Activate Siri
Note: You must be connected to the internet to use Siri.
To activate Siri on your Mac, do any of the following:
Press and hold if available in the row of function keys; otherwise, use the keyboard shortcut as specified in Siri & Spotlight settings.
Click Siri in the menu bar. If it’s not shown, you can add it using Control Center settings.
Tap Siri in the Touch Bar (if your Mac has a Touch Bar).
Say “Hey Siri” (if enabled in Siri & Spotlight settings; this option is only available when supported by your Mac, display, or headphones).
To verify that you can use “Hey Siri” on your device, see the Apple Support article Devices that support “Hey Siri.”
