I recently updated my Rhino WIP to the latest version and then I couldn’t open Grasshopper anymore. When I type in the Grasshopper command, Grasshopper loads and then closes my Rhino together before the loading is finished. Does anybody else experience the same problem?
Grasshopper is working OK for me on 5E366w.
Are you using a Commercially licensed copy of Rhino 5 for Mac? Or are you still “evaluating” Rhino for Mac?
If it’s the later,
Grasshopper will not launch (or autocomplete) if you are outside the 90 day evaluation period.
