Is there any notification under macOS 14 when the user changes the Text Size accessibility setting?

Is there any way for a 3rd party macOS app to receive some sort of notification for a change to the Text Size accessibility setting in the Settings app? I have not been able to find any API for this. Several Apple apps (Mail, Notes, and others) update text size based on the setting. I'd like to do the same in my own macOS app.

Thanks for the feedback that there is interest in this. There is currently no API but I will forward the feedback to the right team!

  • Sorry but I am just now seeing your reply. How do the various macOS apps respond to the setting change?

    BTW - In my specific case, I'm using Mac Catalyst to port an iOS app to macOS. Ideally the change in setting in macOS would have the same effect as it does under iOS - the trait collection would be updated with the new size category leading to things automatically updating their size as appropriate.
