Screenshots & Screen Recording
on Your Mac, in Plain English

The one small skill that solves a hundred big frustrations

Half of tech help is figuring out what the screen actually said. Something appears, someone reaches for a pen, and the message vanishes before the first word is written down — and then the description over the phone becomes "it said something about an error." That isn't enough to fix anything. Your Mac has had the answer built in for years: press three keys and it photographs the screen, exactly, in about one second.

Once you can take a screenshot, error messages get captured letter for letter instead of half-remembered. A frightening pop-up becomes evidence you can show someone instead of a bad memory. And "I can't describe it, you'll have to come over" turns into a two-minute email. Nothing to buy, nothing to install, nothing to sign up for. This page teaches the essentials; the free 25-page PDF walks through all of it in large print, at kitchen-table pace.

The three shortcuts that do everything

1. Shift + Command + 3 — a picture of the entire screen. Press all three together, like a chord on a piano, not one after another. You'll hear a shutter click.
2. Shift + Command + 4 — your pointer turns into crosshairs. Press and hold the mouse or trackpad button, drag a box around just the part you want, then let go. This is the one to live on.
3. Shift + Command + 4, then tap the Space bar — the pointer becomes a little camera. Click any window to capture that window alone, edges clean.
4. Shift + Command + 5 — opens the Screenshot toolbar along the bottom of the screen, where the video-recording buttons and all the settings live.
5. Changed your mind mid-drag? Press Esc and nothing is captured. Nothing you do here can break anything.

Where did my screenshot go?

Your desktop — the background behind your windows — unless you've changed the setting. Pictures are named Screenshot followed by the date and time and end in .png; recordings are named Screen Recording and end in .mov. (On older versions of macOS the name reads "Screen Shot" with a space.) Can't see the desktop under all those windows? Open Finder and click Recents in the sidebar — your newest capture is at the top. And if screenshots seem to have stopped appearing altogether, press Shift + Command + 5, click Options, and check that Save to says Desktop and not Clipboard. That one setting causes most of the "my screenshots disappeared" calls I get.

The little preview in the corner — and drawing on it

• After every capture a small preview floats in the bottom-right corner for a few seconds. Apple calls it the floating thumbnail.
• Do nothing and it saves itself. That's the right answer most of the time.
• Drag it straight into an email, a Messages conversation, or a document — no saving, no finding, no attaching. Fastest way there is.
• Click it to open Markup, where you can draw a red circle, add an arrow, type a note, magnify a spot with the Loupe, or crop away everything that doesn't matter. Click Done when you're finished, or Revert to start over.
• Vanishing too fast? Rest your pointer on top of it — hovering keeps it on screen until you act.
• One red circle and one short note beats a picture covered in arrows. The person helping you is looking for one thing.

Recording a video of your screen — with your voice

1. Press Shift + Command + 5 and choose one of the three recording buttons (the ones with a small dot in the corner). Record Selected Portion is usually kindest — it keeps the file small and your other windows private.
2. Click Options, and under Microphone click your Mac's built-in microphone so a checkmark appears. Now you can narrate. Choosing None turns sound back off.
3. Click Record, then do the thing that goes wrong — slowly, talking as you go.
4. To stop: click the small stop button in the menu bar at the very top of the screen, or press Command + Control + Esc, which always works.
5. Honest limitation: as of mid-2026 the built-in recorder captures your voice through the microphone, not the sound coming out of your Mac's own speakers. If a pop-up is talking or chiming, just describe out loud what you're hearing.

A frightening pop-up? Capture it, close it, tell someone

1. Capture it first. Shift + Command + 4, drag a box around the whole warning. Photographing a pop-up is completely safe — it cannot let anything in.
2. Don't click anything inside it. Not OK, not Cancel, not Scan Now. Inside a fake warning, every button is the same button.
3. Close it. Command + W closes the window; Command + Q quits the browser entirely. If the screen seems locked full-screen, press Esc first.
4. Never call the number. Apple doesn't put phone numbers in warnings and doesn't cold-call about your computer. The pop-up can't hurt you sitting there — the harm starts with the phone call.
5. Show the picture to a person the same day — family, a neighbor, or me. Thirty seconds of a second opinion settles it, and there's no judgment in asking.

Check the edges before you send

A screenshot captures the whole box you drew, including the things at the edges you weren't thinking about — account numbers at the top of a bank page, a password shown by the little eye icon, a verification code, a Medicare number, or other people's email addresses in an open list behind the window. Two habits prevent all of it: use Shift + Command + 4 and draw a tight box, and glance at the floating preview before you send. Need to hide one line? Open Markup, drop a filled black rectangle over it. And remember — nobody legitimate ever needs a screenshot of your password or a texted code. Not Apple, not your bank, not me.

Emailing an error to family — or to Bill

1. Capture it before you click OK. The button makes the message vanish forever. Picture first, button second.
2. Open a new email and write three short lines: what you were doing, what happened, and what you already tried.
3. Add the picture — drag the floating preview in, drag the file in from the desktop, or press Command + V if you copied it (hold Control with any shortcut to copy instead of save).
4. Send it. To me: bill@billshometech.com, with "error" in the subject and your phone number at the bottom.
5. Sending a video instead? Recordings are big, and many email systems refuse anything over about 20–25 MB. Apple Mail will offer Mail Drop, which sends a download link — say yes. Or AirDrop it, or trim it shorter first.

Every method at a glance

• Shift + Command + 3 — the entire screen.
• Shift + Command + 4 — drag a box around any part.
• Shift + Command + 4, then Space — one window on its own.
• Shift + Command + 5 — the toolbar: six capture and record tools plus Options.
• Control + any of the above — copies it for pasting instead of saving a file.
• Command + V — pastes the copy into an email or document.
• Command + Control + Esc — stops a screen recording.
• Nothing happening at all? Check System Settings > Keyboard > Keyboard Shortcuts > Screenshots — and make sure you're pressing the keys together, not one after another.

Why I wrote this

Half of tech support is figuring out what the screen actually said — and a screenshot skips that half entirely. That's why I teach this on so many visits around Portage County, and why I finally wrote it down properly. I print these guides in large type because a skill this useful shouldn't be locked behind squinty text. And I'll be honest about the economics: I'd rather someone email me a picture and save the $99 than pay me to drive out and read an error message off the screen. — Bill
