Darwine is described as 'The Darwine project intended to port and develop Wine as well as other supporting tools that would allow Darwin and Mac OS X/ppc users to run Windows applications and to provide a Win32 API compatibility at application source code level'. There are six alternatives to Darwine for a variety of platforms, including Mac, Linux, Wine, BSD and Android. The best alternative is Wine, which is both free and Open Source. Other great apps like Darwine are PlayOnLinux (Free, Open Source), CrossOver (Paid), WineBottler (Free, Open Source) and Wineskin Winery (Free, Open Source).
Wine is a free, open source application for running Windows software on operating systems that are normally not supported. With Wine, you can install and run these applications just like you would in Windows.
Wineskin is a tool used to make ports of Windows software to Mac OS X. 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. Best of all, its free!
Run your Windows applications on OSX without the need of buying a Windows license. Well, you even do not need to install Windows. Just download WinOnX and you are ready to go within 2 minutes. No need to install Windows or a virtual machine.
