UPDATE: Speckle was installed on both Mac OS and Windows, running Blender 4x and 3x respectively.
The issue was that there is a warning in both OS’s, and Speckle is not enabled automatically. Thus, when the “Enabled Add-ons Only” is checked it will not show up. If that is unchecked, Speckle does show up, not checked. There is a warning, which can be ignored, and then checked manually.
There-after it works are expected. I have to find out what WIP means. Assumption is “Work in Progress”, which would be OK.
