Apple Unveils Third Public Beta of macOS Tahoe 26.4 with Exciting New Features
On March 4, 2026, Apple released the third public beta of the upcoming macOS Tahoe 26.4, inviting users to explore and test the latest enhancements before the official release. This update introduces several notable features aimed at improving user experience and system performance.
Reintroduction of Safari’s Compact Tab Layout
Responding to user feedback, Apple has reinstated the Compact tab layout in Safari. This design condenses the tab bar, allowing for more efficient use of screen space and a streamlined browsing experience. Users who preferred this layout in earlier versions of macOS Tahoe can now enjoy its return.
Introduction of the Charge Limit Feature
A significant addition in macOS Tahoe 26.4 is the Charge Limit feature. This functionality enables Mac users to set a maximum charge level for their devices, adjustable between 80% and 100%. By capping the charge, users can potentially extend the lifespan of their Mac’s battery, as maintaining a full charge for prolonged periods can contribute to battery degradation over time.
Rosetta 2 Deprecation Warnings for Apple Silicon Macs
Apple continues its transition away from Intel-based architecture. In this beta, Apple Silicon Mac users will receive warnings when running applications that rely on Rosetta 2, the translation layer that allows Intel-based apps to run on Apple Silicon. This serves as a reminder that support for Rosetta 2 will be phased out after macOS 27, urging developers and users to update their applications accordingly.
Final macOS Version for Intel-Based Macs
macOS Tahoe 26.4 marks the final version of macOS that will support Intel-based Macs. Apple is actively working to remove lingering Intel-specific features, signaling a complete shift towards Apple Silicon. Users with Intel-based Macs should be aware that future macOS updates will not be compatible with their hardware.
Anticipated Additional Features
While the current beta introduces significant updates, Apple is expected to add more features in subsequent versions of macOS Tahoe 26.4. Potential additions include new emoji characters and other enhancements aimed at enriching user interaction and system functionality.
Participation in the Public Beta Program
Users interested in testing the new features can enroll in Apple’s public beta program. After signing up on Apple’s beta site, participants can download the update via the Software Update section in the System Settings app. It’s important to note that beta software may contain bugs or issues, so it’s advisable to install it on a secondary device or ensure that important data is backed up.
Looking Ahead
Apple plans to continue testing macOS Tahoe 26.4 over the coming weeks, with an official release anticipated in the spring. This period allows for the identification and resolution of any issues, ensuring a stable and polished final version for all users.
