Apple's iOS 27 update rebuilds the Search system it first previewed at WWDC in June, prompting an 'Optimizing Search and Siri' banner in Settings after installation. This reindexing process scans and reorganizes metadata across the device so Spotlight and Siri can return faster, more accurate results, and it can take anywhere from a few hours to several days to complete.
Apple has released iOS 27, extending general software updates to devices as old as the iPhone 11. However, the headline feature—an AI-enhanced version of Siri—is restricted to the iPhone 15 Pro and newer models, likely due to processing demands of on-device AI.
A hands-on review of iOS 27 reports that Apple's revamped Siri, now built on Google's Gemini models, can handle multistep tasks like drafting messages, summarizing on-screen content, and answering complex questions with far greater accuracy than before. The reviewer, who had largely stopped using Siri, says the assistant now understands context from apps, messages, and emails, and comes with a new logo and animation.
Apple has begun rolling out watchOS 27, which requires iOS 27 to install via the iPhone Watch app. The update brings a fully capable Siri AI assistant matching the version on iPhone and Mac, a new Siri watch face, a Tap gesture, and additional health features, along with general performance improvements. Notably, the update drops support for several older models including the first-generation Apple Watch Ultra, Series 6, 7, 8, and the second-generation SE.
Apple has begun rolling out visionOS 27 to all Vision Pro headsets, including both the original M2 model and the newer M5 version. The update introduces an AI-enhanced Siri and standalone Siri app, a new Thórsmörk Environment, the ability to convert panoramas into spatial scenes, and Visual Intelligence for asking Siri about objects in view. Other additions include extra-small widgets, sharper screen recording, curved windows, eye-based notification expansion, a redesigned Control Center, and accessibility tools like wheelchair control and Vehicle Motion Cues.
Apple's macOS 27 update brings a redesigned Siri that can view whatever is on screen, answer questions about it, and summarize or compare content using new Visual Intelligence tools. Users can pull an active window into Siri's context with Command+Shift+Space or select a specific screen region with Command+Shift+6 for targeted actions like contact lookup or location search. Spotlight Search also gains AI-powered web answers plus filtered search across apps, files, actions, and clipboard history.
Apple has launched macOS 27 Golden Gate to the public after a lengthy beta period, bringing a redesigned Siri built on Apple Intelligence, further refinements to the Liquid Glass visual style, new Safari features, and various performance upgrades. The update includes a customizable transparency slider for Liquid Glass, redesigned app icons with added depth, and reworked traffic light window controls with a bouncy animation.
Apple has released iPadOS 27, its latest major iPad software update, headlined by a smarter, more personal Siri accessible through a dedicated app, screen swipe, or voice commands. The update also brings deeper Spotlight integration, Mac-inspired interface tweaks like a persistent menu bar, refreshed system apps, and expanded parental controls. Five older iPad models, including the iPad mini 5 and iPad Air 3, no longer support the new software.
Apple has released iOS 27 to all eligible iPhones after a summer beta period, adding a redesigned conversational Siri assistant, new Apple Intelligence tools, and a slider to adjust the Liquid Glass interface's transparency. The update also includes performance gains such as faster app launches, quicker photo loading, and improved AirDrop speeds.
Fashion discovery app Daydream rolled out two features built on Apple's iOS 27 developer tools: one that scans outfit photos saved in a user's camera roll to find matching or similar items from its roughly 3 million product catalog, and another that lets users search Daydream's inventory by voice or text through Siri without opening the app. Both features require an iPhone running iOS 27 with Siri AI enabled and the free Daydream app installed.
MacStories' Federico Viticci published his annual in-depth iOS review, this time covering iOS 27, saying the update is less flashy than last year's but still shows Apple 'sweating the details.' He gave particular attention to Siri AI, describing it as a smarter, more capable assistant that excels at quick, one-off tasks rather than agentic, multi-step work.
Flexibits released Fantastical 4.2 and Cardhop 2.5 alongside Apple's iOS 27 and macOS 27 Golden Gate launch. Fantastical now integrates with Siri, letting users check schedules or move meetings by voice, and both apps gain larger widget sizes plus a refreshed Liquid Glass look on Mac.
