macOS 27 Golden Gate brings a more intelligent, customizable, and capable Mac experience—with a refined Liquid Glass design, a smarter Siri, powerful Apple Intelligence features, and meaningful improvements across the system.
A more personal interface
Customize the look and feel of Liquid Glass with a new transparency slider that lets you choose between a more translucent or opaque appearance. macOS 27 also introduces visual refinements inspired by iOS 27 and iPadOS 27, along with improved window placement, HDR support, and expanded high-resolution and high-refresh-rate options for external displays.
A smarter Siri
The all-new Siri is deeply integrated throughout macOS and available in its own dedicated app. Powered by Apple Intelligence and Google Gemini, Siri can use on-device indexing to understand your personal information and help you find, organize, and act on it more naturally.
Siri is also integrated into Spotlight, giving you faster access to information, actions, and personalized suggestions.

Installation instructions
A PKG file is an installation package for macOS, containing the operating system installer application. It allows you to update the system directly from your current macOS or create bootable media for a clean installation via Terminal. This is convenient because it doesn’t require a second Mac and simplifies the update process.
