The Logitech MX Keys S and the Logitech MX Master 3S use different receivers. The MX Keys S generally use the Unifying Receiver, while the MX Master 3S uses the Logi Bolt Receiver. These two receivers are not compatible with each other, which means that you cannot operate both devices using the same USB receiver. However, if you have the MX Keys Gen2 or the MX Mechanical keyboard that support the Logi Bolt Receiver, you can connect them to the MX Master 3S via the same Bolt receiver. Alternatively, you can connect both devices via Bluetooth, which does not require a receiver. Here is a summary of the options: - Unifying Receiver: compatible with many older Logitech devices, but not the MX Master 3S. - Logi Bolt Receiver: Compatible with newer devices such as the MX Master 3S and some MX series keyboards. - Bluetooth: An alternative to connect both devices without a receiver.

Ja, gibt es: Logitech MX Keys für Mac (CH, Kabellos)

Hello, unfortunately not at all. This is the wrong keyboard. DE is the German layout. But you need the Swiss keyboard. The same mistake happened to me. I returned the keyboard and bought the CH version for the iMac. Now everything fits.
