Thanks for the suggestion. Moving the OS X installers to using Tcl/Tk 8.6 is
the subject of Issue15663.

New submission from Aivar Annamaa:
Currently Mac installer can create only Tk 8.5 compatible Tkinter, even if
Tcl/Tk 8.6 is installed.
Unofficial distributions doesn't seem to have problems with Tk 8.6 on Mac. I
think official installer should be upgraded as well.
