I’m a student and I have installed rhino 7 in my mac, but when i open a stl file, it doesn’t appears anything, if i move the mouse it seems it’s moving but i can’t see the design
My mac is a Imac 2011 - 16 GB RAM - AMD Radeon HD 6750M 512 MB with Catalina OS.
So it’s somewhere I think. Did you try a Zoom>All>Extents? Or while the mesh is selected, Zoom>Selected? Try different display modes?
However, that being said your specs:
…are completely inadequate for running Rhino V7. I don’t know how you actually got Catalina installed on a 2011 Mac. So your display might just not be working, and probably will never work correctly.
