Apple Seeds Second macOS Sequoia 15.4 Release Candidate With Mail Categorization

Apple today provided developers with a second release candidate version of an upcoming macOS Sequoia 15.4 update for testing purposes. The new RC is available a few days after Apple released the initial RC earlier this week.

Registered developers can opt-in to the macOS Sequoia beta through the Software Update section of the System Settings app. An Apple ID associated with an Apple Developer account is required to get the beta.

macOS Sequoia 15.4 brings Mail Categorization to the Mac for the first time, reorganizing the Mail app into dedicated categories like transactions, updates, promotions, and primary, a category that surfaces the most important emails first. The update brings a range of new emoji characters to the Mac.

For Apple News+ subscribers, there is a dedicated News+ Food section with recipes, articles about restaurants, and other related content. There's a new Sketch style in Image Playground, the option to create Memory Movies in the Photos app, and Apple Intelligence is expanding to new languages.

Apple plans to release macOS Sequoia 15.4 in early April, and the RC represents the finalized version of the software that will be launched to the public as long as no issues are found.
