Mitch Heynick released the first version of MicMacTools. This is a set of Python scripted tools from his library put together specifically for Rhino for Mac. They are an outgrowth or subset of his MaqueTools toolbar for Rhino for Windows.
The tools should work in Rhino for Mac 5.1 or later. The tools are not recommended for 5.0.2 or earlier.
