Siri on your Mac
You can talk to Siri on your MacBook Pro and use your voice for many tasks. For example, you can find files, schedule meetings, change preferences, get answers, send messages, place calls, and add items to your calendar. Siri can give you directions (“How do I get home from here?”), provide information (“How high is Mount Whitney?”), perform basic tasks (“Create a new list called Groceries”), and much more.
Note: Siri may not be available in all languages or in all areas, and features may vary by area.
Enable Siri. Click the Siri icon 
in the menu bar or in the Dock, then click Enable when prompted. If you enabled Siri during setup, clicking the icon opens Siri. Or click the System Preferences icon 
in the Dock, click Siri, then select Enable Ask Siri. You can set other preferences in the pane, such as Language and whether to show Siri in the menu bar.
On your MacBook Pro with the Touch Bar (mid-2018 model or later), you’ll see additional options in the Siri preferences pane, including “Listen for ‘Hey Siri’” and “Allow Siri when locked.”
Note: To use Siri, your MacBook Pro must be connected to the internet.
Speak to Siri. Click Siri in the menu bar or the Dock and start speaking. Or press and hold the Command key and the Space bar, and speak to Siri.
Hey Siri. On your MacBook Pro with the Touch Bar (mid-2018 model or later), you can simply say “Hey Siri” to get responses to your requests. To enable this feature in the Siri pane of System Preferences, click “Listen for ‘Hey Siri’,” then speak several Siri commands when prompted. You can also tap the Siri button in the Control Strip to open Siri.
For convenience, “Hey Siri” doesn’t respond when the lid to your MacBook Pro is closed. If the lid is closed and connected to an external display, you can still invoke Siri from the icon in the menu bar or Dock.
Tip: To learn about more ways you can use Siri, ask “What can you do?” at any time, or click the Help button 
.
Play some music. Just say, “Play some music,” and Siri does the rest. You can even tell Siri, “Play the top song from March 1991.”
Find and open files. Ask Siri to find files and open them right from the Siri window. You can ask by file name or by description. For example, “Show me files Ursula sent,” or “Open the spreadsheet I created last night.”
Drag and drop. Drag and drop images and locations from the Siri window into an email, text message, or document. You can also copy and paste text.
Pin a result. Save Siri results from sporting events, Reminders, Clock, Stocks, Notes, Finder, and general knowledge (Wikipedia, for example) to the Today view in Notifications. Click the plus sign 
in the top right of a Siri result to pin it to the Today view. To see it later, click the Notification Center icon 
, then click Today. If you’re checking a sports score, for example, results stay up to date.
Change the voice. Click the System Preferences icon in the Dock, click Siri, then choose an option from the Siri Voice menu.
Throughout this guide, you’ll find suggestions for things you can ask Siri—they look like this:
Ask Siri. Say something like:
“Open the Keynote presentation I was working on last night”
“What time is it in Paris?”
