To take a screenshot on a Mac, you'll need to memorize the keyboard shortcuts, which are command + shift + 3 for full-screen, command + shift + 4 with space and then clicking on the window for single windows, and command + shift + 6 for Touch Bar screenshots. You can also customize these shortcuts from your Mac's keyboard preferences. The Screenshot app comes with the ability to record screens, capture delayed screenshots, and save them directly to a specific location. Additionally, there are third-party tools like Zappy that offer more advanced features such as automatic web upload.
