Use Command-Space before opening Safari. Spotlight is faster than remembering where you put things.
Command-Shift-4 is a screenshot tool pretending to be a keyboard shortcut.
Command-Tab switches apps. Staring at the Dock is not an equivalent workflow.
Command-` switches windows in the current app. macOS hid it in plain sight.
Press Space on a selected file for Quick Look. Opening the full app was never required.
Hold Option while clicking the Wi-Fi icon for extra network details. Tiny menu, large confidence boost.
Use Command-Shift-5 for screenshots and screen recording. No extra ceremony required.
Command-W closes the current window. Command-Q is for when you actually mean goodbye.
Press Command-Option-Esc when an app freezes. Negotiation is rarely productive.
Use Finder tags when folders start reproducing. Color-coding is not a filing system, but it helps.
Pin frequently used Finder folders to the sidebar. Memory is a poor indexing strategy.
Use Shift-Command-N in Finder to create a folder instantly. Your mouse has other responsibilities.
Hold Command while clicking a Finder title to reveal the folder path. Now you can prove where you are.
Use Quick Look on images, PDFs and documents before launching anything. Preview is often enough.
Drag files directly from Spotlight results. Search first, then move. Revolutionary concept.
Use Focus modes to silence notifications during work. The internet will survive your absence.
Set default apps for common file types once. Choosing the same app manually forever is not customization.
Use Stage Manager when windows become a small civilization. It is not magic, but it is less chaotic.
Press Command-H to hide the current app. Sometimes closing is too dramatic.
Use text replacement for phrases you type repeatedly. Let macOS do the repetitive bit.
Check Login Items if your Mac takes forever to wake up. Half of that startup parade probably volunteered.
Use AirDrop for nearby file transfers instead of emailing yourself attachments like it is 2009.
Learn three shortcuts well. Knowing thirty badly is mostly a collection hobby.
Use Command-F before scrolling through a long document. The page has a search box for a reason.
Command-A selects everything in the current context. Context remains important.
Command-Z is usually cheaper than starting over. Undo is one of civilization's better inventions.
Use Command-Shift-G in Finder to jump directly to a folder path. Typing is faster than sightseeing.
Press Command-L in Finder to focus the location field when supported. The filesystem is addressable.
Use Option-Command-V in Finder to move copied files instead of creating duplicates. Less clutter, fewer regrets.
Hold Option while dragging a file to create a copy. One modifier, one duplicate.
Use Command-I to inspect file information without opening it. Metadata has its moments.
Sort Finder by Date Modified when searching for something you just changed. Recent memory is surprisingly useful.
Use List View when filenames matter more than thumbnails. A folder is not a photo gallery.
Use Column View when you need to understand folder hierarchy. Context beats clicking backward repeatedly.
Use Gallery View for visual assets. Pick the view that matches the job.
Add frequently used locations to Finder Favorites. Your future self will approve.
Use iCloud Drive for files that need to follow you between Apple devices. Local-only is not always convenient.
Keep large archives out of your Desktop. The Desktop is a workspace, not a warehouse.
Use Desktop and Documents in iCloud Drive only if that workflow suits you. Synchronization is a choice, not a moral obligation.
Empty Trash when you actually need the storage. Digital rubbish rarely leaves by itself.
Check About This Mac storage recommendations before deleting random files. Random deletion is not optimization.
Use Activity Monitor when something feels suspiciously slow. Guessing is slower.
Sort Activity Monitor by CPU to find unusually busy processes. Your Mac is willing to explain itself.
Check Memory Pressure before blaming one application. RAM usage is more nuanced than a single percentage.
Use Force Quit only when an app genuinely stops responding. It is a fire extinguisher, not a launch button.
Restart the Mac when a problem has become strangely complicated. Rebooting remains undefeated in several categories.
Install system updates deliberately, especially before important travel or presentations. Timing is a feature.
Keep enough free disk space for macOS and your applications. A completely full drive is not an achievement.
Use Time Machine for backups. Future you has poor negotiating power after data loss.
Verify that backups actually complete. A backup you never checked is a hopeful theory.
Keep a second backup for irreplaceable work when appropriate. One copy is not a strategy.
