Working with Rhino WIP, having problems in Render Mode

Hi everyone,

Working on Rhino WIP. When I go to render, I get a screen with a bunch of dots on it, and an entirely different screen of tools. The rendering timer will proceed proceed but with no rendering appearing on the screen, just a screen of dots.

Anyone have any ideas on what’s up with this problem. I am working on a MAC.
Thanks in advance as always for any help.

It would help if you posted a screenshot of the issue, as well as copy&paste the result of the command _SystemInfo
