Apple Seeds macOS Sequoia 15.4 Release Candidate With Mail Categorization

[MacRumors]

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.

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 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?

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.

It's happened to me, so it's not just MR hype.

But for the vast majority of upgrades I've done, the setting has remained as set.

It's an odd bug and likely will take some time to quash, but it is out there.

Hmmm iPhone says iOS 18.4 Release Candidate

But iPad Pro just says iOS 18.4 thats it no other details..

MacBook Pro shows no update even available :-(

 

[wellander1]

Any rc,s for Mac OS 13.7.5 or 14.7.5?

 

[mcilwraith]

On iOS I turned off mail categories straight away. Terrible feature.

That's 1.8 Mb you're never going to get back.

[ironpony]

Leave my mail alone!

Apple's existing mail categorization hasn't worked in the past - I still get spam in my inbox and real mail in my spam. Now, instead of checking two categories, i will need to do five.

What I would like is a better "auto-file". The existing one learns that you always want emails from Amex to go into "finance-statement" folder; so you click on the folder icon and the learned guess is at the top and the entire folder tree under it. I'd like it to give me three guesses as I sometimes need Amex emails to go into "business-expenses" instead. So, it will learn my 2-3 most common locations and give those as an option.

I don't like Gmail's "everything is an archive, inbox is a tag" type of processing; mostly because i don't use gmail and need separate files for my ISP (like nearly every other ISP). So, I don't want Apple's categories in inboxes because this seems like exactly the same as what Google does - but with only four tags.

 

[SteveLV702]

Nope apple not a release candidate def not ready for release….

Dropbox, TikTok, and dozens of apps still broken as some reason still show iPhone storage as full even though practically empty….

One of the first ones did. Same with iOS.

 

[tahuru]

ILok and NeuralDSP plugins working again. Yeehaw!

 

[star-affinity]

Will the external drive icons I have on the desktop stop moving themselves around in 15.4? 🤔

 

[iPhonNick]

No. On my M1 MacBook Air, it still says it's not available in my country or region. Maybe because I live in the Netherlands.

I'm not even sure it's a bug. If it is, it's one they likely intentionally won't fix. This is just how software is these days. Companies know people are sick of updates and won't turn on new features by themselves.

Might also be an A/B test or something that was left in. Remember this is the company that stealth converted the filesystem on millions of phones and told us about it later.

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?

 

[jz0309]

One of the first ones did. Same with iOS.

There were at least 2 stories about iOS doing that and at least half of the responses were “didn’t happen to me”.
I have been watching the non-beta updates on my Mac and iPad and it did not happen to me.
Don’t know what else to say.

 

[tywebb13]

No. On my M1 MacBook Air, it still says it's not available in my country or region. Maybe because I live in the Netherlands.

if ota not working, there is an ipsw for the rc: https://updates.cdn-apple.com/2025S...EF931A4/UniversalMac_15.4_24E246_Restore.ipsw if you want to use that instead.

they don't usually do full installers for the rc till public release which may or may not have same build
