  I don't understand this, I have been running my tkinter based
applications from within IDLE for years, on Mac, PC or Linux.
Am I misunderstanding something?

My biggest problems with IDLE on the Mac have been when python has
been compiled against one version of the tcl/tk libraries
but python is finding a different version of tcl/tk. Sometimes I
have needed to recompile python from sources. Other times I have
installed the asked-for version of tcl from ActiveState.

Try running idle from a terminal window. That way you can see the
error message when idle crashes. May suggest that the wrong tcl
is installed.

Some curios, if that if I don't have Python open, and double click on a program, Python opens the IDLE and the program in to separate windows without a problem, but when I try to run the program it freeze.

You should be able to run console applications from IDLE, but with tkinter applications you can develop them using IDLE but run them from a console (or whatever is used as a console on a Mac). It's nothing to do with the Python version or with ttk and I doubt it can be called a bug.
