macOS Sequoia landed with a lot of fanfare around Apple Intelligence, but buried beneath the AI headlines are some genuinely excellent quality-of-life features that most users haven't discovered yet. After spending months with Sequoia, I've rounded up the 12 best hidden features that deserve a lot more attention — from a completely redesigned window manager to a built-in password manager that might finally replace your third-party app.
Whether you're on an M-series MacBook or an older Intel Mac, many of these features are available to you right now. Let's dig in.
1. Window Tiling Is Finally Built In
For years, Mac users who wanted proper window snapping had to rely on apps like Magnet, BetterSnapTool, or Rectangle. macOS Sequoia finally brings native window tiling — and it's surprisingly powerful.
How It Works
- Drag to edge: Drag a window toward the edge or corner of your screen. A blue preview appears showing where the window will snap. Release to tile it there.
- Hold Option while dragging: This enables edge-snapping even without moving all the way to the edge
- Green button menu: Click and hold the green traffic light button on any window to see tiling options including halves, thirds, quarters, and corners
- Keyboard shortcut: Hold
Control + Optionand use arrow keys to move a window to different screen positions
You can also tile two apps into a split view by dragging one tiled window into the other. It's not quite as fast as Magnet, but for basic tiling needs it works great and requires no third-party software.
To configure tiling behavior, go to System Settings > Desktop & Dock and scroll down to the Windows section.
2. iPhone Mirroring: Use Your iPhone on Your Mac
This is the feature that surprised me most with Sequoia. iPhone Mirroring lets you see and fully control your iPhone — screen, apps, touch interactions — right on your Mac. Your iPhone stays locked and private while you do this.
How to Set It Up
- Your Mac and iPhone need to be signed into the same Apple ID
- Both must have Bluetooth and Wi-Fi enabled
- Your iPhone needs to be nearby and locked
- Open iPhone Mirroring from your Applications folder or Dock
- Authenticate once with Touch ID or your Mac password
After setup, it's one click to bring your iPhone's screen up on your Mac. You get full touch control — tap, swipe, pinch — using your mouse or trackpad. Notifications from your iPhone also appear in macOS, and you can click them to interact right there in the Mirror window.
Practical use: Respond to texts without picking up your phone, check a mobile app you don't have a Mac version of, or manage your iPhone during a screen recording or presentation — all without breaking your flow.
3. The New Passwords App
macOS Sequoia ships with a standalone Passwords app — your iCloud Keychain data has been moved into a dedicated app that's now much easier to access and manage.
What the Passwords App Includes
- All your saved website and app passwords
- Passkeys — the next-generation login credentials that replace passwords entirely for supported sites
- Wi-Fi passwords — finally, a way to look up the Wi-Fi password you saved years ago
- Verification codes (2FA codes) — stored right alongside the password they protect
- Security alerts for passwords that have appeared in data breaches or are too weak
Open it from Applications > Passwords, or search for it in Spotlight. Sign-in with Touch ID, and your entire password library is there. It also syncs across your iPhone and iPad, and there's a Windows app via iCloud for Windows for those who work across platforms.
For an in-depth look at passkeys and why they matter, check out Apple's passkeys developer documentation — it's actually quite readable.
4. A Completely Redesigned Calculator
The Calculator app hasn't had a meaningful update in years. Sequoia changes that with a ground-up redesign that's genuinely useful.
- Math Notes integration: You can type equations in the Notes app and the Calculator will solve them live. Type "tip = 18% × $47.50 =" and it calculates right in your note
- History panel: A scrollable history of every calculation you've done in the current session, so you don't lose track
- Unit conversion: Built-in conversions for currency, length, temperature, weight, and more — no more Googling "100 kg in lbs"
- Scientific and programmer modes: Still there, but now more easily accessible via the sidebar
The Math Notes feature works in the Notes app directly — open a new note, type a math expression with an equals sign, and the result populates automatically. Change a number and every dependent result updates. It's like a very lightweight spreadsheet embedded in Notes.
5. Highlights in Safari
Safari's new Highlights feature uses on-device intelligence to identify and surface the most useful information on a webpage without you having to read the whole thing.
When you land on a page — especially a business listing, article, or product page — Safari may show a subtle highlight button in the Smart Search bar. Click it to see surfaced details like:
- Business name, address, phone number, and hours
- Maps directions link
- Summary of the article's key points
- Links to related content
It's subtle but genuinely useful when you're doing quick research. Combine it with Reader Mode (which now has AI-generated summaries) and Safari becomes a much smarter research tool.
