The first public betas of Apple's next-generation operating systems — iOS 27 and macOS 27 Golden Gate — are arriving this week. Based on confirmed developer beta releases and reporting from Bloomberg, here's the complete timeline, the full list of covered devices, the major child safety overhaul, and what the new Siri AI architecture means for users and developers.
Public Beta Release Timeline
According to Bloomberg's Mark Gurman, the first public betas of iOS 27, macOS Golden Gate, and other major OS updates will be released the week of July 13, 2026
. This aligns with Apple's previously stated July timeframe
and matches the historical pattern of public betas arriving 4–6 weeks after the WWDC keynote [7, 14].
The developer beta progression that led to this point:
| Milestone | Date |
|---|
| WWDC 2026 keynote & dev beta 1 | June 8, 2026 [1, 2] |
| Developer beta 2 | June 22, 2026 [7, 12] |
| Developer beta 3 | July 6, 2026 [4, 11] |
| Public beta 1 | Week of July 13, 2026 (expected) ![]() |
| Final public release | September 2026 [3, 5] |
Apple released developer betas on a roughly biweekly cadence (beta 2 on June 22, beta 3 on July 6), so by July 13 the third developer build is mature enough for a wider public beta [11, 14].
Operating Systems Covered
The public beta wave covers six OS families: iOS 27, iPadOS 27, macOS 27 (Golden Gate), watchOS 27, tvOS 27, and visionOS 27 — all announced at WWDC 2026 as "coming this fall" [3, 8]. The child safety and Siri AI features primarily span iOS 27, iPadOS 27, and macOS 27 [10, 13].
