macOS Sequoia: The 5 Best New Features for Productivity

macOS Sequoia is macOS 15. Five of its additions genuinely changed daily work: built-in window tiling, iPhone Mirroring, Safari Distraction Control, the standalone Passwords app, and Math Notes. Here is what each one actually does, what it requires, and where it still falls short of the third-party tool it replaced.

Is macOS Sequoia still the release to be on?

Not any more. Sequoia has since been followed by newer versions of macOS, so if your Mac supports a later release, that is the one to install. Everything described below carried forward into those releases, which is why the features are still worth knowing.

One thing did not carry forward. Launchpad, the full-screen app grid that had been part of macOS since Lion, was removed in macOS 26 Tahoe and replaced by the Applications view inside Spotlight. If you upgrade past Sequoia and go looking for it, our guide to what to use instead of Launchpad on macOS Tahoe covers the options.

1. Native window tiling

After years of people installing Rectangle or Magnet on a fresh Mac before anything else, macOS gained built-in window snapping. Drag a window to a screen edge and it fills that half. Drag it into a corner and it takes that quarter. A translucent preview shows where it will land before you let go.

The part worth knowing about is the menu. Open the Window menu in any app and look at Move and Resize: every arrangement is listed there with its keyboard shortcut printed beside it, which saves guessing. Two related switches live in System Settings, then Desktop and Dock: one controls whether dragging to an edge tiles at all, and one controls whether tiled windows keep a small margin between them or sit flush.

Where it still falls short. The built-in feature covers halves, quarters and fill. It does not do thirds or sixths, it does not remember a layout per app or per display arrangement, and you cannot assign your own shortcuts to arrangements it does not offer. If you work in three columns on an ultrawide display, a dedicated window manager is still the better tool. For everyone else, the built-in version is enough and it is free.

2. iPhone Mirroring

Your iPhone screen appears in a window on your Mac, and you drive it with the Mac's keyboard, trackpad and mouse. You can answer messages, use an iPhone-only app, and work through notifications without picking the phone up. The phone stays locked while you do it and displays a notice that it is in use, so nobody standing next to it can read along.

What it requires, because this is where most failures come from:

• An iPhone running iOS 18 or later, and a Mac running Sequoia or later.
• The same Apple Account signed in on both devices, with two-factor authentication on.
• Bluetooth and Wi-Fi turned on for both.
• The iPhone nearby, locked, and not being used by someone else.

Availability also varied by region when the feature first shipped, so if the app refuses to start and everything above checks out, that is worth ruling out before you spend an evening on it. Drag and drop between the mirrored phone and the Mac was not there on day one either; it arrived in a later update to Sequoia.

3. Safari Distraction Control

Open the page menu in Safari's address field and choose Hide Distracting Items. You then click the things on the page you never want to see again on that site: the newsletter overlay, the sticky video player, the cookie strip that survived your last refusal. They disappear, and they stay gone on later visits.

Apple is careful about what this is, and so should anyone recommending it be. It is not an ad blocker. It hides specific items you pointed at, and hidden items can reappear if the page content underneath them changes. On a site you read daily it is excellent. As a general defence against advertising it is not the right tool.

Safari also gained Highlights, which surfaces details like directions or contact information from a page, and a cleaner Reader. Highlights is pleasant and occasionally useful, and not something you will notice missing.

4. The Passwords app

iCloud Keychain finally got a proper app instead of a panel buried in System Settings. Passwords handles passwords, passkeys, verification codes, Wi-Fi credentials and shared groups, syncs across Mac, iPhone and iPad, and reaches Windows through iCloud for Windows. It autofills in Safari, and in other browsers through an extension.

For personal use inside the Apple ecosystem, it is a fair replacement for a paid password manager, and the shared groups feature covers most of what families were paying for. The honest limits: it is tied to your Apple Account, so it is a poor fit if you want your credentials portable to a non-Apple future, and it is not a general secure store for documents and scanned records the way some paid managers are.

5. Math Notes and the new Calculator

The one that quietly changed how a lot of people do rough calculations. Type an expression into Notes, follow it with an equals sign, and the answer appears. Assign values to names and reuse them, and the results update as you change the inputs. Calculator picked up the same capability, along with unit conversion and a visible history of what you have typed.

It is not a spreadsheet and it does not want to be. What it replaces is the habit of opening a spreadsheet to work out three numbers, which is a worse tool for that job than a line of text.

Which Sequoia features can you safely ignore?

Not everything in the release earns your attention. The video conferencing background replacement is fine and you will configure it once. Apple Intelligence arrived after the initial release, runs only on Apple Silicon Macs, and was gated by language and region at first, so whether it is even available to you depends on your hardware and where you are. Judge it on what it does on your machine rather than on the announcement.

Pairing this with a faster way to open apps

Tiling solves arranging windows. It does not solve getting the right four apps open in the first place, which is still the part that costs the most time at the start of a task.

That is the gap a launcher fills. ShortcutDock puts a grid of your apps behind the menu bar icon or a global hotkey you choose, and its Groups let you open a whole set at once: launch the group, then tile the windows with Sequoia's own shortcuts. It runs on macOS 13 Ventura and later, so Sequoia is comfortably covered, and it is built natively for Apple Silicon and Intel rather than wrapped in a web runtime.

If you want the keyboard half of this, our list of essential Mac shortcuts covers the built-in ones worth committing to memory, and organising Mac apps with groups covers the launching half. The whole arrangement is written up in our Mac productivity setup for 2026, and you can download ShortcutDock to try the launcher part of it for nothing.
