Screen capture on Mac computers offers three methods common to all modern computers, based on keyboard shortcuts, but there is an additional way to achieve this for those laptops equipped with Touch Bar.
In addition to the keyboard shortcuts common to all computers there is also available a method unique to MacBooks with Touch Bar
With each of these methods there is also the ability to add different features to these screenshots, including whether they are of the entire screen or just a portion of the screen. There is even the possibility to use shortcuts to save, delete or open these screenshots.
When taking screenshots they will appear for a few seconds in reduced size at the bottom right of the screen, from where they can be opened directly for editing by clicking on them with the cursor, being stored on the desktop.
-Command + Shift + 3: This key combination activates a full screen capture. It is the most commonly used keyboard shortcut for captures.
-Command + Shift + 4: With this key combination the cursor is transformed into a cross that allows you to cut out the space of the screen that you want to cut out. You only need to drag the mouse, outlining the part of the screen you want to capture in the form of a rectangle, and when you release the mouse, the capture will be completed. Once the capture has been made, different options are opened:
-Click and release the space bar: The mouse cross becomes a camera icon that allows, when placed over an open window, to capture it.
-Click and hold down the space bar: allows to resize the selected area, in case the initially selected area needs to be adjusted
-Hold down the Shift button (after pointing to the capture area and before releasing the mouse button or the trackpad): This option keeps the side margins of the marked area fixed, allowing you to move the mouse up or down to adjust the top and bottom margins.
-Release the Shift key (without releasing the mouse or trackpad) and press it again: With this action the selected area can be repositioned.
-Command + Shift + 5: This option was added with macOS Mojave in 2018 and allows a small panel to appear at the bottom of the screen showing different options related to the screenshot taken: capture the entire screen, just a window, just a selection of the screen. It also allows you to select the destination of the screenshot (Desktop, Documents, Clipboard, Mail, Messages, Preview or other location.
-Command + Shift + 6: Only users of MacBook computers equipped with TouchBar have this option, which allows you to capture what is being displayed by TouchBar, the dynamic touch screen that appeared as an option on some Apple laptops (the previous MacBook Pro 15 and MacBook Pro 16 or the current MacBook Pro 13).
