Apple unveiled its next major iOS update, but not every device will be able to get it.

Here’s the complete list of supported iPhones, iPads, Apple Watches and Macs that will get iOS 27, iPadOS 27, watchOS 27 and macOS 27.

Apple primarily made the case for an improved experience with its long-standing Siri assistant, which like most other announcements had a hefty helping of AI.

OS 27’s most powerful on-device AI model will be restricted to some of Apple’s newest products. Here are the details

Apple's most advanced on-device AI model in iOS 27 requires a minimum of 12GB of unified memory, meaning the standard iPhone 17 is excluded. The next generation of Apple Intelligence introduces a new on-device model more powerful than anything Apple has shipped before.

Apple has announced iOS 27 with a redesigned Siri AI, deeper Apple Intelligence integration, and new customization features while extending support to iPhone 11 users.

Apple is improving the iOS interface for iPhone users with iOS 27, which is really injecting Apple Intelligence into every facet of the OS, including Siri.

Apple's recently announced iOS 27 update won't officially ship until the fall, but you can get a taste of the performance improvements and new Siri features the company showed off at WWDC 2026 by downloading a developer beta today.
