As Apple prepares to release macOS 15.4, alongside iOS 18.4 and iPadOS 18.4, beta testers are already getting a sneak peek at what’s to come. These updates promise some exciting features that will improve the user experience on your Mac. Let’s take a closer look at four of the standout additions in macOS 15.4 that you can expect soon.
1. Apple Mail Redesign and Enhancements
One of the most notable changes in macOS 15.4 is the complete redesign of Apple Mail. After introducing a refreshed version of the Mail app on iPhone with iOS 18.2, macOS users are finally getting the same treatment. This new design brings a variety of organizational improvements.
Your inbox will now be sorted into categories such as Primary, Transactions, Updates, and Promotions. You can choose to disable these categories or view all emails in the “All Mail” section. Furthermore, emails from the same sender will be grouped together in a new ‘Digest view,’ helping you stay organized. Another noteworthy update is the addition of contact photos for senders in threads, making Mail feel more like the Messages app. This visual overhaul is a great step forward for Apple’s Mail app on the Mac.
2. Verification Code Timer in Apple Passwords
macOS 15.4 brings a small but handy update to the Passwords app, which has already been gaining praise for its functionality. With the new update, Apple adds a verification code expiration timer to help you track when your code will expire. The timer displays as a grey ring that fills up with green as time passes, giving you a visual cue of how much time is left before you need a new code. While it would be even better if the timer appeared directly in the menu bar, it’s a useful feature that enhances the convenience of using the Passwords app.
3. Quick Start for Mac
Apple’s Quick Start feature, which has been available on iPhones and iPads for some time, is now coming to the Mac. This feature simplifies the setup process for new devices by allowing you to scan an animation from your iPhone or iPad to transfer settings like your Apple Account login. In macOS 15.4, you’ll be able to use your Mac as a source device for Quick Start as well, streamlining the setup of new Macs with ease.
4. Expanded Apple Intelligence Languages
macOS 15.4 expands Apple’s AI capabilities by introducing support for more languages. The new update will bring Apple Intelligence to several new languages, including French, German, Italian, Portuguese (Brazil), Spanish, Japanese, Korean, and Simplified Chinese. Additionally, English in India and Singapore will now be supported for the first time. This makes Apple’s AI smarter and more accessible for users around the world.
What Undercode Says: Analyzing macOS 15.4’s New Features
Looking at the new features in macOS 15.4, it’s clear that Apple is focused on enhancing user experience through both design and functionality. The redesigned Apple Mail app is a significant step forward in improving email organization and interface, which users have been asking for. The ability to group emails, sort them into categories, and even view contact photos in threads adds a new level of convenience and personal touch to the email experience. This improvement makes Mail feel far more intuitive and easier to manage than before.
The addition of the verification code timer in Apple Passwords is a small yet valuable upgrade. In today’s digital age, keeping track of time-sensitive verification codes can be tricky. The timer gives users a helpful visual cue, ensuring they don’t miss out on critical logins or security steps. While it could be more integrated into the menu bar for instant visibility, the feature is a useful addition to the Passwords app that enhances security workflows.
Quick Start coming to the Mac is another welcome change. Setting up a new Mac can often feel like a hassle, with users needing to manually input settings. By introducing Quick Start to the Mac, Apple ensures that the transition is faster, more seamless, and less time-consuming for users upgrading or setting up new devices. This added convenience will surely be appreciated by users across the board.
Lastly, expanding the language options for Apple Intelligence is a big move in making Apple’s AI more universally accessible. As Apple continues to grow its global user base, supporting more languages and regions makes sense. The addition of localized English in India and Singapore marks a significant step in making Apple’s AI services more inclusive and functional on a global scale.
macOS 15.4 brings a series of thoughtful improvements that reflect Apple’s commitment to refining its ecosystem. These updates are poised to make the Mac experience more efficient, personal, and accessible, which should resonate well with existing users and potential new customers. And with macOS 16 on the horizon, this update sets a solid foundation for what’s to come.
