How to Install S & S Windows Applications on a MAC Computer Using Wineskin

Wineskin provides free Windows emulation support to run S & S applications on a MAC.

What is Wineskin?

Wineskin is a tool used to make ports of Windows software to Mac OS X 10.6 Snow Leopard (or later). The ports are in the form of normal Mac application bundle wrappers. It works like a wrapper around the Windows software, and you can share just the wrappers if you choose (that is the strategy used here). Best of all, it’s free and does not require installation of the Windows OS!
