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 download this software anywhere on the internet, there are only Windows versions. Not sure what to do :-(
