Ah, k. Sorry, I'm really new at this stuff haha.. I set the MODE A and B to OFF. I also noticed that the KBDTransCh setting under [UTILITY] > [F5]...

Ok, thanks for the help! Under "Utility" -> "Other" I have set ThruPort - 1. The driver I installed is version 1.3.2 for Mac OS. I am also on macOS...
