Arduino -USB Adapter- Macbook doesn‘t work

Hello!
I made a Midi Controller using a Leonardo and it works fine with my Macbook if i use a Micro USB to USB C cable.
But i want to use a short cable Micro USB to USB 2 Adapter in the Controller chassis and then connect a USB 2 to USB C cable to the Macbook. But if i try this the Arduino won‘t turn on.
If i use a PC Notebook it works so i guess it has something todo with the Macbook not liking this Adapter.
Maybe someone got such Adapter working and can tell me what to buy.

This is the Adapter i bought:
