Setapp Toolbox: Efficiently solve Bluetooth failures

The Setapp subscription service offers over 230 Mac and iPhone applications, including many tools for fixing Bluetooth issues. This article will use the five tools, CleanMyMac X, Quit All, App Tamer, ToothFairy and Boom 3D, all included in the Setapp subscription. Setapp also provides a large number of guides and shortcuts to improve your productivity.

Common Bluetooth problems and solutions:

1. The Bluetooth Preferences panel cannot load:

After upgrading macOS, the Bluetooth preferences window may not be displayed. You can click the Bluetooth icon in the menu bar to view connected devices, but you cannot pair new devices. The current effective solution is to debug Bluetooth or reset the Bluetooth module.

You can debug Bluetooth by holding down Shift ⇧ Option (或Alt) ⌥ on your keyboard and clicking on the Bluetooth icon. This adds the Debug option (also known as the Reset Bluetooth Module) in the Bluetooth drop-down menu. But for some users (including me), the "Debug" option may not appear on Monterey.

Solution: Use the terminal to reset Bluetooth:

1. Open the terminal and paste the command: sudo pkill bluetoothd
2. Click Enter
3. Enter the administrator password
4. Wait for five seconds, then set up Bluetooth and check if the Preferences panel is working properly.

2. Bluetooth cannot detect the device:

Even if the Preferences panel works properly, Bluetooth may not see the device you are trying to connect to. In this case, reset the Bluetooth settings just like the Reset Preferences panel. Hold down Shift ⇧ Option (或Alt) ⌥ , click on the Bluetooth icon, and select the "Reset Bluetooth Module" option. Or use the terminal commands mentioned above.

Tip: Use AirBuddy as an alternative tool to connect to Bluetooth devices to avoid tedious troubleshooting steps.

AirBuddy provides a simple interface, iOS-like "bubble" pairing screen, connecting Apple and non-Apple devices with just a click.

1. Make sure your headset is in discoverable and close to your Mac (if it is AirPods, open the lid)
2. Click "Connection" on the pop-up screen
3. Click the AirBuddy menu bar icon at any time to check the connection status.

3. Bluetooth cannot display:

Some users report that Bluetooth is completely unavailable after macOS updates. The "Bluetooth Unavailable" error will pop up when you try to connect to a new device. A quick fix is ​​to use ToothFairy instead of the Bluetooth menu. After that, you can try to fix Bluetooth by resetting the Bluetooth plist file.

1. Turn off Bluetooth-interference applications
2. Open Finder, hold down the Option key, and click前往> 资源库> Preferences
3. Find the plist file with "Bluetooth" in the name and delete it
4. Restart your Mac and try to reconnect to your Bluetooth device.

How to determine which application interferes with Bluetooth? Use Quit All to close all applications (including background applications) in one click, and then delete the plist file.

Tip: Use App Tamer to detect applications that take up too much CPU and interfere with Mac performance.

4. Bluetooth headsets cannot display:

If a specific AirPods or wireless headset is not displayed in the Bluetooth menu, try setting it up using ToothFairy.

Alternatively, you can try disconnecting and pair your headset with your Mac again:

1. Open Mac's System Preferences > Bluetooth
2. Turn on Bluetooth and make sure it is in discoverable state
3. Put the headset close to the Mac
4. Use the reset button on the headset to disconnect the headset from all devices (for AirPods, press and hold the button on the box until you see a white light)
5. In the Mac's device list, select your headset and click Connect.

5. The power of the Bluetooth headset cannot be displayed:

Reset Bluetooth, or use the Batteries app to track battery power.

6. Bluetooth microphone problem:

Adjust output and input sound settings in system preferences, or use Boom 3D.

7. Bluetooth speaker problem:

Check the playback device in the sound settings of the system preferences, or try the following:

• Run maintenance scripts (CleanMyMac X)
• Reset SMC (System Management Controller) (Intel Mac: Press and hold Control (或Ctrl) ⌃ Option (或Alt) ⌥ Shift ⇧ 电源按钮10 秒; M1 Mac: Just restart)

8. Bluetooth randomly disconnected:

• Hold Option (或Alt) ⌥ Shift ⇧ and click on the Bluetooth icon, then click "Remove All Devices".
• Reset Bluetooth.
• Exit the application using the Quit All app.
• Reset SMC.
• Connect to Bluetooth devices using ToothFairy.
