How to take a screenshot on your Mac
I’m tired of searching on google whenever I need it.
You can capture the entire screen, a window, or just a selected portion of the screen.
If you’ve upgraded to macOS Mojave or later, you can use the Screenshot app to take all types of screenshots or make video recordings of your screen. You can open Screenshot by pressing Shift-Command (⌘)-5, or use Spotlight to find and open the app.
Other keyboard shortcuts, such as Shift-Command-3 and Shift-Command-4, work in all macOS versions.
