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. Mac mini late 2012, Logitech wireless keyboard 800 (Unifying receiver, not Bluetooth)īackground (in case any Logitech engineers/experts are out there): Catalina installed without a hitch but my Logitech problem is a bit subtler.
