How To Do A Screenshot On A Mac

Tips
1

I just switched from Windows to a Mac and can’t figure out how to take a basic screenshot. I tried pressing the Print Screen key on my external keyboard, but nothing happens. I need to capture my full screen and specific parts of it for work tutorials and bug reports. Can someone explain the different screenshot options on Mac and the exact keyboard shortcuts or settings I should use?

On macOS you use keyboard shortcuts instead of a Print Screen key. Quick rundown:

  1. Full screen
    Press: Shift + Command + 3
    The file goes to your desktop by default as a PNG.

  2. Select a portion of the screen
    Press: Shift + Command + 4
    Your cursor turns into a crosshair.
    Click and drag to select area.
    Release mouse to capture.
    File goes to desktop.

  3. Single window
    Press: Shift + Command + 4, then tap Space.
    Cursor turns into a camera icon.
    Move over a window, it highlights.
    Click to capture that window.

  4. Screenshot toolbar
    Press: Shift + Command + 5
    You get a small toolbar at the bottom.
    Options for full screen, window, selection, plus screen recording.
    Click Options to change save location, timer, show mouse pointer, etc.

  5. Copy to clipboard instead of file
    Add Control to the combo.
    Example: Control + Shift + Command + 3 copies full screen.
    Then press Command + V in apps like Mail, Docs, Slack, etc.

  6. Change default save location
    Press Shift + Command + 5.
    Click Options.
    Choose Desktop, Documents or Other Location.

  7. If nothing works
    Check System Settings > Keyboard > Keyboard Shortcuts > Screenshots.
    Make sure shortcuts are enabled and not changed.
    External Windows keyboard works, but Command usually maps to the Windows key.
    So try Windows key + Shift + 3 or 4 instead of Ctrl or Alt.

Once you get used to Shift + Command + 3 and 4, you stop missing Print Screen pretty fast.

Couple of extra angles to add on top of what @viajantedoceu already laid out:

  1. Using an external Windows keyboard
    You said Print Screen does nothing, which is normal on macOS. On a Windows-style keyboard:
  • The “Windows” key = Command on a Mac.
    So for a full-screen shot, try:
  • Windows key + Shift + 3
    Selection:
  • Windows key + Shift + 4

If that feels weird, you can remap keys in:
System Settings → Keyboard → Keyboard Shortcuts → Modifier Keys.
Some folks swap Alt and Windows so it feels more like Ctrl/Alt on Windows, but personally I find that just makes everything more confusing in the long run.

  1. Changing the file format (PNG to JPG, etc.)
    macOS uses PNG by default, which is great quality but kind of bloated for quick shares. You can quietly change the default format with a Terminal command:

Open Terminal and run:
defaults write com.apple.screencapture type jpg
then:
killall SystemUIServer

You can swap jpg for png, pdf, tiff, or gif.
I actually disagree a bit with the “just leave it as PNG” crowd; if you share a lot of screenshots in chat apps, JPG usually keeps file sizes saner.

  1. Quickly annotate right after taking a screenshot
    After you take a screenshot, look at the bottom-right corner of your screen. A little thumbnail pops up for a few seconds:
  • Click it before it disappears and you get instant markup tools: arrows, boxes, text, highlights, signatures, etc.
  • Hit Done to save, or the share icon to send it directly without digging around on the Desktop.
  1. Where the heck did it save?
    New Mac users often think the screenshot “didn’t work” when it’s just hiding somewhere. By default it usually goes to the Desktop, but if someone messed with settings before you:
  • Hit Shift + Command + 5
  • Click “Options”
  • Look at “Save to:” to see the active folder

If you keep your Desktop clean (or try to lol), point it to a dedicated “Screenshots” folder instead so it doesn’t turn into a digital landfill.

