OS X El Capitan: Turn Bluetooth on or off
Turn off Bluetooth when you’re in places where radio communication may be prohibited, such as in an airplane or a hospital.
Click the Bluetooth status icon in the menu bar and choose Turn Bluetooth On or Turn Bluetooth Off.
If the Bluetooth status menu isn’t visible, choose Apple menu > System Preferences, click Bluetooth, then select “Show Bluetooth in menu bar.”
You can also turn Bluetooth on or off in Bluetooth preferences. If you’re using an external USB Bluetooth adapter, Turn Bluetooth On or Turn Bluetooth Off may not appear in Bluetooth preferences. If it doesn’t, unplug the adapter to turn off Bluetooth.
