Apple has recently rolled out a series of comprehensive updates across its platforms, addressing both security concerns and introducing new features. Notably, the company has released security patches for older iOS and iPadOS devices dating back to 2014, including iPhone 8, iPhone X, and older iPads, to fix critical vulnerabilities such as the Coruna exploit, which could allow malware installation via malicious web content. Users running iOS 13 or 14 are urged to upgrade to iOS 15, while those on iOS 15 and 16 should install the latest patches. Apple also recommends enabling Lockdown Mode for added protection.
Alongside these security measures, Apple has introduced a new architecture called 'Background Security Improvements', which delivers smaller security updates between full operating system releases. This system uses cryptographically sealed disk images that can be updated via binary patches, enabling faster and more energy-efficient security fixes. This approach enhances Apple’s ability to respond quickly to emerging cyber threats and reflects the company’s ongoing commitment to strengthening device security.
The upcoming iOS 26.4 update, expected to be released next week, includes a range of new features in addition to security fixes. These include eight new emojis, a redesigned Apple Music interface with AI-powered features, and improvements to the keyboard that resolve an issue where keys were recognized during fast typing but no characters were entered. The update also enhances Liquid Glass and is already available to beta testers. The update package extends to iPadOS 26.4, macOS 26.4, watchOS, tvOS, visionOS, and HomePod.
macOS 26.4 introduces specific improvements for MacBooks, including a new feature that limits battery charging to 80–95% to extend battery lifespan. It also includes a warning for non-ARM-optimized applications, as Rosetta 2 will be discontinued with macOS 28. The compact tab layout in Safari has been restored, among other enhancements. These updates serve as a prelude to WWDC 2026, where iOS 27 and macOS 27 are expected to be unveiled.
In the EU, Apple has allowed sideloading of apps from alternative app stores since 2024, enabling access to modified applications without jailbreaking. These apps are signed using developer certificates and can be automatically updated, although the process remains more technically demanding than on Android. At the same time, trialogue negotiations on chat surveillance in the EU have failed, potentially ending mandatory monitoring of private communications. Researchers have criticized the algorithm used, which is easily bypassed and prone to false reports.
The broad range of updates demonstrates Apple’s efforts to continuously improve both security and user experience. The introduction of 'Background Security Improvements' and regular, comprehensive patches underscore a strategic focus on rapid response to cyber threats. Meanwhile, new features in iOS 26.4 and macOS 26.4 highlight platform evolution, while EU developments offer users new freedoms—while also highlighting the importance of privacy and secure technology.
