Apple today pushed a second beta of macOS Sierra following the original developer-only preview of the desktop operating system that was made available following the June 13 WWDC keynote. Members of the Apple Developer Program can install macOS Sierra beta 2 (build number “16A239j”) on their computers running a prior beta through the Software Update mechanism.

We’ll be updating this article with any changes discovered in macOS Sierra beta 2 as we encounter them.

Other developer updates

Apple today released the following OS-related updates for developers:

macOS Sierra highlights

In addition to rebranding OS X as macOS, the upcoming software update brings a bunch new features to the Mac, including deeper integration with iOS and expanded Continuity features.

For starters, Siri is now available on the Mac to help you do the things you do every day on your desktop using the power of your voice. Expanded integration with iCloud makes your Mac’s Desktop and Documents folder available on your iPhone, iPad and iPod touch via iCloud Drive.

Universal Clipboard works between iOS and macOS, allowing you to copy text, images, photos and video from one Apple device and paste it in another. Sierra also includes Safari 10 with support for Picture-in-Picture, native App Extensions and Apple Pay on websites.

Like iOS 10, macOS Sierra packs in an enhanced Photos app with a new Memories feature that uses advanced facial and objet recognition, and more.

macOS Sierra availability

macOS Sierra is available as a developer-only preview to all members of the Apple Developer Program. The operating system will be available to public beta testers via the Apple Beta Software Program in July ahead of its general availability this fall.

macOS Sierra will support a smaller number of Macs than previous editions. Supported computer models include late-2009 and later MacBooks and iMacs, and 2010-and-later MacBook Airs, MacBook Pros, Mac Minis and Mac Pros.

Macs manufactured before 2008 won’t be supported.

    is anybody having iCloud trouble

    • Agneev Mukherjee

      Nope as long as you have at least 5MB iCloud storage left..

  • [RECON1]

    9to5Mac posted an article stating that the Auto Unlock feature is now enabled.

    • Agneev Mukherjee

      They’ll write an article about that after they write about the changes in macOS Sierra beta 2, which they haven’t done so far much to my disappointment.

  • I still can’t get Universal Clipboard to work at all; (I have a 2011 iMac) But its not dependent on the chipset required for Handoff; it just uses iCloud; no?
