What do you mean by this? On Mac, Tkinter/Tk uses native dialogs and 
widgets by default. What change did you make to get it to work on the Mac?

I did see the dialog hanging on the Mac. My guess is that you weren't 
giving the event loop enough time to spin; the dialog was popping up too 
fast. This code works just fine:

from Tkinter import *
import tkFileDialog
root = Tk()
def openfile():
     tkFileDialog.askopenfilename(parent=root)
b = Button(root, text="Open", command=openfile).pack()
root.mainloop()
