We already known that Command-Shift-3 will capture a screenshot of entire screen. But if you have 2 or more display screens, "entire" also means "all of them".

The question is: Is there anyway (or is it possible) to force Command-Shift-3 capture screenshot of primary display only if I have more than 1 display screen?

Any help would be appreciated.

To capture one window

⌘ Command +⇧ Shift+4+Space and click on the window you would like to capture. The window to be captured will be highlighted.

Other screenshot shortcuts

⌘ Command +⇧ Shift+3: Screenshot entire screen
⌘ Command +⇧ Shift+4: Screenshot a selected area. Click and drag to select an area to screenshot.
⌘ Command +⇧ Shift+4+Space: Screenshot one window or menu.

To save a screenshot to your clipboard and not Desktop, use Control in addition to the shortcuts defined above. When a screenshot is saved to your clipboard, you can paste the screenshot into a document, spreadsheet etc etc.

Apple provides an article on taking screenshots here: How to take a screenshot on your Mac


There are 4 basic screenshot commands:

  1. SHIFT+COMMAND+3 = SCREENSHOT FILE (jpg or tiff) of OF ENTIRE screen (or all of all displays if more than 1)
  2. SHIFT+CTRL+COMMAND+3 = Clipboard (copied)image of HIGHLIGHTED area of screen
  3. SHIFT+COMMAND+4 = SCREENSHOT FILE (jpg or tiff) of HIGHLIGHTED area of screen
  4. SHIFT+CTRL+COMMAND+4 = Clipboard (copied)image of HIGHLIGHTED area of screen

Using 2 & 4 (above) allows you to choose the area of the display (or displays) that you want.

alternatively, your display screenshots USUALLY end up being 2 separate images - you could just take the image, then delete the one you don't need...
