Grab (software)
On macOS versions 10.13 and earlier, Grab is found in the folder "Utilities", which is a subdirectory of "Applications". It may be quickly opened by using the Spotlight function when entering "grab", or by pressing and typing "/Applications/Utilities/Grab.app" in Finder. It was previously also found in the Finder menu under "Services" > "Grab". As of Mac OS X v10.4, Preview had a "Grab" submenu in the File menu, with selection, window, and timed screen. The menu was renamed to "Take Screenshot" in more recent versions of macOS. Grab saves screenshots in the Tagged Image File Format (TIFF). In macOS, it is also possible to save screenshots directly to the Desktop in PDF format (earlier versions of macOS) or PNG format (later versions), using keystrokes shown below. For DRM reasons, it is not possible to use this software while DVD Player is open. Grab helps determine the size of an element on the screen. After using the selection feature and capturing the screen, one can select Inspector from the menu or press (or ); a dialog box will appear with the dimensions of the selected area.
