I'm looking for a screen capture app for macOS that is similar to the free Grab IT utility , but automatically generates a file name ( say "YYYYMMDD_HHMMSS.png") for me. That way I can focus on what I'm doing and not have to stop everything to select a file save location and a unique name for each file while writing a Wiki page or whatever that uses the screenshots. It ideally * Saves desktop, window, or selected area of screen * generates a unique file name automatically * save the file in predefined location * Can be free or paid, either is fine. * Runs on macOS Sierra or higher * ( optional ) the developer / project isn't likely to stop supporting the app. And that's it!
