Have the exact same issue. In my case the laptop keyboard does not even type the correct keys when trying to log in Mac when my k95 rob platinum is connected. I have to unplug it, use the laptop keyboard to login and replug the K95. It then works fine, even to wake up after sleep. My OSX is the latest Catalina version. I am using the latest ICue for Mac. I contacted Corsair tech support. They asked me to and I did a soft reset, a hard rest, force updated to latest hardware, and even prayed. nothing works. I am about to ditch it
