Mac owners can download the software by opening the System Settings app and then navigating to the Software Updates section.

According to Apple's release notes for the update, ‌macOS Tahoe‌ 26.5.1 addresses an unexpected shutdown issue affecting certain enterprise users on M5 Macs.

This update addresses an issue for enterprise users where Macs with an M5 chip could expectedly shut down when using certain content filtering network extensions.

Apple today provided public beta testers with the first betas of iOS 26.6, iPadOS 26.6, macOS Tahoe 26.6, watchOS 26.6, and tvOS 26.6, with the software coming two days after Apple seeded the betas to developers.


After signing up to beta test the software updates on Apple's beta site, public beta testers can download the new software using the Software Update section in the Settings app on each device.

iOS 26.6 has a feature that will let you know when you have blocked too many contacts, but the limit is in the thousands so most users may not ever see the messaging.

No other major new features have been found in any of the software updates, with Apple likely focusing on bug fixes and security improvements. We're nearing the end of the "26" software cycle, with Apple planning to unveil iOS 27, iPadOS 27, macOS 27, and more in 11 days.

Anthropic recently announced Project Glasswing, an initiative that enables tech companies like Apple to use its new frontier AI model Claude Mythos Preview to find security vulnerabilities across operating systems and web browsers.


The Wall Street Journal today reported that researchers at cybersecurity firm Calif used Claude Mythos Preview to uncover a new macOS security vulnerability last month. Specifically, they used the model to write code that links together two macOS bugs in a way that resulted in what is known as a privilege escalation exploit.

The security researchers said the exploit would not have been possible with Mythos alone, as it still required their human expertise on top, but it nevertheless proves that AI can assist with discovering software vulnerabilities.

Apple said it was reviewing Calif's report to validate the findings.

"Security is our top priority, and we take reports of potential vulnerabilities very seriously," an Apple spokesperson told The Wall Street Journal.

It is unclear if Apple has already patched the exploit. Apple's security notes for the macOS 26.5 update released this week mention a fix for a kernel-level vulnerability, and it credits Calif and Anthropic for discovering it. Yet, the report said that Calif only met with Apple this week and suggested that a fix was still coming.

We have reached out to Apple for comment.

Apple is continuing to highlight the Liquid Glass aesthetic that it introduced in iOS 26, iPadOS 26, and macOS 26. The company has shared an updated Liquid Glass Design Gallery that shows off Liquid Glass in third-party apps.


The visual gallery features several iPhone and iPad apps, with screenshots that show the difference between app design in iOS 18 and ‌iOS 26‌.

In the latest edition of our new design gallery, find out how teams of all sizes are taking advantage of the new design and Liquid Glass to create natural, responsive experiences across Apple platforms.

Apps included in the gallery have adopted Liquid Glass for elements like tab bars, navigation buttons, bottom toolbars, and more. Apple also highlights pop-out menu interfaces and the separate search buttons that some apps have implemented, both of which are Liquid Glass design elements that Apple has added to its own apps.

AllTrails, Carrot Weather, Fantastical, Kroger, SketchPro, Trello, and Le Monde are among the apps featured.

Apple previously shared a Liquid Glass gallery after the ‌iOS 26‌ launch, and that gallery provides more Liquid Glass design examples.

Since debuting Liquid Glass, Apple has made small changes like adding a slider bar to the Lock Screen clock for adjusting the Liquid Glass level, but no major updates have been introduced. Rumors suggest that iOS 27, iPadOS 27, and macOS 27 will continue to feature the Liquid Glass aesthetic with little change, but Apple could also add a system-wide slider bar for Liquid Glass opacity adjustments.

Apple today released the first Background Security Improvement (BSI) update, replacing the rapid security updates that it used to seed out a few years ago. The first BSI updates address a WebKit vulnerability that could allow maliciously crafted web content to bypass Same Origin Policy. There's a macOS Tahoe 26.3.1, iOS 26.3.1, and iPadOS 26.3.1 BSI update, as well as a ‌macOS Tahoe‌ 26.3.2 BSI update exclusive to the MacBook Neo.


Apple says that the vulnerability was addressed with improved input validation.

Background Security Improvements were added with iOS 26, iPadOS 26, and ‌macOS Tahoe‌, and Apple tested them in iOS 26.3, iPadOS 26.3, and ‌macOS Tahoe‌ 26.3 before today's official release.

The updates are meant to provide additional security protections between software updates for Safari, WebKit, and other system libraries. Background Security Improvements can be installed in the Privacy and Security section of the Settings app. Scroll down, and then select the Install option to install the update. If Automatically Install is toggled on, BSIs will be automatically installed when they come out.

Users who opt not to install Background Security Improvements will receive the fixes in a subsequent standard software update.

Apple warns that Background Security Updates can result in "rare instances of compatibility issues." Should that occur, the updates may be temporarily removed and enhanced in another software update.
