If you’re like most people, you probably use a Mac to do a lot of things. But there are some things you can’t do on a Mac. For example, you can’t screenshot or crop images. But there are other ways to do things on a Mac. For example, you can use the Finder to open files and folders, or the System Preferences to change how your computer works. To take a screenshot or crop an image on your Mac, first open the Finder and click on the three lines in the top left corner of the screen. Then click on the three lines in the bottom left corner of the screen and select “Screenshot.”
