This is currently the most ridiculous and annoying thing in the MacRhino interface.
First, you put a big, fat gearwheel icon out there in the main toolbar - and you even put a tooltip on it that says “Options”. Then as soon as someone clicks on it you get a message like: “Hey idiot! Why the !@# did you click on this icon? It doesn’t lead anywhere. Boy, you really are dumb, only stupid Windows users would try this! Don’t you know your way around a Mac?”
This is just completely mean-spirited and not at all like the Rhino philosophy I am used to.
Either:
Take out the gearwheel icon as well as the Tools>Options menu item out completely and let people “find” Rhinoceros>Preferences, or,
Make the gearwheel icon go directly to Preferences without beating people over the head.
There’s enough space in the top toolbar to have icons for “Settings” (document properties)" as well as “Preferences” (Options)
