Just a quick note, for those who are having trouble using the Ducky One 2 Mini (DKON2061ST) with a Mac: Updating the firmware to V1.09 helps a great deal with the recognition of the keyboard.
However, the update did not help with being able to use a USB cable other than the one included. The included USB-A to USB-C cable now works fine (with an adapter). A generic USB-C to USB-C cable, which I use with my Keychron K6, for example, still does not work.
Updating the firmware is relatively easy, but it requires a Windows computer.
