Mac OSX tkinter.TclError - fix inside

Hi
On some OSX systems the GUI does not start because of an tkinter error:

This seems to be a problem with the Tcl/Tk version 8.5 that comes with the python3 version installed with 'brew'. It can be fixed by uninstalling python3 and manually reinstalling it with the latest version from https://www.python.org/downloads/.

With the fix provided there is nothing more to do here. Thanks for pointing this out for all Mac OS users.

The following solution is also useful for ubuntu users, because it is not recommended to uninstall default python from ubuntu:
