Officially, Microcase won't run on Mac because it hasn't been developed for this operating system, you can run it using Windows emulation. This can be achieved with the Bootcamp application found within the OS or using Paralells Desktop. These apps allow you to run Windows even if you have a Mac.
Secondly, you could try using Wine Bottler since it can run Windows apps without Windows installed.
