Apple Releases iOS 26.4 with 70+ Security Fixes
Apple has released version 26.4 for its operating systems, including iOS, iPadOS, macOS, watchOS, tvOS, visionOS and HomePod software. The update patches a large number of security vulnerabilities (Apple lists over 70 fixes for macOS 26.4), improves system behaviour (keyboard responsiveness, Liquid‑Glass UI controls), and adds user features such as eight new Unicode 17 emojis, an Apple Music ambient/concert widget, and optional compact Safari tab/address layout on iPad and Mac. Apple integrated the Freeform whiteboard app into the paid Creator Studio and changed Family Sharing so adult members can add their own payment methods. Some features tested in betas — notably end‑to‑end encryption for RCS and other items — will arrive later. The release also includes EU‑specific interoperability changes allowing certain third‑party watches and headphones to receive/handle iOS notifications and device switching within EU member states.

Apple releases iOS 26.4 with security and family features
Apple released version 26.4 of its operating systems, rolling out updates for iOS, iPadOS, macOS, watchOS, tvOS, visionOS and HomePods. The update adds eight Unicode 17.0 emojis (including Bigfoot), an Apple Music widget for ambient music and concert info, keyboard precision improvements, and accessibility controls to disable bright 'Liquid‑Glass' blinking. Apple integrated the Freeform whiteboard into its paid Creator Studio, restored a compact Safari tab/address layout option on iPad and Mac, and for the first time lets adult family‑sharing members add their own payment methods. Several tested features will arrive later (notably end‑to‑end encryption for RCS messaging). The release includes numerous security patches — Apple cites over 70 fixes for macOS 26.4 and addresses a telephony‑framework kernel vulnerability — and Apple also provided legacy security updates for older device models.
Apple releases iOS 26.6 and broad security updates
Apple issued incremental updates in late July 2026 (published July 30, 2026) for iOS 26.6, macOS 26.6 (Tahoe), iPadOS 26.6, watchOS 26.6, visionOS 26.6, tvOS 26.6 and HomePod software. The releases deliver general bug fixes and extensive security patches — roughly 160 fixes for Mac and about 90 for iPhone/iPad — plus security updates for older macOS releases (Sonoma and Sequoia) and Safari. They include a Spotlight search index update intended to prepare devices for iOS 27 and to accelerate the forthcoming Siri AI, which Apple plans to ship in the autumn with limited initial availability in the EU. Apple characterized the rollouts as incremental, focused on security and stability, and said none of the patched vulnerabilities were known to have been exploited in the wild at the time of release.
Apple releases iOS 26.6.1 security patch
Apple released iOS and iPadOS 26.6.1 and macOS Tahoe 26.6.2 to address more than 20 security vulnerabilities across iPhone, iPad and Mac devices. Many fixes target the WebKit browser engine used by Safari — including crashes and a history-related flaw that could expose sensitive data — and Apple also patched issues that could enable data exfiltration via an audio app, cause system crashes, or permit denial-of-service. Apple published a support document summarizing the addressed issues while withholding full technical details until users install updates. Industry reporting suggests these may be the final patches before iOS 27, expected in September 2026, and that Apple plans to issue more security-focused updates as AI-driven vulnerability discovery and exploitation accelerates. Users are advised to install the updates promptly.
