How to downgrade macOS Sierra
The macOS Sierra Apple

Apple has released the seventh beta for the macOS Sierra, which is the company's upcoming OS version for MacBooks along with the macOS Sierra Public Beta 6. The latest beta release comes days after Apple released the iOS 10 beta 7 for iPhones, iPads and iPod touch devices.

The build carries No 16A304a and both developers and public beta testers can download the update through the Mac App Store. Developers can also download the beta from the Apple Developer Centre.

The macOS Sierra is a major update for MacBooks that among other features brings Siri to the Mac for the first time. The OS also has a new Safari improvement for watching videos, a feature that has existed on select iPads for a while. Besides, the new OS features an "Auto Unlock" option through which an Apple Watch user can unlock his Mac from the watch itself.

Apple Pay is slated to hit the MacBook post the macOS Sierra update, with facility to authenticate payments through an iPhone or Apple Watch. Messages on macOS Sierra will get a new interface with rich links for previewing web content.

The Photos app for MacBooks has been overhauled with new features that take advantage of computer vision to recognise people, places and more. Just like Google Photos, the overhauled app from Apple will curate a user's past photos into collections via a new tab called "Memories."

The final and stable version of the Sierra is expected to be released sometime next month at an Apple event, where the company is also slated to release the iPhone 7 and iOS 10 among others.
