On September 14, 2026, Apple officially released iOS 27, alongside the rest of this year’s operating systems: iPadOS 27, watchOS 27, tvOS 27, and macOS 27 «Golden Gate.» It’s one of Apple’s most ambitious software updates in years, headlined by a completely rebuilt AI assistant, visual refinements to the Liquid Glass design, and performance improvements that should be noticeable even on older iPhone models.
Here’s everything this new version brings, which devices support it, and how to install it.
Release date and availability
The update was officially unveiled on June 8, 2026 at WWDC, and after several months of developer and public betas, the final version arrived on Monday, September 14, 2026, coinciding with the announcement of the new iPhone lineup. Since it’s a simultaneous global rollout, the download may take longer than usual during the first few hours due to server load.
You can check for the update on your device under Settings > General > Software Update.
Siri AI: the biggest change in iOS 27
The most talked-about feature of this release is, without question, Siri AI, a fully redesigned version of Apple’s assistant. After two years of unfulfilled promises, Apple rebuilt Siri from the ground up using Google’s Gemini technology — with one important caveat: Siri AI runs privately on the iPhone itself and, when it needs extra processing power, relies on Apple’s Private Cloud Compute rather than Google’s servers.
Key capabilities include:
- Natural-language conversations with context retained across follow-up questions.
- A dedicated app, similar to ChatGPT, that saves conversation history and lets you attach photos or documents.
- The ability to type to Siri directly by swiping down from the top of the screen.
- Camera integration to answer questions about what you’re looking at, check nutritional information, or split a bill.
- In-app actions, such as updating multiple passwords at once through agentic AI.
For now, Siri AI is launching in English only; Spanish and other languages will roll out in the coming weeks. Its rollout is also temporarily paused in the European Union and China while Apple works through regional compliance requirements.
Liquid Glass, taken a step further
The Liquid Glass design language, introduced last year in iOS 26, gets refined in this release. The main improvements are:
- A new slider in Settings that lets you adjust interface transparency, from fully translucent glass to a more opaque, tinted look for better readability.
- App icons with more depth and sharper highlights.
- Higher overall contrast for easier reading of text and controls.
- Support for larger widget sizes on the home screen.
Performance: a noticeably faster system
Beyond AI, Apple focused heavily on speed and stability. According to the company, iOS 27 delivers:
- Apps that open up to 30% faster.
- Photos that load into your library up to 70% faster.
- AirDrop transfers up to 80% faster.
- A rebuilt search foundation that improves Spotlight, Photos, and Mail.
- Optimizations to the keyboard, Bluetooth, CarPlay, and automatic switching between Wi-Fi and cellular data.
These improvements are designed to be noticeable even on iPhone models that are several years old, not just the newest hardware.
Photos, Safari, and other notable additions
The Photos app gains several AI-powered editing tools, including:
- Spatial Reframing, which recomposes a photo by virtually changing the camera’s position.
- Extend, which expands an image’s borders using generative fill.
- An object eraser (Clean Up) with both a fast mode and a high-quality mode.
In Safari, tabs are now grouped automatically by topic, and the browser can alert you to price or availability changes on pages you visit. You can also create extensions and shortcuts simply by describing them in natural language.
Parental controls have also been strengthened, with a new «Ask to Browse» feature (requiring approval for websites), filters for violent content in Messages, and child accounts linked to an adult’s Apple account.
macOS 27 Golden Gate: the end of the Intel era
The Mac version, named macOS 27 «Golden Gate,» shares the same Siri AI and Liquid Glass updates, but with one important catch: it’s only available on Apple Silicon Macs. Intel-based Macs are excluded from this update, though they’ll continue receiving security patches through macOS 26 Tahoe for roughly three more years.
Compatible devices
- iOS 27: available on every iPhone model that could already run iOS 26.
- iPadOS 27: compatible with most recent iPads, though some older models are left out.
- watchOS 27: drops support for several older Apple Watch models.
- macOS 27 Golden Gate: exclusive to Apple Silicon Macs.
To get the most out of Siri AI’s advanced features, Apple recommends an iPhone 15 Pro or later, since these capabilities require more on-device processing power.
How to update your device
- Back up your iPhone, iPad, or Mac before updating.
- Connect to a stable Wi-Fi network and, if possible, keep your device charging.
- Go to Settings > General > Software Update (or System Settings on Mac).
- Download and install the update for your device.
- Be patient: as a global release, downloads may take longer than usual during the first few hours.
Conclusion
iOS 27 and the rest of the operating systems in this release — internally referred to as «Platform 27» — mark one of Apple’s biggest software leaps in years, with Siri AI as the clear centerpiece. While some AI features are still in beta and will gradually expand to more languages and regions, the performance gains and refined Liquid Glass design are already available from day one to every compatible user.
