Think this might actually be a duplicate of https://bugzilla.xamarin.com/show_bug.cgi?id=28125.  In addition to the InvalidCastException, in the Application Output you see the same error from 28125: 
Could not register the assembly 'Xamarin.Mac': System.IO.FileNotFoundException: Could not load file or assembly or one of its dependencies.
File name: 'System.Drawing, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

This caught the nasty brokenness that Aaron saw a week early, I was just too overloaded to notice.

Good catch.

Fixed in latest master. 8fe4401d425c6572388034aaf2eb81aa13392a78
Will be fixed in cycle 5 soon.

I observed that Xamarin.Mac sample "AnimatingViews" is working fine. Now, On clicking button "Add" application does't throw any exception, and a 'SQUARE' are added to the view. I have checked other samples :
1. Button Madness.
2. DocAppicon.
3. DrawerMadness. 

Above all samples are also working fine. Here is the screecast: http://www.screencast.com/t/l4OXak6op

This issue has been fixed hence, I am closing this issue.
