- Set up the desktop
Open the program, game or folders you want to screenshot, and arrange them accordingly on the desktop. Alternatively, leave the desktop as-is if you want to capture your Mac theme and desktop wallpaper.

Press Command, Shift and 3, and release the keys to capture the desktop. To capture a selected area, press Command, Shift and 4, and drag the crosshair over the area. Release the mouse button to take a screenshot. To screenshot a single window, press Command, Shift and 4, and then release the keys. Tap Space, and click on the open window.
- View the screenshot
Locate the new PNG file on your desktop. To view the screenshot, double-click the file to launch it in Preview or the image viewer of your choice. You can then email the screenshot or upload it for review. Close the image viewer when done. Delete the screenshot from the desktop, or transfer it to your Pictures folder.
