell environment.
Is PowerShell identical on Mac and Windows?
PowerShell on Mac and Windows is not entirely identical, but they are very similar. With the introduction of PowerShell Core, a cross-platform version of PowerShell, most of the functionality is now available on both platforms.
However, there are some differences due to the underlying operating systems. For example, some cmdlets and modules might not work on Mac as they rely on Windows-specific technologies like Windows Management Instrumentation (WMI) or Component Object Model (COM) objects.
In summary, while PowerShell Core has brought a significant level of cross-platform compatibility to PowerShell, there still exist platform-specific differences between Mac and Windows environments.

What are the top tips and tricks for troubleshooting PowerShell installation issues on macOS?
When installing PowerShell on macOS, you might encounter some issues that prevent it from being installed or functioning correctly. Here are the top tips and tricks for troubleshooting PowerShell installation issues on macOS:
1. Verify System Requirements: Before you begin installing PowerShell, make sure your macOS meets the minimum system requirements. PowerShell requires macOS 10.12 or later, and that OpenSSL is installed on your system.
2. Use Official Installation Methods: To avoid potential issues, always use the official installation methods listed in PowerShell’s GitHub page, such as using Homebrew or direct download of the .pkg file. Avoid unofficial distribution sources.
3. Update Homebrew: If you’re using Homebrew to install PowerShell, make sure Homebrew itself is up-to-date by executing `brew update` before installing or updating PowerShell.
4. Check for Other Versions: If the installation is unsuccessful, check if there are any previous versions of PowerShell installed on your system. Uninstall them before attempting to reinstall PowerShell.
5. Review Error Messages: Pay attention to any error messages during installation. They can provide valuable information about missing dependencies, permissions, or other issues preventing the installation.
