Apple Seeds macOS Sequoia 15.4 Release Candidate With Mail Categorization

Apple today provided developers with the release candidate version of an upcoming macOS Sequoia 15.4 update for testing purposes. The new beta is available a week after Apple released the fourth 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, and the RC represents the finalized version of the software that will be launched to the public as long as no issues are found.

So, the update will turn on Apple AI again, I suppose? I wish Apple would stop doing this, do they think we will get fed up turning it off and start using it?
I don't want AI on my computer, simple as that and looking at the muck ups that these AI things are making, they seem to be about as useful as a bucket with a hole in.

I've said it before, but removing most first party apps from the OS in favor of independent updates would be a welcome change for me. Something as simple as mail categories could be added much quicker in a standalone mail pipeline. Let alone the ability for me to uninstall Mail.app if it weren't tied to OS, as I don't use it. Or the multitude of bloat apps, like Stickies from Tiger, effectively replaced over a decade ago with Notes in Mountain Lion.

On iOS I turned off mail categories straight away. Terrible feature.
It was about 80% wrong for me over a period of a week. I turned it off as well.

What is the point of categorizing mail if I to check every category every time I open the mail app it to make sure I didn't miss anything?

I'm glad I'm not the only one who views it this way. I strongly dislike the email categories in Google's Gmail and pretty much everywhere else I find them.

My feeling is, categories just cause me to miss email I need to see, AND it encourages hanging onto a lot of useless junk mail because it gets "tucked away" under various category tabs where you forget about it.

What I think mail clients *really* need are more tools to allow selectively deleting groups of mail based on criteria you specify. I'd love it if, for example, I open a piece of mail from Walgreens and could just right-click on it to get a menu with a "Remove all mail from this sender received before" and get prompted for a date.

Sometimes, I don't mind getting "junk mail" from restaurants or stores I frequent, but I definitely don't need their older mail with expired offers or sales hanging around.

I still find that feature very creepy, even if it is done locally. Does it also read all the dirty messages you exchange with your friend with benefits?
