The current implementation is WinForms-based and therefore by definition Windows-only.
I've created #10 to suggest noting that fact prominently in the read-me.

Making the module cross-platform, such as via Terminal.Gui, would be great, but amounts to a nontrivial effort.

A cross-platform version of Show-Ast would make for a great addition to the already Terminal.Gui-based Microsoft.PowerShell.ConsoleGuiTools tools (which currently provide Out-GridConsoleView and Show-ObjectTree), so I've created a feature request there:

• Consider adding a console-based, cross-platform implementation of Show-Ast (module ShowPSAst) PowerShell/ConsoleGuiTools#244

I have no plans to add OSX support. I would support a fork of the project that wants to go in that direction though.
