- Click the Apple logo in the upper left-hand corner of the screen.
- Click System Preferences.
- Click Bluetooth.
- Click Turn On Bluetooth.
- When Bluetooth is on, your Mac will say Bluetooth: On.
Why this works:
Bluetooth is the technology that allows your Mac to wirelessly connect to other devices like headphones and keyboards. Bluetooth needs to be turned on before you can connect your Mac to Bluetooth devices.
Pro tip:
- You can also toggle Bluetooth on or off on your Mac by clicking the Bluetooth icon in the menu bar and turning on the switch next to Bluetooth.
