- Copy the Bluetooth. plist files as a backup to your desktop (for security or possible restoration).
- Select the Bluetooth. plist files and move them to Trash.
After removing the Bluetooth .plis files, you need to restart your Mac. After a restart, your Mac machine will recreate new Bluetooth .plist files. You can check if your Bluetooth works well now.
