Print Preview does not match actual PDF print output


In Rhino for Mac.

When printing to PDF from rhino, the output prints what the display color is. not only the print color.

So what I see on my screen is what I get, apart from the line thickness.

I would like to be able to print preview on my screen to be able to see the various line thicknesses I have changed. However, when I do this, the print preview shows everything as black unless it is specified in the print color. Why is this, if the actual print out put follows the display color settings. And how can I make the print preview keep the display colors, and show line thickness?

Here are some examples.
