There are several ways to take a screenshot on a Mac. The most obvious ones are if you want a full screen or if you just want part of the screen. However, there are also other options.
How to take a screenshot on Mac
To take a full screenshot on the Mac, you need to press CMD + Shift + 3 at the same time. This way the screenshot is saved as an image – by default it is saved on your desktop. If you want full screen, but just want to copy and paste an image of the screen, i.e. don’t save it, press Ctrl + CMD + Shift + 3.
Take a picture of part of your Mac screen
To take a screenshot of a particular segment, hold down CMD + Shift + 4 and a small crosshair will appear on the screen. If you don’t immediately spot the crosshairs, move your mouse or touchpad as if you were moving an ordinary cursor and you will see it. Drag the crosshair on the screen. You will start to create a box from top left to bottom right. Arrange this box so that it covers the part of the screen from which you want to take a screenshot. Release and it will take the screenshot of the game in the box. If at any time you find yourself creating a box where you don’t want it, press the escape key and it will bring you back to the normal cursor. Again, the image is saved to your desktop by default.
As with an image of the whole screen, you just need to copy to the clipboard and save a screenshot of part of the screen. Press Ctl + CMD + Shift + 4. The crosshair will appear as before and you can proceed as described above.
Take a screenshot of an individual window
If different windows are open because you are using different applications, you may want to capture an image of only one of them. To do this, press CMD + Shift + 4 + Space. A camera icon appears. Now when you hover over a window, it will be highlighted in blue. Left click on your mouse / trackpad to take a picture of the selected window.
Record your screen as a video
To see a full range of screen capture options, press Cmd + Shift + 5. A menu appears at the bottom of your screen. In addition to allowing you to do many of the things described above, this menu also allows you to record your full screen or part of it as a video. If you select the Options menu, you can adjust a new range of settings, including where your screenshots are saved and whether or not the pointer appears there.
