Exporting Rhino 5 to Rhino 4 on a Mac

Can anyone tell me why I can’t export/save down to Rhino 4 from the free trial verision of Rhino 5 on Mac? Each time I try to do so I get an error.


This is working here in the latest Mac Rhino work in progress build 519. I used the Export option in the File menu and then chose Rhino 4 as the file type from the drop down list.

Yes, I did that, but I then get an error notification telling me that the export failed. I unistalled and reinstalle it twice after and the same continues to happen.

Can you post the file? Are you also using the 519 build?
