@9c799a92 I don’t use kIOHIDOptionsTypeSeizeDevice. The function is driven by Apple’s Game Controller framework (https://developer.apple.com/documentation/gamecontroller) May I know your macOS version, and which game is affected?
@83211688 Oh, right, sorry, I should have specified. Sonoma beta (latest), and it happens with anything, like Open Emu or Joystick Mapper or any game. Other apps detect the controller but don't receive input.
