Homebrew tap for PowerShell Products

Warning

This tap is deprecated and no longer maintained.

PowerShell is now available directly from the official, signed and notarized .pkg installers published by the PowerShell project, as well as from Homebrew Core. Please migrate to one of the recommended installation methods below. The powershell/tap/* formulas in this repository no longer work.

Recommended installation

Official .pkg installer (recommended)

The PowerShell project publishes macOS .pkg installers for both Apple silicon (arm64) and Intel (x64) Macs. Beginning with the May 2026 releases, these packages are notarized and signed by Microsoft, so you can download and open them directly.

1. Download the .pkg for your processor architecture from the PowerShell releases page.
2. Double-click the downloaded package and follow the installer prompts.

To update, download and install the newer package. For full instructions, see Install PowerShell on macOS.

Homebrew (community formula)

PowerShell is also published to Homebrew Core, so you no longer need this tap. Install it with:

brew install powershell

If you previously installed PowerShell using the Homebrew cask, you must first uninstall the cask before you can successfully install using the Homebrew formula:

# Uninstall the PowerShell cask instance
brew uninstall --cask powershell
# Uninstall the PowerShell Preview cask instance
brew uninstall --cask powershell-preview

If you receive the message "Warning: PowerShell is already installed, it's just not linked.", run:

brew link powershell

To update PowerShell to the latest release:

brew update
brew upgrade powershell

Note

The brew formula is maintained and supported by the Homebrew community. It builds PowerShell from source code rather than installing a package built by Microsoft. See Alternate ways to install PowerShell for details.

Requirements

1. You must be running a version of macOS supported by PowerShell.
2. See Homebrew requirements.

Issues with PowerShell itself can be reported at PowerShell/PowerShell.
