Apple releases iOS 27, macOS Golden Gate 27 with Siri AI and Liquid Glass refinements

苹果发布 iOS 27 与 macOS Golden Gate 27，引入 Siri AI 及 Liquid Glass 界面优化

As previously announced, Apple has today released 2026’s major annual updates for its operating systems, including iOS 27, macOS 27 Golden Gate, watchOS 27, visionOS 27, and tvOS 27. Siri AI—a large language model-based and context-aware overhaul of the company’s Siri voice and text assistant—is the flagship feature across all these releases except one (tvOS). 正如之前所宣布的那样，苹果公司今日发布了 2026 年操作系统年度重大更新，包括 iOS 27、macOS 27 Golden Gate、watchOS 27、visionOS 27 以及 tvOS 27。Siri AI 是除 tvOS 外所有版本中的旗舰功能，它是对苹果 Siri 语音和文本助手的一次重大升级，基于大语言模型并具备上下文感知能力。

The new Siri can respond in kind to natural language requests to do things like explain what’s on the screen and search the user’s past personal context and history (like old emails and text messages). It can also directly interact with applications when developers have added support for that. Other new AI features include the ability to generate Shortcut automations or Safari extensions from a prompt and additional photo editing options. There’s now a dedicated Siri app, kind of similar in some respects to the classic ChatGPT or Claude apps. 全新的 Siri 能够以自然语言回应用户的请求，例如解释屏幕上的内容，或搜索用户的个人背景和历史记录（如旧邮件和短信）。当开发者添加了相关支持后，它还能直接与应用程序进行交互。其他 AI 新功能还包括通过提示词生成快捷指令自动化或 Safari 扩展，以及更多的照片编辑选项。现在还新增了一个独立的 Siri 应用，在某些方面类似于经典的 ChatGPT 或 Claude 应用。

Siri AI and other “Apple Intelligence” features are primarily driven by a handful of Apple-developed models, most of them labeled AFM 3. On-device, there’s AFM 3 Core with 3 billion parameters, and AFM 3 Core Advanced, a 20-billion-parameter model that “uses a sparse architecture, activating just 1 to 4 billion parameters at a time depending on the request.” On top of that, there are AFM 3 Cloud, ADM 3 Cloud (Image), and AFM3 Cloud Pro, more powerful models running on remote servers. Siri AI 和其他“Apple Intelligence”功能主要由几款苹果自研模型驱动，其中大多数被标记为 AFM 3。在设备端，包括拥有 30 亿参数的 AFM 3 Core，以及拥有 200 亿参数的 AFM 3 Core Advanced，后者“采用稀疏架构，根据请求每次仅激活 10 亿至 40 亿个参数”。此外，还有运行在远程服务器上、性能更强大的 AFM 3 Cloud、ADM 3 Cloud (Image) 和 AFM3 Cloud Pro 模型。

Beyond AI Across both iOS and macOS, users now have a slider to affect how transparent or opaque the “Liquid Glass” design is across the operating system. And on the macOS side especially, Apple has made numerous small design tweaks to address user feedback, which has been accumulating since Liquid Glass was introduced. There’s nothing radically new in terms of design here, but this is a much-needed polish pass. 在 AI 之外，iOS 和 macOS 的用户现在可以通过一个滑块来调节整个操作系统中“Liquid Glass”设计的透明度。特别是在 macOS 方面，苹果针对自 Liquid Glass 推出以来积累的用户反馈，进行了大量细微的设计调整。虽然在设计上没有翻天覆地的变化，但这确实是一次非常必要的打磨。

Across all the releases, but in particular macOS and also iOS, there are a bunch of quality-of-life or performance improvements. For example, macOS now supports HDR for all system UI elements and gets more robust support for a wider range of display modes for external monitors. tvOS 27, visionOS 27, and watchOS 27 are generally much more minor updates than iOS 27 or macOS 27 Golden Gate. 在所有更新版本中，尤其是 macOS 和 iOS，都包含了一系列旨在提升体验或性能的改进。例如，macOS 现在支持所有系统 UI 元素的 HDR 显示，并为外接显示器提供了更强大的显示模式支持。相比 iOS 27 和 macOS 27 Golden Gate，tvOS 27、visionOS 27 和 watchOS 27 的更新幅度相对较小。

tvOS completely lacks the new Siri AI features and instead focuses on tweaks or new features for the Podcasts and Music apps, plus the option to pick larger text sizes for the user interface. watchOS adds the Siri app and Siri AI, a new watch face, and various design updates, along with some expanded health and fitness features (like perimenopause and menopause notifications and tracking, and more accurate step counting). However, it also removes a couple little-used features, including Walkie Talkie. Finally, visionOS also gets Siri AI and the Siri app. It has a new virtual environment (Thórsmörk), improved screen recording, and small UX tweaks throughout. tvOS 完全没有包含新的 Siri AI 功能，而是专注于播客和音乐应用的调整或新功能，并增加了为用户界面选择更大字体的选项。watchOS 增加了 Siri 应用和 Siri AI、新的表盘以及各种设计更新，同时扩展了一些健康和健身功能（如围绝经期和绝经期通知与追踪，以及更准确的计步功能）。不过，它也移除了一些使用率较低的功能，包括“对讲机”。最后，visionOS 也获得了 Siri AI 和 Siri 应用，新增了虚拟环境（Thórsmörk），改进了屏幕录制，并在整个系统中进行了细微的 UX 调整。

Availability and support All these updates are available to supported devices starting today. iOS 27 supports the iPhone 11 and later, but you’ll need either an iPhone 15 Pro or an iPhone 16 or later to use Siri AI. Golden Gate requires an M-series Mac. It’s also worth noting that Golden Gate is the last version of macOS to support Rosetta, which helps Apple Silicon/M-series Macs run older Intel-based applications. After this cycle, many older unmaintained apps will stop working, but Apple did carve out an exception for older games that were developed for Intel Macs. 可用性与支持：所有这些更新从今天起向受支持的设备开放。iOS 27 支持 iPhone 11 及后续机型，但使用 Siri AI 需要 iPhone 15 Pro 或 iPhone 16 及后续机型。Golden Gate 需要 M 系列芯片的 Mac。值得注意的是，Golden Gate 是最后一个支持 Rosetta 的 macOS 版本，该技术帮助 Apple Silicon/M 系列 Mac 运行旧款基于 Intel 的应用程序。在此周期之后，许多不再维护的旧应用将停止工作，但苹果为针对 Intel Mac 开发的旧游戏保留了例外。
