Pipe Flow Software is Windows-based and cannot be run directly on OS X on your Apple.

However, you can use Parallels or VMWare Fusion software to install Windows onto your Mac, and you can then install and run Pipe Flow software.

Parallels is relatively low-cost at about $80 USD and may be worth the investment to allow you to run the wide array of Windows software that is available. You will also need a copy of Windows to install within Parallels.

You will then get the benefit of being able to run any Windows program on your Mac (it works really well, and you can seamlessly be running Windows apps alongside apps from your Mac desktop).
