Description

What's the problem? Describe what went wrong.

On MacOS, when setting up controller configuration - at least with the Sony DualShock 4 Controller, when used over Bluetooth - clicking any of the controller mapping buttons results in a hang, forcing the user to force-quit the application in order to proceed, and disallowing mapping of controller buttons.

What steps will reproduce the problem?
1. Pair and Connect Sony Playstation DS4 over bluetooth to macOS.
2. Launch Dolphin on MacOS
3. Click Controllers -> GameCube Controllers Standard Controller
4. Select Input/X/Wireless Controller from the device menu
5. Try to map the A button.

Result: Immediate rainbow pinwheel.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Unsure.

** Additional **

I have built a debug version of dolphin and have attached the Xcode debugger to it, resulting in the following call-stack:
