The handy features of Siri on i OS are now on your Mac, along with brand-new ways to help you with the things you do every day on your desktop. So you can be working on one thing, like finishing up a document, and ask Siri to send a message to your coworker saying it’s on the way — without stopping what you’re doing. Everything stays up to date — so you always know where to find game times, trending topics, or important documents. Then drag results right to a window on your desktop.
Ask Siri to search for the documents you opened this week, then refine your results to just the ones with the word “annual” in the title.
