Turn Bluetooth on or off on Mac
There may be situations when you need to turn Bluetooth® off.
Note: If Bluetooth is turned off, features such as Continuity, Instant Hotspot, and Handoff may not work between your Mac and other devices.
On your Mac, choose Apple menu > System Settings, then click Bluetooth in the sidebar. (You may need to scroll down.)
Click to turn Bluetooth on or off.
If you’re using an external USB Bluetooth adapter, the option may not appear in Bluetooth settings. Try unplugging the adapter to turn off Bluetooth.
Note: You can’t turn Bluetooth off if you’re using a Mac desktop computer and you only have a wireless mouse, keyboard, or trackpad connected using Bluetooth.
You can also turn Bluetooth on or off by clicking the Bluetooth status icon in the menu bar and clicking the switch. If the icon isn’t shown in the menu bar, you can add it using Control Center settings.
