I need a USB port for my MacBook. What should I look at?

Use this: USB-C Digital AV Multiport Adapter

By using that, you will not lose the USB C connection and you can use the USB-A connection along with an HDMI connection built into it. So, if you still need to power up your Mac, you can use the USB C port on this adapter.

Connections:

• HDMI
• USB
• USB-C

Hi,

USB-C to USB adapter is available at Apple Store.
