macOS Sequoia 154 Beta 4: What's New and What's Next?

Apple’s latest macOS Sequoia 15.4 beta 4 update has just arrived for developers, marking the next step toward the anticipated public launch. Following a quick turnaround from the previous beta release, here’s a closer look at what this update brings and what to expect before the final version rolls out in just a few weeks.

What’s New in macOS Sequoia 15.4 Beta 4?

After the relatively minor changes in macOS 15.4 beta 3, the new beta 4 continues the trend, focusing primarily on bug fixes and performance enhancements. While no groundbreaking features are expected this time, the window for significant updates before the public release is quickly closing. With iOS 18.4 slated for an early April release, macOS 15.4 will likely follow suit, meaning the official version could be just weeks away.

Key Features in macOS 15.4:

Apple Mail Redesign: A major overhaul of the Mail app, now featuring improved inbox categorization and enhanced functionality.
New Emojis: The system keyboard now includes seven fresh emojis for users to enjoy.
Proximity Pairing: This new feature makes setting up devices more seamless by using proximity to pair devices automatically.
Verification Code Timer: In the Passwords’ Menu Bar app, users will now see a timer for verification codes, making it easier to track expiration times.
Sketch Style in Image Playground: A new sketch-like style for better creative options in the Image Playground app.
Other Minor Tweaks: Expect some additional subtle improvements aimed at refining the overall user experience.

How to Install macOS 15.4 Beta 4

To update to macOS 15.4 beta 4, navigate to System Settings > General > Software Update on your Mac. If the update doesn’t appear, click the ‘i’ button and make sure Beta Updates are enabled in your settings.

What Undercode Says: Analyzing the macOS 15.4 Beta 4 Update

As we get closer to the public release of macOS 15.4, Apple is likely focusing its efforts on squashing bugs and fine-tuning performance. While this update might not introduce revolutionary new features, it’s clear that Apple is setting the stage for a more polished final version.

In terms of changes, macOS 15.4 beta 4 represents more of the same — bug fixes and minor refinements. This is typical in the final stages of a beta cycle, where developers ensure that any kinks in performance or compatibility are addressed before the broad release. Although Apple has already rolled out several exciting features like the revamped Apple Mail and the much-anticipated proximity pairing, beta 4 seems like a subtle refinement to ensure stability.

The upcoming public release is expected to coincide with the launch of iOS 18.4, and macOS 15.4 will likely follow in tandem. This suggests that Apple is working hard behind the scenes to ensure everything is in place for a smooth rollout. Given the anticipated proximity of the release, it’s safe to say that major new features will probably be limited to the changes already previewed, like the new emojis and the improved Mail app.

That being said, Apple could still surprise us with a last-minute change in beta 4, though it seems unlikely given the timing of the update cycle. Now that we’re so close to the public launch, it’s all about fixing bugs and ensuring stability, particularly for users relying on this software for their day-to-day tasks.

Fact Checker Results:

Update Frequency: The quick succession of macOS betas suggests Apple is focused on bug fixing in the final stretch before release.
Feature Refinement: Beta 4 doesn’t introduce new features, staying consistent with earlier releases.
Expected Launch Timeline: The upcoming public launch of macOS 15.4 aligns closely with the iOS 18.4 release in early April, indicating a smooth, synchronized rollout.
