I.T. Savvy Mac Tips


🔦1. Use Spotlight as a "Super-Search" Tool

🩳 Shortcut: `Command + Space`

Most people use Spotlight to find a lost file, but it’s much more than a search bar. Try typing these directly into the search box:

  • Quick Maths: Type `15% of 120` or `24 * 7` for an instant answer.

  • Currency Conversion: Type `100 USD to AUD` to see the current exchange rate.

  • Weather: Type `Weather in Brisbane` for a quick forecast.

  • Launch Apps: It’s often faster than clicking through your Dock!


🤳2. Take Screenshots Like a Pro

Don’t just capture the whole screen and crop it later. Use these specific shortcuts:

  • `Shift + Command + 4`: Turns your cursor into a crosshair so you can select a specific area.

  • `Shift + Command + 4`, then Space: Hover over a specific window (like a web browser or a folder) and click to capture just that window with a nice clean shadow.

  • Pro Tip: Press `Shift + Command + 5` and click Options to change where your screenshots are saved (e.g., to a dedicated "Screenshots" folder) so your Desktop stays tidy.


📂 3. Use Quick Look to Preview Files Instantly

🩳 Shortcut: Select a file and press the Space bar.

This is one of the best "hidden" features of macOS. You can view PDFs, photos, and even play videos without ever opening an app.

  • The Bonus: You can even do basic edits, like rotating an image or trimming a video, directly inside the preview window.


👽4. Free Up Space with Built-In Tools

Go to: `Apple Menu > System Settings > General > Storage`

Before you pay for "Mac Cleaner" software, check here first. macOS has built-in tools to:

  • Optimise Storage: Automatically move old files to iCloud when space is low.

  • Empty Bin Automatically: A "set and forget" way to keep things clean.

  • Review Large Files: Easily find and delete those giant downloads you forgot about.


🪓 5. Use Split View for Easy Multitasking

If you’re constantly clicking between an email and a spreadsheet, this is for you.

  • How to do it: Hover your mouse over the **green full-screen button** in the top-left of any window. Choose Tile Window to Left/Right of Screen.

  • To Exit:** Just press the `Esc` key or click the green button again.


🔥6. Use Hot Corners to Speed Up Daily Tasks

Hot Corners turn the four corners of your screen into "magic buttons."

  • Setup: `System Settings > Desktop & Dock > Hot Corners`.

  • I.T. Savvy Suggestion: Set the bottom-left corner to Desktop (to quickly clear everything away) and the top-right to Mission Control (to see all open windows).


🗣️ 7. Dictation: Talk Instead of Typing

🩳 Shortcut: Press the Microphone key (usually `F5`) or double-tap the `Control` key.

If you have a long email to write and your fingers are tired, just say it out loud. Your Mac is surprisingly good at transcribing your voice into text in real-time.


😣 8. Focus Modes: Get Some Peace and Quiet

Where to find it: Click the Control Centre icon (the two small sliders) in the top-right menu bar and select Focus.

Use "Do Not Disturb" or create a custom "Work" mode to silence those pings and dings while you’re trying to concentrate. You can even set it to turn on automatically during your work hours.


🗂️ 9. Use AirDrop for Instant Sharing

Stop emailing files to yourself! If you have an iPhone or another Mac nearby, AirDrop is the fastest, safest way to move photos and documents.

  • How: Right-click any file, choose Share, then AirDrop.


🤨 10. Use the Built-In Emoji & Symbol Picker

🩳 Shortcut: `Control + Command + Space`

Want to add a bit of personality to an email or name a folder with an icon? This shortcut opens a full library of emojis and symbols anywhere you can type.


🔮 11. Preview: The PDF Powerhouse

Most people think they need to pay for Adobe Acrobat to handle PDFs. You don’t! The built-in Preview app can:

  • Sign documents: Use your trackpad or iPhone to create a digital signature.

  • Merge PDFs: Just drag and drop one PDF file into the sidebar of another.

  • Protect: Add a password to sensitive documents.


⛑️ 12. The "Friday Afternoon" Maintenance Habit

You don’t need "cleaner" apps—in fact, we usually recommend avoiding them! Instead, keep your Mac fast with these three simple habits:

1. Restart once a week: We call it the "Friday Restart." It clears out the digital cobwebs and keeps things snappy.

2. Close unused tabs: If you have 50 tabs open in Chrome or Safari, your Mac is working overtime.

3. Clear your Downloads folder: It’s the #1 place where digital clutter lives.
