Apple’s official Sketch libraries are awesome. Going to make designing app screenshots much more convenient. The iOS and watchOS editions come with high quality bezel mock-ups so I can just throw a screenshot in there and be done.
But, of course, the macOS one doesn’t have a device mock-up. Obviously.
