I am using Rhino 6 for windows on a MAC computer using windows 10 via bootleg. When I import a picture into Rhino it appears as a white box. How can I fix that?
You probably can’t. My guess is the Windows drivers for the display adapter don’t meet Rhino’s minimum OpenGL standards to support that feature and a few others.
The only hope would be a driver update that does support it.
What graphics card is on your Mac, and what is the date of the Windows display drivers for it?
