I am using logitech wireless keyboard K270 and Mouse M185 with my MACbook Air(currently OSX 10.10.5) for more than a year now. All of a sudden today after some time, my keyboard and mouse stopped working. I checked the batteries all seems to be OK. I connected the unifying receiver again after restart with Logitech Unifying software and got this message.
Has anyone faced this problem before, do I need to reinstall the Logitech unifying software again? I also can't even get this software download anywhere on net, the ones which are their are of windows. Not sure what to do :-(
