Tbh this is not good enough. I gave away all my razor mouse/keyboard etc due to rgb compatibility issues. Moved to icue and Corsair as it worked. Bought multiple devices and again compatibility issues with the lt100 and extender kits. This surely is not a mac issue as you have it working for the latest keyboards but kba to update icue to add lt100.very disappointed with the continued admin fob offs and no answer on a real road map if compatibility will ever be fixed. Shocking customer service especially with MAC becoming more popular again.
