Bug report

Bug description:

In the terminal of Macos Sequoia 15.1.1 the below logging is shown when using certain (GUI en TIU) frameworks. Not critical.

2024-11-26 22:43:42.634 python[33014:3805202] +[IMKClient subclass]: chose IMKClient_Modern
2024-11-26 22:43:42.634 python[33014:3805202] +[IMKInputSession subclass]: chose IMKInputSession_Modern# 

Minimal script:

import tkinter as tk
tk._test()

Seems that the OS falls back to a legacy version of the IMK input. Application are supposed to update the use of inputmethod at least that what's suggested...

CPython versions tested on:

This is a warning from an Apple system framework triggered from (in this case) the Tk library.

There's nothing we can do about this in CPython. Developers of GUI libraries like Tk and Qt may be able to avoid this output by changing to different APIs.

Also note that the last link is garbage output from ChatCPT (to safe anyone else the bother of reading it).

If you have a recent version of Tcl/Tk 8.6.x installed on the same version of macOS, you will probably see the same messages if you run a Tk app written in Tcl (no Python involved) from the command line, for instance starting the Tcl wish shell and then selecting its Widget Demo from the menu bar. If you would like to pursue this, the place to do so would likely be the Tk issue tracker here: https://core.tcl-lang.org/tk.
