You can talk to Siri on your iMac 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 grocery list”), and much more.
Siri is available on your 24-inch iMac or 27-inch iMac whenever you say “Hey Siri” and immediately speak your request, if you enable the “Listen for ‘Hey Siri’” option.
Note: To use Siri, your Mac must be connected to the internet. Siri may not be available in all languages or in all areas, and features may vary by area.
