Is the SeparateDropDown style of toolbarbutton supposed to work on the Mac? Doesn’t indicate in the documentation that it won’t, but in assigning the style, it seems to only act as a dropdown (that is, no different than if it had been assigned as a dropdown style – no visual difference, either).
It is documented, just not easy to find. You have to know what you’re looking for which isn’t super helpful.

Separators aren’t supported on macOS and spaces aren’t supported on Windows; so I’ll usually stick one of each next to each other for a cross platform toolbar.
Nope, not the separator, but rather the SeparateDropDown style in the same list:
The ToolbarButton is a drop-down menu with a separate down arrow on its right. There is room for the caption and the icon. To specify the menu, assign it to the Menu property of the ToolbarButton class. Handle the selected menu item in the DropDownMenuAction event of the Toolbar class. See the example for the ToolbarButton class.
It only seems to handle the DropDownMenuAction; I would have assumed the difference with the normal DropDown type was that there would also be an Action for the non-dropdown part of the menu, but it doesn’t seem to be either visually apparent on the Mac or to actually fire.
