Question details
Users encounter a WSMan error stating that no supported WSMan client library is available when running PowerShell commands on a Mac.
- Product
- PowerShell
- Device & OS
- macOS
- Scenario
- Executing PowerShell scripts or commands that rely on remote management features via WSMan in a macOS environment.
- Observed behavior
- PowerShell displays an error indicating that the selected parameter set requires WSMan, but no supported WSMan client library can be found on the system.
Ensure you have administrator (sudo) privileges on your Mac and an active internet connection to download the required PowerShell modules.
Install the PSWSMan Module and Client Library
Resolve the missing library error by installing the WSMan components directly from the PowerShell gallery using terminal commands.
PowerShell on macOS does not come with native WSMan libraries pre-installed. You need to manually install the PSWSMan module and deploy the libraries to enable remote management features.
Launch the Terminal application on your macOS device from the Applications > Utilities folder, or by searching for it in Spotlight.
Type the command `pwsh -Command 'Install-Module -Name PSWSMan'` and press Enter to install the module from the repository.
Run `sudo pwsh -Command 'Install-WSMan'` in the terminal. You will be prompted to enter your administrator password to install the required client library.
Close your current Terminal window and open a new PowerShell session to ensure the newly installed WSMan libraries are loaded correctly.

Frequently Asked Questions
What is WSMan and why does PowerShell need it?
WSMan (WS-Management) is a standard protocol used for remotely managing IT systems. PowerShell relies on it for specific remoting features and cmdlets, which require dedicated client libraries to function properly on macOS.
Why do I get a 'no supported WSMan client library' error on Mac?
macOS does not natively include the specific WSMan libraries required by PowerShell Core. Because they are missing by default, you must manually install the PSWSMan module to bridge this compatibility gap.
Do I need sudo privileges to fix this error?
Yes. While downloading the module might not strictly require admin rights, running the `Install-WSMan` command requires sudo privileges to securely place the necessary libraries into the protected system directories on your Mac.
