With the RC, Apple provided the release notes for macOS Sequoia 15.3, so if you want to know exactly what's coming, here are the details.

This update introduces Genmoji, powered by Apple Intelligence, and also includes other enhancements, bug fixes, and security updates for your Mac.
- Genmoji creation in Messages and other apps
- Calculator repeats the last mathematical operation when you click the equals sign again
- Easily manage settings for notification summaries from the Lock Screen (Mac with Apple silicon)
- Updated style for summarized notifications better distinguishes them from other notifications by using italicized text as well as the glyph (Mac with Apple silicon)
- Notification summaries for News & Entertainment apps are temporarily unavailable, and users who opt-in will see them again when the feature becomes available (Mac with Apple silicon)
Some features may not be available for all regions, or on all Apple devices.

With the exception of Genmoji, a feature that was already available in iOS and iPadOS, these release notes also pertain to iOS 18.3 and iPadOS 18.3.

I will literally pay 499/year, maybe even more, for a "macOS Pro" that removes all the shareholder-pushed consumer BS (No AI, no genmoji, garageband, bloatware Tips, News, and TV apps etc.) and is just rock solid snow leopard 10.6.8 syle constant performance, compatibility, stability updates and nothing else. like basically windows 10 LTSC

Part of the allure of macOS is that it was built as a UNIX-compliant operating system, which keeps it broadly compatible with a wealth of third-party software.

I fear that Apple has lost sight of that, and is making macOS more proprietary by the year, to a point where it may no longer be UNIX-compliant.

Lets hope that never happens.

What I'd really like is support for RAW files with Canon's R5 Mark II camera. I would hate to have to wait until macOS 16 for that.
Nah, instead you're gonna get more AI generated emojis and RAM hogging widgets for shopping apps and you'll like it.

Why is Apple so obsessed with emojis and gemojis, it’s just stupid, immature. Fix the bugs.
