You can get a USB-C to USB-A adapter from Apple. It ties up one USB-C port and gives you one USB-A port.


USB-C to USB Adapter - Apple


If you have several devices to connect, there are other ways to do it. E.g., with


  • Simple hubs that have four or more USB-A (USB 3) ports, and that plug into a USB-C port.
  • USB-C hubs and docks with multiple downstream ports (some of which are USB-A ones)
  • Thunderbolt hubs and docks with multiple downstream ports (some of which are USB-A ones)


If you get a third-party adapter, check if it supports USB 3.0 speeds (some don't).
