What Is New in macOS Sequoia (2024 Mac Update)

macOS Sequoia is Apple's major Mac software update released in September 2024. If your Mac is reasonably current, you may have already installed it — or been asked to. This guide explains what is actually new, why it matters, and how to start using the best new features.

macOS Sequoia works on Macs from 2019 and later (for most models). To check which macOS version you have, click the Apple menu in the top-left corner and choose "About This Mac." If it says "macOS Sequoia," you are on the latest major version. You can check for smaller updates under System Settings > General > Software Update.

The biggest new feature is iPhone Mirroring — the ability to see and control your iPhone screen directly on your Mac. This is covered in its own guide, but briefly: as long as your iPhone is nearby and running iOS 18, you can open the iPhone Mirroring app on your Mac and use your iPhone entirely from your computer.

The second major addition is a dedicated Passwords app. Before Sequoia, your saved passwords were buried inside System Settings. Now there is a standalone app called Passwords where you can view, search, and manage all your saved usernames, passwords, and passkeys in one clean interface.

Window tiling is another practical addition — your Mac can now automatically snap windows into neat arrangements on your screen, similar to a feature Windows has had for years. And Apple Intelligence — Apple's new set of AI features — debuts in Sequoia for Macs with Apple Silicon chips (M1, M2, M3, and later).
