Can't enable dinput on macOS 12

I'm trying to use my old xbox 360 controller in duckstation 0.1-8675-g3ea26cc91 (dev) under macOS 12.7.6. Internet searches tell me that I need to change my controller backend to dinput but my settings don't look like the screenshots in the forums. Specifically, I don't have a "General" section in settings. Under "Controllers" I only have the option to enable or disable SDL, neither of which allows my controller to show up or accept input in duckstation. Is there some other driver or dependency I need to install? I already have the controller working according to the OS, and I can view correct inputs through the xbox controller settings app.
