Hmm, got a link for that?
The Cycles settings are used only in Raytraced, they donât do anything in any of the other display modes.
yes displays same whether using CPU or GPU 
The OSX CUDA driver page to use is https://www.nvidia.com/object/mac-driver-archive.html
A web driver version is at https://www.nvidia.com/download/driverResults.aspx/96651/en-us, but I donât know if it is the latest⌠-> maybe https://www.nvidia.com/download/driverResults.aspx/127670/en-us
TBH this sounds all way to complicated for the regular user. Finding and installing drivers on Windows machines is much easier

yep, when I fist installed High Sierra I regretted it the very next day
Well, the webdriver path is a fail, too. The installer claims incompatibility. I donât know how I can get CUDA support to work then
For now I suppose Nvidia GPU users on Mac should just stick to CPU, even if they magically managed to enable CUDA supportâŚ
Assigning this to @jeff to further investigate the other display mode problems you have.
Hi @milezee
Pen mode and Arctic mode are two completely different kinds of modes⌠Arctic mode is closer to a Rendered mode⌠What does your âRenderedâ mode look like using the same example and settings?
Thanks,
-Jeff
If that is with an empty model and just a box added itâll look the same since the default material is an almost-white, and further has pretty much the same settings as Arctic.
Add a material to the box, say a red plaster, or a chrome metal. You should now see the difference between Rendered and Arctic.
Edit: ah, your earlier arctic is obviously wrongâŚ
@nathanletwory He already did that
Look up further in the postâŚArctic mode just produces a wireframe box.
Yes, I actually knew, I just had forgotten.
yep Arctic just turns the grid lines white and displays what looks like wireframe
This is very odd indeedâŚ
Please try resetting Arcitic modeâs defaultsâŚ
and see if it makes any difference⌠I notice in your image that âFlat shadingâ is also checked⌠What happens if you uncheck that? Does the Rendered mode still look correct?
-J
@jeff @nathanletwory ok resetting to default display modes seems to get most working as expected, there is still âconfusionâ when switching between Arctic & Raytraced, notice in the screenshot attached that the right hand side bar is showing Arctic, but the right click drop down from the viewport is showing Raytraced, its like they are working independently if that makes sense
edit- yep, the display modes of Arctic and Raytraced are mixed up somehow
I think youâre just seeing the poor interaction between the side bar and the setting/changing of a viewâs display mode.
For now, I would only rely on what the dropdown view menu shows you, as that is what the view is referring to⌠The side bar gets notified when a viewâs mode changes, and then updates accordinglyâŚand that is probably not working 100% on the Mac version at the moment.
But my current concern at the moment is whether your view modes are working correctly⌠So without using the side bar (or even looking at it)⌠Cycle through all display modes and see if you get the expected results.
Thanks,
-Jeff
P.S. Iâm also concerned why resetting the defaults âfixedâ what ever it was that was broken⌠Have you been using older versions of Mac Rhino? Or is this the first installation of Mac Rhino that youâre using?
yeh all seem to be displaying as expected now 
have V5.5 installed and V6 Wip latest release
still getting instant crash when switching to raytraced
