If you want to take a screenshot on your Mac, there are a few different ways to go about it. The first is to use the keyboard shortcuts, which are Command+Shift+3 (to take a screenshot of the entire screen) and Command+Shift+4 (to take a screenshot of just the active window). If you want to crop the screenshot, you can do so by using the Crop tool in the Photos app. To access it, click on the Photos app icon in your Dock and then select Crop. Once you’ve cropped the screenshot, you can save it to your computer or share it with others. ..
