Capturing a screenshot on a Mac is essential if you need to capture screen information or to share it with a particular user. There are two basic ways how to take a screenshot on a Mac: toggling the Command+Shift+4 keyboard shortcut or using the left X button. Taking a screenshot in a Finder window is best, as it can save a larger region than a normal screen.
A screenshot is saved in PNG format by default, but you can save it in other formats as well, such as JPG, TIFF, GIF, PDF, and more. Taking a screenshot in any format is easy. Just select the one that best suits your needs, and press the Shift/Option keys. You can also use the Control and Command+Shift+4 keyboard shortcuts to capture a part of the screen. Then, paste the captured image into any app and save it.
You can also select an area of the screen to take a screenshot. Hold the Command, Option, or Space keys at the same time. You can move the crosshairs to any place on the screen by releasing the mouse button. This process takes several seconds, but it works perfectly. You can also edit the image that will be saved with the screenshot. It is best to back up the screenshot before sending it to anyone. There are also several third-party programs that allow you to capture a specific portion of the screen.
