Method #3: Delete Bluetooth Preferences
- Click Go on the Finder menu and choose Go To Folder from the drop-down.
- Now type “/Library/Preferences/” (without the quotes) and hit Enter.
- Once the Finder opens up, locate the file “apple.Bluetooth.plist” and move it to Trash. Additionally, if you see a file named “com.apple.Bluetooth.plist.lockfile” delete it as well.
Note: Because you are deleting files from a system folder you may be required to authenticate with an admin username and password.
- Now, click the Apple logo on the menu bar and choose Shut Down to power down your Mac.
- Wait 2-3 minutes and turn it on.
- Click on the Bluetooth icon on the menu bar to resync your devices.
