Most people use maybe 20% of what macOS can do. The rest sits there, waiting to be discovered — buried in System Settings or hidden behind a keyboard shortcut nobody told you about.
Here are 10 features and habits that will genuinely save you time. No fluff, just things you can set up in the next few minutes and benefit from immediately.
1. Hot Corners — Instant Actions Without Touching Your Keyboard
Open System Settings → Desktop & Dock → Hot Corners (bottom of the page). Assign actions to each corner of your screen. When you move your cursor to that corner, the action triggers instantly.
My recommendation: bottom-right for Quick Note, top-right for Mission Control, bottom-left for Lock Screen.
Why it matters: Locking your screen before walking away from your desk becomes a flick of the wrist. Opening Mission Control to find a window takes half a second. It's one of those things that feels insignificant until you realize you do it 40 times a day.
2. Spotlight Can Do Math, Conversions, and Definitions
You probably use Spotlight (Cmd+Space) to open apps. But it also handles math (234 * 1.19), unit conversions (45 USD in EUR), dictionary lookups, and weather. Type a contact's name and you'll see their phone number and address right there.
If you want to go further, look at Raycast — it replaces Spotlight entirely and adds clipboard history, snippets, window management, and hundreds of extensions. It's free for personal use.
3. Focus Modes — Not Just Do Not Disturb
Go to System Settings → Focus. You'll find "Do Not Disturb," but the real power is in creating custom Focus modes.
Set up a Work focus that only allows notifications from Slack and your calendar. Create a Writing focus that silences everything. The trick: tie each Focus mode to an automation. You can set Work to activate automatically when you open a specific app, connect to your office Wi-Fi, or arrive at a location.
Your Focus syncs across all Apple devices. Turn it on on your Mac and your iPhone goes quiet too.
4. Quick Actions in Finder — Batch Operations Without Extra Apps
Select one or more files in Finder, then right-click and look at Quick Actions. You can rotate images, convert image formats, trim videos, mark up PDFs, and merge them into a single document — all without opening a separate app.
The hidden gem: you can create your own Quick Actions using the Shortcuts app. Build a shortcut that resizes images to a specific width, then it shows up in that right-click menu for any image file. Very useful for anyone who regularly preps images for the web.
5. Preview Is More Powerful Than You Think
Preview (the default PDF and image viewer) can do a shocking amount of work:
- Sign documents — Tools → Annotate → Signature. Create a signature once, then drop it into any PDF.
- Fill PDF forms — Click on form fields and type directly. Works with most PDFs.
- Remove image backgrounds — Open an image, use the Instant Alpha tool (magic wand icon in the markup toolbar) to select and delete backgrounds.
- Batch resize images — Select multiple images in Finder, open them all in Preview, then select all thumbnails in the sidebar and go to Tools → Adjust Size.
Most people install third-party apps for things Preview handles natively.
6. Stage Manager — For People Who Drown in Windows
If you tend to have 15 windows open and lose track of everything, try Stage Manager. Turn it on via Control Center in the menu bar (or System Settings → Desktop & Dock → Stage Manager).
It groups your windows into sets on the left side of your screen. Click a group and it comes to the front, pushing the others aside. It's not for everyone — some people hate it — but for those who work in distinct contexts (research, writing, communication), it's a cleaner alternative to juggling windows manually or maintaining seven desktops in Mission Control.
7. Text Replacement — System-Wide Snippets
Go to System Settings → Keyboard → Text Replacements. Add abbreviations that expand to full text. For example:
@@→ your email addressaddr→ your full mailing addresszz→ "Thanks, talk soon!"
These work everywhere — Mail, Messages, Slack, any text field. They sync across your iPhone and iPad too. For short, repetitive things you type daily, this alone saves minutes.
8. Schriftly — AI Text Editing Anywhere on Your Mac
Here's one that's not built into macOS but works like it is. Schriftly is a lightweight menu bar app that lets you transform text with AI in any application.
Select a rough draft in an email, a Slack message, or a Google Doc. Press Option+F. The text is rewritten instantly — grammar fixed, tone polished, phrasing tightened. No copy-pasting into ChatGPT, no browser tab switching, no waiting for a web app to load.
It works in every app because it operates at the system level. You can bring your own API key for a one-time $39 purchase, or use the hosted plan at $9/month.
If you write a lot — emails, docs, messages — and you want the editing to happen where you already are instead of in a separate tool, it's worth a look.
9. Automator & Shortcuts — Your Personal Assembly Line
The Shortcuts app (shipped with macOS since Monterey) lets you chain actions together: rename a batch of files, resize and convert images, send a templated email, extract text from images, or generate calendar events from text.
A few practical ones to build:
- Meeting prep: A shortcut that opens your calendar, Notion, and Zoom with one click.
- End of day: A shortcut that closes all apps, sets Focus to "Personal," and opens Music.
- File cleanup: A shortcut that moves all screenshots older than 7 days from your Desktop to a specific folder.
You can trigger Shortcuts from the menu bar, a keyboard shortcut, or even Siri. If you've never opened the Shortcuts app, spend 20 minutes with it. You'll find at least one workflow that saves you real time.
10. Universal Clipboard and Handoff — Move Between Devices Seamlessly
If you have an iPhone and a Mac signed into the same Apple ID with Bluetooth and Wi-Fi on, Universal Clipboard is already active. Copy text or an image on your iPhone, then Cmd+V on your Mac. It just works.
Handoff extends this further. Start writing an email on your iPhone, and a small icon appears in your Mac's Dock letting you pick up where you left off. Works with Safari tabs, Notes, Maps, Reminders, and many third-party apps.
The less obvious trick: use your iPhone as a document scanner via Continuity Camera. In Finder or any supported app, right-click and choose "Import from iPhone → Scan Documents." Your iPhone's camera opens, you scan the page, and it appears on your Mac as a PDF. No scanning app needed.
None of these tips are complicated. Most take under five minutes to set up. The difference between someone who feels fast on their Mac and someone who doesn't usually comes down to knowing these features exist in the first place.
