Hi Ben -
I suppose you could try that, but reinstalling is not likely to do anything.
If you are installing final Service Releases (i.e. not release candidates), this sounds like both 8.6 and 8.5 are now failing, and that, perhaps, 8.4 was working.
On macOS, you can have different versions “installed” at the same time by dragging the Rhino icon onto the desktop instead of onto the “Applications” folder, and then giving the instance on the desktop a unique name, e.g. “8.5”.
Please download and install 8.5 and 8.4 to check if any of those work as expected.
That’s along the same line as I was thinking, yes. But making a new layout in a new file will ensure that the “Wireframe” mode will be used. I was checking if that display mode had gotten modified to not show curves and annotations, but, as Ben writes, changing to “Wireframe” in a detail still shows the curves and annotations in that detail. At least, that’s how I interpreted the following:
Just to make sure, is that interpretation correct, Ben?
