Has anyone else here had the problem of their viewports going completely black for no particular reason? only way to fix it is to restart rhino. rhino is still responsive, and some non black lines are still visible, though any regular (grey) surfaces also go black.
At a guess, that sounds like either a file specific issue or a graphics card problem which could be hardware or driver related.
Can you click on About Rhinoceros from the Rhinoceros menu and then More Info. Please copy and paste the information about your system from there.

If you can still see some non-black lines in a viewport, then this likely has nothing to do with your graphics card or OpenGL drawing in general. I have this exact same McBook Pro and have never seen something like this.
Does this happen in all display modes, even wireframe? Have you changed any of the display mode settings?
Happened again yesterday. I was running in ghosted mode this time. One odd thing I picked up this time was that the blackness disappears while you are moving the camera position and reappears as soon as you stop moving. Next time it happens I’ll get a screenshot, and also try changing display modes. I havent changed any of the display mode settings (except a few days ago I changed the edge thickness from 2 to 1 (but the black viewport thing had been happening before that)
As I said, I don’t see this problem, and nobody else has been reporting this either.
You have quite a few third party kernel extensions installed. The com.paceap.kext.pacesupport.snowleopard extension has snowleopard in its name. Are you sure this is compatible with OS X Mavericks?
You might try disabling some of your other kernel extensions and see if that changes the viewport behavior.
