Connect accessories to your MacBook Pro
You can connect your MacBook Pro with other devices, like a keyboard, mouse, or trackpad; wearable devices like AirPods; and more. There are two ways to connect accessories—wirelessly, with Bluetooth, or by connecting the accessory to one of the USB-C ports on your MacBook Pro with a cable.
What type of accessory do you have?
 Wireless accessory If you have a wireless accessory that uses Bluetooth to connect, you can pair it to your MacBook Pro.

See Connect an accessory with a cable. |
Connect a Bluetooth accessory
The first time you use a Bluetooth accessory with your MacBook Pro, you must pair them.
Step 1: Turn Bluetooth on. Click 
Step 2: Pair a Bluetooth accessory. Check the documentation that came with your accessory to make sure it’s ready to pair—for example, you may need to flip a switch or press a button on the accessory to turn it on. Your MacBook Pro and the accessory must be near each other.
When your accessory is ready to pair, open System Settings on your Mac and click Bluetooth in the sidebar. Select the accessory in the Nearby Devices list, then click Connect.
Step 3: Connect a Bluetooth accessory. Your accessory automatically connects to your MacBook Pro after you’ve paired it. If an accessory doesn’t automatically connect, open System Settings and click Bluetooth. Make sure the accessory appears in the My Devices list. If it does appear, click it to connect. If it doesn’t appear, follow the steps to pair the accessory.
Tip: If you want to disconnect a Bluetooth accessory after it’s been connected, open System Settings on your Mac and click Bluetooth. In the My Devices list, move your pointer over the accessory, then click Disconnect when it appears. To forget a Bluetooth accessory so your MacBook Pro doesn’t automatically connect to it, click 
Connect an accessory with a cable
Step 1: Check the documentation. Review the documentation that came with your accessory to make sure you understand how it works. For example, some accessories have an additional power source that also needs to be plugged in.
Step 2: Use the correct cables and adapters. Your accessory may come with its own cable. If it doesn’t, you need to obtain the correct cable—review the accessory documentation if you’re not sure which type of cable to use.
If the cable you have doesn’t have a connector that fits the Thunderbolt (USB-C) ports on your MacBook Pro, you need an adapter. For more information about adapters, what they look like, and what ports to use, see Adapters for the Thunderbolt or USB-C port on your Mac.
Step 3: Attach the cable to your MacBook Pro. Connect the cable, using an adapter if required, to one of the Thunderbolt (USB-C) ports on your MacBook Pro. You may also need to connect the cable to a port on your accessory.
Depending on the capabilities of the accessory and the cable, you may also be able to charge the accessory or transfer data when they’re connected.
Tip: Some accessories need to be approved the first time they’re connected. See Allow accessories to connect to Mac to learn more.
