• ok, what I found so far: it may be a problem with macOS 13.6.1.

    Under 15.0.1, the Puck was recognized as a BLE keyboard, but started the macOS "Keyboard Assistent" to "identify" the keyboard.

    This means, that (for macOS) the code of the Puck has to be a bit more complicated in order to pass the assistant first...(sigh)

    At least, I have a working basis now...
