AIUI, PackageManagement really is literally just a convenience API for providing a consistent set of calls for driving arbitrary package management systems, and has no package management capabilities at all itself. It's actually not Windows-specific. The actual package management system for PowerShell modules is PowerShellGet. On Mac, PowerShell Core includes PackageManagement, and two "providers" - an adapter for PowerShellGet and one for NuGet, so you seem to be able to do either: Find-Module AWSPowerShell.NetCore (to use PowerShellGet directly) Or: Find-Package AWSPowerShell.NetCore (to go through PackageManagement)
