+## `Fn` Key on macOS
-## Apple/Mac Keyboard `Fn`
+Unlike most Fn keys, the one on Apple keyboards actually has its own keycode... sort of. It takes the place of the sixth keycode in a basic 6KRO HID report -- so an Apple keyboard is in fact only 5KRO.
-Apple/Mac keyboard sends keycode for Fn unlike most of other keyboards.
-I think you can send Apple Fn key using Apple venter specific Page 0xff01 and usage 0x0003. But you have to change HID Report Descriptor for this, of course.
+It is technically possible to get QMK to send this key. However, doing so requires modification of the report format to add the state of the Fn key.
+Even worse, it is not recognized unless the keyboard's VID and PID match that of a real Apple keyboard. The legal issues that official QMK support for this feature may create mean it is unlikely to happen.
+See [this issue](https://github.com/qmk/qmk_firmware/issues/2179) for detailed information.
