I tried this (although, my tl is actually a tk instance):

self.tk.call("::tk::unsupported::MacWindowStyle", "style", self.tk._w,
"plain", "none")

and get this message:

Traceback (most recent call last):
  File "./ProgramCountdown.py", line 120, in <module>
    control = Controller(tk)
  File "./ProgramCountdown.py", line 37, in __init__
    self.tk.call("::tk::unsupported::MacWindowStyle", "style",
self.tk._w, "plain", "none")
_tkinter.TclError: bad class: should be alert, moveableAlert, modal,
moveableModal, floating, help, or document

Any thoughts? Can you do something similar on the tk instance itself?
