Apple has just released the fourth beta of macOS Sierra, the newest operating system designed for the Mac, to developers. macOS Sierra beta 4 comes two weeks after the release of the third beta and almost two months after the software was first unveiled at Apple’s 2016 Worldwide Developers Conference.
macOS Sierra offers a plethora of new features. That includes the ability to use Apple Pay, the company’s mobile payment option, from within Safari for partners that include Gilt, and other major brands. With it, users will be able to authenticate purchases on their desktop by using Touch ID on their iPhone.
macOS offers other new Continuity features, including the ability to unlock your MacBook –avoiding the part where you input your password– by having your Apple Watch on your wrist. Another big addition to the software is Picture-in-Picture support, which will let users pop out a video and continue to watch it while they navigate other apps behind it. The picture can be resized, moved around, and it will stay on the top of other apps as the user moves from one virtual desktop to another.
The biggest new addition for macOS Sierra is Siri, which lets users ask the digital personal assistant to do a variety of things, like find files, contacts, and use more complex voice queries to find specific elements on their computer from specific dates or from other people. Siri can also play music from Apple Music, send messages, and much more.
The fourth developer beta for macOS Sierra is available right now on Apple’s dedicated developers page, right here. If you’re signed up as a developer, you can download the new pre-release software now. It is also available as an over-the-air (OTA) update on machines already running the first developer beta.
Apple will release iOS 10, macOS Sierra, tvOS 10 and watchOS 3 this fall.
