How to Take a Full-Screen Screenshot on Mac
Capturing one screen is a keystroke. Capturing three screens and getting something you can actually use is the harder problem, and the one most tools hand back to you as a pile of separate files.
Press ⌃+⌥+D and Snip Studio captures the display your pointer is on. No toolbar, no clicking to choose which screen.
Capture a whole display
-
Press the display hotkey
Press ⌃+⌥+D. The screen under the pointer is captured immediately and lands in your library.
Captures the display your pointer is on. It includes the menu bar, the Dock, every open window and the wallpaper.
The pointer's display is the one you get — no picking required. -
Choose how multiple displays are handled
With more than one screen connected, Snip Studio offers two modes rather than assuming:
- All displays, stitched — every connected screen composed into a single image, handling mixed resolutions and whatever arrangement you have them in.
- All displays, separate — each screen saved as its own capture.
Stitched, with the displays placed as they actually sit. -
Use a delay if you need to set the screen up
Hover the HUD and pick 3s, 5s or 10s before choosing display capture. The countdown gives you time to arrange windows, open a menu, or move the pointer somewhere sensible.
The delay applies to the next capture only. -
Check what is in it before you send it
A whole-screen capture is the one most likely to include something you did not mean to share — a notification, an open inbox, a browser tab. Snip Studio reads it on your Mac and lists the emails, URLs, file paths, faces and codes it found, so you can redact them and export a flattened Safe Copy while the original stays intact.
Bulk-redact every email or every URL in one action.
Each screen is captured at its physical pixel count. A Retina built-in display and a 1080p external monitor produce very differently sized images from the same action. Stitched mode accounts for this when composing them, so the result is not distorted.
Why full-screen captures need more care
A region capture contains what you pointed at. A full-screen capture contains everything, including things you had stopped noticing: a notification banner, a calendar invite, a Finder window with a client's name in the path, a browser with fourteen tabs whose titles are all readable.
This is the case where automatic detection earns its place. Rather than scanning the image by eye at full zoom, you get a list: 3 emails, 1 URL, 2 faces, each with a masked preview so you can tell which is which without exposing it. Redact the ones that matter, export, and the flattened copy cannot be reversed.
It is also why the free-plan mark sits in the corner rather than across the image: a full-screen capture is often a document, and a watermark through the middle of it would make it useless.
Capturing the same screen regularly
Full-screen captures are the ones most likely to be part of a routine — a dashboard at the end of each day, a monitoring view before a deploy, a status board for a report. Doing that by hand means remembering, and remembering to file it somewhere sensible.
An automation covers it. Trigger on demand with its own global hotkey, or after every capture; add conditions on the source app or the display so the rule only fires for the screen you mean; then chain the actions — recognise the text, redact anything detected, export a PDF, save it to a dated folder, and show a notification when it is done.
Because redact actions bake into everything downstream, a rule that redacts and then exports cannot write the unredacted file by accident. That matters when the capture is going somewhere shared and nobody is looking at it before it lands.
Reading a whole screen back
A full display holds a lot of text, and Snip Studio recognises all of it on capture. That makes a full-screen capture searchable in a way a photograph of a screen never is: three weeks later you can find it by an order number that happened to be visible in a corner, rather than by scrolling a folder of near-identical images.
The library's Timeline view helps here too — a calendar month grid with a fanned stack of that day's captures on each date, so "the Tuesday we had the outage" is a place you can navigate to rather than a filename you have to guess.
Capturing and the searchable library are free. Automations, the editor, recording, scroll capture and the Safari extension are part of the paid ULTRA upgrades, bought in-app through Apple.
Common problems
You got one file and expected two
Your displays are mirrored, so both show the same content and there is only one thing to capture. Check System Settings → Displays.
A full-screen app is missing from the capture
An app in full-screen mode occupies its own Space. Switch to that Space first, then capture, or use window capture to grab the app directly.
The file is very large
A 5K display is roughly 14.7 million pixels, and that is a lot of image regardless of format. Export as WebP or JPEG for sharing, or scale to 50% — both are options in the export panel, no system setting required. See how to change the screenshot format.
Part of the screen is black
Some streaming video and secure windows exclude themselves from capture at the source. No tool can override that.
The capture includes a notification you did not want
Turn on Do Not Disturb before capturing, or redact it afterwards — Snip Studio will usually have detected the email address or name inside it already.
The pointer is in the capture, or missing from it
Pointer inclusion is a capture setting in Snip Studio's preferences, so you can set it once for the kind of documentation you produce.
Frequently asked questions
How do you capture the whole screen on a Mac?
Press ⌃+⌥+D in Snip Studio. The display under your pointer is captured and lands in the library.
Can you capture two monitors as one image?
Yes. Snip Studio's all-displays mode composes every connected screen into a single stitched image, handling mixed resolutions and arrangements. There is also a separate-files mode.
How do you take a full-screen screenshot without the Dock?
Hide the Dock first, then capture — or capture the window you actually need instead, which excludes the desktop entirely.
How do you delay a full-screen capture?
Hover the Snip Studio HUD, pick a 3, 5 or 10 second preset, then choose display capture. The countdown starts immediately.
Why is my full-screen capture so big?
Retina displays capture at double resolution, so the pixel count is several times what the screen appears to show. Export as WebP or JPEG, or scale to 50%, to bring the file size down.
