OpenGL on Mac OS X Sierra does not draw a triangle, what should I do?

Question

macOS

I can't figure out what's wrong. In windows, everything works, it doesn’t want to on a poppy (just a window with a black background).
This is what the console outputs:
2018-01-12 16:17:59.613642+0500 test[5837:1493716] [General] ERROR: Setting as the first responder for window , but it is in a different window ((null))! This would eventually crash when the view is freed. The first responder will be set to nil.
