The first public betas of iOS 27, iPadOS 27, and macOS 27 Golden Gate are expected this week (the week of July 13, 2026), according to Bloomberg's Mark Gurman . Apple confirmed a July public beta window at WWDC, and developer beta 3 (build 24A5380h) was released on July 6 . Multiple outlets report the public beta will arrive shortly after developer beta 3, placing it in mid-July .
Apple introduced a major Siri overhaul branded Siri AI as part of the next generation of Apple Intelligence . Key features include:
Important regional limitation: Due to the Digital Markets Act (DMA), Apple will not ship Siri AI in the European Union with the initial release of iOS 27 and iPadOS 27 .
Access to the new Siri AI is not immediate for beta testers. After updating to iOS 27, users must:
This is similar to the waitlist system Apple used for Apple Intelligence during the iOS 18.1 beta cycle . The rollout is phased, starting with developer beta users, and early reports suggest the wait can range from 4 to 48 hours . Apple is still internally labeling the revamped Siri as a "beta" and "preview," suggesting it won't be marketed as finished software when it arrives .
iOS 27 — Supported iPhones
Apple confirmed that every iPhone currently running iOS 26 is eligible for iOS 27, going back to the iPhone 11 series (2019) . The full list, according to Apple's official compatibility page, includes: iPhone 17 series, iPhone Air, iPhone 17e, iPhone 16 series, iPhone 16e, iPhone 15 series, iPhone 15 Pro, iPhone 14 series, iPhone 13 series, iPhone 12 series, iPhone 11 series, and iPhone SE (2nd generation and later) .
Siri AI / Apple Intelligence — Hardware Requirement
Running iOS 27 and running full Siri AI are not the same. The advanced Apple Intelligence features with on-device semantic processing require iPhone 15 Pro or newer (or an M-series iPad/Mac) due to intense local compute demands . Older iPhones (e.g., iPhone 11 through iPhone 15/15 Plus) will get iOS 27 but will not have access to the full Siri AI experience .
Furthermore, the most powerful on-device AI features — including expressive Siri voices and advanced dictation — require devices with at least 12 GB of unified memory. This currently means the iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air (plus newer iPads and Macs with sufficient RAM) .
macOS 27 Golden Gate is the first version of macOS to run exclusively on Apple silicon Macs — it drops support for Intel Macs entirely . Any Mac with an M-series chip (M1 and later) is supported, including: MacBook Air (M1 and later, 2020+), MacBook Pro (M1 and later, 2020+), iMac (M1 and later, 2021+), Mac mini (M1 and later, 2020+), Mac Studio (2022+), Mac Pro (Apple silicon, 2023+), and the MacBook Neo (2026) .
Note: The developer beta requires a $99/year Apple Developer account; the public beta is free .
