Viewports no longer work in the latest Rhino 7 WIP update (7.0.20147.12475) when running virtualized in Parallels. Behaviour includes:

Hello - keep in mind that Parallels is not supported… it might work OK, or it might not…


Thanks @pascal – this is unfortunate.
Is there a way to downgrade to build 7.0.20140 or previous? All links in Rhino 7 WIP Available Now! point to the same download page…

It wouldn’t help for long so is not a viable solution.
WIP builds time out 45 days after they are created.

You will need to run V7 on a native Windows 10 system as a long term solution, or run V6 for Mac on your Mac.

which, as I understand it, could be Rhino for windows running under Bootcamp on a Mac, which is supported by McNeel…
Inconvenient of course if you want to use the same Mac for Mac apps and for Rhino since you will need to reboot with the operating system appropriate to what you’re doing,

Yes, provided your Mac meets Rhino for Windows System Requirements.
Many do not.
I do not use a bootcamp partition anymore. Too many problems.
I have separate computers for Mac and Windows Rhino.

I just ran into the same problem. Just the other way around. My RH7 Parallels works fine, but the RH6 Parallels does not move. I guess it has sth to do with the GPU settings. Everything worked fine some weeks ago. Maybe someone has an idea…


The question is not “why is it not working now?” it’s “How did it EVER work at all?”

Virtualization is NOT SUPPORTED, and there’s a reason for that, their support for OpenGL hardware is generally terrible. There are other solutions besides Parallels that are actually designed to give decent GPU support, but they’re still “not supported” so that’s at your own risk.

I get your point…
