If you have purchased Rhino 5 for Mac, you have access to our Work-In-Progress (WIP): Rhino for Mac WIP. The WIP is where we are testing out new features, bug fixes, and other improvements.

Rhino for Mac WIP SHOULD NOT be used for mission-critical work as it may be unstable.
The Rhino for Mac WIP build can be run side-by-side with the full, stable, commercial release. They are two separate applications:
Rhino (the commercial release) and Rhino for Mac WIP have two separate update systems. Rhino for Mac WIP will be updated more frequently than the commercial release.
Rhinoceros and RhinoWIP share preferences and a license.
