When Apple runs through its operating system announcements at WWDC, the OS X part of the show is pretty much the only instance when the company spends any time talking about a product name.

- Hey what's going on tech fans, welcome back to yet another video. Today we are installing macOS Sierra Developer Preview 1 on our Hackintoshes.
- bMacOS 10.12 Sierra Developer Preview 4.68 GB/b/center Description: This MacOS is primarily intended for developers. It is preliminary and is not available on the installation media.
- Update July 5, 2017: Apple has just released macOS Sierra 10.12.6 beta 6 for developers. If you already have the macOS Sierra beta installed, head to Mac App Store Updates and download away. If you've been waiting for beta 6 to start testing macOS 10.12.6, keep reading and we'll walk you through the setup!
The Mac has long since ceased to be Apple's most important product, but the company has kept up the tradition of slapping a secondary name on each OS release, something separate from the version number and the 'OS X' or 'Mac OS X' branding. Often, those names are used to set expectations about the release. Snow Leopard is a refinement of Leopard. Mountain Lion is a refinement of Lion. El Capitan is a refinement of Yosemite.
It's tempting to read the 'macOS' rebranding as some grand statement about the Mac, but, truth be told, 'Sierra' is more indicative of what we're getting. The name comes from a mountain range that encompasses Yosemite and El Capitan rather than moving away from them. It's another year of building on Yosemite's foundation, another year of incremental change, and another year of over-saturated mountain wallpapers.

Like El Capitan before it, Sierra focuses on a few marquee features, a couple of under-the-hood changes, a smattering of smaller tweaks, and one or two signposts pointing toward future development. It's the next release of OS X, new name or not. And we've spent a week with the first developer beta to dig into some of the new features ahead of the public beta in July and the public release in the fall.
The full review will dive deeper into most of the topics covered here, and will also feature more extensive comments on general stability and performance—this is an early developer beta, and things are going to be broken. Many of the things we talk about today could also be added, tweaked, or removed between now and the 'golden master' build in the fall. With all of that in mind, let's dive in.

macOS Monterey delivers powerful new user features and key technologies that help you build apps that bring users together. SharePlay provides easy ways to build all-new shared experiences, whether you’re creating a streaming app that offers shared playback or a collaborative design tool that enables simultaneous edits by users around the world. Games and pro apps take on a new dimension with powerful new features in Metal. And Object Capture in RealityKit helps you create 3D models from photos in record time.
SharePlay
SharePlay offers a new way for people to share your app. Media streaming apps can let users share content through the new Group Activities API with full-fidelity video and all syncing handled by the system. And for shared experiences beyond media streaming, the GroupSessionMessenger API offers a secure data channel that syncs information between multiple instances of your apps across multiple users.
Metal
This framework provides a platform-optimized, low-overhead API that lets you develop the latest 3D pro applications and amazing games using a rich shading language with tight integration between graphics and compute programs. New features include enhanced graphics and compute integration, function stitching, updates to Ray Tracing, GPU-accelerated ML training, and more.
Shortcuts
The power of Shortcuts is coming to macOS, so the capabilities of your app can be multiplied by exposing them as building blocks called actions. You can build Shortcuts actions on macOS whether your app is built with Mac Catalyst or AppKit, and your app can even run shortcuts itself.
Object Capture
Turn a series of 2D images from your iPhone or iPad into a photo-realistic 3D object that’s optimized for AR using Object Capture in RealityKit 2. This new macOS API gives you access to state-of-the-art photogrammetry software, so you can make unique 3D models with no 3D modeling expertise required.
Machine Learning
Build dynamic app features that leverage Create ML APIs to train models directly from user input or on-device behavior, allowing you to provide personalized and adaptive experiences while preserving user privacy. You can also take advantage of new templates and training capabilities, APls for Vision and Natural languages, and more.
ShazamKit
Enrich your app experience with audio recognition. Match music to the millions of songs in Shazam’s vast catalog or make any prerecorded audio recognizable by building your own custom catalog using audio from video, podcasts, and more.
TestFlight
Later this year, you’ll be able to invite testers to try out beta versions of your Mac apps and provide valuable feedback with TestFlight. You can invite up to 10,000 testers using just their email address or by sharing a public link.
