Hello, I have a external USB Bluetooth dongle working on El Capitan on my mac. But while its working it blinks a blue led light. Its annoying. I want to disable it inside drivers but I couldnt do that. I found its kext files under extensions IOBluetoothFamily.kext/Plugins/CSRBluetoothHostControllerUSBTransport.kext IOBluetoothFamily.kext/Plugins/CSRHIDTransitionDriver.kext I couldnt find any string about LED or Light, I think I have to add a new string to disable led but I dont know what is it exacly. Anyone has any idea? Thanks.
