WWDC 2026 opened at 10 a.m. PT with Apple revealing the full suite of 27‑series operating systems—iPadOS, macOS, watchOS, tvOS, and visionOS. The company also hinted at new hardware, though insiders say devices are ready to go but will launch only after the refreshed Siri and Apple Intelligence rollouts later this year.

Apple may gate the new Siri features behind a waitlist when iOS 27 launches in September, mirroring the early Apple Intelligence rollout. Internally, the revamped assistant remains a beta, suggesting unfinished polish. The keynote’s software preview should clarify what remains incomplete before public release to developers.

macOS 26 Tahoe will be the last major OS for Intel Macs, a fact revealed last year. Consequently, macOS 27 will support only Apple Silicon, forcing users with legacy chips to stay on older releases. This shift lets Apple focus on silicon‑centric features and streamlines future development.

Tim Cook will deliver his final WWDC keynote, after stepping down as CEO. Software chief Craig Federighi will take center stage, unveiling AI‑centric updates that underpin the new OS releases. Meanwhile, speculative names like macOS Emerald and macOS Big Bear circulate, while the viral Little Finder Guy returns in swag bags.
