Bluetooth Pairing and Troubleshooting
How to pair Bluetooth devices, fix failed connections, and troubleshoot common pairing issues
Bluetooth pairing fails more often than it should. The usual culprits are the device not being in pairing mode, an old pairing that needs to be removed first, or a driver issue. Work through these steps in order — most problems are fixed by removing the device and pairing fresh.
- Open System Settings > Bluetooth
- Make sure Bluetooth is toggled on
- Put your device into pairing mode — this varies by device, but usually means holding the power button or a dedicated pairing button until a light flashes (check the device's manual if unsure)
- Your device should appear under Nearby Devices — click Connect next to it
- If the device asks for a PIN, enter it (common PINs are
0000or1234) - If the device does not appear, turn Bluetooth off, wait 10 seconds, turn it back on, and try again
- If the device was previously paired but won't reconnect, click the info (i) button next to it and select Forget This Device, then pair it again from scratch
- For a deeper reset, try turning Bluetooth off in System Settings > Bluetooth, restarting your Mac, then turning Bluetooth back on. On older macOS versions (Monterey and earlier), you can hold Shift + Option and click the Bluetooth icon in the menu bar for a Reset Bluetooth module option
- If Bluetooth issues persist after a macOS update, check System Settings > General > Software Update for a follow-up patch — Bluetooth regressions are sometimes fixed in point releases
AirPods and Beats headphones pair automatically if they are signed into the same Apple Account as your Mac. Just open the lid near your Mac and follow the on-screen prompt.
Frequently Asked Questions
Why won't my Bluetooth device pair?▾
The most common reasons are: the device isn't actually in pairing mode (just being powered on is not enough), there's a stale pairing that needs to be removed first, or the device is still connected to another computer or phone. Remove the device from all previously paired devices, put it in pairing mode fresh, and try again.
Can I connect multiple Bluetooth devices at the same time?▾
Yes. Most computers can connect several Bluetooth devices simultaneously — a mouse, keyboard, and headphones at once is common. However, connecting two Bluetooth audio output devices at the same time doesn't work well on most systems because the Bluetooth radio has to split bandwidth, which causes audio quality and latency issues.
Why does Bluetooth audio quality drop during calls or when using the microphone?▾
Bluetooth headphones use different codecs depending on whether they're in listening mode or call mode. When only playing audio, they use a high-quality codec (AAC, aptX, or SBC at high bitrate). When the microphone activates for a call, many devices switch to the HFP/HSP profile, which drops to a much lower quality mono codec. This is a Bluetooth protocol limitation, not a bug. Using a separate wired or USB microphone while keeping Bluetooth for audio output avoids this.
