Reaching the Release Candidate stage typically means Apple is polishing performance and squashing bugs rather than adding features, so this build offers the clearest preview of what millions of Mac users will get at launch. The update's heavy AI focus, including revamped Siri and natural-language Shortcuts creation, shows Apple accelerating its push to integrate generative AI across macOS.
- macOS 27 RC build 26A5428 is now available to developers and public testers via System Settings.
- Key changes include redesigned window controls, a new Siri app, AI-driven Shortcuts, and a Safari extension builder.
