Receiving +[IMKClient subclass]: chose IMKClient_Legacy logs after updating to MacOS Sequoia

Description

I am not sure if this is a MacOS Sequoia bug, or something winit needs to fix.

When I run any winit-based app on my Mac, I get messages like this:

2024-09-25 11:41:42.291 rust-testing[86791:3027734] +[IMKClient subclass]: chose IMKClient_Legacy
2024-09-25 11:41:42.291 rust-testing[86791:3027734] +[IMKInputSession subclass]: chose IMKInputSession_Legacy

When I searched the message, I found that some other non-winit projects are having this issue as well, which makes me think it could be a MacOS Sequoia bug.

macOS version

ProductName:		macOS
ProductVersion:		15.0

I also noticed this just a few days ago, quite possibly right after I updated to Sequoia.

Sounds like a macOS bug indeed, a quick internet search reveals a few other instances.

Would be nice if someone could create a bog-standard macOS application in Xcode, perhaps with a text field (since it sounds related to the issue), and see if the problem is present there too?

In any case, I'll leave this issue open for a while for visibility, though I doubt there is anything for us to do.

I tested it with the default Xcode MacOs app template. The issue occurs there as well.

Nothing to do then other than reporting the bug to Apple.

Hi, do you still have the bug after macOS 15.0.1 update ?

Yes, it is still occurring

Updated to macOS 15.1 just now, still occurring.
