This macOS Sierra UI Kit is designed at 1x scale, but with retina displays in mind! So if you open this on a non-retina screen it may looks a little blurry. I think we're missing some good retina UI Kits for Mac, so I've created this based on Apple's fine retina display style. Any feedback is appreciated! Just take a look at the issues, or leave me a comment on dribbble or Product Hunt.
