When typing the ' key or the " key on the IDLE Python application for macOS, the application. I think it might have something to do with that beta version of Tcl/Tk (8.5.9) as Python says it is 'unstable'.

Yes, this is a symptom of using the default Apple-supplied macOS Tcl/Tk.  See for more information as the warning in IDLE suggests.  If you are using Python 3.6.0 downloaded from, the simple solution is to install the latest Tcl/Tk 8.5.x (not 8.6.x) from ActiveState assuming your use is compatible with the ActiveTcl license.

Marco, did you see this message?
 (r"WARNING: The version of Tcl/Tk ({0}) in use may"
  r" be unstable.\n"
  r" for current information.".format(patchlevel))
Or is it somehow lost?

Ned, the version check for this message is only done for Cocoa.  Is this restriction correct?
