The new MacBook Pro with Touch Bar has replaced the standard Escape and Function keys with a little dynamically changing screen called the Touch Bar. Some Mac users may wish to take a screenshot of the Touch Bar, perhaps for developing, testing, or sharing purposes, similar to screenshotting displays on any other Mac or iOS device.
There are two different keyboard shortcuts to capture screen shots of Touch Bar on a Mac. One saves the Touch Bar screenshot as a file on the desktop, and the other copies a picture of the Touch Bar to the Mac clipboard instead. You can also take screenshots of the Touch Bar with the Grab application in Mac OS.
