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.
