Report Poseidon Z RGB - Not recognized on Mac OS X after Firmware Update in Mechanical Posted January 13, 2017 I followed the steps. After removing the software, the folder is no longer there so I wasn't able to do step 3. So I restarted, plugged in my keyboard and installed the software. Now its saying to "Please plug-in Gaming Device to start the AP configuration"] The keyboard doesn't appear to be on at all when I plug it in any of my USB drives, yet other devices I have plugged in via USB work like mouse, hard drives etc. Adding a device doesn't work either.
