If you have a Mac, this guide will show how to make a full screen image capture, how to grab a precise part of the screen or a window, how to add markup to a screenshot, and discuss the dedicated screen capture utility in OS X plus a few popular apps that could make the process quicker and easier on Mac computers.
How to capture the whole screen on your Mac
Full display screenshots are ideal when you need to quickly capture information on your screen like an important email, payment receipt, or sending an error message on your desktop to your IT support team.
While Windows fans can boast the dual-key convenience of control and print screen, Mac users need to employ an extra digit to capture the entire screen. Here’s a quick step by step explanation of how to take a full screenshot on a Mac:
Ensure you set up the screen to only display exactly what you would like to capture because any icons and open documents you’d prefer to be omitted will appear in the screenshot
Press and hold the command and shift buttons on your keyboard and then tap the 3 key.
Your Mac will make a short camera shutter sound and then automatically save your screenshot as a new PNG image file on your desktop labelled as ‚Screen Shot‘ followed by the date and time.

Alternatively, you can get around the automatic image save function by also holding the control key during step 2 above. This four-key combination will copy the image to the clipboard similar to the print screen function on Windows.

How to capture part of your Mac’s screen
Being able to capture just a portion of your screen means you can create images of specific windows and parts of websites, and leave out all the personal and distracting parts like the taskbar, system date and time, and other open windows on your desktop.

Upon releasing the mouse button, your Mac will make a sound like it’s taking a photo and then you will see a new PNG image file saved on your desktop. It will be labelled with ‚Screen Shot‘ followed by the date and time.
Note: If you make a mistake and click the wrong starting point during step 3, simply tap the escape key to exit the screenshot and return your cursor to normal mode.

Markup is useful if you want to make quick notes for designers, make corrections to homework, or mark areas of interest within html code to website developers.
These steps show you how to add markup to screenshots without first saving the screenshot and then having to use image editing software:
