Bluetooth device won't pair with your Mac

Why it happens

A Mac can only see a device that's in pairing mode, which most devices leave after a minute or two. Many also connect straight back to the phone or computer they used last, so your Mac never gets a turn. An old, half-finished pairing can block a new one too.

How to fix it

1. Charge the device or fit fresh batteries. Low power is a common reason pairing quietly fails.

2. Put it in pairing mode. On most headphones and speakers you hold the power or Bluetooth button until a light flashes, but check the manual for yours.

3. If it pairs with your phone, turn Bluetooth off on the phone for now so the device doesn't jump back to it.

4. On the Mac, open System Settings and click Bluetooth. Keep that window open and wait for the device to appear under Nearby Devices. Hold the pointer over it and click Connect.

5. If the Mac shows a code or asks you to accept, click Accept, or type the code on the keyboard you're pairing and press Return. The device then moves up to My Devices.

Still not fixed?

1. Device not in the list? Turn it off and on, hold its pairing button until it flashes, and keep the Bluetooth window open while you wait.

2. If the device is already listed but won't connect, Control-click it in Bluetooth and choose Forget. Then put it in pairing mode and connect it again.

3. Turn Bluetooth off and back on with the switch at the top of Bluetooth settings, or restart your Mac.

4. Move closer and away from Wi-Fi routers, microwaves and USB hubs, which can drown out the signal.

5. Try pairing the device with a phone. If it won't pair with anything, the device is likely faulty and the maker can help. If no device will pair with your Mac at all, contact Apple Support, as the Mac's Bluetooth may need a repair.
