On Linux, this code toggles the checkmark on a checkbutton in right-click menu. On OS X 10.12 it doesn't.

OS X 10.12, python 3.6.0b4.

#!/usr/bin/env python3
import tkinter as tk

class NodePopup(tk.Menu):
    def __init__(self, master):
        super().__init__(master, tearoff=0)

        self.send_disabled = tk.BooleanVar()

        self.add_checkbutton(label="Disable sending",
                             variable=self.send_disabled, command=self.toggle_send)

    def popup(self, event):
        print('send_disabled before:', self.send_disabled.get()), event.y_root)

    def toggle_send(self):
        print('send_disabled after:', self.send_disabled.get())

def change():
    state = not menu.send_disabled.get()

root = tk.Tk()

menu = NodePopup(root)
root.bind('<Button-2>', menu.popup)

I'm not totally sure what behavior you expect but it *seems* to work OK for me using the current Python 3.5.2 or the pre-release 3.6.0rc1 from OS X installers and with current ActiveTcl 8.5.18 installed as suggested (  If you default to using the very out-of-date and buggy Apple-supplied system Tcl/Tk 8.5.9, the checkmark does not appear.
