Thank you for ckb-next. It works with my K65 Lux RGB keyboard on an older MacPro (3,1; early 2008) running 10.11.6.
ICue refuses to install.
I use AppCleaner to remove it and then I have to find and remove a startup deamon located in /Library/LaunchDaemons/
Now a general question about ICue. What is the lowest, oldest version of macOS iCue will support?
Update: Firmware on the K65 was old. Updated to version 3.0.8. iCue still fails to install. Thinking there is another issue but don't know what it is. I could look in the Console if someone can point me where to look. Doing a search on iCue doesn't reveal anything glaring at this time.