Use Screenshot options to choose where captures are saved. The Desktop does not need every screenshot ever taken.
Copy text from images with Live Text when supported. Re-typing is sometimes an unnecessary internship.
Use Preview to annotate PDFs instead of printing them first. Paper is optional.
Sign documents in Preview when supported. The printer can remain unemployed.
Combine or reorder PDF pages in Preview. Acrobat is not the only adult in the room.
Use Markup for quick image annotations. Editing does not always require a production suite.
Use Dictionary lookup from supported text. The answer may already be on the Mac.
Press Control-Command-Space to open the emoji and symbol viewer. Typography has a toolbox.
Use keyboard text replacements for addresses, signatures, and boilerplate. Repetition belongs to machines.
Use Dictation for longer passages when typing becomes the bottleneck. Your voice is another input device.
Use Universal Clipboard between nearby Apple devices when configured. Copy on one device, paste on another.
Use Handoff when continuing supported tasks between Apple devices. Context can travel with you.
Keep Bluetooth settings tidy by removing devices you no longer use when necessary. Your Mac remembers too much.
Use Control Center for common toggles instead of digging through Settings. The menu is there to save time.
Customize Control Center around actions you actually perform. A control you never use is decorative.
Use hot corners if you like pointer-based shortcuts. Four corners, surprisingly many opinions.
Use Mission Control to see all open windows at once. Your desktop may have more inhabitants than expected.
Create additional Spaces for distinct contexts. One desktop does not need to contain your entire life.
Name Spaces by purpose when useful. “Desktop 7” is not a meaningful project plan.
Move windows between Spaces instead of duplicating apps unnecessarily. Organization is cheaper than repetition.
Use full-screen mode for focused tasks when it genuinely helps. Bigger is not automatically better.
Tile windows when comparing documents. Your eyes prefer stable geometry.
Use a trackpad gesture to reveal Mission Control. Gestures become useful once they become muscle memory.
Learn one Finder shortcut every few days. Slow accumulation beats shortcut tourism.
Use Command-K in supported apps to insert a link. Linking can be faster than formatting manually.
Use Command-B, Command-I, and Command-U for common formatting in supported apps. Tiny shortcuts, repeated savings.
Press Escape to cancel many transient actions. Sometimes the fastest command is never mind.
Use Tab to move between fields in forms. Clicking every box individually is expensive in aggregate.
Use Shift-Tab to move backward through fields. There is an exit route.
Press Return when a selected Finder item is ready for renaming. No context menu expedition required.
Use Command-Delete to move selected files to Trash. The keyboard already knows where rubbish goes.
Use Option-Command-D to show or hide the Dock. More screen space, fewer distractions.
Use Control-Command-F for full screen in supported apps. One shortcut can reclaim a lot of pixels.
Use Command-Plus and Command-Minus to adjust zoom in supported apps. Tiny text is not a productivity metric.
Use Safari profiles to separate contexts when appropriate. Work and weekend browsing can stop sharing a drawer.
Use tab groups when a project needs a stable collection of pages. Fifty loose tabs are not a knowledge base.
Pin tabs you return to constantly. A pinned tab is a bookmark with commitment issues.
Use Safari Reader when supported to reduce visual noise. Sometimes the article is enough.
Use Passwords to manage saved credentials rather than keeping them in Notes. Convenience should still have structure.
Use passkeys where supported. Fewer passwords means fewer opportunities to forget one.
Use iCloud Keychain across Apple devices when appropriate. Reusing passwords is not synchronization.
Review privacy permissions when an app asks for something unexpected. Access requests deserve context.
Check Location Services permissions periodically. Not every app needs to know where you are.
Use Screen Time when you want data instead of vague guilt. Numbers are occasionally more persuasive.
Turn off unnecessary notifications at the source. Silence is more effective when configured upstream.
Use Focus filters where supported to show only relevant information. Less noise can be a feature.
Keep the menu bar readable by hiding icons you never use when possible. The top edge is finite.
Use a consistent naming convention for projects and files. Search works better when humans cooperate.
Archive completed projects instead of leaving everything active. Your filesystem also benefits from retirement.
