Apple Seeds Fifth Beta of macOS Sierra to Developers [Update: PB4 Now Available for Public Beta Testers]

Apple today released the fifth beta of macOS Sierra, the newest operating system designed for the Mac, to developers. macOS Sierra beta 5 comes one week after the release of the fourth beta and approximately two months after the software was first unveiled at Apple's 2016 Worldwide Developers Conference.

Developers can download today's beta update through the Software Update mechanism in the Mac App Store or through the Apple Developer Center.

macOS Sierra is a major update that brings Siri to the Mac for the first time, allowing users to conduct voice searches to quickly find files, look up information, and more. New Continuity features offer an "Auto Unlock" option for unlocking a Mac with an Apple Watch and a "Universal Clipboard" for copying text on one Apple device and pasting it on another.

Deeper iCloud integration allows files stored on the desktop or the Documents folder of a Mac to be accessed on all of a user's devices, and Photos features deep learning algorithms for improved facial, object, and scene recognition. There's also a Memories feature for displaying photo collections, and Messages has rich links, bigger emoji, and "Tapback" response options.

Apple Pay is coming to the web in macOS Sierra, with payments authenticated through an iPhone or Apple Watch, and new features like multiple tabs, Picture in Picture multitasking, optimized storage, and revamped emoji are also available.


During the beta testing period, Apple tweaks and refine the features introduced in macOS Sierra to prepare it for public release. In macOS Sierra beta 4, Apple introduced new emoji promoting gender equality and introduced a new look for many existing emoji with new textures and design tweaks. Any changes found in the fifth beta will be listed below.

macOS Sierra is currently available to developers and public beta testers, and it will see a wider public release this fall. For full details on all of the new features included in macOS Sierra, make sure to check out our macOS Sierra roundup.

Update: Apple has also seeded macOS Sierra public beta 4 to public beta testers. It is identical to the 5th developer beta.

Have they finally given the option to change the default behaviour of the green button to expand to maximum instead of going fullscreen? I have 100 people in my office building and nobody uses fullscreen on a laptop or desktop, they all hate it. There's NO point in fullscreen on a large screen.

And what about a proper cut/paste command (ctl+x / ctrl+v) in Finder? Is System Integrity Protection still screwing over developers like TotalFinder?

Couldn't disagree more. Logic Pro full screen. Safari on another. iTunes on another. Guitar Pro on the next. 4-finger swipe and I'm immediately on the other one I want. Smooth as silk.

I think full screen is perfect if you're working with multiple desktops. Especially when you're using content-rich creative applications like FCPX and Photoshop, you really need all the space you can get.

I like fullscreen, but I have another issue with it - I hate that the menu bar disappears. I'd love an option for the menu bar to be "always on". For crying out loud - many of us have have enormous size monitors, hiding the menu bar gives negligible vertical pixels, but so much annoyance when you just want to glance the time, change some setting fast etc.

I still don't understand their icon design... an icon should be symbolic, easy to identify in black-and-white. The Siri icon is not that. Why not a simple microphone? Do they think that people will confuse it with something else?

While I'd be all for an option to change the default behavior, I have to disagree with you that there is no point in full screen. I have a 27" 4K monitor, and I run 3-5 full screens always. My code editor runs in one screen, I'm running full screen browsers w/ debugging tools in 1-3 other screens, and I'll often have tools like Sketch using another full screen.

I'm not sure what your line of work is, but just looking around the office right now here I see several people using their Macs in full-screen.

It makes more sense to have indeed something like Ctrl+X / Ctrl+V.
Ewww, Ctrl+V to paste? Every time I'm in BootCamp, I feel dirty doing that.
