the (same) version for Apple is a Bluetooth device. The version for Windows also has a radio sign, what I have not exactly looked at me - it's a Logitech special radio solution and would have with me caused a permanent associated additional smothering, even though I have a built-in Bluetooth receiver to which in turn the K810 keyboard works very well. It is to ignore a standard mE utter nonsense, which has established itself in the wireless environment for HID .. and would rather enforce their own propietary. And even so little confidence in it has a driver for Apple is not developed .. I advise on the device as long as it's not like the Apple device also supports normal Bluetooth.
