I seem to recall years ago reading that the Cocoa (the NeXTstep derived API) menu code called into the Carbon (the classic Mac OS derived API) code to run stuff. But that was around Snow Leopard IIRC. That sort of stuff might still be around?
The Carbon API itself lasted until 10.15 (Catalina / 2019) for 32 bit apps, so there's presumably at least some classic Mac OS derived code in there until then.
Menus got moved away from Carbon on macOS 14.
You'll get this error if you try to use the Carbon menu APIs:
> References to Carbon menus are disallowed with AppKit menu system on macOS 14 and newer. Use instances of NSMenu and NSMenuItem directly instead
