Hello!I encountered a problem in my OS X app. I'm using both IOKit HID devices and GameController.framework devices.Problem is, all GCController devices have HID devices, and I didn't find any way of matching them.So, here are questions:1. Is there a way to say "this IOHIDDeviceRef device is MFi controller which would be handled by GameController.framework"?2. This GCController and IOHIDDeviceRef object refer to same physical controller and I can ignore/blacklist one of them in my code to avoid duplicationsN.B.There is [GCController deviceRef] field. In fact it is IOHIDDeviceRef, so I can get their IOHIDDeviceGetService and then IORegistryEntryGetRegistryEntryID to see if they're same connected device.Problem is - deviceRef is a private field. I'm not sure if I can use it when submitting app to App Store

Bonjour 3 is not a part of iTunes 12.7, and it is not available in https://support.apple.com/downloads/Bonjour%2520WindowsI do not understand why this things don't co-exist. This seems to be major oversight: to get Bonjour on Windows one must now download old version of iTunes, and then upgrade it to new one for bonjour to remain. This seems very inconsistant.
