Remove the current battery and replace with one you know has power.

If the PC doesn’t detect any movement, try replacing the battery.

As these models of mice do not come with an LED power indicator, you’ll need to test the power by moving it and looking for the cursor on the PC’s screen. Using the 'Advanced' option.the keyboard is recognized (state goes from inactive to active when you pound on the keys), yet no characters appear either in the Unifying test box or anywhere in the computer itself.Move the mouse after placing it on the mouse pad to see if the PC recognizes the device. The usual workflow of cycling the power switch gets you nowhere.

Note that the Unifying software only recognizes the keyboard using the 'Advanced' option. Then verified that both the Logitech Control Center Deamon and the Logicool Unifying Software were enabled in the 'Input Monitoring' panel of the 'Privacy' tab of the 'Security & Privacy' System Preference Pane.Īfter updating the firmware on the Unifying receiver, it's possible to pair the keyboard using the 'Advanced' option in the Unifying software. There are probably 12 or so available Logitech downloads and it's not clear which ones are needed to get a specific piece of hardware functioning. And the 'Logitech firmware update' which recognized the Unifying receiver and reported a successful firmware update. I say 'appears' because it is the only download that lists 10.15 as an available Mac OS version. Then reinstalled what appears to be the most recent Logitech drivers for Mac: 'Logicool'. Apparently several versions were present and some dated back to 2015 or so. I completely uninstalled all Logitech software, preference panes, and the like.
