Less than a month after its unveiling at Apple’s Worldwide Developers Conference in June, macOS Sierra arrived today for beta testers who have signed up to try Apple’s new desktop operating system. This is the third year in a row Apple has offered a public beta of an upcoming desktop OS.
This year the Mac platform gets some significant enhancements, with Sierra bringing one notable feature that promises to change how users interact with their Mac. After teasing users in 2015 with a revamped Spotlight in OS X El Capitan that understood sophisticated requests, Sierra finally brings Siri to the Mac.
