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.

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.

Apple today provided public beta testers with the third release of an upcoming macOS Tahoe 26.4 update for testing purposes. The public beta comes a week after Apple seeded the second beta.


After signing up for beta testing on Apple's beta site, public beta testers can download the updates using the Software Update section in the settings app for each update.

‌macOS Tahoe‌ 26.4 includes several new features. The Compact tab layout has been reimplemented in Safari for those who missed having the option in earlier versions of ‌macOS Tahoe‌, and there is a new Charge Limit feature that lets Mac users select a maximum charge level that ranges from 80 percent to 100 percent.

Apple silicon Mac users will see now see warnings about apps that are still using Rosetta 2, because Apple is phasing out Rosetta after macOS 27. ‌macOS Tahoe‌ is also the final version of macOS that will run on Intel-based Macs, and Apple is working to remove all lingering Intel features.

We could see additional features in upcoming versions of ‌macOS Tahoe‌ 26.4, such as new emoji characters. Apple is expected to test the update for the next several weeks, with a launch planned for the spring.

macOS 26.3 hints at Apple's rumored lower-cost MacBook, and two new Studio Display models, according to Macworld's Filipe Espósito.


Espósito found the following codenames within macOS 26.3's source code, and he revealed the upcoming products that they likely correspond with, based on previous reporting from Bloomberg's Mark Gurman and others.

The codenames:

• J700: Lower-cost MacBook


• J427: A new Studio Display


• J527: A new, higher-end Studio Display

This is far from the first time that these codenames have been spotted in Apple's software updates. According to MacRumors contributor Aaron Perris, the codenames were also present in updates such as macOS 26.2 and iOS 18.5 last year.

As more and more hints stack up, it is clear that all three products are inching closer to release.

The prevailing assumption is that Apple will unveil the lower-cost MacBook as part of three days of new product announcements in the first week of March. The media would then receive hands-on time with the laptop during the "Apple Experience" in New York, London, and Shanghai on Wednesday, March 4 at 9 a.m. Eastern Time.

The new Studio Displays are expected to be released in the first half of 2026, but it is unclear if they will be part of the announcements in the first week of March.


The lower-cost MacBook is rumored to be powered by a version of the iPhone 16 Pro's A18 Pro chip, rather than an M-series chip. The laptop will apparently be available in a variety of bright colors, such as yellow, green, blue, and/or pink. Other rumored specs include a 12.9-inch display and 8GB of RAM. The starting price remains to be seen, with estimates ranging from $599 to $799 in the United States.

The lower-cost MacBook would be an all-new model positioned below the MacBook Air, and it would mark a revival of the "MacBook" brand (with no "Air" or "Pro" designation). Apple sold an Intel-based 12-inch "MacBook" from 2015 to 2019.

At least one of the new Studio Display models is rumored to feature a 27-inch screen with mini-LED backlighting, up to a 90Hz or 120Hz refresh rate, HDR support, and an A19 chip or A19 Pro chip. No major design changes are expected.

If the next Studio Display receives mini-LED backlighting and HDR support, its maximum brightness and contrast ratio would be higher than the current model. And a newer A19 or A19 Pro chip — up from the A13 Bionic currently — should contribute to performance improvements, camera-related enhancements, and more.

There are no details about the second Studio Display. Presumably, it would be a higher-end model, and we can only dream of a larger 32-inch screen size.

The current Studio Display launched in March 2022, alongside the first Mac Studio. It has a 27-inch screen without mini-LED backlighting, a 5K resolution, a 60Hz refresh rate, up to 600 nits brightness, a built-in camera and speakers, one Thunderbolt 3 port, and three USB-C ports. In the U.S., pricing starts at $1,599.
