How to take screenshots on your Mac

Screenshots are extremely useful. You can use them to demonstrate how to use a new app to your grandmother. You can use them to send a screenshot of that unusual error message to the IT department at your workplace. You can use them to collect tweets before they go into the abyss of oblivion

Each of the major operating systems — Windows, macOS, Android, and iOS — has a method for taking screenshots. Here’s how to take screenshots in all four of them quickly and easily.

SCREENSHOTS ON A MAC

The Screenshot program is available in current macOS versions (Mojave and Catalina) and may be opened by pressing Shift-Command ()-5.

You will see a command bar with a number of options. You can capture a screenshot of the entire screen, a window, or a specific selection; you can also record all or portions of your screen using a video camera. You can pick where you want to store your screenshot by clicking the “Options” button, and you can also specify a short delay. When you’re ready, click the “Capture” button on the command bar’s right end.
You can still save screenshots to your desktop as PNG files if you haven’t upgraded to Mojave or Catalina.

• Press Shift-Command-3 to snap a screenshot of the entire screen.
• To capture a portion of the screen, hold down Shift-Command-4 and then drag the pointer about the screen to delineate the area you wish to capture.
• Using Shift-Command-4, you can grab a certain window. Press the spacebar once more. The cursor will take on the appearance of a camera. Hover your cursor over the window you wish to capture until it glows, then click on it.
