Unifying devices not detected after macOS 10.12.1 Sierra update

We are aware that after updating from macOS 10.12 Sierra to macOS Sierra 10.12.1, Logitech Options software does not detect supported Unifying devices on some systems. 

To fix this issue, unplug the Unifying receiver and then plug it back into the USB port. If Logitech Options still doesn’t detect the device, you may also need to reboot your system.
