MacRuby basically allows developers to write Mac OS X apps in Ruby code and run them without a glitch on the OS as a native app.
What this means is that Ruby developers won't have to educate themselves in the intricate and complicated World of Objective-C programming, but use the language they know and love dear to code powerful Mac apps that don't sacrifice performance over inter-interoperability.
This is mainly because of MacRuby's built-in support for basic Mac technologies mentioned above.
