Apple has released the second beta of macOS Sequoia 15.4 for developers, arriving two weeks after the first beta. This update introduces several new features and advancements, bringing a more refined experience to Mac users.
Developers can install the beta by opting in through the Software Update section in System Settings, provided they have an Apple ID linked to an Apple Developer account.
One of the most significant updates in macOS Sequoia 15.4 is the introduction of Mail categorization. Similar to its implementation in iOS 18.2, this feature organizes the inbox into four distinct categories: Primary for essential and time-sensitive messages, Transactions for receipts and confirmations, Updates for news and social notifications, and Promotions for marketing emails and coupons. Additionally, the Mail app now includes a digest view that groups emails from the same sender, making it easier to scan for important messages at a glance.
Apple Intelligence is also seeing notable improvements in this update. Image Playground has gained a new Sketch style, enabling users to create artistic images more easily. Furthermore, Apple Intelligence now supports additional languages, including Chinese, French, German, Italian, Brazilian Portuguese, Spanish, Japanese, Korean, and localized English for Singapore and India.
Another highlight of macOS Sequoia 15.4 is a proximity pairing feature, streamlining the setup process for new Macs. By bringing an iPhone close to the Mac, users can automatically transfer settings and preferences, making the onboarding process faster and more convenient.
For Apple News+ subscribers, a dedicated News+ Food section is now available, offering curated content such as recipes, restaurant reviews, and articles related to food culture. Additionally, the Photos app now allows users to create Memory Movies, bringing a more personalized touch to their photo collections.
Emojis are also getting an update in macOS Sequoia 15.4. Apple is expected to introduce seven new emojis based on the Unicode 16 standard, including a face with bags under the eyes, a fingerprint, a leafless tree, a root vegetable, a harp, a shovel, and a splatter. Meanwhile, the Genmoji feature has been refined, with Apple tweaking the Genmoji button on the keyboard to make it more discoverable.
Despite these updates, one anticipated feature missing from macOS Sequoia 15.4 is a major Siri upgrade. Reports suggest that Apple has pushed these improvements to macOS Sequoia 15.5 and iOS 18.5, which are expected to be released in May.
Alongside this release, Apple has also rolled out the second beta versions of iOS 18.4, iPadOS 18.4, tvOS 18.4, visionOS 2.4, and watchOS 11.4.
