This is not necessary if you installed with Homebrew.
Paths
$PSHOMEis/usr/local/microsoft/powershell/7.1.3/- User profiles will be read from
~/.config/powershell/profile.ps1 - Default profiles will be read from
$PSHOME/profile.ps1 - User modules will be read from
~/.local/share/powershell/Modules - Shared modules will be read from
/usr/local/share/powershell/Modules - Default modules will be read from
$PSHOME/Modules - PSReadline history will be recorded to
~/.local/share/powershell/PSReadLine/ConsoleHost_history.txt
The profiles respect PowerShell's per-host configuration. So the default host-specific profileexists at Microsoft.PowerShell_profile.ps1 in the same locations.
PowerShell respects the XDG Base Directory Specification on macOS.
Because macOS is a derivation of BSD, the prefix /usr/local is used instead of /opt. So,$PSHOME is /usr/local/microsoft/powershell/7.1.3/, and the symbolic link is placed at/usr/local/bin/pwsh.
