Store page is completely incorrect, controller not usable at all. Works fine with every other application.
Enjoyable mapping can work, but extremely difficult to get mouse movement to work fluidly enough to play the game, and that is not controller support, that is a workaround that does not work; you won't be able to aim yourself in correct direction easily, it's not real controller support you're better off using mouse and keyboard.
Similarly, full screen (including borderless windowed) will cause the mouse input from controller to stutter.
If you want to try it, be sure to allow permissions for both Children of Mortal + Enjoyable in System Preferences.
Tested on MacOS Sequoia (15), very disappointing.
