hidapi's macOS backend opens every device with kIOHIDOptionsTypeSeizeDevice unless told otherwise (hid_init() calls hid_darwin_set_open_exclusive(1) for backward compatibility). When 3DxWare is running it already holds the SpacePilot/SpaceMouse, so the seize fails, hid_open_path() returns NULL and HidBackend::scan() keeps retrying every 3 s without ever finding the device. Reported in discussion #599: a SpacePilot Pro (046d:c629) is listed by hid_enumerate() and works in 3DxWare, but has no effect in QET's macOS build. Enumeration never opens a device, so it did not exercise this. Guarded on HID_API_VERSION >= 0.12, where the setter first appeared. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
