…and that is the core of the state of the macOS version of the viewer(s). Deprecated code all over. 

Umm, the viewer does ship with its own OpenSSL which is exactly what Apple recommends.

When will be see the crash in the occlusion code being fixed due to the fact that GL_ARB_occlusion_query2 is not available in the OpenGL Legacy Profile the renderer currently is forced to when the viewer is running on macOS 10.11 or higher?

The viewer doesn’t ever call GL_ARB_occlusion_query2 on OSX.

This crash happens in Cool VL Viewer, Singularity, Alchemy, Firestorm, Kokua, SecondLife release and all dev versions including Second Life Project Alex Ivy
You probably never get it reported because the Google Breakpad reports don’t catch it. 

That has been reported and the crash reporter doesn’t catch it because it’s a driver crash not the viewer.

It’s not a viewer bug, it’s an issue with Apple’s Nvidia driver. (also note, that it doesn’t happen with Radeon or Nvidia’s own driver, just Apple’s and happens to hundreds upon hundreds of games available on Steam.)