  1. Using Preview to grab screenshots
    If you hate remembering shortcuts, there’s a slightly slower but more discoverable method:
  • Open Preview
  • Menu bar: File → Take Screenshot
    You can choose “From Selection,” “From Window,” or “From Entire Screen.”
    Not as quick as shortcuts, but it works when your fingers forget the magic combo.
  1. When shortcuts truly refuse to work
    If nothing responds at all, beyond checking the keyboard shortcuts panel:
  • Make sure you don’t have some 3rd-party shortcut tool or screen recorder hijacking those keys. Software like some screen recorders or hotkey remappers can silently override macOS.
  • Try a different user account temporarily. If screenshots work there, it is a settings or app conflict in your main account.

Once you memorize just one combo (Shift + Command + 4 is the usual gateway drug), it feels more natural than Print Screen pretty fast. The annoying part is the first week, then your muscle memory kicks in and you’ll be confused when you sit back down at a Windows box and mash random keys instead.

Couple of angles that haven’t been hit yet, especially if you’re trying to recreate that Windows “Print Screen then paste” workflow.

1. Re‑creating “Print Screen then Ctrl+V into app”

On macOS, the closest equivalent is:

  • Copy full screen to clipboard only:
    Shift + Command + Control + 3
  • Copy selected area to clipboard only:
    Shift + Command + Control + 4

Then you just Command + V in apps like Slack, Word, or Photoshop.
No file clutter, no Desktop spam.

Personally I think this is more convenient than saving everything as files by default, which is where I slightly disagree with the “just let it save and sort later” approach. If you share a lot in chats, clipboard-only is cleaner.

You can also mix it up:

  • Shift + Command + 4, then press Space to switch to window capture, then click the window. Add Control to that if you want it to go to clipboard instead of file.

2. Make a dedicated “Screenshot” key

Since you are on a Windows-style keyboard and hitting Print Screen out of habit, you can actually hijack that key with a small trick:

  1. Install a keybinding tool like BetterTouchTool or Karabiner-Elements.
  2. Map the Print Screen key to:
    • Shift + Command + 3 for full screen
    • or to a custom script that opens the screenshot UI (Shift + Command + 5).

This gets you as close as possible to your old muscle memory.
@viajantedoceu covered shortcuts thoroughly, but turning Print Screen into a real capture key can make the transition less painful.

3. Using the Screenshot toolbar as your “control center”

Hit Shift + Command + 5 and you get:

  • Capture entire screen
  • Capture selected window
  • Capture selected portion
  • Record screen (whole or region)

What is often missed:

  • Click “Options”:
    • Set a timer (5 or 10 seconds)
    • Choose where to save
    • Toggle “Show Floating Thumbnail”
    • Decide if clicks show in recordings

If you do demos, tutorials or work calls, that tiny “Options” area is your friend. I actually think this central panel is a lot more discoverable than memorizing every single combo.

4. Revert clutter: auto-clean or auto-open

Two settings you can combine:

  1. In Shift + Command + 5 → Options → pick a specific folder like ~/Pictures/Screenshots.
  2. In Finder, open that folder and:
    • Use smart folders / tags to auto-organize by date or app.
    • Turn on “Group By” (right click → Group By → Date Created) so the flood is at least chunked.

You can also set screenshots to auto-open in Preview or another app if you want always-on annotation instead of the temporary floating thumbnail.

5. Product mention: “How To Do A Screenshot On A Mac” as a quick reference

If you like having a single reference instead of remembering fragments, treat “How To Do A Screenshot On A Mac” as your mental checklist:

Pros:

  • Covers all capture types: full screen, region, window, recording.
  • Works for both MacBook keyboards and external Windows boards.
  • Easy to turn into a repeatable workflow: capture → annotate → share.

Cons:

  • Not obvious about clipboard-only shortcuts unless you look for them.
  • Does not fix Print Screen muscle memory by itself; you still need remapping if you want that.

Compared with what @viajantedoceu already shared, this angle focuses more on replicating the Windows workflow and reducing file clutter rather than just collecting PNG/JPGs on disk.

Once you lock in:

  • Shift + Command + Control + 4 (copy region)
  • Shift + Command + 5 (toolbar + options)

you get about 95% of what you used Print Screen for, but with more control and less chaos.
