This is one of the most comprehensively designed Yosemite UI KitDesigned exclusively for Sketch 3.
All UI elements (well, besides the OS X 10.10 icons) have been redrawn and restyled as accurately as possible.With all UI elements drawn using vectors at 2x, everything will scale beautifully.OS X Yosemite has been released so the UI is pretty much set but I will keep an eye on it and update as necessary.
Download and use as you choose! Please don’t redistribute the kit.
