Can I switch my mouse and keyboard at the same time using one Easy-Switch button?

It is not possible to use one Easy-Switch button to at the same time change both your mouse and keyboard to a different computer/device.

We do understand that this is a feature that a lot of customers would like. If you are switching between Apple macOS and/or Microsoft Windows computers, we offer Flow. Flow allows you to control multiple computers with a Flow-enabled mouse. Flow automatically switches between computers by moving your cursor to the edge of the screen, and the keyboard follows.

In other cases where Flow is not applicable, one Easy-Switch button for both mouse and keyboard might look like a simple answer. However, we cannot guarantee this solution at the moment, as it is not easy to implement.

Volume keeps increasing after I press the volume button on my keyboard

If the volume keeps increasing or decreasing after you press the volume button on your MX Keys keyboard, please download the firmware update that addresses this issue.

For Windows

For Mac

NOTE: If the update doesn’t install the first time, please try running it again.

Play/Pause and media control buttons on macOS

On macOS, the Play/Pause and media control buttons by default, launch and control the macOS native Music app. The default functions of keyboard media control buttons are defined and set by macOS itself and therefore cannot be set in Logitech Options.

If any other media player is already launched and running, for example, playing music or a movie onscreen or minimized, pressing the media control buttons will control the launched app and not the Music app.

If you wish your preferred media player to be used with the keyboard media control buttons it must be launched and running.

Bluetooth mouse or keyboard not recognized after reboot on macOS (Intel-based Mac) – FileVault

If your Bluetooth mouse or keyboard does not reconnect after a reboot at the login screen and only reconnects after the login, this might be related to FileVault encryption.
When FileVault is enabled, Bluetooth mice and keyboards will only re-connect after login.

Potential solutions:
– If your Logitech device came with a USB receiver, using it will solve the issue.
– Use your MacBook keyboard and trackpad to login.
– Use a USB keyboard or mouse to login.

Note: This issue is fixed from macOS 12.3 or later on M1. Users with an older version might still experience it.
