C is a sane language?

#4> For some reason if we run the app from command line than menu is not accesible by mouse at first time
This happens with Qt apps on OS X, as well, and it drives me bonkers. If you launch from the command line you have to command tab away and back for the menu to work

#5There was a thread the other day where people were talking about languages that were easily interoperable with the "C ABI" (although there is no such thing). Languages listed included C++, Rust, and maybe a few others--but no mention of Objective-C.
The ability to use a high-level, dynamic language (ObjC), C, and even inline assembly in a single source file is unique to Objective-C (at least among the "mainstream" languages), and something I think is often under-appreciated.
One comment on the code here: for message calls returning type 'id' (object type), you don't need to cast the dispatch function. It would make the code much more readable. For other return types, you need a cast, but I'd wrap it in a macro. You could even use a C11 generic macro to handle floating point return values (unfortunately necessary).

#7If you compile it, you'll see that the ObjC executable with no ARC and the C-only executable are exactly the same size stripped. The ObjC version with ARC is 392 bytes bigger.

What else would it be? objc_msgSend() is called as a C function, to interface with ObjC code.

...objc_msgSend() is a plain C function that grovels around in various runtime data structures to call the correct function pointer for GUI and OS functionality.
Any alternate method of finding and calling those functions would amount to simply reimplementing objc_msgSend()

Really? I don't write systems software but it seems most here would not recommend writing in C/C++ unless it's absolutely the best choice.
