As I understand it, the keyboard and mouse can be tied to up to 3 different computers and a keypress moves between them.
As well, I think there are options for both to come with a dongle.
Is the dongle specific to the keyboard / mouse or can I put one dongle in computer A and have both the keyboard and mouse connect to that computer via that dongle and then put the second dongle in computer B and have both use that dongle.
I’m thinking this would avoid having to use bluetooth for them.
I have multiple dongles and paired them to each of the three settings. Laptop, desktop and work laptop. You can use the Logitech Unifying software to pair them with each dongle: Unifying Software – Logitech Support + Download
Make sure you don’t buy the “Business” version of the MX Keys and MX Master 3 as they use a different wireless protocol called “logi bolt” and need different dongles (which I think are not yet available for separate purchase)
Just an FYI, the ‘Mac’ version of this mouse does not include the Unified Receiver. I have the non-Mac version, and it works just fine with my Mac, iPad, work laptop (Windows 10) and Raspberry Pi.
And while I have the Unified Receiver I use the mouse over Bluetooth.