6. Improved Video Conferencing: Background Removal and Presenter Overlay
Sequoia brought two new video tricks that work system-wide — meaning they work in Zoom, Teams, Google Meet, FaceTime, and any other video app, not just Apple's own software.
- Background Replacement: In any video call, click the Video Effects button in the menu bar (it appears when your camera is active) to add a virtual background or blur. No need to find the option inside each individual app.
- Presenter Overlay: New in Sequoia, this lets you appear as a floating overlay in front of your shared screen during presentations — either as a small bubble or a larger inset. It looks much more polished than the typical screen-share-plus-webcam setup.
Access these by clicking the green video effects pill button that appears in the menu bar when your camera is on, or through Control Center > Video Effects.
7. Desktop Widgets Are Now Interactive
Widgets on the macOS desktop have been around since Sonoma, but Sequoia makes them interactive — meaning you can check off a reminder, control music playback, or tap a Home button without opening the app first.
Right-click your desktop and choose Edit Widgets to add or rearrange them. Useful interactive widgets include:
- Reminders — check off tasks directly from the desktop
- Home — toggle lights and accessories without opening the Home app
- Music / Podcasts — playback controls right on your desktop
- Calendar — see today's events and click to open them
iPhone widgets are also available if you have iPhone Mirroring set up — you can pull widgets from your iPhone apps and display them on your Mac desktop even if the Mac app doesn't have a widget.
8. Keyboard Shortcuts Got More Flexible
macOS Sequoia quietly improved the customization of keyboard shortcuts. You can now assign shortcuts to more actions than before, and there's a new App Shortcuts section in System Settings that makes it easier to create custom shortcuts for any menu item in any app.
Go to System Settings > Keyboard > Keyboard Shortcuts > App Shortcuts. Click the + button, choose an app, type the exact name of a menu item, and assign your key combo. This is particularly useful for actions buried in submenus that you use constantly.
9. Improved Focus Modes
Focus modes have been around since Monterey, but Sequoia adds smarter automation. You can now set Focus filters that adjust:
- Which Mail accounts are active (e.g., hide personal email during Work Focus)
- Which Calendar accounts show events
- Safari's Tab Group that opens automatically
- The wallpaper on your Mac and connected iPhone
Set up Focus modes in System Settings > Focus. The real power comes from combining a Focus mode with automation — you can trigger it based on time of day, location, or when a specific app is open.
10. AirPlay to Mac: Use Your Mac as a Speaker or Display
Sequoia continues the AirPlay to Mac feature, which lets any AirPlay-compatible device send audio or video to your Mac. This means your iPhone can use your MacBook's superior speakers for music, or your Apple TV can send a video to your Mac's display.
Enable it in System Settings > General > AirDrop & Handoff and toggle on AirPlay Receiver. You can restrict it to devices on the same Wi-Fi network or require a password.
11. Quick Look Now Shows More File Info
Press the Space bar on a file in Finder to Quick Look it — that hasn't changed. But Sequoia improves what Quick Look shows you:
- Better metadata display for photos (lens, ISO, shutter speed)
- Improved PDF previews with page navigation
- Live previews of code files with syntax highlighting
It's a small thing, but if you live in Finder, Quick Look is one of the most-used features on a Mac and these improvements add up.
12. Screen Recording Privacy Improvements
Sequoia adds a long-overdue privacy improvement: when an app requests screen recording access, it can now be granted access to only a specific window rather than your entire screen. This is huge for privacy when using screen-share-based tools that traditionally required seeing your whole screen.
You'll also see clearer indicators in the menu bar when any app is recording your screen, capturing your mic, or accessing your camera — making it easier to know exactly what's running and reviewing it in System Settings > Privacy & Security.
Getting the Most Out of macOS Sequoia
The best way to discover what's new in Sequoia is simply to explore — Apple's official macOS Sequoia features page has a comprehensive rundown, and the Apple Support macOS section has detailed how-to articles for most of the features above.
The features that will change your daily workflow most depend on how you use your Mac. For me, Window Tiling and iPhone Mirroring are the daily drivers. The Passwords app is a genuine replacement for my old password manager. And Math Notes in the Calculator has saved me more time than I expected.
