Hi,
If Bluetooth repeatedly turns off on your MacBook Air running macOS Monterey 12.7.6, try the following troubleshooting steps:
1. Reset the Bluetooth Module:
- Option 1 (Basic):
- Turn Bluetooth off and then on again from the Bluetooth icon in the menu bar or System Settings.
- Option 2 (Advanced):
- Hold the Shift and Option keys while clicking the Bluetooth icon in the menu bar, then select "Reset the Bluetooth module".
- Option 3 (Terminal):
- Open Terminal and run the command sudo killall bluetoothd. You'll need to enter your Mac password. This restarts the Bluetooth daemon.
2. Delete the Bluetooth .plist File:
- Finder: Open Finder, go to Library > Preferences, and delete the com.apple.bluetooth.plist file.
- Restart: Restart your Mac. A new .plist file will be generated.
3. Reset SMC:
- Laptop: Turn off your Mac, then hold the Control, Option, and Shift keys while pressing the power button. Release all keys.
4. Check for Software Updates:
- Make sure your macOS is up to date, as updates can sometimes resolve Bluetooth issues.
5. Disable Bluetooth while the Mac is Sleeping:
- If your Bluetooth devices keep disconnecting when your Mac is asleep, consider using a free app like Bluesnooze to turn off Bluetooth when your Mac sleeps and back on when it wakes up.
6. Check for Interference:
- External Devices:
- Disconnect any external devices, non-primary monitors, or hard drives to see if they are causing interference.
- Wireless Devices:
- Ensure there are no other wireless devices (like microwaves or cordless phones) causing interference.
7. Check Device Compatibility:
- If the issue persists, try connecting to different Bluetooth devices to see if the problem is specific to one device.
8. Consider a Bluetooth Dongle:
- If the built-in Bluetooth is not working, you could try a USB Bluetooth dongle as a temporary solution.
