app-capture
Use when you need to SEE the Mac you are working on — a screenshot of an app's window, a region of the screen, or a rendered web page — or when a capture comes back looking wrong (a picture of the wallpaper, a window with something across it, a postage stamp instead of a window), or when the capture server does not answer at all and the app has to be installed or updated. Covers every tool — stills, video, keystrokes — presets that give a set of shots one look, staging a window before the shot (hide the rest, centre, fit, exact size, all restored afterwards), poster backdrops staged behind the window so its shadow and glass are real, where to download the app and how it keeps itself current, and the refusals, which are the most useful thing this tool says.
