A Media Access Control (MAC) address is a unique, 12-character alphanumeric identifier assigned to a network interface for communications on a physical network segment. While most people are familiar with finding the MAC address of their computer’s Wi-Fi card, every Bluetooth device—from wireless headphones and mice to smart speakers—also has a unique Bluetooth MAC address. If you are configuring strict MAC filtering on a corporate network, writing a custom automation script, or diagnosing severe connectivity issues on your Mac, you may need to find the exact hardware address of your connected Bluetooth accessory.
Finding the MAC Address via the System Information App
The easiest and most reliable way to find the exact MAC address of any Bluetooth device paired with your Mac is by using the built-in System Information utility.
- Ensure the Bluetooth device in question is turned on and actively connected to your Mac.
- Hold down the Option (⌥) key on your Mac keyboard.
- While holding the Option key, click the Apple Logo () in the top-left corner of your menu bar.
- Because you are holding the Option key, the first menu item will change from “About This Mac” to System Information…. Click it.
- A new window will open displaying a comprehensive hardware report. Look at the sidebar on the left.
- Under the Hardware section, locate and click on Bluetooth.
- In the main pane on the right, you will see a list of your Mac’s Bluetooth radios and all paired devices. Look under the Connected (or sometimes ‘Devices’) section to find your specific accessory.
- Below the accessory’s name, you will see its technical specifications. Look for the line labelled Address:.
- The string of letters and numbers (formatted like `AA:BB:CC:DD:EE:FF` or `aa-bb-cc-dd-ee-ff`) is the device’s Bluetooth MAC address.
Alternative: Using the Bluetooth Menu Bar Icon (macOS Monterey and Earlier)
If you are running an older version of macOS (Monterey or earlier), there is a slightly faster shortcut available directly from the menu bar.
Hold the Option (⌥) key and click the Bluetooth icon in your top menu bar. The drop-down menu will expand to show advanced technical details. Simply hover your mouse cursor over the name of your connected device in the list, and a small pop-out menu will display its MAC address, connection quality (RSSI), and active role.
Note: Apple redesigned the Control Centre in macOS Ventura and Sonoma, removing this specific Option-click functionality from the menu bar. If you are on a modern macOS version, you must use the System Information method detailed above.
