Apple Seeds Fourth Beta of macOS Sequoia 15.4 With Mail Categorization

Apple today provided developers with the fourth beta of an upcoming macOS Sequoia 15.4 update for testing purposes. The new beta is available a week after Apple released the third beta.

macOS Sequoia Feature
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.

Mail categorisation yet another reason on the list of why I'm sticking to Sonoma.
Because clicking the "Disable" button the first time you open Mail is too hard?

Maybe I'm the minority, but after a bit of training, I've found the new iOS Mail categorization has helped me quite a bit. Out of the box it was a bit off base, but as I've taken time to manually categorize incoming mail, it's started to do a lot better.

Mail categorization has been an epic fail thus far. Hopefully they managed to get a feature Gmail has had for a decade working better this time around.

Does it has Siri improvements?
Yep, it says “sorry I didn’t get that” without any lag

I will bet $5,000 dollars that the OS will still be too stupid to remember where I place my Stickies and Finder windows.

So many dumb and useless "enhancements" but they can't even figure out how to store and recall window positions and sizes. It's 2025, Apple. 2025.
