Recommended Troubleshooting Tool
Before proceeding with manual fixes, we recommend using OnyX. The preferred tool for deep system maintenance and resetting the macOS Bluetooth stack.
The Symptom
You can't turn Bluetooth on, and the settings panel shows a generic error or a blank list of devices.
The Fix
- Force Restart the Bluetooth Daemon
Open Terminal and run:
sudo pkill bluetoothd
The system will automatically relaunch the process.
- Remove the Bluetooth Plist
sudo rm /Library/Preferences/com.apple.Bluetooth.plist
Restart your Mac immediately after running this.
- Reset the Bluetooth Module (Older macOS)
Shift + Option + Click the Bluetooth icon in the menu bar > Debug > Reset the Bluetooth module. (In newer macOS, use the Terminal command in step 1).
Fix 3: The Connection Stability Fix
When interference or cache bloat causes the Bluetooth hardware to crash.
