Connect accessories to your Mac mini
Plug in a compatible keyboard, mouse, trackpad, or other optional device to start using Mac mini. You also need to connect a display when you first set up Mac mini (see Connect a display to Mac mini for details).
You can work wirelessly using Bluetooth® technology. Your Mac mini can connect to optional wireless devices such as Magic Keyboard, Magic Mouse 2, Magic Trackpad 2, peripheral devices, and wearable sport accessories.
